How to Read a Texas Instruments Orderable Part Number

Match the complete TI part number to its exact ordering row, then use that product family’s naming convention to explain each field. Confirm the device option, package, grade, material information and packing before purchase.

A generic product number helps you find the family. The full orderable part number identifies what you intend to buy. Do not approve a different suffix using a decoder borrowed from another TI family.

What Is the Difference Between a TI GPN and an OPN?

A generic product number (GPN) groups a product’s orderable options. An orderable part number (OPN) identifies a specific ordering configuration within that group. TI explains this relationship in its product lifecycle guidance.

For example, SN74LVC1G08 identifies a single two-input AND gate. Adding DBVR or DBVT selects the ordering options shown here. Both use the same five-pin package, but the listed carrier quantities differ.

Keep the full OPN on the approved bill of materials (BOM), quotation and purchase order (PO). Store a supplier’s stock code in a separate field; it should not replace the manufacturer number.

One GPN, two ordering options

SN74LVC1G08GPN: the product group
SN74LVC1G08DBVROPN: SOT-23 (DBV), 5 pins; 3,000 pieces / large tape-and-reel
SN74LVC1G08DBVTOPN: SOT-23 (DBV), 5 pins; 250 pieces / small tape-and-reel

TI lists the pair as carrier alternatives. View the exact TI ordering record.

How Do You Decode a Texas Instruments Part Number?

Use these examples to learn the method, not a universal suffix alphabet. Each explanation is tied to a named TI product and its official record.

How Do DBV and R Identify the SN74LVC1G08 Ordering Option?

SN74LVC1G08Generic product

DBVSOT-23 package, 5 pins

RLarge tape-and-reel option in this family

The DBVT option retains the DBV package but changes the listed packing configuration. That makes it a candidate for a manufacturing and purchasing review—not an automatic change to your approved BOM.

The important limit: R does not establish one reel quantity across the TI portfolio. Retrieve the complete OPN’s quantity and carrier fields. Compare the DBVT ordering option.

Why Does TMS3705DDRQ1 Contain Two Different D Fields?

TMS3705Transponder base-station family

DSilicon revision

DSOIC package, 16 pins

RLarge reel

Q1Q100-qualified option

The first D after the family is a revision field; the next D is a package field. TI defines their positions in TMS3705 Rev. F, Section 11.2. A familiar letter means little without its position.

The revision affects the application. TI recommends the D and G variants for AES transponders and states that E and F cannot be used with AES transponder products. Its description also names TMS3705GDRQ1 as the replacement for TMS3705DDRQ1. See the compatibility statement on page 1.

Buyer action: identify the actual transponder system and the complete offered OPN before approving a revision change. A shared family and SOIC outline do not settle functional compatibility. Q1 also does not establish every application requirement or one universal temperature range.

Which Details Must You Look Up for LM324APWRG4?

Search the full LM324APWRG4 string. Keep the A in LM324A: a broader LM324 family document covers several variants, so a specification mentioned elsewhere in that document is not automatically the specification for this OPN.

TI’s exact part page also lists LM324APWRG4.A in its “Same as” field. That documented relationship is useful; it does not mean every dot suffix on every TI part can be ignored. Keep the quoted identifier and the published mapping together.

Check the LM324APWRG4 record and quality information.

GPN: LM324A
Package: TSSOP, TI code PW, 14 pins
Standard pack: 2,000 pieces / large tape-and-reel
Temperature: 0 to 70 °C, as listed for this OPN
Lead finish: NiPdAu, as listed in the part record

More complex processors need their own naming table. AM62x uses separate fields for revision, speed, features, functional safety, security, temperature, package and automotive designation. Do not apply a simple logic-device pattern to a processor. AM62x Rev. C, Section 9.1.2 defines the fields and footnotes.

Can You Remove G4, E4 or /NOPB from a TI Part Number?

Do not delete a suffix from an approved OPN by assumption. Establish the relationship between the two complete numbers, then check whether the documented difference affects your material, assembly or customer requirements.

TI’s labeling guidance connects e-codes with lead-finish categories and uses G-codes for products that also meet its Green requirements. G4 is a finish-category clue, not a complete material declaration. Preserve /NOPB as part of the ordering identity too; use the exact part’s RoHS, material and lead-finish records for the purchase review. See TI’s labeling definitions.

If a record lists more than one permitted finish, do not assume it identifies the finish of the offered lot. Ask how the supplier will establish the particular finish when your approved specification controls it.

A documented G4 replacement with a material condition

Historical TI PDN 20210125004.3 lists SN74HC74PWRG4 → SN74HC74PWR. Its replacement code S denotes functional and parametric equivalence, but the notice also says NiPdAu could no longer be guaranteed following a BOM change. Replacement material could carry G3 or G4 finish categories, identified on the shipping label.

What follows: electrical equivalence does not close a controlled finish requirement. Review the notice and lot evidence before accepting the replacement. This case applies to the listed HC devices, not all G4/E4 parts.

TI PDN, pages 3–4: reason, affected parts and replacement-code definitions. This is a manufacturer notice, not a YURUNOX shipment case.

How Do You Check the Package, Reel Quantity and Carrier Format?

The package is the component body and terminals. Packing is how those components are supplied—in a reel, tape, tube or tray. Approve both: the right electrical device can still arrive in a format your line has not accepted.

Will the Package Fit the PCB and Assembly Process?

Match TI’s package code, pin count and mechanical drawing to the approved footprint. Check terminal arrangement, body dimensions, pin-one reference and any exposed pad or ball pattern. A package name alone is not a footprint approval.

For example, “TSSOP, PW, 14 pins” is more useful in an approval record than “surface-mount IC.” Keep the applicable drawing with the part record so engineering and manufacturing can check the same dimensions.

TI’s packaging resources provide entry points for package, marking and carrier information.

Does the Standard Pack Quantity Match What the Supplier Will Ship?

Not necessarily. Standard pack quantity is a manufacturer packing attribute—not automatically the supplier’s minimum order quantity (MOQ), your ordered quantity or proof of an unopened factory reel.

Ask whether delivery will be a full factory reel, custom reel, cut tape, partial reel, tube, tray or repack. Agree quantity per carrier, lot segregation, original-label availability and any changes in packing. TI describes custom reels and cut tape as separate carrier arrangements; another supplier’s service must be confirmed on its own terms.

Tubes and trays can also suit automated assembly when the line has compatible feeding equipment. Manufacturing should review the actual delivery format instead of accepting or rejecting it by name.

Scroll within the table on a small screen. Sources: SN74LVC1G08 ordering and carrier information and LM324APWRG4. These are not stock or delivery commitments.

Which Tape Dimensions and Orientation Does the Feeder Need?

For tape-fed assembly, use the applicable packing drawing to check tape width, pocket pitch and dimensions, reel dimensions and component orientation. Confirm leader and trailer arrangements when custom reels are proposed.

TI’s LM324APWRG4 packing rows list nominal values of 330 mm reel diameter, 12 mm tape width and 8 mm pocket pitch, with pin-one quadrant Q1.

Here, Q1 means orientation quadrant 1 in the “Pin1 Quadrant” column—not automotive qualification. Read the column heading and diagram, not just the cell. See the LM324 packing table and orientation key.

Can the Chip Marking Confirm the Complete TI Part Number?

Not by itself. Several orderable numbers can share a device marking while using different packing options. The top mark cannot reconstruct information that the manufacturer does not print on the device.

LMK04001 options with the same listed K04001BI marking
Exact OPN	Listed device mark	Standard pack	Package / pins
`LMK04001BISQ/NOPB`	`K04001BI`	1,000 pieces	WQFN (RHS) / 48
`LMK04001BISQE/NOPB`	`K04001BI`	250 pieces	WQFN (RHS) / 48
`LMK04001BISQX/NOPB`	`K04001BI`	2,500 pieces	WQFN (RHS) / 48

On a small screen, scroll within the table to see all columns. Selected rows from the LMK04001 package addendum. Its marking footnote allows additional logo, trace-code or environmental information; the table is not a complete drawing of every printed line.

At receiving, compare the accepted OPN with the manufacturer pack label, package, quantity and purchase record. Keep lot identification connected to the material during unpacking and kitting. A matching mark or label is an identity check, not proof of authenticity by itself.

If the label, mark and PO disagree: segregate the affected material, retain photos and original labels, and request a documented explanation. The difference could reflect a legitimate identifier or a wrong item; do not assume either conclusion or release the material while the mismatch remains unresolved.

What Should You Do When a Supplier Offers a Different TI Suffix?

Keep the requested and offered OPNs on separate lines. First establish what changed; then obtain approval from the team responsible for that difference. A packing change, silicon change and material change do not need the same review.

A verified carrier-only difference goes to manufacturing and the purchasing or quality owner defined by your process. Changes to function, revision, package, grade or controlled materials also need the appropriate technical review. If the evidence does not explain the difference, keep the offer open as an unapproved alternate.

A 1,000-board build: DBVR or DBVT?

Illustrative planning example, not a YURUNOX customer case. Assume one SN74LVC1G08 per board and no assembly or spare allowance.

1,000 boards × 1 part/board = 1,000 parts. Four standard 250-piece DBVT reels cover that bare requirement. One standard DBVR pack contains 3,000 pieces. Neither calculation establishes a supplier MOQ or a quoted shipment format.

1. Preserve both identities

Record the BOM’s SN74LVC1G08DBVR and the offered SN74LVC1G08DBVT. Attach TI’s carrier comparison instead of shortening both to the GPN.

2. Clarify the shipment

Confirm reel count, quantity per reel, lot policy and any cut-tape or custom-reel arrangement. Add the actual assembly allowance before fixing the order quantity.

3. Approve the change

Manufacturing reviews feeder handling. The assigned quality and purchasing owners confirm pack identification and any controlled delivery exceptions.

4. Receive the approved option

The PO names the accepted OPN and packing. Receiving checks against that agreement, not a verbal statement that the parts are “the same.”

How Do You Verify a TI Orderable Part Number Before Purchase?

Use a short evidence trail that another buyer or engineer can repeat. A readable code is the start; an exact, documented ordering match is what makes the review useful.

Capture the complete manufacturer number.
Preserve every letter, number, slash, hyphen and dot from the approved source. Check likely transcription errors against the original BOM or label rather than silently correcting them.
Find the exact TI ordering row.
Use the part-details page and the family’s package option addendum. Compare the full string, including all suffixes. If there is no exact match, ask for the relevant archived record or written TI clarification; do not construct a plausible OPN.
Explain the fields and record the conditions.
Use family-specific nomenclature, electrical specifications and package/packing records. Save the document revision and relevant addendum date. Record any unresolved grade, material, revision or carrier difference.
Check status and applicable change notices.
Record the exact item reviewed, lifecycle status and check date. Review applicable product change notifications (PCNs) and product discontinuance notifications (PDNs). Separately confirm supplier quantity and delivery; active status is not an immediate-stock promise. TI defines the lifecycle categories here.
Agree the purchase and receiving record.
Put the accepted OPN, quantity, actual packing, traceability requirements and approved deviations on the PO. Unexplained code differences, missing controlled material evidence or label-to-PO mismatches need a named owner and resolution before release.

RFQ wording to accompany your BOM

Use the following text as a starting point. Add the exact quantity, required date and any application-specific acceptance requirements; it does not replace your company’s approval process.

Please quote the complete Texas Instruments orderable part number on the attached BOM. Preserve every suffix and separator, and keep your stock code in a separate field.

Confirm package code, pin count, supplied quantity, carrier format, quantity per carrier, and whether delivery is a full factory pack, custom reel, cut tape, partial pack or repack.

State available source traceability, lot/date-code information, original-label availability, packaging and handling condition, and the proposed delivery schedule.

List each alternate OPN or packing exception separately. Include the applicable TI ordering record, material information and change notice needed to explain the difference. Do not substitute or ship an alternate without our written approval.

Confirm that shipment labels and agreed documents will identify the accepted OPN and delivery configuration.
