Substitute Part Grouping Explanation

Substitution for the 74AXP1T34GWH is determined by the following critical parameters:

Logic function: Non-inverting buffer operation
Package compatibility: 5-TSSOP / SC-70-5 / SOT-353 form factor
Output configuration: Push-pull output stage
Supply voltage range: Minimum 0.7V support required
Output current capability: Minimum 12mA per output
Operating temperature range: -40°C to 85°C minimum
RoHS3 compliance and MSL-1 rating

Substitute parts are grouped into two categories:

Direct Substitutes (Same Package, Compatible Parameters): Parts maintaining the 5-TSSOP package with equivalent or superior electrical specifications.

Functional Equivalents (Alternative Packages): Parts with identical logic function and electrical performance but different package form factors, suitable when PCB layout permits package variation.

Engineering Selection Recommendations

Primary Substitute: SN74AUP1T34DCKR (Texas Instruments)

The SN74AUP1T34DCKR is the recommended direct substitute. It maintains identical package form factor (5-TSSOP / SC-70-5), logic function (non-inverting buffer), and output configuration (push-pull). The part is in active production status, ensuring long-term availability. Supply voltage range (0.9V ~ 3.6V) encompasses the 74AXP1T34GWH operating window. Output current specification (6mA) is lower than the original 12mA; applications requiring full 12mA output should be evaluated against actual load requirements. ROHS3 compliance and MSL-1 rating match the original part.

Alternative Substitute: SN74AUP1T34QDCKRQ1 (Texas Instruments, Automotive Grade)

This variant offers identical electrical and package specifications to the SN74AUP1T34DCKR with extended operating temperature range (-40°C to 125°C) and AEC-Q100 automotive qualification. Selection is appropriate for applications requiring automotive-grade components or extended temperature operation.

Functional Equivalent: FXLP34P5X (onsemi)

The FXLP34P5X provides equivalent functionality in the same 5-TSSOP package. Classified as a voltage level translator with unidirectional, non-inverted output, it delivers the required logic translation function. Supply voltage range (1V ~ 3.6V) and operating temperature (-40°C ~ 85°C) are compatible. This part is in active production status. Output current specifications are not provided in the datasheet parameters; verification against application requirements is necessary.

Package Variant: NLSV1T34MUTBG (onsemi, 6-UDFN)

This part provides non-inverting buffer functionality with higher output current capability (24mA) in a 6-UDFN package. Selection is appropriate only when PCB layout accommodates the alternative package form factor. Product status is obsolete, limiting long-term procurement viability.

Frequently Asked Questions (FAQ)

Q: Can SN74AUP1T34DCKR directly replace 74AXP1T34GWH without circuit modification?

A: Yes, for most applications. Both parts share identical package (5-TSSOP), logic function (non-inverting buffer), and output type (push-pull). The primary difference is output current: SN74AUP1T34DCKR provides 6mA versus the original 12mA. If the application load requires the full 12mA output current, circuit performance must be evaluated. Supply voltage range compatibility (0.9V ~ 3.6V for the substitute versus 0.7V ~ 2.75V for the original) is sufficient for standard logic applications.

Q: What is the difference between the standard SN74AUP1T34DCKR and the SN74AUP1T34QDCKRQ1?

A: Both parts are electrically and functionally identical. The QDCKRQ1 variant includes AEC-Q100 automotive qualification and extends the operating temperature range to -40°C ~ 125°C. Selection depends on application requirements: standard industrial applications use the DCKR variant; automotive or extended-temperature applications use the QDCKRQ1 variant.

Q: Is FXLP34P5X suitable as a substitute?

A: FXLP34P5X provides equivalent non-inverting buffer functionality in the same 5-TSSOP package and is in active production. However, it is classified as a voltage level translator rather than a standard logic buffer. Output current specifications are not provided in the available parameters. Use this part only when output current requirements are confirmed compatible through detailed datasheet review.

Q: Why is NLSV1T34MUTBG listed if it uses a different package?

A: NLSV1T34MUTBG is included as a functional equivalent for applications where PCB layout permits package substitution. It provides superior output current capability (24mA) and maintains non-inverting buffer logic. However, the 6-UDFN package requires PCB redesign. Additionally, this part is obsolete, making it unsuitable for new designs or long-term procurement.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance and MSL-1 (unlimited) moisture sensitivity rating, matching the original 74AXP1T34GWH specifications.

Q: What should I consider when selecting between substitute options?

A: Prioritize active production status for long-term availability. SN74AUP1T34DCKR is the recommended choice for standard applications. Verify output current requirements: if 6mA is insufficient, evaluate NLSV1T34MUTBG (24mA) or confirm application tolerance. For automotive applications, select SN74AUP1T34QDCKRQ1. Confirm package compatibility with existing PCB layout before finalizing selection.
