Substitute Part Grouping Explanation
Substitution of the 74LVC02APW,112 is determined by the following critical parameters:
- Logic Function: All substitutes must implement 4-channel 2-input NOR gate functionality
- Package Type: 14-TSSOP or 14-SSOP surface mount packages are acceptable
- Output Drive Capability: 24mA output current (high and low) is the standard requirement
- Supply Voltage Compatibility: Operating voltage range must encompass the application requirements
- Propagation Delay: Maximum delay specifications determine signal timing performance
- Operating Temperature: Extended temperature range (-40°C to 125°C) is required for industrial applications
- Compliance: RoHS3 compliance and MSL Level 1 are standard requirements
Substitute parts are grouped into two categories: direct manufacturer equivalents from Texas Instruments (74LVC series) and compatible alternatives from onsemi and Fairchild Semiconductor (74LCX series). Both series meet the core functional and electrical requirements while offering different quiescent current characteristics and temperature specifications.

Engineering Selection Recommendations
Primary Substitutes (Highest Compatibility)
SN74LVC02APWR and SN74LVC02APWT from Texas Instruments are the preferred direct substitutes. Both are active products in 14-TSSOP packaging with extended temperature range (-40°C to 125°C), matching the original part's operating specifications. These parts feature lower quiescent current (1 µA) and faster propagation delay (4.2ns) compared to the obsolete Nexperia part, providing improved power efficiency and signal timing performance. Both are RoHS3 compliant with MSL Level 1 rating.
Alternative Substitutes (Compatible with Voltage Constraints)
MC74LCX02DTR2G and 74LCX02MTCX from onsemi and Fairchild Semiconductor are active alternatives in the 74LCX series. These parts operate within the 2V to 3.6V supply range and are suitable for applications not requiring the extended 1.2V minimum voltage of the original part. The 74LCX series offers lower quiescent current (10 µA) but operates at reduced temperature range (-40°C to 85°C), making them suitable for commercial and industrial applications within this thermal envelope.
Automotive-Grade Option
SN74LVC02AQPWRG4Q1 is an AEC-Q100 qualified automotive-grade variant from Texas Instruments. This part is suitable for automotive and harsh environment applications requiring qualification documentation and extended reliability assurance.
Avoid
SN74LVC02APWE4 is discontinued at DiGi Electronics and should not be selected for new designs despite active manufacturer status.
Frequently Asked Questions (FAQ)
Q: Can I use 74LCX02 series parts as direct replacements for 74LVC02APW,112?
A: The 74LCX02 series (MC74LCX02DTR2G, 74LCX02MTCX, MC74LCX02DTG) are functionally compatible but have a minimum supply voltage of 2V compared to the original part's 1.2V minimum. Use these substitutes only if your application operates at 2V or higher. Both series provide identical logic functionality, output drive capability, and package compatibility.
Q: What is the difference between 14-TSSOP and 14-SSOP packaging?
A: Both are surface mount packages with 14 pins and similar footprints. 14-TSSOP (thin shrink small outline package) has a width of 0.173" (4.40mm), while 14-SSOP (shrink small outline package) has a width of 0.209" (5.30mm). SN74LVC02ADBR uses 14-SSOP packaging and requires PCB layout adjustment compared to 14-TSSOP variants. Verify your PCB design accommodates the package width before selection.
Q: Which substitute offers the best power efficiency?
A: SN74LVC02APWR, SN74LVC02APWT, and SN74LVC02APW all feature 1 µA quiescent current, providing superior power efficiency compared to the original 40 µA specification. The 74LCX02 series offers 10 µA quiescent current, a middle ground between the original and the lowest-power alternatives.
Q: Are all substitutes RoHS3 compliant?
A: All listed substitutes are RoHS3 compliant with MSL Level 1 (unlimited moisture sensitivity), matching the original part's environmental compliance requirements.
Q: Can I use SN74LVC02AQPWRG4Q1 in non-automotive applications?
A: Yes. SN74LVC02AQPWRG4Q1 is an automotive-grade variant with AEC-Q100 qualification. It meets all standard 74LVC02 electrical specifications and can be used in any application requiring the extended temperature range (-40°C to 125°C) and automotive reliability assurance. This part carries additional qualification documentation suitable for safety-critical applications.
Q: What is the inventory status of these substitutes?
A: All listed substitutes are in active stock. SN74LVC02APWR has the highest inventory (3,455 pcs), followed by 74LCX02MTCX (19,465 pcs). Verify current availability with your supplier before design finalization.
