SN74LVC125APWR-P Equivalent & Substitute Parts

Part Overview

The SN74LVC125APWR-P is a non-inverting buffer logic integrated circuit manufactured by Texas Instruments, designed for 3-state output applications in low-voltage CMOS environments. This device operates across a supply voltage range of 1.65V to 3.6V and is housed in a 14-TSSOP surface mount package. The part maintains Active product status and is RoHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity).

Substitute parts are identified when they maintain identical electrical characteristics, mechanical compatibility, and functional specifications. Alternative models become necessary when the primary part experiences inventory constraints, extended lead times, or when design requirements mandate specific certifications such as automotive qualification or alternative packaging formats.

Substitute Part Grouping Explanation

Substitution eligibility for the SN74LVC125APWR-P is determined by strict parametric matching across the following critical criteria:

Electrical Compatibility Requirements:

  • Logic Type: Buffer, Non-Inverting (4 elements, 1 bit per element)
  • Output Configuration: 3-State output
  • Output Current Capability: 24mA high and low
  • Supply Voltage Range: 1.65V ~ 3.6V
  • Operating Temperature Range: -40°C ~ 125°C

Mechanical Compatibility Requirements:

  • Package Type: 14-TSSOP surface mount
  • Physical Dimensions: 0.173" width, 4.40mm width
  • Mounting Method: Surface Mount

Compliance Requirements:

  • RoHS3 Compliance: Required
  • Moisture Sensitivity Level: 1 (Unlimited)
  • Product Status: Active

All identified substitute parts maintain these exact specifications. Variations in base product number (74LVC125 vs. 74LVC126 vs. CLVC125 vs. CLVC126), packaging format (Bulk, Cut Tape, Tape & Reel), and automotive qualification (AEC-Q100) do not affect functional or mechanical interchangeability when these core parameters remain constant.

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the SN74LVC125APWR-P. Selection among these alternatives is based on product availability, packaging requirements, and compliance certifications rather than functional differences.

For Standard Industrial Applications: The 74LVC125APW/C5J (Nexperia USA Inc.) offers the highest inventory availability at 115,688 pieces and is suitable for general-purpose non-inverting buffer applications requiring 3-state output control across the 1.65V to 3.6V supply range.

For Automotive and Mission-Critical Applications: The SN74LVC125AQPWRQ1, CLVC125AQPWRG4Q1, and CLVC126AQPWRG4Q1 carry AEC-Q100 automotive qualification, meeting stringent reliability and quality standards for automotive-grade electronic systems. These parts are recommended when design specifications mandate automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can SN74LVC125AQPWRQ1 replace SN74LVC125APWR-P in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The primary differences are packaging format (Tape & Reel vs. Prototype) and automotive qualification (AEC-Q100). No circuit modifications are required.

Q: What is the difference between 74LVC125 and 74LVC126 base product numbers?

A: Both base product numbers maintain identical electrical specifications for this application: 4-element non-inverting buffers with 3-state output, 24mA output current, and 1.65V to 3.6V supply voltage operation. Substitution between these base numbers is functionally valid.

Q: Are Nexperia 74LVC125APW/C5J and Texas Instruments SN74LVC125APWR-P interchangeable?

A: Yes. Both manufacturers produce parts with identical electrical and mechanical specifications. The 14-TSSOP package, output current ratings, supply voltage range, and operating temperature are equivalent. Nexperia parts are suitable for direct substitution.

Q: Does AEC-Q100 automotive qualification affect compatibility with standard industrial designs?

A: No. AEC-Q100 qualification indicates enhanced reliability testing and quality assurance but does not alter electrical or mechanical specifications. Automotive-qualified parts (CLVC125AQPWRG4Q1, CLVC126AQPWRG4Q1, SN74LVC125AQPWRQ1) are fully compatible with standard industrial applications.

Q: What does MSL Level 1 (Unlimited) mean for moisture sensitivity?

A: MSL Level 1 indicates the component has unlimited shelf life without moisture bake-out requirements. All substitute parts carry this same MSL rating, eliminating moisture-related handling constraints.

Q: Can I use 74LVC125APW/C5J in high-volume production requiring Tape & Reel packaging?

A: The 74LVC125APW/C5J is supplied in Bulk packaging. For Tape & Reel format in high-volume production, use CLVC125AQPWRG4Q1, CLVC126AQPWRG4Q1, or SN74LVC125AQPWRQ1, which are specifically packaged for automated assembly lines.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry RoHS3 compliance certification, meeting environmental and hazardous substance restrictions for electronic components.
