Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC151M96E4 is determined by the following critical parameters:

Circuit configuration (1 x 8:1 multiplexer function), output current specifications (5.2mA high and low), supply voltage range (2V ~ 6V), operating temperature range (-55°C ~ 125°C), package type (16-SOIC), and surface mount mounting type. All substitute parts listed maintain these electrical and mechanical specifications. Packaging format variations (Tape & Reel versus Bulk) and product status differences do not affect functional equivalence but may impact procurement and logistics considerations.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing production, CD74HC151M96 (Texas Instruments, Active status) is the primary recommended substitute, offering identical electrical specifications, ROHS3 compliance, and active product status ensuring long-term availability.

MC74HC151ADR2G (onsemi, Active status) and 74HC151D,653 (Nexperia USA Inc., Active status) provide functionally equivalent alternatives with ROHS3 compliance and active product status. The Nexperia part operates across a narrower temperature range (-40°C ~ 125°C) compared to the original specification (-55°C ~ 125°C); this difference is acceptable for applications not requiring extended low-temperature operation.

74HC151D-Q100,118 (Nexperia USA Inc., Automotive grade, AEC-Q100 qualified) is suitable for automotive applications requiring qualification documentation.

CD74HC251MT (Texas Instruments, Last Time Buy status) and MC74HC251ADR2G (onsemi, Active status) are parametric equivalents with identical electrical performance but different base product numbers (74HC251 versus 74HC151). These parts are functionally interchangeable in 1 x 8:1 multiplexer applications.

Parts with Discontinued, Obsolete, or Last Time Buy status (CD74HC151MT, CD74HC251M96, NLV74HC251ADR2G) should be avoided for new designs due to supply constraints and limited availability.

Frequently Asked Questions (FAQ)

Q: Can I substitute CD74HC151M96E4 with CD74HC251M96 or CD74HC251MT?

A: Yes. Both CD74HC251M96 and CD74HC251MT maintain identical electrical specifications (1 x 8:1 multiplexer, 5.2mA output current, 2V ~ 6V supply, -55°C ~ 125°C operating range) and 16-SOIC package. The base product number difference (74HC251 versus 74HC151) does not affect functional equivalence in multiplexer applications.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape suitable for automated assembly equipment. Bulk packaging consists of loose components. Both formats contain identical components; packaging format selection depends on manufacturing process requirements and volume handling capabilities.

Q: Why does 74HC151D,653 have a narrower operating temperature range (-40°C ~ 125°C) than the original part (-55°C ~ 125°C)?

A: The Nexperia part is specified for -40°C minimum operating temperature rather than -55°C. This difference is acceptable for applications operating within standard industrial temperature ranges. Applications requiring extended low-temperature operation below -40°C should select alternatives maintaining the -55°C specification.

Q: Is 74HC151D-Q100,118 suitable for my application?

A: 74HC151D-Q100,118 is qualified to AEC-Q100 automotive standards and carries automotive grade designation. This part is suitable for automotive applications requiring qualification documentation. For non-automotive applications, standard-grade alternatives are appropriate.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant except CD74HC251M96 (Harris Corporation), which is RoHS non-compliant. For applications requiring RoHS compliance, select from the remaining alternatives.

Q: Can I use onsemi parts as direct replacements for Texas Instruments parts?

A: Yes. MC74HC151ADR2G and MC74HC251ADR2G (onsemi) maintain identical electrical specifications and 16-SOIC packaging. Cross-manufacturer substitution is valid when electrical parameters, package type, and pin configuration are identical.
