Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HCT151M96G4 is determined by the following critical parameters: multiplexer circuit configuration (1 x 8:1), output current specifications (4mA high and low), single supply voltage range (4.5V ~ 5.5V), surface mount packaging in 16-SOIC form factor, and 74HCT logic series compatibility. All identified substitute parts maintain these core electrical and mechanical specifications, ensuring functional and physical interchangeability within the original design constraints.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing production, CD74HCT251M96 (Texas Instruments, Active status, ROHS3 Compliant) is the primary recommended substitute. This part maintains full electrical and mechanical compatibility with the original CD74HCT151M96G4 while offering active product status and current availability.

74HCT151D,653 (Nexperia USA Inc., Active status, ROHS3 Compliant) serves as a secondary alternative with identical electrical specifications. This part features a narrower operating temperature range (-40°C ~ 125°C versus -55°C ~ 125°C) and should be evaluated for applications requiring the full original temperature specification.

CD74HCT151M96 (Harris Corporation) is obsolete and RoHS non-compliant, making it unsuitable for new applications or designs requiring regulatory compliance.

CD74HCT251MT (Texas Instruments, ROHS3 Compliant) is discontinued at DiGi Electronics and should not be selected for new production due to supply constraints.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT251M96 directly replace CD74HCT151M96G4?

A: Yes. Both parts share identical electrical specifications (1 x 8:1 multiplexer, 4mA output current, 4.5V ~ 5.5V supply, 16-SOIC package) and are functionally interchangeable. CD74HCT251M96 is currently active and available.

Q: What is the difference between 16-SOIC and 16-SO packaging?

A: Both designations refer to 16-pin small-outline integrated circuit packages with 0.154" (3.90mm) width. These are mechanically and electrically compatible for PCB assembly and circuit operation.

Q: Does the operating temperature range difference between CD74HCT151M96G4 (-55°C ~ 125°C) and 74HCT151D,653 (-40°C ~ 125°C) affect substitution?

A: The narrower temperature range of 74HCT151D,653 is suitable for applications operating within -40°C to 125°C. Applications requiring operation below -40°C must use CD74HCT251M96 or the original part specification.

Q: Are all substitute parts ROHS3 compliant?

A: No. CD74HCT151M96 (Harris Corporation) is RoHS non-compliant. All other listed substitutes are ROHS3 compliant and suitable for applications with regulatory compliance requirements.

Q: What packaging options are available for substitute parts?

A: CD74HCT251M96 is supplied in Tape & Reel (TR) packaging. CD74HCT251MT is supplied in Cut Tape (CT) & Digi-Reel® packaging. 74HCT151D,653 is supplied in Tape & Reel (TR) packaging. All maintain the 16-SOIC form factor.
