Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC4015D,652 is determined by strict equivalence across the following critical parameters:

• Logic type and function (Shift Register, Serial to Parallel conversion)
• Number of elements (2) and bits per element (4)
• Output type (Push-Pull)
• Supply voltage range (2V ~ 6V minimum compatibility)
• Package type and physical dimensions (16-SOIC, 0.154" width)
• Mounting technology (Surface Mount)
• Compliance certifications (ROHS3, REACH Unaffected)

The CD74HC4015M from Texas Instruments meets all these criteria and maintains full functional and electrical compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

The CD74HC4015M is a direct functional equivalent to the 74HC4015D,652. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The CD74HC4015M offers the advantage of active product status, ensuring continued availability and supply chain stability. The extended operating temperature range of the CD74HC4015M (-55°C to 125°C versus -40°C to 125°C) provides additional thermal margin for applications requiring lower temperature operation. Both parts share identical electrical specifications, package dimensions, and pin configurations, enabling direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4015M be used as a direct replacement for the 74HC4015D,652?

A: Yes. Both parts are functionally equivalent dual static shift registers with identical logic type, element count, bit configuration, output type, supply voltage range, package type, and physical dimensions. Pin-for-pin substitution is supported.

Q: What is the significance of the product status difference?

A: The 74HC4015D,652 is obsolete, meaning NXP has discontinued production and support. The CD74HC4015M is active, indicating Texas Instruments continues manufacturing and supporting this part. Active status ensures long-term availability and supply reliability.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant and REACH unaffected. They meet identical regulatory requirements for environmental and hazardous substance restrictions.

Q: Does the extended temperature range of the CD74HC4015M affect compatibility?

A: No. The CD74HC4015M's extended lower temperature limit (-55°C versus -40°C) is a superset of the original part's range. Applications operating within the original -40°C to 125°C range will function identically on both parts.

Q: Are the packages physically identical?

A: Yes. Both parts use 16-SOIC packaging with 0.154" (3.90mm) width. PCB footprints and assembly processes are identical.
