Substitute Part Grouping Explanation

Substitution of the 74HC4015N,652 is determined by strict equivalence across the following critical parameters:

• Base product number (74HC4015 series)
• Logic type and function (dual 4-bit shift register, serial-to-parallel conversion)
• Number of elements (2) and bits per element (4)
• Output type (Push-Pull)
• Package type (16-DIP through-hole)
• Supply voltage range (2V ~ 6V)
• Operating temperature range compatibility

The CD74HC4015E qualifies as a direct substitute based on identical functional architecture, pinout, and electrical specifications. Variations in manufacturing source, product status, and compliance certifications do not affect functional interchangeability within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The CD74HC4015E serves as a functional equivalent to the 74HC4015N,652 for applications requiring dual 4-bit shift register functionality in 16-DIP through-hole packages. Both components are classified as obsolete products.

Selection between these parts should account for the following compliance considerations:

• The 74HC4015N,652 maintains ROHS3 compliance, suitable for applications subject to RoHS regulatory requirements.
• The CD74HC4015E is RoHS non-compliant, appropriate for legacy systems or applications without RoHS mandates.
• The CD74HC4015E supports an extended lower operating temperature limit of -55°C compared to the 74HC4015N,652 at -40°C, providing broader thermal operating range for cold-environment applications.

Both components share identical electrical specifications, pinout configuration, and mechanical package dimensions, ensuring direct socket compatibility in 16-DIP through-hole circuit board layouts.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4015E replace the 74HC4015N,652 in existing designs?

A: Yes. Both components are functionally equivalent shift registers with identical pin configurations, electrical characteristics, and 16-DIP package dimensions. Direct substitution is possible without circuit modification.

Q: What is the difference in operating temperature range?

A: The CD74HC4015E operates from -55°C to 125°C, while the 74HC4015N,652 operates from -40°C to 125°C. The CD74HC4015E provides extended low-temperature capability. Both support the same upper temperature limit.

Q: Are there RoHS compliance differences?

A: Yes. The 74HC4015N,652 is ROHS3 compliant, while the CD74HC4015E is RoHS non-compliant. Component selection should align with applicable regulatory and procurement requirements.

Q: Do both parts use the same package?

A: Yes. Both components use 16-DIP (0.300", 7.62mm) through-hole packages with identical pinout and mechanical dimensions.

Q: Why are both parts classified as obsolete?

A: Both the 74HC4015N,652 and CD74HC4015E are obsolete products. Obsolescence indicates discontinued manufacturing by the original suppliers. Availability is limited to existing inventory from authorized distributors.
