Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC4002MT is determined by strict equivalence across the following critical parameters:

• Logic Function: All substitutes must implement 2-channel, 4-input NOR gate logic
• Electrical Characteristics: Voltage supply range, quiescent current, output current, input logic levels, and propagation delay must match or exceed the original specification
• Package Compatibility: Surface mount 14-SOIC package with identical pin configuration and physical dimensions
• Base Product Series: All substitutes derive from the 74HC4002 base product number, ensuring functional interchangeability

Substitutes are grouped by product status and compliance certification. Parametric equivalents maintain identical electrical performance. Manufacturer-recommended alternatives provide equivalent functionality with variations in packaging format, temperature range, or compliance status.

Engineering Selection Recommendations

For RoHS3 Compliant Applications: Select 74HC4002D,652 (Nexperia) or 74HC4002D-Q100,118 (Nexperia). Both maintain ROHS3 compliance and identical electrical parameters. The 74HC4002D-Q100,118 variant includes AEC-Q100 automotive qualification and active product status, making it suitable for long-term procurement and automotive applications.

For Automotive Grade Requirements: The 74HC4002D-Q100,118 is the only substitute with AEC-Q100 qualification, meeting automotive industry standards for reliability and traceability.

For Extended Temperature Range (-55°C): The CD74HC4002M96 maintains the original -55°C to 125°C operating range, though it is RoHS non-compliant and obsolete. For compliant alternatives, the CD74HC4002MT and 74HC4002D-Q100,118 support -55°C operation in the original specification, while 74HC4002D,652 and 74HC4002D,653 are limited to -40°C minimum.

For Active Product Status: 74HC4002D,653 (NXP) and 74HC4002D-Q100,118 (Nexperia) are the only active products. The 74HC4002D-Q100,118 is preferred due to complete parameter documentation and automotive qualification.

For Tape & Reel Packaging: CD74HC4002MT (original) and 74HC4002D-Q100,118 are supplied in Tape & Reel format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can I substitute CD74HC4002MT with CD74HC4002M96?

A: Yes, from an electrical standpoint. Both parts are parametrically equivalent with identical voltage supply, current ratings, logic levels, and propagation delay. However, CD74HC4002M96 is RoHS non-compliant and obsolete. Use only if RoHS compliance is not required and long-term availability is not a concern.

Q: What is the difference between 14-SOIC and 14-SO packages?

A: Both designations refer to the same 14-pin small-outline integrated circuit package with 0.154" (3.90mm) width. The terms are used interchangeably by different manufacturers. Pin configuration and PCB footprint are identical.

Q: Is 74HC4002D-Q100,118 suitable for automotive applications?

A: Yes. The 74HC4002D-Q100,118 carries AEC-Q100 qualification, indicating compliance with automotive industry reliability and qualification standards. It is the only substitute with this certification.

Q: Why does 74HC4002D,653 have incomplete parameter documentation?

A: The 74HC4002D,653 from NXP Semiconductors is listed as active but lacks detailed electrical specifications in the provided data. For design applications requiring full parameter verification, use 74HC4002D-Q100,118 or 74HC4002D,652, which provide complete electrical and thermal specifications.

Q: Can I use 74HC4002D,652 in place of CD74HC4002MT if my design operates above -40°C?

A: Yes. The 74HC4002D,652 is fully equivalent for applications with operating temperatures between -40°C and 125°C. If your design requires operation below -40°C, the original CD74HC4002MT or CD74HC4002M96 are necessary.

Q: Which substitute has the best long-term availability?

A: The 74HC4002D-Q100,118 has active product status and automotive qualification, indicating ongoing manufacturing and distribution support. This makes it the most suitable choice for new designs requiring long-term component availability.
