Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC4002PW,112 is determined by strict equivalence across the following critical parameters:

• Logic Function: NOR Gate with identical 2-channel, 4-input configuration
• Electrical Specifications: Matching voltage supply range (2V ~ 6V), quiescent current (2 µA max), output current (5.2mA), input logic levels, and propagation delay (17ns @ 6V, 50pF)
• Package Compatibility: 14-TSSOP surface mount package with identical physical dimensions
• Environmental & Compliance: ROHS3 compliance, MSL Level 1, and REACH unaffected status

All substitute parts listed maintain these core parameters, ensuring functional and mechanical interchangeability within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: CD74HC4002PWR (Texas Instruments)

The CD74HC4002PWR is the preferred substitute for the 74HC4002PW,112. This part maintains full electrical and mechanical equivalence while offering Active product status, ensuring long-term availability and supply chain stability. The extended operating temperature range (-55°C ~ 125°C) provides additional margin for demanding applications. Tape & Reel packaging supports high-volume production requirements.

Secondary Options: CD74HC4002PW and CD74HC4002PWT (Texas Instruments)

Both CD74HC4002PW and CD74HC4002PWT provide functional equivalence with identical electrical specifications and package compatibility. These parts are classified as Discontinued at DiGi Electronics, indicating limited future availability. Selection between these options depends on packaging requirements: CD74HC4002PW is supplied in Tube packaging, while CD74HC4002PWT packaging is unspecified. These options are suitable for applications where immediate availability is prioritized over long-term supply assurance.

Compliance & Certification

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, ensuring regulatory alignment with the original 74HC4002PW,112 specification.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4002PWR directly replace 74HC4002PW,112 in existing designs?

A: Yes. The CD74HC4002PWR maintains identical electrical specifications, logic function, input/output characteristics, and 14-TSSOP package dimensions. No circuit modifications are required for direct substitution.

Q: What is the difference between CD74HC4002PW, CD74HC4002PWR, and CD74HC4002PWT?

A: All three parts are functionally equivalent NOR Gate ICs with identical electrical performance. The differences are packaging format (Tube, Tape & Reel, and unspecified respectively) and product status. CD74HC4002PWR is Active; the other two are Discontinued at DiGi Electronics.

Q: Why does CD74HC4002PWR have an extended operating temperature range (-55°C ~ 125°C) compared to the original part (-40°C ~ 125°C)?

A: The extended lower temperature limit represents a broader operational envelope offered by Texas Instruments. This does not affect compatibility; designs operating within the original -40°C ~ 125°C range remain fully functional.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL Level 1 rating, matching the original 74HC4002PW,112 specification.

Q: Which substitute part should be selected for new designs?

A: CD74HC4002PWR is recommended for new designs due to its Active product status, ensuring sustained availability and supply chain continuity. This part is suitable for both prototype and production-volume applications.

Q: Is the 14-TSSOP package identical across all parts?

A: Yes. All parts use the 14-TSSOP package with identical physical dimensions (0.173", 4.40mm Width), ensuring mechanical interchangeability on PCBs designed for the original 74HC4002PW,112.
