74HC4002D,653 Equivalent & Substitute Parts

Part Overview

The 74HC4002D,653 is a NOR Gate IC with 2 channels and 4 inputs, manufactured by Nexperia USA Inc. in a 14-SOIC surface mount package. This logic component operates across a 2V to 6V supply voltage range and is designed for general-purpose digital logic applications requiring NOR gate functionality. The part is currently active in production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are necessary when the primary part becomes unavailable, when specific packaging or compliance requirements differ, or when alternative manufacturers' stock is preferred for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC4002D,653 is determined by the following critical parameters: logic type (NOR Gate), circuit count (2 channels), input count (4 inputs), supply voltage range (2V ~ 6V), output current capability (5.2mA), propagation delay (17ns @ 6V, 50pF), and package type (14-SOIC surface mount). All identified substitute parts maintain identical functional specifications across these core parameters. Variations exist in manufacturer identity, packaging format (Tube, Bulk, or Tape & Reel), product status (Active, Obsolete, or Discontinued), operating temperature range, and RoHS compliance status. These variations do not affect electrical interchangeability but may impact procurement, environmental compliance requirements, and long-term availability.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status & Full Compliance): The 74HC4002D,653 from Nexperia USA Inc. remains the preferred choice for new designs. It maintains active production status, ROHS3 compliance, and unlimited moisture sensitivity rating. The CD74HC4002MT from Texas Instruments is an acceptable alternative with identical electrical performance, ROHS3 compliance, and MSL 1 rating, though it is discontinued at DiGi Electronics.

Secondary Selection (Obsolete Status): The CD74HC4002M and CD74HC4002M96 from Harris Corporation are electrically equivalent but carry obsolete product status and RoHS non-compliance. These parts are suitable only for legacy system maintenance or applications where RoHS compliance is not required. The CD74HC4002M96 offers higher inventory availability (2900 pcs) in bulk packaging, while CD74HC4002M is available in tube packaging (1560 pcs).

Compliance Considerations: Applications subject to RoHS3 environmental regulations must use either the 74HC4002D,653 or CD74HC4002MT. The Harris Corporation variants (CD74HC4002M and CD74HC4002M96) do not meet RoHS3 requirements and are restricted to non-regulated applications.

Temperature Range Consideration: The Nexperia part operates from -40°C to 125°C, while all Harris and Texas Instruments substitutes extend the lower operating limit to -55°C. Selection should account for specific application temperature requirements.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically interchangeable with the 74HC4002D,653? A: Yes. All listed substitute parts maintain identical logic type (NOR Gate), circuit count (2 channels), input count (4 inputs), supply voltage range (2V ~ 6V), output current (5.2mA), propagation delay (17ns @ 6V, 50pF), and 14-SOIC package dimensions. Electrical interchangeability is confirmed across all parameters.

Q: What is the difference between CD74HC4002M, CD74HC4002M96, and CD74HC4002MT? A: These parts differ in manufacturer, packaging format, and compliance status. CD74HC4002M (Harris, Tube) and CD74HC4002M96 (Harris, Bulk) are obsolete and RoHS non-compliant. CD74HC4002MT (Texas Instruments, Tape & Reel) is discontinued at DiGi Electronics but maintains ROHS3 compliance and MSL 1 rating. All three are electrically identical to the primary part.

Q: Can I use CD74HC4002M or CD74HC4002M96 in a new design? A: These parts are not recommended for new designs due to obsolete status and RoHS non-compliance. They are suitable only for replacement in existing systems or applications where environmental regulations do not apply. For new designs, use the 74HC4002D,653 or CD74HC4002MT.

Q: Does operating temperature range affect substitution? A: The 74HC4002D,653 operates from -40°C to 125°C, while substitute parts from Harris and Texas Instruments extend to -55°C. If your application requires operation below -40°C, the substitute parts offer extended capability. For standard industrial applications (-40°C to 125°C), all parts are functionally equivalent.

Q: Are there packaging differences I should consider? A: Yes. The 74HC4002D,653 is supplied in Cut Tape (CT) & Digi-Reel format. CD74HC4002M uses Tube packaging, CD74HC4002M96 uses Bulk packaging, and CD74HC4002MT uses Tape & Reel (TR) packaging. All parts use the same 14-SOIC physical package, so PCB footprints are identical. Packaging choice affects handling, storage, and procurement logistics only.

Q: What is the significance of RoHS compliance in part selection? A: ROHS3 compliance is mandatory for products sold in the European Union and many other regulated markets. The 74HC4002D,653 and CD74HC4002MT are ROHS3 compliant. The Harris variants (CD74HC4002M and CD74HC4002M96) are RoHS non-compliant and cannot be used in regulated applications. Verify your market and regulatory requirements before selecting a substitute.
