Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4002BMG4 is determined by strict equivalence across the following critical parameters:

• Logic function: NOR Gate with 2 channels and 4 inputs
• Package compatibility: 14-SOIC surface mount form factor
• Electrical performance: Supply voltage range, quiescent current, output current, propagation delay, and input logic levels
• Environmental compliance: RoHS3 compliance and operating temperature range
• Moisture sensitivity: MSL Level 1 (Unlimited)

Substitute parts are grouped into two categories based on manufacturer and packaging configuration:

Category 1: Texas Instruments (Same Base Product)

• CD4002BM96: Tape & Reel packaging variant, Active status
• CD4002BM: Tube packaging variant, Last Time Buy status

Category 2: Alternative Manufacturers (NXP/Nexperia)

• HEC4002BT,112 and HEC4002BT,118: NXP USA Inc., Active status
• HEF4002BT,652: Nexperia USA Inc., Obsolete status

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for New Designs)

CD4002BM96 is the preferred substitute for the CD4002BMG4. Both parts are manufactured by Texas Instruments with identical electrical specifications and operating temperature range (-55°C ~ 125°C). The CD4002BM96 is in Active product status with higher inventory availability (2610 Pcs) compared to the CD4002BMG4 (Last Time Buy status). The only difference is packaging configuration: CD4002BM96 is supplied in Tape & Reel format, while CD4002BMG4 is supplied in Tube format. Both are ROHS3 compliant with MSL Level 1 rating.

CD4002BM is an alternative Texas Instruments substitute with identical electrical and thermal specifications. However, it shares Last Time Buy status with the original part, limiting its suitability for long-term supply chain planning.

Secondary Substitutes (Alternative Manufacturers)

HEC4002BT,112 and HEC4002BT,118 (NXP USA Inc.) are functionally equivalent alternatives with the following considerations:

• Supply voltage range is reduced to 3V ~ 15V (versus 3V ~ 18V for CD4002BMG4)
• Propagation delay is improved to 40ns @ 15V, 50pF (versus 90ns for CD4002BMG4)
• Operating temperature range remains -55°C ~ 125°C
• Both parts are in Active product status with good inventory availability
• ROHS3 compliant with MSL Level 1 rating

HEF4002BT,652 (Nexperia USA Inc.) is not recommended for new designs due to Obsolete product status. Additionally, this part exhibits higher quiescent current (4 µA versus 1 µA) and reduced output current (3mA versus 3.4mA), along with a narrower operating temperature range (-40°C ~ 85°C).

Frequently Asked Questions (FAQ)

Q: Can CD4002BM96 be used as a direct replacement for CD4002BMG4?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, operating temperature range, and 14-SOIC package form factor. The difference is packaging configuration: CD4002BM96 uses Tape & Reel format while CD4002BMG4 uses Tube format. Both are ROHS3 compliant and suitable for surface mount assembly.

Q: What is the difference between the Texas Instruments and NXP substitutes?

A: Texas Instruments substitutes (CD4002BM96, CD4002BM) maintain the full 3V ~ 18V supply voltage range and 90ns propagation delay. NXP substitutes (HEC4002BT,112, HEC4002BT,118) reduce the supply voltage range to 3V ~ 15V but offer improved propagation delay of 40ns. Both maintain the same operating temperature range and package form factor.

Q: Is the HEF4002BT,652 suitable for new designs?

A: No. This part is designated Obsolete and exhibits degraded electrical characteristics compared to the CD4002BMG4, including higher quiescent current (4 µA versus 1 µA), reduced output current (3mA versus 3.4mA), and a narrower operating temperature range (-40°C ~ 85°C versus -55°C ~ 125°C).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (CD4002BM96, CD4002BM, HEC4002BT,112, HEC4002BT,118, and HEF4002BT,652) are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What packaging options are available for substitutes?

A: CD4002BM96 is supplied in Tape & Reel (TR) format. CD4002BM is supplied in Tube format. NXP and Nexperia substitutes (HEC4002BT,112, HEC4002BT,118, HEF4002BT,652) are supplied in standard packaging configurations. All maintain the 14-SOIC (0.154", 3.90mm Width) surface mount package form factor.

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

A: CD4002BM96 is recommended for long-term availability due to its Active product status and higher inventory level (2610 Pcs). The NXP alternatives (HEC4002BT,112, HEC4002BT,118) are also in Active status with comparable inventory availability (1005 Pcs and 1167 Pcs respectively).
