Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4001BMT is determined by the following critical parameters:

Functional Equivalence Requirements:

• Logic Type: NOR Gate
• Number of Circuits: 4
• Number of Inputs: 2
• Series: 4000B

Electrical Compatibility Parameters:

• Voltage - Supply: 3V ~ 18V (minimum requirement)
• Current - Quiescent (Max): ≤ 1 µA
• Current - Output High, Low: ≤ 3.4mA per channel
• Input Logic Level - Low: 1.5V ~ 4V
• Input Logic Level - High: 4.6V ~ 11V
• Max Propagation Delay @ 15V, 50pF: ≤ 90ns

Physical Compatibility:

• Mounting Type: Surface Mount
• Package / Case: 14-SOIC (0.154", 3.90mm Width)

Substitute parts must meet all functional equivalence requirements and maintain electrical compatibility within the specified parameter ranges. Parts with higher output current capability, faster propagation delay, or wider supply voltage ranges are acceptable as they provide equal or superior performance. Parts with narrower operating temperature ranges, reduced supply voltage ranges, or different packaging dimensions are not direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Tier 1 - Direct Parametric Equivalents (Recommended for Replacement):

CD4001BM96 (Harris Corporation) provides identical electrical specifications to the CD4001BMT with matching supply voltage range (3V ~ 18V), quiescent current (1 µA), output current (3.4mA), and propagation delay (90ns). This part maintains full compatibility with the original design and is currently in active production status with 35,300 units available.

Tier 2 - Enhanced Performance Substitutes (Compatible with Design Verification):

MC14001BDR2G and MC14001BDG (onsemi) offer superior output current capability (8.8mA vs 3.4mA) and faster propagation delay (80ns vs 90ns) while maintaining the same supply voltage range and operating temperature span. These parts are suitable for applications where increased drive capability is beneficial. MC14001UBDG provides asymmetrical output current (4.6mA high, 8.8mA low) with the same performance advantages.

Tier 3 - Reduced Specification Substitutes (Limited Compatibility):

HEC4001BT,112, HEC4001BT,118, HEF4001BT,653, and HEF4001BT-Q100J (NXP and Nexperia) feature reduced supply voltage range (3V ~ 15V vs 3V ~ 18V) and narrower operating temperature range (-40°C ~ 125°C vs -55°C ~ 125°C). These parts are suitable only for applications operating within their specified voltage and temperature limits. HEF4001BT-Q100J includes AEC-Q100 automotive qualification for applications requiring automotive-grade components.

Not Recommended:

BU4001BF-E2 (Rohm Semiconductor) has a narrower operating temperature range (-40°C ~ 85°C), reduced supply voltage range (3V ~ 16V), and different package dimensions (0.173" vs 0.154" width). This part is marked "Not For New Designs" and is not suitable for replacement applications.

HEF4001BT,652 (Nexperia) is obsolete and should not be selected for new designs or ongoing production.

Frequently Asked Questions (FAQ)

Q: Can I use MC14001BDR2G as a direct replacement for CD4001BMT?

A: Yes. MC14001BDR2G is functionally equivalent with identical logic configuration (4-channel 2-input NOR gate) and meets all electrical compatibility requirements. It provides superior output current (8.8mA vs 3.4mA) and faster propagation delay (80ns vs 90ns), making it a compatible substitute. The part is available in 14-SOIC packaging with the same 0.154" width and operates across the full -55°C to 125°C temperature range.

Q: What is the difference between MC14001BDG and MC14001BDR2G?

A: Both parts are electrically identical with the same specifications. The primary difference is packaging: MC14001BDG is supplied in Tube packaging while MC14001BDR2G is supplied in Tape & Reel (TR) format. Select based on your assembly process requirements.

Q: Why does BU4001BF-E2 have a different package width (0.173" vs 0.154")?

A: BU4001BF-E2 uses a 14-SOP package variant with 0.173" width, which differs from the standard 14-SOIC package of the CD4001BMT. This dimensional difference may cause compatibility issues with PCB footprints designed for the original 0.154" width package. This part is not recommended for replacement.

Q: Can I use HEF4001BT-Q100J in applications requiring -55°C operation?

A: No. HEF4001BT-Q100J has a minimum operating temperature of -40°C, which does not meet the -55°C requirement of the original CD4001BMT. This part is suitable only for applications operating within -40°C to 125°C range. For full temperature range compatibility, select CD4001BM96 or MC14001 series parts.

Q: What is the significance of the supply voltage range difference (3V ~ 18V vs 3V ~ 15V)?

A: The CD4001BMT supports operation up to 18V supply, while HEC4001BT and HEF4001BT series are limited to 15V maximum. If your application requires supply voltages between 15V and 18V, you must use CD4001BM96 or MC14001 series parts. For applications operating at 15V or below, either group is acceptable.

Q: Is HEF4001BT-Q100J suitable for automotive applications?

A: Yes. HEF4001BT-Q100J carries AEC-Q100 automotive qualification, making it suitable for automotive-grade applications. However, it has a reduced operating temperature range (-40°C ~ 125°C) and supply voltage range (3V ~ 15V) compared to the original CD4001BMT. Verify these specifications meet your automotive application requirements before selection.

Q: What packaging options are available for CD4001 NOR gate substitutes?

A: Available packaging formats include Cut Tape (CT) & Digi-Reel for individual component handling, Tape & Reel (TR) for automated assembly, and Tube for manual assembly. Select based on your production volume and assembly process. All recommended substitutes maintain the 14-SOIC (0.154", 3.90mm width) package footprint except BU4001BF-E2.
