CD4001BPW Equivalent & Substitute Parts

Part Overview

The CD4001BPW is a NOR Gate IC with 4 channels and 2 inputs per channel, manufactured by Texas Instruments in a 14-TSSOP surface mount package. This logic component operates across a wide supply voltage range of 3V to 18V and is designed for general-purpose digital logic applications. The CD4001BPW is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. Substitute parts maintain identical functional specifications and package compatibility while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4001BPW is determined by strict equivalence across the following critical parameters: logic type (NOR Gate), circuit count (4 channels), input count (2 inputs per channel), supply voltage range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), and physical package specification (14-TSSOP surface mount). All substitute parts listed maintain these core specifications, ensuring functional and mechanical compatibility. Differences in output current characteristics and propagation delay do not preclude substitution when these parameters remain within acceptable design margins for the target application.

Parameter Comparison

Engineering Selection Recommendations

CD4001BPWR is the direct equivalent from Texas Instruments, maintaining identical electrical characteristics and packaging. This part is actively produced and represents the primary substitute for the discontinued CD4001BPW, with the only difference being packaging format (Cut Tape & Digi-Reel versus Tube).

MC14001BDTR2G and NLV14001BDTR2G are onsemi alternatives that maintain full functional compatibility. Both parts deliver improved propagation delay performance (80ns versus 90ns) and higher output current capability (8.8mA versus 3.4mA). These characteristics provide enhanced performance margins in applications requiring faster switching or higher drive capability. Both onsemi parts are actively produced and ROHS3 compliant.

All substitute parts maintain identical supply voltage range, quiescent current, operating temperature range, and 14-TSSOP package specification. Selection among these alternatives should be based on availability, packaging preference, and application-specific performance requirements.

Frequently Asked Questions (FAQ)

Q: Can CD4001BPWR directly replace CD4001BPW in existing designs? A: Yes. CD4001BPWR is functionally and mechanically equivalent to CD4001BPW. The difference is packaging format: CD4001BPW is supplied in Tube packaging, while CD4001BPWR is supplied in Cut Tape & Digi-Reel format. Both use the 14-TSSOP package and are pin-compatible.

Q: What are the differences between Texas Instruments and onsemi versions? A: MC14001BDTR2G and NLV14001BDTR2G from onsemi provide faster propagation delay (80ns versus 90ns at 15V, 50pF) and higher output current (8.8mA versus 3.4mA). These are performance improvements that do not affect compatibility. All parts maintain identical logic function, supply voltage range, and operating temperature specifications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. CD4001BPWR, MC14001BDTR2G, and NLV14001BDTR2G are all ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original CD4001BPW specification.

Q: Does the higher output current of onsemi parts affect circuit design? A: No. Higher output current (8.8mA versus 3.4mA) represents improved drive capability and does not require circuit modifications. Applications designed for the original 3.4mA specification will operate correctly with the higher-current onsemi alternatives.

Q: What is the difference between MC14001BDTR2G and NLV14001BDTR2G? A: Both parts are onsemi products with identical electrical specifications and performance characteristics. The difference is in the base product number designation (MC14001 versus NLV14001). Both are actively produced and suitable for substitution.
