CD4001BE-NG Equivalent & Substitute Parts

Part Overview

The CD4001BE-NG is a NOR Gate IC featuring 4 channels with 2 inputs per channel, manufactured by Texas Instruments in a 14-DIP through-hole package. This device operates across a wide supply voltage range of 3V to 18V and is classified as obsolete. Due to its obsolete status and limited current inventory availability (813 pieces), identifying active equivalent parts is essential for ongoing design support and production continuity. The CD4001BPWR serves as the manufacturer-recommended substitute, offering identical functional specifications with improved availability and modern packaging options.

Substitute Part Grouping Explanation

Substitution between CD4001BE-NG and CD4001BPWR is valid based on the following criteria:

Functional Equivalence: Both devices implement identical NOR gate logic with 4 circuits and 2 inputs per channel. The logic truth tables, input/output voltage thresholds, and propagation delay characteristics are identical.

Electrical Compatibility: Both parts operate within the same supply voltage range (3V ~ 18V), accept the same input logic levels (Low: 1.5V ~ 4V; High: 3.5V ~ 11V), and deliver equivalent propagation delay performance (90ns @ 15V, 50pF).

Regulatory Compliance: Both devices meet ROHS3 compliance requirements and share the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Key Differentiators: The primary differences are packaging format (14-DIP through-hole versus 14-TSSOP surface mount), quiescent current (5 µA versus 1 µA), output current capability (6.8mA versus 3.4mA), and product status (obsolete versus active).

Engineering Selection Recommendations

For Through-Hole PCB Designs: The CD4001BE-NG remains the appropriate choice if existing board layouts utilize through-hole mounting and component availability is confirmed. However, given obsolete status, long-term supply cannot be guaranteed.

For New Designs or Redesigns: The CD4001BPWR is the manufacturer-recommended substitute and should be selected for all new development. This device carries active product status, ensuring sustained availability and manufacturing support. The surface-mount 14-TSSOP package enables smaller board footprints and improved manufacturing efficiency.

For Existing Production: Transition planning from CD4001BE-NG to CD4001BPWR is recommended. Both devices deliver identical functional performance and meet current regulatory requirements (ROHS3 compliance). The substitution requires PCB layout modification to accommodate surface-mount packaging but introduces no functional risk.

Compliance Verification: Both parts satisfy ROHS3 compliance and share identical trade classification codes, confirming regulatory equivalence for procurement and supply chain purposes.

Frequently Asked Questions (FAQ)

Q: Can CD4001BPWR directly replace CD4001BE-NG in existing circuits?

A: Functionally, yes. Both devices implement identical NOR gate logic with matching electrical specifications. However, physical replacement requires PCB layout modification because CD4001BE-NG uses through-hole 14-DIP packaging while CD4001BPWR uses surface-mount 14-TSSOP packaging. Schematic-level substitution is valid; board-level implementation requires redesign.

Q: What are the key electrical differences between these parts?

A: Quiescent current and output drive capability differ. CD4001BPWR consumes 1 µA quiescent current versus 5 µA for CD4001BE-NG, and provides 3.4mA output current versus 6.8mA. These differences reflect modern process technology in the active part. Both specifications remain within acceptable ranges for standard CMOS logic applications.

Q: Why is CD4001BE-NG classified as obsolete?

A: Through-hole DIP packaging has been superseded by surface-mount technologies in modern manufacturing. Texas Instruments has transitioned the 4001 NOR gate family to active production in surface-mount packages (14-TSSOP) while discontinuing through-hole variants.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. Regulatory and trade compliance is equivalent.

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

A: CD4001BE-NG is supplied in 14-DIP through-hole format. CD4001BPWR is supplied in 14-TSSOP surface-mount format with Cut Tape (CT) and Digi-Reel® packaging options. Both represent the same base product (CD4001) in different package configurations.

Q: Is the CD4001BPWR suitable for high-temperature applications?

A: Yes. CD4001BPWR maintains the full operating temperature range of -55°C to 125°C, identical to CD4001BE-NG, supporting extended temperature applications.
