CD4001BCN Equivalent & Substitute Parts

Part Overview

The CD4001BCN is a NOR Gate IC featuring 4 channels with 2 inputs per channel in a 14-MDIP package, manufactured by onsemi. This logic component operates across a wide supply voltage range of 3V to 15V and is designed for through-hole mounting applications. The part is currently classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD4001BCN is determined by the following critical parameters:

• Logic configuration: 4-channel NOR gate with 2 inputs per channel
• Electrical compatibility: Supply voltage range, quiescent current, output current, and input logic levels
• Propagation delay performance
• Package type: 14-DIP through-hole mounting
• Operating temperature range: -55°C to 125°C

The substitute parts CD4001BE (Texas Instruments) and CD4001UBE (Harris Corporation) maintain the same logic configuration and core electrical characteristics. Both are pin-compatible 14-DIP packages suitable for direct replacement in through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

CD4001BE (Texas Instruments) is the primary substitute for new designs and ongoing procurement. This part maintains full electrical compatibility with the CD4001BCN while offering active product status and ROHS3 compliance. The extended supply voltage range (3V ~ 18V) provides additional design margin. The slightly higher propagation delay (90ns versus 70ns) remains acceptable for most logic applications within the 4000B series timing specifications.

CD4001UBE (Harris Corporation) offers faster propagation delay (50ns) but carries obsolete product status and RoHS non-compliance, making it suitable only for legacy system maintenance where existing inventory is available.

Frequently Asked Questions (FAQ)

Q: Can CD4001BE directly replace CD4001BCN in existing designs? A: Yes. Both parts are pin-compatible 14-DIP packages with identical logic configuration (4-channel NOR gate, 2 inputs per channel). Electrical parameters including quiescent current, output current, and operating temperature range are equivalent. The CD4001BE supply voltage range extends to 18V, providing additional compatibility margin.

Q: What is the significance of the propagation delay difference between CD4001BCN (70ns) and CD4001BE (90ns)? A: The CD4001BE exhibits 20ns additional propagation delay at 15V with 50pF load. This difference is within typical 4000B series logic specifications and does not affect functional compatibility in standard digital logic applications. System timing analysis should verify acceptability for critical path applications.

Q: Why is CD4001UBE listed as a substitute if it is obsolete? A: CD4001UBE is included for reference in legacy system maintenance scenarios where existing inventory may be available. It offers superior propagation delay (50ns) but carries RoHS non-compliance and obsolete status, making it unsuitable for new designs. CD4001BE is the recommended choice for all new applications.

Q: Are there package or mounting differences between these parts? A: All three parts use identical 14-DIP (0.300", 7.62mm) through-hole packages. Direct socket substitution is possible without PCB modification.

Q: What compliance considerations apply to substitute selection? A: CD4001BE meets ROHS3 compliance requirements, making it suitable for applications with environmental or regulatory compliance mandates. CD4001BCN and CD4001UBE do not carry RoHS certification. REACH compliance is unaffected across all three parts.
