CD4014BM Equivalent & Substitute Parts

Part Overview

The CD4014BM is a static shift register IC manufactured by Texas Instruments, part of the 4000B logic series. It functions as a parallel or serial to serial shift register with 1 element and 8 bits per element, housed in a 16-SOIC surface mount package. The CD4014BM is currently discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing design support and production requirements. Alternative parts maintain identical or compatible electrical and mechanical specifications while offering active product status or different packaging options.

Substitute Part Grouping Explanation

Substitution for the CD4014BM is determined by strict equivalence across the following critical parameters: logic type (shift register), output type (push-pull), number of elements (1), number of bits per element (8), function (parallel or serial to serial), package type (16-SOIC), and mounting type (surface mount). Substitute parts are grouped into three categories based on their relationship to the main part:

Direct Substitutes (Packaging Variant): CD4014BM96 maintains identical electrical specifications and base product number but differs only in packaging format (Tape & Reel vs. Tube).

Parametric Equivalents (Same Electrical Specs, Different Base Number): CD4021BM, CD4021BMG4, MC14014BDG, MC14014BDR2G, and MC14021BDG provide identical electrical performance and package specifications but represent different product lines within the 4000B series.

Manufacturer Recommended Equivalent: HEF4014BT,653 from Nexperia USA Inc. meets all functional and package requirements but operates within a narrower temperature range (-40°C ~ 85°C) and voltage range (3V ~ 15V) compared to the CD4014BM.

Engineering Selection Recommendations

For applications requiring immediate availability with active product status, CD4014BM96 (Texas Instruments, Tape & Reel) or MC14014BDR2G (onsemi, Tape & Reel) are direct functional equivalents. Both maintain the full voltage range (3V ~ 18V) and extended temperature range (-55°C ~ 125°C) of the original CD4014BM.

For designs operating within the narrower specifications of -40°C ~ 85°C and 3V ~ 15V, HEF4014BT,653 from Nexperia USA Inc. is the manufacturer-recommended equivalent and is currently in active production status.

onsemi's MC14014BDG and MC14021BDG offer active product status with full parameter compatibility to the CD4014BM and are available in Tube packaging. These parts are suitable for applications where the extended temperature and voltage ranges are required.

All substitute parts listed maintain ROHS3 compliance, MSL Level 1 (Unlimited), and identical 16-SOIC package dimensions, ensuring mechanical and environmental compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can CD4014BM96 be used as a direct replacement for CD4014BM? A: Yes. CD4014BM96 is a direct substitute differing only in packaging format (Tape & Reel vs. Tube). All electrical specifications, temperature range, voltage range, and functional parameters are identical.

Q: What is the difference between CD4014BM and CD4021BM? A: Both are 8-bit shift registers in the 4000B series with identical electrical specifications and 16-SOIC packaging. They differ in base product number and internal shift register configuration. Both are parametric equivalents for applications requiring 8-bit parallel or serial to serial shift register functionality.

Q: Is HEF4014BT,653 suitable for all CD4014BM applications? A: HEF4014BT,653 is suitable for applications operating within -40°C ~ 85°C and 3V ~ 15V. Applications requiring the extended temperature range (-55°C ~ 125°C) or full voltage range (3V ~ 18V) of the CD4014BM require alternative substitutes such as CD4014BM96 or MC14014BDG.

Q: What is the difference between Tube and Tape & Reel packaging? A: Tube packaging is used for manual handling and lower-volume applications. Tape & Reel packaging is designed for automated assembly processes and higher-volume production. Electrical and functional specifications remain identical; packaging choice depends on manufacturing process requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed (CD4014BM96, CD4021BM, CD4021BMG4, MC14014BDG, MC14014BDR2G, MC14021BDG, and HEF4014BT,653) are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute offers the best availability? A: MC14014BDR2G (onsemi, 2086 Pcs in stock) and HEF4014BT,653 (Nexperia, 2867 Pcs in stock) currently show the highest inventory levels among active products.
