CD4015BM Equivalent & Substitute Parts

Part Overview

The CD4015BM is a dual 4-stage shift register logic IC manufactured by Texas Instruments in 16-SOIC surface mount packaging. This device functions as a serial-to-parallel converter with push-pull output configuration, operating across a wide supply voltage range of 3V to 18V and temperature range of -55°C to 125°C. The CD4015BM is classified as Last Time Buy, indicating end-of-life status. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain component availability for production and field replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4015BM is determined by strict equivalence across the following critical parameters: logic type (shift register), functional configuration (dual 4-bit serial-to-parallel), output type (push-pull), package format (16-SOIC surface mount), and electrical operating ranges (supply voltage and temperature). All substitute parts listed maintain identical or compatible specifications within these core parameters, ensuring functional and mechanical interchangeability. Packaging format variations (Cut Tape, Tape & Reel, Tube) do not affect electrical compatibility but may impact procurement and handling requirements.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status except the CD4015BM, which is Last Time Buy. For new designs and ongoing production, CD4015BM96, MC14015BDR2G, MC14015BDG, HEF4015BT,653, and NLV14015BDR2G are functionally equivalent alternatives. All parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

The NLV14015BDR2G variant includes AEC-Q100 automotive qualification, making it suitable for applications requiring automotive-grade components. The HEF4015BT,653 operates within a narrower supply voltage range (4.5V to 15.5V) and temperature range (-40°C to 125°C) compared to other options, requiring verification of application compatibility before selection.

For standard industrial and commercial applications, CD4015BM96 (Texas Instruments, active status) provides direct manufacturer continuity. For onsemi-based designs, MC14015BDR2G and MC14015BDG offer equivalent functionality with different packaging formats. Packaging selection (Cut Tape, Tape & Reel, or Tube) should align with procurement and assembly requirements without affecting electrical performance.

Frequently Asked Questions (FAQ)

Q: Can CD4015BM96 directly replace CD4015BM in existing designs? A: Yes. CD4015BM96 is manufactured by the same supplier (Texas Instruments) and maintains identical electrical specifications, package format, and pin configuration. The primary difference is product status (active versus last time buy) and packaging format (Cut Tape & Digi-Reel versus Tube).

Q: What is the difference between MC14015BDR2G and MC14015BDG? A: Both are onsemi MC14015 variants with identical electrical specifications and 16-SOIC packaging. The primary difference is packaging format: MC14015BDR2G is supplied in Cut Tape & Digi-Reel format, while MC14015BDG is supplied in Tube format. Electrical performance and pin configuration are equivalent.

Q: Is HEF4015BT,653 compatible with applications requiring -55°C operation? A: No. HEF4015BT,653 operates from -40°C to 125°C, which does not meet the lower temperature requirement of -55°C specified for CD4015BM. Applications requiring -55°C minimum operation must use CD4015BM96, MC14015BDR2G, MC14015BDG, or NLV14015BDR2G.

Q: Does NLV14015BDR2G automotive qualification affect its use in non-automotive applications? A: No. AEC-Q100 qualification indicates enhanced reliability testing and quality assurance. NLV14015BDR2G is fully compatible with standard industrial and commercial applications and offers equivalent electrical performance to non-automotive variants.

Q: Are all substitute parts available in 16-SOIC surface mount packaging? A: Yes. All listed substitute parts use 16-SOIC (0.154", 3.90mm width) surface mount packaging, ensuring mechanical and electrical compatibility with existing PCB designs and assembly processes.

Q: What supply voltage range applies when selecting a substitute? A: CD4015BM, CD4015BM96, MC14015BDR2G, MC14015BDG, and NLV14015BDR2G operate across 3V to 18V. HEF4015BT,653 operates across 4.5V to 15.5V. Applications requiring operation below 4.5V must exclude HEF4015BT,653 from consideration.
