CD4015BME4 Equivalent & Substitute Parts

Part Overview

The CD4015BME4 is a dual 4-stage static shift register manufactured by Texas Instruments in the 4000B logic series. This component functions as a serial-to-parallel converter with 2 elements and 4 bits per element, housed in a 16-SOIC surface mount package. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts maintain functional equivalence while offering improved availability and product status options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4015BME4 is determined by strict parameter matching across the following criteria:

Core Functional Parameters:

• Logic Type: Shift Register
• Number of Elements: 2
• Number of Bits per Element: 4
• Function: Serial to Parallel
• Output Type: Push-Pull

Electrical Parameters:

• Voltage - Supply: 3V ~ 18V (or compatible subset)
• Operating Temperature: -55°C ~ 125°C (or compatible subset)

Physical Parameters:

• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain these core parameters. Variations in packaging format (Tube, Cut Tape, Tape & Reel) and product status do not affect functional substitution capability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Functional Replacement: MC14015BDR2G and MC14015BDG (onsemi) provide direct parametric equivalence with active product status, ensuring long-term availability and supply chain stability. Both maintain the full 3V ~ 18V supply voltage range and -55°C ~ 125°C operating temperature specification of the original CD4015BME4.

For Automotive Applications: NLV14015BDR2G (onsemi) is qualified to AEC-Q100 automotive standards and maintains full parameter compatibility. This part is suitable for designs requiring automotive-grade components with equivalent electrical and thermal specifications.

For Nexperia Supply Chain: HEF4015BT,653 (Nexperia USA Inc.) is an active product with ROHS3 compliance. Note that this part operates within a narrower supply voltage range (4.5V ~ 15.5V) and reduced operating temperature range (-40°C ~ 125°C) compared to the original specification. Selection requires verification that the application operates within these constraints.

For Texas Instruments Continuity: CD4015BM (Texas Instruments) maintains full parameter compatibility but carries Last Time Buy status, indicating limited future availability. This option is suitable only for immediate requirements where supply is confirmed.

Frequently Asked Questions (FAQ)

Q: Can MC14015BDR2G replace CD4015BME4 in all applications? A: Yes. MC14015BDR2G maintains identical functional parameters, supply voltage range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), and 16-SOIC package specification. The part is manufactured by onsemi and carries active product status.

Q: What is the difference between MC14015BDR2G and MC14015BDG? A: Both parts are manufactured by onsemi and maintain identical electrical and functional specifications. The difference is packaging format: MC14015BDR2G is supplied in Cut Tape (CT) & Digi-Reel format, while MC14015BDG is supplied in Tube format. Selection depends on assembly process requirements.

Q: Is HEF4015BT,653 a suitable substitute? A: HEF4015BT,653 is functionally equivalent but operates within a narrower specification window. The supply voltage range is 4.5V ~ 15.5V (versus 3V ~ 18V for the original) and operating temperature is -40°C ~ 125°C (versus -55°C ~ 125°C). This part is suitable only if the application operates within these narrower ranges.

Q: Why is NLV14015BDR2G marked as automotive grade? A: NLV14015BDR2G carries AEC-Q100 qualification, indicating it meets automotive industry reliability and quality standards. This part maintains full parameter compatibility with the original CD4015BME4 and is suitable for automotive and high-reliability applications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the environmental and regulatory status of the original CD4015BME4.

Q: What packaging options are available? A: Substitute parts are available in three packaging formats: Tube (CD4015BM, MC14015BDG), Cut Tape & Digi-Reel (MC14015BDR2G), and Tape & Reel (HEF4015BT,653, NLV14015BDR2G). Selection depends on assembly equipment and production volume requirements.
