CD4014BPW Equivalent & Substitute Parts

Part Overview

The CD4014BPW is a static shift register IC manufactured by Texas Instruments, part of the 4000B logic series. This 8-stage, 1-element shift register operates across a wide supply voltage range of 3V to 18V and supports both parallel and serial input configurations with serial output. The device is housed in a 16-TSSOP surface mount package.

The CD4014BPW carries a Last Time Buy status, indicating that Texas Instruments has discontinued production. This necessitates identifying equivalent substitute components that maintain identical electrical and mechanical specifications for continued system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the CD4014BPW is determined by strict equivalence across the following critical parameters:

• Logic Type: Shift Register
• Number of Elements: 1
• Number of Bits per Element: 8
• Function: Parallel or Serial to Serial
• Output Type: Push-Pull
• Voltage - Supply: 3V ~ 18V
• Operating Temperature: -55°C ~ 125°C
• Package / Case: 16-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitutes are categorized by packaging format and product status. The CD4014BPWR represents the direct equivalent in Tape & Reel packaging with Active product status. The CD4021BPW provides parametric equivalence with identical electrical specifications but differs in base product number and current availability status.

Engineering Selection Recommendations

For new designs and ongoing production requiring the CD4014BPW functionality, the CD4014BPWR is the primary substitute. This part maintains identical electrical and mechanical specifications while carrying Active product status from Texas Instruments, ensuring continued availability and supply chain stability. The Tape & Reel packaging format is standard for high-volume manufacturing operations.

The CD4021BPW provides parametric equivalence across all critical electrical and mechanical parameters. However, this part is listed as Discontinued at DiGi Electronics, which may impact long-term availability. Selection of this substitute should be evaluated against supply chain requirements and inventory planning.

Both substitutes maintain ROHS3 compliance and MSL Level 1 ratings, ensuring compatibility with modern manufacturing processes and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can CD4014BPWR be used as a direct replacement for CD4014BPW in existing designs?

A: Yes. The CD4014BPWR is electrically and mechanically identical to the CD4014BPW. The only difference is the packaging format: CD4014BPWR uses Tape & Reel (TR) packaging while CD4014BPW uses Tube packaging. Both are 16-TSSOP surface mount packages with identical pin configurations and electrical characteristics.

Q: What is the difference between CD4014BPW and CD4021BPW?

A: Both parts are 8-bit shift registers with identical electrical specifications, supply voltage range, operating temperature, and package type. The primary difference is the base product number designation (CD4014 versus CD4021), which reflects different internal logic configurations. Both are parametrically equivalent for the specified shift register function.

Q: Why is CD4014BPW marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has ceased production of this part number. Existing inventory may be available through authorized distributors, but no new production runs are planned. The CD4014BPWR with Active status is the recommended path forward for continued supply.

Q: Are there any compliance or certification differences between these substitutes?

A: No. All three parts (CD4014BPW, CD4014BPWR, and CD4021BPW) maintain identical RoHS3 compliance, REACH Unaffected status, and MSL Level 1 ratings. They are suitable for equivalent applications in regulated manufacturing environments.

Q: What packaging considerations should be evaluated when selecting between these parts?

A: CD4014BPW and CD4021BPW are supplied in Tube packaging, suitable for lower-volume applications and manual assembly. CD4014BPWR is supplied in Tape & Reel format, optimized for automated pick-and-place assembly in high-volume production. Select based on your manufacturing process and volume requirements.
