Substitute Part Grouping Explanation

Substitution for the CD4030BPW is determined by matching the following critical parameters:

Logic Type: XOR (Exclusive OR) with 4 channels and 2 inputs per channel
Electrical Specifications: Supply voltage range 3V ~ 18V, quiescent current 1 µA maximum, output current 3.4mA, propagation delay 100ns @ 15V with 50pF load
Input Logic Levels: Low 1.5V ~ 4V, High 4.6V ~ 11V
Operating Temperature Range: -55°C ~ 125°C
Package: 14-TSSOP surface mount configuration
Compliance: ROHS3 compliant, MSL Level 1

The identified substitutes maintain identical electrical and functional specifications while differing in packaging format (Tube vs. Tape & Reel) and product status.

Engineering Selection Recommendations

CD4030BPWR is the primary recommended substitute for CD4030BPW. Both parts are manufactured by Texas Instruments with identical electrical and functional specifications. The CD4030BPWR maintains Active product status, ensuring long-term availability and supply chain stability. The only difference is packaging format: CD4030BPWR is supplied in Tape & Reel format, which is standard for high-volume production environments, while CD4030BPW is supplied in Tube format. Both are ROHS3 compliant with MSL Level 1 rating.

CD4070BPW is a parametric equivalent with identical electrical specifications and the same 14-TSSOP package format as the main part. However, CD4070BPW is listed as Discontinued at DiGi Electronics, which limits its suitability for new designs or long-term production requirements. This part should be considered only when packaging format (Tube) is a specific requirement and supply availability can be confirmed through alternative channels.

Frequently Asked Questions (FAQ)

Q: Can CD4030BPWR be used as a direct replacement for CD4030BPW?

A: Yes. Both parts are electrically and functionally identical. The difference is packaging format: CD4030BPWR uses Tape & Reel packaging while CD4030BPW uses Tube packaging. Both are suitable for surface mount assembly with identical 14-TSSOP package dimensions.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging is used for lower-volume orders and manual handling, while Tape & Reel packaging is optimized for automated pick-and-place assembly equipment. Both formats contain the same component with identical electrical performance.

Q: Why is CD4030BPW marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer is discontinuing this specific part number variant. CD4030BPWR (Active status) is the recommended alternative for continued production.

Q: Is CD4070BPW a suitable alternative?

A: CD4070BPW has identical electrical specifications and package type (Tube). However, it is discontinued at DiGi Electronics, which may limit availability. Verify supply chain access before selecting this part for new designs.

Q: Are all three parts ROHS3 compliant?

A: Yes. CD4030BPW, CD4030BPWR, and CD4070BPW are all ROHS3 compliant with MSL Level 1 rating, suitable for standard PCB assembly processes.

Q: What are the key electrical parameters that make these parts interchangeable?

A: All three parts share identical specifications: 4-channel XOR logic, 2 inputs per channel, 3V ~ 18V supply voltage, 1 µA quiescent current, 3.4mA output current, and 100ns propagation delay at 15V with 50pF load. Operating temperature range is -55°C ~ 125°C for all parts.
