CD4071BPW Equivalent & Substitute Parts

Part Overview

The CD4071BPW is a 4-channel OR gate logic IC manufactured by Texas Instruments in 14-TSSOP surface mount packaging. This component operates across a wide supply voltage range of 3V to 18V and is compliant with ROHS3 standards. The part is currently in Last Time Buy status, indicating limited availability. Equivalent and substitute parts are necessary to ensure design continuity, maintain supply chain flexibility, and accommodate different packaging or manufacturer preferences while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4071BPW is determined by the following critical parameters:

• Logic function: 4-channel OR gate with 2 inputs per channel
• Supply voltage range: 3V to 18V
• Package type: 14-TSSOP surface mount
• Operating temperature range: -55°C to 125°C
• RoHS3 compliance

All substitute parts listed maintain identical logic configuration, voltage specifications, temperature range, and package form factor. Variations in output current and propagation delay remain within acceptable tolerances for OR gate applications and do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

CD4071BPWR is the primary substitute for CD4071BPW, both manufactured by Texas Instruments with identical electrical specifications. The only difference is packaging format: CD4071BPWR is supplied in Tape & Reel format versus Tube format for the original part. Both maintain Active product status with full ROHS3 compliance.

MC14071BDTR2G and NLV14071BDTR2G are onsemi equivalents with Active product status. These parts maintain all critical functional parameters and ROHS3 compliance. Output current specifications are higher (8.8mA versus 3.4mA), and propagation delay is marginally increased (100ns versus 90ns), but both remain within acceptable operating margins for standard OR gate applications. Both are supplied in Tape & Reel packaging.

Selection should prioritize parts with Active product status to ensure long-term availability. CD4071BPWR is recommended as the first choice due to manufacturer continuity with the original part.

Frequently Asked Questions (FAQ)

Q: Can CD4071BPWR directly replace CD4071BPW?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, logic configuration, and 14-TSSOP package. The difference is packaging format: CD4071BPWR uses Tape & Reel while CD4071BPW uses Tube. Functional compatibility is complete.

Q: Are onsemi parts (MC14071BDTR2G, NLV14071BDTR2G) compatible with CD4071BPW?

A: Yes. Both onsemi parts maintain the same logic function, supply voltage range, operating temperature, and 14-TSSOP package. Output current and propagation delay specifications differ slightly but remain within acceptable tolerances for OR gate operation.

Q: What is the difference between MC14071BDTR2G and NLV14071BDTR2G?

A: Both parts are manufactured by onsemi with identical electrical specifications and packaging. The difference is in the base product number designation (MC14071 versus NLV14071), but functional and electrical characteristics are equivalent.

Q: Why is CD4071BPW marked as Last Time Buy?

A: Last Time Buy status indicates limited remaining inventory. Substitution to parts with Active status (CD4071BPWR, MC14071BDTR2G, NLV14071BDTR2G) is recommended for new designs or long-term production requirements.

Q: Does packaging format affect electrical performance?

A: No. Tube and Tape & Reel packaging formats contain identical components. Packaging selection is based on assembly process requirements and volume needs, not electrical function.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts maintain ROHS3 compliance and are suitable for applications requiring environmental compliance certification.
