CD4073BPW Equivalent & Substitute Parts

Part Overview

The CD4073BPW is a 3-channel AND gate logic IC manufactured by Texas Instruments, housed in a 14-TSSOP surface mount package. This component operates across a wide supply voltage range of 3V to 18V and is compliant with ROHS3 and REACH standards. The CD4073BPW carries a Last Time Buy product status, indicating that this specific packaging configuration (Tube) is being discontinued. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications requiring this logic function.

Substitute Part Grouping Explanation

Substitution of the CD4073BPW is determined by strict equivalence across the following critical parameters:

• Logic function: 3-channel AND gate with 3 inputs per channel
• Electrical performance: Supply voltage range 3V ~ 18V, quiescent current 1 µA maximum, output current 3.4mA, propagation delay 90ns @ 15V with 50pF load
• Package specification: 14-TSSOP surface mount form factor with identical pin configuration
• Compliance certifications: ROHS3 and REACH status
• Operating temperature range: -55°C ~ 125°C

The CD4073BPWR qualifies as a direct substitute based on identical electrical specifications, logic configuration, and package type. The primary difference is packaging format: the CD4073BPW is supplied in Tube packaging with Last Time Buy status, while the CD4073BPWR is supplied in Cut Tape (CT) & Digi-Reel® format with Active product status.

Parameter Comparison

Engineering Selection Recommendations

The CD4073BPWR is a direct functional and electrical equivalent to the CD4073BPW. Both parts share identical logic specifications, electrical performance characteristics, and compliance certifications. The CD4073BPWR maintains Active product status from Texas Instruments, ensuring continued availability and supply chain stability. For new designs or production transitions, the CD4073BPWR is the appropriate selection due to its Active status and standard distribution packaging format. Existing designs using the CD4073BPW can transition to the CD4073BPWR without circuit modification, as pin configuration and electrical behavior are identical.

Frequently Asked Questions (FAQ)

Q: Can the CD4073BPWR directly replace the CD4073BPW in existing designs?

A: Yes. Both parts are electrically and functionally identical with the same 14-TSSOP pin configuration. No circuit modifications are required for substitution.

Q: What is the difference between Tube and Cut Tape (CT) & Digi-Reel® packaging?

A: Tube packaging is used for lower-volume applications and manual assembly, while Cut Tape and Digi-Reel® formats are designed for automated pick-and-place assembly. The electrical component and performance are identical; only the packaging and delivery format differ.

Q: Why is the CD4073BPW marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments is discontinuing this specific packaging configuration. The CD4073BPWR in Cut Tape & Digi-Reel® format remains in active production and is the recommended alternative for ongoing supply.

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

A: No. Both the CD4073BPW and CD4073BPWR carry identical ROHS3 and REACH compliance certifications, with MSL rating of 1 (Unlimited).

Q: What are the critical parameters for substitution compatibility?

A: Substitution is valid when the following parameters match: logic type (AND gate), number of circuits (3), number of inputs (3), supply voltage range (3V ~ 18V), output current (3.4mA), propagation delay (90ns @ 15V, 50pF), operating temperature range (-55°C ~ 125°C), and package type (14-TSSOP).
