CD4081BPW Equivalent & Substitute Parts

Part Overview

The CD4081BPW is a 4-channel AND gate logic IC manufactured by Texas Instruments in the 4000B series. This component is currently discontinued at DiGi Electronics but remains available through inventory channels. The part operates across a wide supply voltage range of 3V to 18V and is housed in a 14-TSSOP surface mount package. Due to its discontinued status, equivalent substitute parts from active product lines are necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4081BPW is determined by strict equivalence across the following parameters: logic type (AND gate), circuit count (4 channels), input count (2 inputs per channel), supply voltage range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), and package type (14-TSSOP surface mount). All substitute parts listed maintain these core specifications, ensuring functional and mechanical compatibility. Differences in output current characteristics and propagation delay do not preclude substitution when these parameters remain within acceptable design tolerances.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, CD4081BPWR is the direct Texas Instruments equivalent with active product status and identical electrical specifications to the CD4081BPW. This part maintains the same output current characteristics (3.4mA) and propagation delay (90ns @ 15V, 50pF), differing only in packaging format (Cut Tape & Digi-Reel versus Tube).

MC14081BDTR2G and NLV14081BDTR2G are onsemi alternatives that maintain full functional compatibility across all core parameters. Both parts feature higher output current capability (8.8mA versus 3.4mA) and slightly increased propagation delay (100ns versus 90ns). Both onsemi variants carry active product status and ROHS3 compliance. Selection between these options depends on supply chain availability, packaging requirements (Tape & Reel format), and output current requirements for the specific application.

Frequently Asked Questions (FAQ)

Q: Can CD4081BPWR directly replace CD4081BPW? A: Yes. Both parts are manufactured by Texas Instruments, share identical electrical specifications, and are housed in the same 14-TSSOP package. The difference is packaging format: CD4081BPW is supplied in Tube packaging, while CD4081BPWR is supplied in Cut Tape & Digi-Reel format.

Q: Are onsemi parts (MC14081BDTR2G and NLV14081BDTR2G) compatible with the CD4081BPW? A: Yes. Both onsemi parts maintain the same logic function, circuit count, input configuration, supply voltage range, and operating temperature range. Output current is higher (8.8mA versus 3.4mA) and propagation delay is slightly increased (100ns versus 90ns), but these differences do not prevent functional substitution in applications designed for the CD4081BPW specifications.

Q: What is the difference between MC14081BDTR2G and NLV14081BDTR2G? A: Both parts are manufactured by onsemi with identical electrical specifications and 14-TSSOP packaging. The primary distinction is the base product number designation (MC14081 versus NLV14081), which reflects different product lines within onsemi's logic IC portfolio. Both are supplied in Tape & Reel format and carry active product status.

Q: Why is the CD4081BPW discontinued? A: The CD4081BPW has been discontinued at DiGi Electronics. Active alternatives from both Texas Instruments and onsemi remain available to support ongoing production and new design requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. The CD4081BPW and all listed substitute parts (CD4081BPWR, MC14081BDTR2G, NLV14081BDTR2G) are ROHS3 compliant.
