CD4011BPW NAND Gate IC Equivalent & Substitute Parts

Part Overview

The CD4011BPW is a 4-channel 2-input NAND gate logic IC manufactured by Texas Instruments in 14-TSSOP surface mount packaging. This part is discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. The CD4011BPW operates across a wide supply voltage range of 3V to 18V, making it suitable for both low-voltage and standard logic applications. Equivalent parts maintain identical functional specifications and package form factors while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD4011BPW is determined by strict equivalence across the following parameters: logic type (NAND Gate), circuit count (4 channels), input count (2 inputs per gate), supply voltage range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), package type (14-TSSOP), and compliance certifications (ROHS3, REACH Unaffected). All substitute parts listed maintain these core specifications. Differences in output current ratings and propagation delay do not disqualify substitution when the substitute meets or exceeds the original part's performance envelope. Packaging format (tube, cut tape, or tape & reel) represents a logistics variation and does not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

CD4011BPWR (Texas Instruments) is the primary direct substitute for CD4011BPW. Both parts are manufactured by Texas Instruments, share identical electrical specifications, and maintain active product status. The only difference is packaging format: CD4011BPWR is supplied in cut tape and Digi-Reel format versus the original tube packaging. This part is recommended for applications requiring continuity with the original Texas Instruments design and is available in high volume (43,250 pcs in stock).

MC14011BDTR2G (onsemi) and NLV14011BDTR2G (onsemi) are manufacturer-recommended alternatives from onsemi. Both parts maintain full functional equivalence across all critical parameters: supply voltage range, operating temperature, logic configuration, and package type. The onsemi variants feature improved output current capability (8.8mA versus 3.4mA) and faster propagation delay (80ns versus 90ns), representing performance enhancements over the original part. Both onsemi parts carry active product status and full compliance certifications. Selection between MC14011BDTR2G and NLV14011BDTR2G depends on supply chain availability and procurement preferences, as both are electrically and mechanically identical.

Frequently Asked Questions (FAQ)

Q: Can CD4011BPWR be used as a direct replacement for CD4011BPW?

A: Yes. CD4011BPWR is a direct functional equivalent manufactured by Texas Instruments with identical electrical specifications. The difference is packaging format: CD4011BPWR uses cut tape and Digi-Reel packaging instead of tube. No circuit modifications are required.

Q: What is the difference between the Texas Instruments and onsemi substitutes?

A: All three substitute parts (CD4011BPWR, MC14011BDTR2G, NLV14011BDTR2G) are functionally equivalent and pin-compatible. The onsemi parts (MC14011BDTR2G and NLV14011BDTR2G) offer higher output current (8.8mA versus 3.4mA) and faster propagation delay (80ns versus 90ns). These represent performance improvements and do not affect compatibility.

Q: Are the onsemi parts MC14011BDTR2G and NLV14011BDTR2G interchangeable?

A: Yes. Both onsemi parts are electrically and mechanically identical. They differ only in part number designation and supply chain sourcing. Either part can be selected based on availability and procurement requirements.

Q: Does the 14-TSSOP package remain the same across all substitutes?

A: Yes. All substitute parts use the 14-TSSOP (0.173", 4.40mm Width) surface mount package. No PCB layout modifications are required when switching between any of these parts.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CD4011BPWR, MC14011BDTR2G, and NLV14011BDTR2G are all ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH Unaffected status, matching the original CD4011BPW compliance profile.

Q: What is the supply voltage range for all substitute parts?

A: All substitute parts operate across 3V to 18V supply voltage range, identical to the original CD4011BPW. This wide range supports both low-voltage and standard logic applications without modification.
