Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4012BM is determined by strict equivalence across the following parameters:

• Logic Type: NAND Gate (2 channels, 4 inputs per channel)
• Supply Voltage Range: 3V ~ 18V
• Quiescent Current: 1 µA maximum
• Operating Temperature Range: -55°C ~ 125°C
• Package: 14-SOIC surface mount
• RoHS3 Compliance and REACH Unaffected status

All substitute parts listed maintain identical logic configuration, voltage specifications, and thermal operating range. Packaging format variations (Tube vs. Tape & Reel) do not affect electrical equivalence but may impact procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

CD4012BM96 is the primary substitute, maintaining identical electrical performance specifications while offering Active product status from the same manufacturer (Texas Instruments). This part is available in Tape & Reel packaging, suitable for automated assembly processes.

MC14012BDG and MC14012BDR2G are onsemi equivalents with Active status. Both parts maintain the same logic configuration, supply voltage range, and operating temperature specifications. Output current specifications are higher (8.8mA vs. 3.4mA), and propagation delay is marginally increased (100ns vs. 90ns). These differences remain within acceptable tolerances for standard NAND gate applications.

NLV14012BDR2G is an onsemi variant with identical electrical characteristics to the MC14012 series, available in Tape & Reel format. All substitute parts carry ROHS3 compliance and REACH Unaffected status, matching the original part's regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can CD4012BM96 be used as a direct replacement for CD4012BM?

A: Yes. CD4012BM96 is electrically identical to CD4012BM, with the same propagation delay (90ns), output current (3.4mA), and all other electrical specifications. The primary difference is packaging format (Tape & Reel vs. Tube) and Active product status.

Q: What are the differences between Texas Instruments and onsemi NAND gate options?

A: All parts maintain identical logic configuration (2 channels, 4 inputs), supply voltage range (3V ~ 18V), and quiescent current (1 µA). onsemi variants (MC14012 and NLV14012 series) have higher output current capability (8.8mA vs. 3.4mA) and slightly longer propagation delay (100ns vs. 90ns). These differences do not affect functional compatibility in standard logic applications.

Q: Does packaging format affect electrical performance?

A: No. Tube and Tape & Reel packaging formats contain identical die and electrical specifications. Packaging selection is determined by assembly process requirements and procurement workflow, not electrical performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and REACH Unaffected designation, matching the original CD4012BM regulatory compliance profile.

Q: Which substitute part offers the best availability?

A: MC14012BDR2G shows the highest inventory level (40,523 pcs) among all listed substitutes, followed by MC14012BDG (3,467 pcs) and NLV14012BDR2G (2,611 pcs).
