CD4512BM Equivalent & Substitute Parts

Part Overview

The CD4512BM is a Data Selector/Multiplexer integrated circuit featuring a 1 x 8:1 configuration in a 16-SOIC package. Manufactured by Texas Instruments as part of the 4000B logic series, this component is currently discontinued at DiGi Electronics. The CD4512BM operates across a dual supply voltage range of 3V to 18V with an operating temperature range of -55°C to 125°C. Due to its discontinued status, equivalent substitute parts are necessary for ongoing design implementations and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4512BM is determined by the following critical parameters:

• Circuit Configuration: Must be 1 x 8:1 Data Selector/Multiplexer
• Package Type: Must be 16-SOIC (0.154", 3.90mm Width) for mechanical compatibility
• Voltage Supply Range: Must support 3V ~ 18V operation
• Operating Temperature Range: Must support -55°C ~ 125°C
• Mounting Type: Must be Surface Mount
• RoHS Compliance: Must maintain ROHS3 Compliant status

Substitute parts are grouped into two categories based on electrical characteristics:

Category 1 - Texas Instruments Direct Substitutes (Dual Supply): Parts maintaining identical voltage supply source (Dual Supply) and output current specifications (6.8mA, 6.8mA). These provide direct functional equivalence with no design modifications required.

Category 2 - onsemi Cross-Manufacturer Substitutes (Single Supply): Parts with equivalent circuit configuration and package but operating under Single Supply voltage source with higher output current specifications (8.8mA, 8.8mA). These require design verification for supply architecture compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CD4512BM96 (Texas Instruments)

CD4512BM96 is the recommended primary substitute. It maintains identical electrical specifications (Dual Supply, 6.8mA output current) and mechanical compatibility (16-SOIC package). The part is currently Active in product status with 25,400 units in stock, ensuring long-term availability. This substitute requires no design modifications and provides direct functional equivalence.

Secondary Substitute: MC14512BDR2G (onsemi)

MC14512BDR2G is the manufacturer-recommended substitute from onsemi. It maintains the 1 x 8:1 circuit configuration, 16-SOIC package, and full voltage supply range (3V ~ 18V). The part is currently Active with 2,000 units in stock. The key difference is the Single Supply voltage source architecture and higher output current specification (8.8mA vs. 6.8mA). This substitute is suitable for designs where the supply architecture can accommodate Single Supply operation.

Tertiary Substitute: MC14512BDG (onsemi)

MC14512BDG provides equivalent circuit functionality and package compatibility but carries Obsolete product status. This part should be considered only when MC14512BDR2G is unavailable, as its discontinued status limits long-term procurement viability.

Frequently Asked Questions (FAQ)

Q: Can CD4512BM96 be used as a direct replacement for CD4512BM?

A: Yes. CD4512BM96 maintains identical electrical specifications including Dual Supply voltage source, output current (6.8mA, 6.8mA), and 16-SOIC package configuration. No design modifications are required.

Q: What is the key difference between CD4512BM and MC14512BDR2G?

A: The primary difference is the voltage supply architecture. CD4512BM operates on Dual Supply, while MC14512BDR2G operates on Single Supply. Both support the 3V ~ 18V voltage range. MC14512BDR2G also specifies higher output current (8.8mA vs. 6.8mA). Design verification is required to confirm Single Supply compatibility.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts use the 16-SOIC (0.154", 3.90mm Width) package, ensuring mechanical and pin compatibility on the PCB.

Q: Do substitute parts maintain RoHS compliance?

A: Yes. All substitute parts listed maintain ROHS3 Compliant status, consistent with the original CD4512BM specification.

Q: Which substitute has the best availability?

A: CD4512BM96 has the highest inventory level at 25,400 units in stock and carries Active product status, providing the most reliable long-term availability.

Q: Can MC14512BDG be used if other substitutes are unavailable?

A: MC14512BDG provides functional equivalence but carries Obsolete product status with only 1,024 units in stock. It should be considered only as a last resort when other Active substitutes are unavailable.
