CD4512BM96 Equivalent & Substitute Parts

Part Overview

The CD4512BM96 is a Data Selector/Multiplexer integrated circuit manufactured by Texas Instruments, configured as a 1 x 8:1 multiplexer in a 16-SOIC surface mount package. This device operates across a dual supply voltage range of 3V to 18V and supports operating temperatures from -55°C to 125°C. The part is currently active in production with 25,400 units in stock. Substitute parts become necessary when the original packaging format (Cut Tape) is unavailable, when product status changes affect supply chain continuity, or when alternative manufacturer sources are required for procurement flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4512BM96 is determined by strict adherence to the following parameters:

Primary Substitution Criteria:

• Circuit configuration: 1 x 8:1 multiplexer topology
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Voltage supply range: 3V ~ 18V minimum
• Operating temperature range: -55°C ~ 125°C minimum
• Series classification: 4000B logic family

Secondary Compatibility Parameters:

• Output current specifications (High/Low)
• Voltage supply source configuration (Dual vs. Single Supply)
• RoHS and compliance certifications

Substitute parts are grouped into two categories: parametric equivalents (identical electrical and mechanical specifications) and manufacturer-recommended alternatives (functionally equivalent with minor parameter variations).

Parameter Comparison

Engineering Selection Recommendations

CD4512BMT (Parametric Equivalent): This Texas Instruments part maintains identical electrical and mechanical specifications to the CD4512BM96, including dual supply voltage source configuration and output current ratings. The primary distinction is packaging format (Tape & Reel versus Cut Tape) and product status (Discontinued at DiGi Electronics). Selection of CD4512BMT is appropriate when Cut Tape packaging is unavailable and Tape & Reel format is acceptable for assembly operations. Current inventory of 1,899 units is available. Both parts carry ROHS3 compliance and identical certifications.

MC14512BDG (MFR Recommended): This onsemi alternative provides functional equivalence within the 4000B logic family with identical circuit configuration, package, and operating temperature range. Notable parameter variations include single supply voltage source operation (versus dual supply) and elevated output current specifications (8.8mA versus 6.8mA). The MC14512BDG is classified as Obsolete. Selection of this part requires confirmation that single supply operation and higher output current are compatible with circuit requirements. Current inventory of 1,024 units is available. ROHS3 compliance and certifications are maintained.

Frequently Asked Questions (FAQ)

Q: Can CD4512BMT be used as a direct replacement for CD4512BM96?

A: Yes. CD4512BMT is a parametric equivalent with identical electrical specifications, circuit configuration, and package dimensions. The difference is packaging format: CD4512BMT is supplied in Tape & Reel format while CD4512BM96 is supplied in Cut Tape format. Both are suitable for surface mount assembly.

Q: What is the key difference between CD4512BMT and MC14512BDG?

A: Both parts share the same 1 x 8:1 multiplexer configuration and 16-SOIC package. The primary differences are: (1) Voltage supply source—CD4512BMT uses dual supply while MC14512BDG uses single supply; (2) Output current—MC14512BDG specifies 8.8mA versus 6.8mA for CD4512BMT; (3) Manufacturer—Texas Instruments versus onsemi; (4) Product status—CD4512BMT is discontinued while MC14512BDG is obsolete.

Q: Is the 16-SOIC package identical across all three parts?

A: Yes. All three parts use the 16-SOIC package with 0.154" width and 3.90mm dimensions. They are mechanically interchangeable in terms of PCB footprint and assembly process.

Q: What does "Discontinued at DiGi Electronics" mean for CD4512BMT?

A: This status indicates the part is no longer actively stocked or distributed through DiGi Electronics. However, the part may remain available through other distribution channels or direct manufacturer sources. Inventory of 1,899 units is currently available.

Q: Can MC14512BDG be used if my circuit requires dual supply operation?

A: No. MC14512BDG is specified for single supply operation. Using it in a dual supply circuit would require circuit redesign. If dual supply operation is required, CD4512BM96 or CD4512BMT must be selected.

Q: Are all three parts RoHS compliant?

A: Yes. CD4512BM96, CD4512BMT, and MC14512BDG are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All parts are REACH Unaffected.
