CD4099BMT Equivalent & Substitute Parts

Part Overview

The CD4099BMT is an 8-bit addressable latch IC manufactured by Texas Instruments, classified as a D-Type, Addressable logic component with a 1:8 circuit configuration. This device operates across a wide supply voltage range of 3V to 18V and is housed in a 16-SOIC surface mount package. The CD4099BMT is currently listed as obsolete, which necessitates identification of active equivalent alternatives to maintain design continuity and ensure long-term component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4099BMT is determined by strict equivalence across the following critical parameters:

• Logic Type and Circuit Configuration: D-Type, Addressable 1:8 topology
• Electrical Performance: Supply voltage range 3V ~ 18V, propagation delay 50ns, output current 6.8mA
• Package Specification: 16-SOIC surface mount form factor with identical physical dimensions
• Compliance Standards: ROHS3 compliance, REACH unaffected status, and MSL rating
• Base Product Number: CD4099 series designation

The CD4099BM96 meets all these criteria as a parametric equivalent, with the primary distinction being its active product status and alternative packaging configuration (Cut Tape and Digi-Reel).

Parameter Comparison

Engineering Selection Recommendations

The CD4099BM96 is the direct parametric equivalent for the obsolete CD4099BMT. All electrical specifications, thermal characteristics, and mechanical package dimensions are identical. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment across applications.

The primary advantage of the CD4099BM96 is its active product status, which guarantees ongoing availability and manufacturing support from Texas Instruments. The CD4099BMT, being obsolete, presents supply chain risk and potential discontinuation of manufacturing.

Packaging configuration differs between the two parts: the CD4099BMT is supplied in standard packaging, while the CD4099BM96 is available in Cut Tape and Digi-Reel formats. This distinction does not affect electrical or mechanical compatibility and relates only to procurement and handling methods.

For new designs or component replenishment, the CD4099BM96 is the recommended selection. For existing inventory management of CD4099BMT units, direct pin-for-pin and functional replacement with CD4099BM96 is supported without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the CD4099BM96 directly replace the CD4099BMT in existing circuits?

A: Yes. The CD4099BM96 is a parametric equivalent with identical electrical performance, supply voltage range, propagation delay, output current ratings, and operating temperature specifications. Pin configuration and package dimensions are identical, enabling direct substitution without circuit redesign.

Q: What is the difference between the CD4099BMT and CD4099BM96?

A: The primary difference is product status: CD4099BMT is obsolete, while CD4099BM96 is active. Packaging format also differs—CD4099BMT uses standard packaging, while CD4099BM96 is supplied in Cut Tape and Digi-Reel configurations. All electrical and mechanical specifications are identical.

Q: Why is the CD4099BMT listed as obsolete?

A: Obsolescence indicates that Texas Instruments has discontinued active manufacturing and support for this specific part number variant. The CD4099BM96 remains in active production as the current equivalent offering.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the CD4099BMT and CD4099BM96 maintain identical ROHS3 compliance status and REACH unaffected designation. Moisture sensitivity level (MSL 1 - Unlimited) is the same for both parts.

Q: What supply voltage range do these components support?

A: Both the CD4099BMT and CD4099BM96 operate across a supply voltage range of 3V to 18V, providing compatibility with a wide range of logic system designs.

Q: Is the 16-SOIC package identical between both parts?

A: Yes. Both components use the 16-SOIC package with identical physical dimensions of 0.154 inches (3.90mm width). PCB footprints and land patterns are interchangeable.
