CD4502BM Equivalent & Substitute Parts

Part Overview

The CD4502BM is a Buffer, Inverting logic IC manufactured by Texas Instruments, designed for 18V operation in a 16-SOIC surface mount package. This component functions as a 1-element, 6-bit inverting buffer with push-pull output capability. The CD4502BM is classified as Last Time Buy, indicating discontinued production status. Identifying equivalent substitute parts is necessary to ensure continued availability for new designs, production runs, and field replacements where the original part number is no longer procurable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4502BM is determined by strict equivalence across the following critical parameters:

• Logic function: Buffer, Inverting (1 element, 6 bits per element)
• Output configuration: Push-Pull
• Electrical performance: Output current (3.4mA high, 20.4mA low), supply voltage range (3V ~ 18V), operating temperature range (-55°C ~ 125°C)
• Physical form factor: 16-SOIC package with identical dimensions (0.154", 3.90mm width)
• Compliance: ROHS3 Compliant, MSL 1 (Unlimited)

The CD4502BM96 qualifies as a direct substitute based on identical electrical specifications, package geometry, and functional characteristics. The primary difference is packaging format: CD4502BM is supplied in Tube, while CD4502BM96 is supplied in Tape & Reel (TR). Both parts share the same base product number (CD4502) and series designation (4000B).

Parameter Comparison

Engineering Selection Recommendations

The CD4502BM96 is the manufacturer-recommended substitute for the CD4502BM. Both parts are manufactured by Texas Instruments and maintain identical electrical and functional specifications. The CD4502BM96 carries Active product status, ensuring continued availability and support, whereas the CD4502BM is Last Time Buy. For new designs and production applications, the CD4502BM96 is the appropriate selection.

The packaging format difference (Tube versus Tape & Reel) does not affect electrical performance or PCB-level compatibility. Selection between these formats depends on assembly process requirements and volume considerations. The CD4502BM96 in Tape & Reel format is standard for automated pick-and-place assembly operations. Both parts maintain ROHS3 compliance and MSL 1 rating, confirming suitability for standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CD4502BM96 be used as a direct replacement for CD4502BM in existing designs?

A: Yes. The CD4502BM96 is electrically and functionally identical to the CD4502BM. Both parts share the same 16-SOIC package dimensions, pin configuration, and electrical specifications. No circuit modifications are required.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies components in a plastic tube for manual handling and small-volume applications. Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, optimized for automated assembly equipment. Both formats contain the same component with identical specifications.

Q: Why is the CD4502BM marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this specific part number variant. The CD4502BM96 remains in Active production status and is the recommended alternative for continued procurement.

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

A: No. Both the CD4502BM and CD4502BM96 maintain identical ROHS3 compliance, MSL 1 rating, REACH Unaffected status, and ECCN/HTSUS classifications.

Q: Which part should be selected for new production designs?

A: The CD4502BM96 should be selected for new designs due to its Active product status and assured long-term availability. The CD4502BM is suitable only for replacement or repair of existing equipment where the original part number is specified.
