The CD4048BM96 qualifies as a manufacturer-recommended substitute based on identical electrical specifications and package geometry. The primary distinction is packaging format: the CD4048BM is supplied in Tube packaging, while the CD4048BM96 is supplied in Tape & Reel (TR) format. Both parts share the same base product number (CD4048) and belong to the 4000B logic series.

Parameter Comparison

Engineering Selection Recommendations

The CD4048BM96 is the manufacturer-recommended substitute for the CD4048BM. Both parts are electrically and mechanically identical, with all functional parameters, electrical characteristics, and compliance certifications matching exactly. The CD4048BM96 maintains Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the CD4048BM.

Selection between these parts should be based on packaging requirements and procurement strategy. The Tube packaging of the CD4048BM is suitable for lower-volume applications and manual assembly processes. The Tape & Reel (TR) packaging of the CD4048BM96 is optimized for automated pick-and-place assembly and higher-volume production runs. Both parts carry identical ROHS3 compliance and REACH Unaffected certifications, meeting equivalent regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the CD4048BM96 be used as a direct replacement for the CD4048BM in existing designs?

A: Yes. The CD4048BM96 is electrically and mechanically identical to the CD4048BM. All functional parameters, output current ratings, supply voltage range, operating temperature range, and package dimensions are equivalent. No circuit modifications are required.

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

A: Tube packaging supplies individual components in a plastic tube, suitable for manual handling and lower-volume assembly. Tape & Reel (TR) packaging supplies components on a continuous reel in standardized tape format, optimized for automated assembly equipment. Both formats contain the same electronic component with identical electrical performance.

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

A: No. Both the CD4048BM and CD4048BM96 carry identical ROHS3 compliance and REACH Unaffected certifications. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both parts, indicating no special moisture handling requirements.

Q: Why is the CD4048BM listed as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. The CD4048BM96 remains in Active status and is the recommended path forward for continued supply and design continuity.

Q: Are the 16-SOIC packages identical between both parts?

A: Yes. Both parts use the 16-SOIC package with identical dimensions: 0.154" (3.90mm) width. Pin configuration, spacing, and PCB footprint are identical, ensuring direct compatibility on existing circuit boards.
