Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4035BM is determined by strict equivalence across the following critical parameters:

• Logic function: Shift Register with 1 element, 4 bits per element
• Output configuration: Complementary output type
• Functional capability: Parallel or Serial to Serial conversion
• Electrical specifications: Supply voltage range 3V ~ 18V, operating temperature -55°C ~ 125°C
• Package specification: 16-SOIC form factor with identical pin configuration
• Compliance standards: ROHS3 compliance, MSL Level 1

The substitute part CD4035BM96 maintains identical electrical and functional characteristics while differing only in packaging format (Tape & Reel versus Tube) and product status (Active versus Last Time Buy).

Parameter Comparison

Engineering Selection Recommendations

The CD4035BM96 is a direct functional equivalent to the CD4035BM. Both parts share identical electrical specifications, pin configuration, and logic functionality. The primary distinction is product lifecycle status: the CD4035BM is Last Time Buy while the CD4035BM96 maintains Active status with ongoing manufacturer support.

For new designs and production applications requiring continued component availability, the CD4035BM96 is the appropriate selection. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring compatibility with current manufacturing and environmental standards. The difference in packaging format (Tube versus Tape & Reel) affects supply chain logistics but does not impact electrical or functional performance.

Frequently Asked Questions (FAQ)

Q: Are CD4035BM and CD4035BM96 pin-for-pin compatible?

A: Yes. Both parts use the 16-SOIC package with identical pin assignments. No circuit modifications are required for substitution.

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

A: Tube packaging contains individual components in a plastic tube for manual handling. Tape & Reel packaging places components on continuous tape for automated assembly equipment. Electrical and functional performance are identical.

Q: Can CD4035BM96 replace CD4035BM in existing designs?

A: Yes. The CD4035BM96 is electrically and functionally equivalent. No design changes are necessary.

Q: Why is CD4035BM marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production. CD4035BM96 remains in active production and is the recommended source for future component procurement.

Q: Are both parts RoHS compliant?

A: Yes. Both CD4035BM and CD4035BM96 are ROHS3 compliant with MSL Level 1 rating.

Q: What supply voltage range do these parts support?

A: Both parts operate across 3V to 18V supply voltage range, supporting a wide range of logic system applications.
