CD4035BPWG4 Equivalent & Substitute Parts

Part Overview

The CD4035BPWG4 is a 4-bit shift register from Texas Instruments' 4000B logic series, designed for parallel or serial to serial conversion applications. It features complementary output configuration and operates across a wide supply voltage range of 3V to 18V with an operating temperature range of -55°C to 125°C. The device is packaged in a 16-TSSOP surface mount package.

The CD4035BPWG4 is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications utilizing this shift register configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4035BPWG4 is determined by strict equivalence across the following critical parameters:

• Logic Configuration: Shift register with 1 element, 4 bits per element, complementary output
• Functional Capability: Parallel or serial to serial conversion
• Electrical Specifications: Supply voltage range 3V ~ 18V, operating temperature -55°C ~ 125°C
• Physical Package: 16-TSSOP surface mount package with identical dimensions (0.173", 4.40mm width)
• Series Designation: 4000B logic family
• Compliance Standards: ROHS3 compliant, REACH unaffected, MSL 1

The CD4035BPWR qualifies as a direct substitute based on identical electrical characteristics, functional specifications, and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The CD4035BPWR is the manufacturer-recommended substitute for the obsolete CD4035BPWG4. Both devices are manufactured by Texas Instruments and maintain identical electrical and functional specifications across all critical parameters.

The CD4035BPWR offers the advantage of active product status, ensuring continued availability and manufacturer support. Both parts maintain full ROHS3 compliance and REACH compliance status, meeting current regulatory requirements for electronic component manufacturing and use.

The packaging format difference (bulk versus tape & reel) reflects standard industry practices for active versus obsolete product lines and does not affect electrical or functional compatibility. Selection between these parts should be based on supply chain availability and procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the CD4035BPWR directly replace the CD4035BPWG4 in existing designs?

A: Yes. The CD4035BPWR is electrically and functionally identical to the CD4035BPWG4. Both devices share the same 16-TSSOP package configuration, supply voltage range, operating temperature specifications, and shift register functionality. No design modifications are required.

Q: What is the significance of the product status difference between these parts?

A: The CD4035BPWG4 is classified as obsolete, indicating it is no longer in active production. The CD4035BPWR maintains active status, ensuring ongoing manufacturer support, availability, and compliance with current standards. For new designs or ongoing production, the active part is the preferred selection.

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

A: No. Both the CD4035BPWG4 and CD4035BPWR maintain identical ROHS3 compliance and REACH compliance status. Moisture sensitivity level (MSL 1) is identical for both parts.

Q: Does the packaging format (bulk versus tape & reel) affect compatibility?

A: No. Packaging format differences relate to supply and handling methods only. The electrical and functional characteristics of the device remain unchanged. Tape & reel packaging is standard for active production parts and offers advantages for automated assembly processes.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in logic type (shift register), element and bit configuration (1 element, 4 bits), output type (complementary), functional capability (parallel or serial to serial conversion), supply voltage range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), and physical package (16-TSSOP). All parameters must match for direct substitution.
