CD4572UBPWRE4 Equivalent & Substitute Parts

Part Overview

The CD4572UBPWRE4 is a CMOS logic integrated circuit configured as a hexadecimal gate with NOR/NAND/INVERT functionality. It contains 6 circuits with 8 total inputs arranged as (1, 1, 2, 2, 1, 1) and features differential output type. The device is housed in a 16-TSSOP surface mount package and operates across a wide supply voltage range of 3V to 18V with an operating temperature range of -55°C to 125°C.

The CD4572UBPWRE4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4572UBPWRE4 is determined by strict equivalence across the following critical parameters:

Logic configuration and gate type must remain NOR/NAND/INVERT with identical circuit count (6) and input arrangement (1, 1, 2, 2, 1, 1). Output type must be differential with matching output current specifications (6.8mA high and low). Supply voltage range must encompass or match the 3V to 18V specification. Operating temperature range must cover -55°C to 125°C. Package type must be 16-TSSOP surface mount with identical physical dimensions (0.173", 4.40mm Width). Series designation must be 4000B. Compliance certifications including ROHS3 and MSL rating must be maintained.

The CD4572UBPWR is identified as the manufacturer-recommended substitute and meets all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The CD4572UBPWR is the direct substitute for the CD4572UBPWRE4. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the CD4572UBPWRE4 is discontinued while the CD4572UBPWR maintains active status, ensuring ongoing availability and supply chain reliability.

Both parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), satisfying regulatory and environmental requirements. The packaging difference between tube (main part) and tape & reel (substitute) reflects standard distribution formats and does not affect functional compatibility or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the CD4572UBPWR be used as a direct replacement for the CD4572UBPWRE4?

A: Yes. The CD4572UBPWR is electrically and mechanically identical to the CD4572UBPWRE4. All functional parameters, electrical specifications, and package dimensions are equivalent. The substitute is suitable for direct board-level replacement.

Q: What is the difference between the tube and tape & reel packaging?

A: Tube packaging (CD4572UBPWRE4) is typically used for lower-volume orders and manual handling. Tape & reel packaging (CD4572UBPWR) is designed for automated assembly processes and higher-volume production. Both contain identical components with no functional difference.

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

A: No. Both the CD4572UBPWRE4 and CD4572UBPWR maintain identical ROHS3 compliance status and MSL rating of 1 (Unlimited). Regulatory and environmental certifications are equivalent.

Q: Why is the CD4572UBPWRE4 discontinued?

A: The CD4572UBPWRE4 has been discontinued at DiGi Electronics. The CD4572UBPWR remains in active production and is the recommended source for ongoing component procurement.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Supply voltage range (3V to 18V), operating temperature range (-55°C to 125°C), output current specifications (6.8mA high and low), and all logic gate configurations are identical between the CD4572UBPWRE4 and CD4572UBPWR.
