Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4532BPWE4 is determined by strict equivalence across the following critical parameters:

• Functional Type: Priority Encoder with identical 1 x 8:3 circuit configuration
• Electrical Specifications: Matching voltage supply range (3V ~ 18V), output current ratings (6.8mA), and operating temperature range (-55°C ~ 125°C)
• Package Compatibility: Identical 16-TSSOP surface mount package with matching physical dimensions
• Base Product Number: CD4532 series from Texas Instruments
• Compliance Standards: ROHS3 compliance and MSL rating equivalence

The substitute part CD4532BPWR meets all these criteria and is therefore electrically and mechanically interchangeable with the CD4532BPWE4.

Parameter Comparison

Engineering Selection Recommendations

The CD4532BPWR is the direct substitute for the CD4532BPWE4. Both parts are manufactured by Texas Instruments, share identical electrical and mechanical specifications, and maintain equivalent compliance certifications (ROHS3, MSL 1).

The primary distinction is product status: the CD4532BPWE4 is Obsolete, while the CD4532BPWR is Active. This status difference makes the CD4532BPWR the preferred selection for new designs, ongoing production, and component replenishment. The CD4532BPWR is available in Tape & Reel packaging format, which is standard for high-volume manufacturing operations.

Both parts are functionally equivalent and can be used interchangeably in applications requiring a Priority Encoder 1 x 8:3 logic circuit with the specified electrical and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can the CD4532BPWR directly replace the CD4532BPWE4 in existing designs?

A: Yes. The CD4532BPWR is electrically and mechanically equivalent to the CD4532BPWE4. Both parts feature identical circuit configuration (1 x 8:3 Priority Encoder), voltage supply range (3V ~ 18V), output current specifications (6.8mA), operating temperature range (-55°C ~ 125°C), and 16-TSSOP package dimensions. No design modifications are required.

Q: What is the difference between the CD4532BPWE4 and CD4532BPWR packaging?

A: The CD4532BPWE4 is supplied in Tube packaging, while the CD4532BPWR is supplied in Tape & Reel (TR) format. Both contain the same integrated circuit. Tape & Reel packaging is optimized for automated assembly processes, while Tube packaging is suitable for manual handling and smaller quantity orders.

Q: Why is the CD4532BPWE4 listed as Obsolete?

A: The Obsolete status indicates that Texas Instruments has discontinued active production and support for this specific part number variant. The CD4532BPWR remains Active and is the current production equivalent.

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

A: No. Both the CD4532BPWE4 and CD4532BPWR maintain identical compliance certifications: ROHS3 Compliant, Moisture Sensitivity Level 1 (Unlimited), REACH Unaffected, and equivalent ECCN and HTSUS classifications.

Q: Can I use the CD4532BPWR in applications originally designed for the CD4532BPWE4?

A: Yes. The CD4532BPWR is a direct functional and physical equivalent. All electrical characteristics, thermal specifications, and package dimensions are identical, making it suitable for all applications utilizing the CD4532BPWE4.
