CD4527BPW Equivalent & Substitute Parts

Part Overview

The CD4527BPW is a BCD Rate Multiplier logic IC manufactured by Texas Instruments in the 4000B series. This component is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. The CD4527BPW is packaged in 16-TSSOP format with tube packaging and is designed for surface mount applications across industrial and commercial temperature ranges.

Substitute parts become necessary due to the Last Time Buy status of the CD4527BPW. Identifying equivalent components ensures design continuity and supply chain reliability for applications requiring BCD rate multiplication functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4527BPW is determined by strict equivalence across the following parameters:

• Logic Type: BCD Rate Multiplier (functional equivalence)
• Number of Bits: 4 (pin count and functional capacity)
• Supply Voltage Range: 3V ~ 18V (operational compatibility)
• Operating Temperature Range: -55°C ~ 125°C (environmental compatibility)
• Package / Case: 16-TSSOP (0.173", 4.40mm Width) (physical and electrical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)
• RoHS Status: ROHS3 Compliant (regulatory compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

The CD4527BPWR qualifies as a direct substitute based on identical electrical specifications and package format. The primary difference is packaging configuration: the CD4527BPW uses tube packaging while the CD4527BPWR uses Tape & Reel (TR) format. Both are manufactured by Texas Instruments and maintain full functional and electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The CD4527BPWR is the direct substitute for the CD4527BPW. Both components are manufactured by Texas Instruments and maintain identical electrical and functional specifications. The CD4527BPWR carries Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the CD4527BPW.

Selection between these parts should be based on packaging requirements and procurement strategy. The CD4527BPW in tube packaging is suitable for lower-volume applications or manual assembly processes. The CD4527BPWR in Tape & Reel format is optimized for high-volume automated assembly operations.

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and handling compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can the CD4527BPWR directly replace the CD4527BPW in existing designs?

A: Yes. The CD4527BPWR is a direct electrical and functional equivalent. Both components feature identical pin configurations, electrical specifications, and operating parameters. The only difference is packaging format (Tube vs. Tape & Reel).

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

A: Packaging format affects procurement and assembly processes. Tube packaging is used for manual handling and lower-volume applications. Tape & Reel format is designed for automated pick-and-place assembly systems and high-volume production. Electrical performance and component functionality remain identical.

Q: Why is the CD4527BPW marked as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued production of this part number. Existing inventory is available for purchase, but no future production is planned. The CD4527BPWR in Tape & Reel format remains in Active production status.

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

A: No. Both the CD4527BPW and CD4527BPWR maintain identical RoHS3 compliance, REACH status, and moisture sensitivity ratings. They are fully equivalent from a regulatory and environmental standpoint.

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

A: Substitution is determined by matching Logic Type (BCD Rate Multiplier), Number of Bits (4), Supply Voltage Range (3V ~ 18V), Operating Temperature Range (-55°C ~ 125°C), Package / Case (16-TSSOP), Mounting Type (Surface Mount), and compliance certifications (RoHS3, MSL 1).
