UCC28517DW Equivalent & Substitute Parts

Part Overview

The UCC28517DW is a Power Factor Correction (PFC) controller IC manufactured by Texas Instruments, designed for average current mode operation at 200kHz switching frequency. This device is classified as Last Time Buy, indicating end-of-life status. The UCC28517DW is packaged in 20-SOIC surface mount configuration and operates across a 9.7V to 18V supply voltage range with -40°C to 105°C temperature capability. Due to its Last Time Buy status, identifying functionally equivalent substitute parts is essential for design continuity and long-term supply chain planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCC28517DW is determined by strict equivalence across the following critical parameters:

• Control Mode: Average Current mode operation
• Switching Frequency: 200kHz
• Supply Voltage Range: 9.7V ~ 18V
• Startup Current: 100 µA
• Package Type: 20-SOIC surface mount
• Operating Temperature Range: -40°C ~ 105°C
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The UCC28512DWR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format (Tape & Reel versus Tube) and product status (Active versus Last Time Buy).

Parameter Comparison

Engineering Selection Recommendations

Selection between these parts should be based on:

• Supply Chain Requirements: The UCC28512DWR provides long-term availability as an Active product
• Packaging Format Compatibility: The UCC28512DWR is supplied in Tape & Reel format, suitable for automated assembly processes, while the UCC28517DW is supplied in Tube format
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting environmental and regulatory requirements

Frequently Asked Questions (FAQ)

Q: Can the UCC28512DWR directly replace the UCC28517DW in existing designs?

A: Yes. The UCC28512DWR is electrically identical to the UCC28517DW across all specified parameters, including control mode, switching frequency, supply voltage range, startup current, operating temperature, and package configuration. No design modifications are required.

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

A: Tube packaging is suitable for manual handling and small-volume applications. Tape & Reel packaging is optimized for automated pick-and-place assembly processes and high-volume production. Both formats contain the same component in the same 20-SOIC package.

Q: Why is the UCC28517DW marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued this part number. The UCC28512DWR represents the active product line continuation with identical electrical specifications.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate across the identical temperature range (-40°C to 105°C) and share all electrical specifications. Performance in PFC applications is equivalent.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the UCC28517DW and UCC28512DWR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
