FFF CompatibilityThe pinout configuration is identical to the target component.Both parts share the identical SOIC-8 package profile.The UCC28083DR has higher UVLO thresholds (12.5 V turn-on / 8.3 V turn-off) compared to the UCC28084DR (4.3 V / 4.1 V), making it unsuitable for low-voltage supply rails.The pinout and assignments of UCC28086DR are identical to UCC28084DR.Both devices use the standard SOIC-8 package (D package) with identical dimensions.The UCC28086DR lacks the 3.5 ms internal soft-start feature of the UCC28084DR, having a soft-start interval of less than 100 µs.
AI Summary

UCC28084DR by Texas Instruments: Half-Bridge, Push-Pull Regulator Positive Output Step-Up/Step-Down DC-DC Controller IC 8-SOIC.

This sibling variant retains the internal soft-start and programmable slope compensation, but has higher UVLO thresholds that require a higher supply voltage.

  • Pin-compatible drop-in replacement
  • Same physical SOIC-8 package and footprint
  • Retains the same 3.5 ms internal soft-start and programmable slope compensation
  • Higher UVLO thresholds (12.5 V / 8.3 V vs 4.3 V / 4.1 V)

This is a direct sibling from the same product series that matches the physical footprint, pinout, and UVLO thresholds, but does not feature the 3.5 ms internal soft-start.

  • Pin-compatible drop-in replacement
  • Same SOIC-8 footprint, package dimensions, and assembly process
  • Identical 4.3 V / 4.1 V UVLO thresholds
  • Lacks 3.5 ms internal soft-start (requires external soft-start circuitry if needed)

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
