AI Summary

ISL8272MAIRZ by Renesas Electronics Corporation: Non-Isolated PoL Module, Digital DC DC Converter 1 Output 0.6 ~ 5V 50A 4.5V - 14V Input.

This is a direct sibling part from the same family that is identical in form and pinout, but utilizes the FC02 firmware revision instead of FC01. It serves as a direct drop-in replacement if register-level software compatibility allows. Note that this sibling part is also discontinued.

  • Same 58-HDA 18mm x 23mm package with identical pinout and layout.
  • Direct physical drop-in replacement with identical layout footprint.
  • Same 50A continuous output current rating and 4.5V to 14V input range.
  • Uses firmware revision FC02 instead of FC01, which may introduce minor PMBus telemetry differences.
  • Part is also obsolete, meaning it must be sourced from legacy distributor stock.

The ISL8273M is a direct drop-in sibling that features the exact same package and pin configuration but offers an upgraded output current capacity of up to 80A. This provides exceptional thermal and power headroom for existing layouts, though the part itself is also obsolete.

  • Same 58-pin HDA layout with matching pin assignments for all control and power pins.
  • Identical package dimensions of 18mm x 23mm x 7.45mm.
  • Meets and exceeds original electrical performance with higher current capacity (80A).
  • Also obsolete, which limits long-term design sustainability.
  • High capacity may be underutilized or require configuration tuning in 50A applications.

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.
