FFF CompatibilityHoused in an identical TO-252 (DPAK) package with standard pinouts (Pin 1: Gate, Pin 2/Tab: Drain, Pin 3: Source), enabling a seamless physical drop-in placement on the PCB.Dimensions and mounting style are fully identical, allowing the part to match the existing mechanical outline and solder footprint.Meets or exceeds all critical electrical characteristics of the obsolete FDD6690A, offering a 30V breakdown voltage, better RDS(on), and equal or higher current/power handling.Shares the exact TO-252 package structure and industry-standard pin assignment.Matches the physical package dimensions and surface-mount configuration of the original part.Delivers a 30V breakdown voltage with a lower on-resistance and significantly higher continuous current capacity, while keeping power dissipation nearly identical at 54W.
AI Summary

FDD6690A by onsemi: N-Channel 30 V 12A (Ta), 46A (Tc) 3.3W (Ta), 56W (Tc) Surface Mount TO-252AA.

This is the highest-confidence drop-in alternative. It features an identical TO-252 package, a matching 30V breakdown rating, and offers a lower RDS(on) of 6 mOhm alongside a higher 50A continuous current handling to minimize thermal stresses.

  • Fully active and long-lived replacement part with zero end-of-life risk.
  • Superior maximum RDS(on) of 6 mOhm compared to the original 12 mOhm, reducing conduction losses.
  • Higher continuous drain current rating of 50A (Tc) compared to the original 46A (Tc).

A highly reliable second-source alternative from Taiwan Semiconductor. It matches the original's form factor and breakdown voltage while heavily improving overall conduction performance with a 6 mOhm RDS(on) and a robust 70A current ceiling.

  • Fully active and in-production status.
  • Significantly lower RDS(on) of 6 mOhm versus the original 12 mOhm.
  • Significantly higher continuous current rating of 70A (Tc) compared to the original 46A (Tc).

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.

Frequently asked questions

Yes. The onsemi FDD6690A is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
