 AI Summary | FDD5614P by onsemi: P-Channel 60 V 15A (Ta) 3.8W (Ta), 42W (Tc) Surface Mount TO-252AA. | This active part from Alpha & Omega Semiconductor is a premium, fully compatible upgrade for the obsolete FDD5614P. It shares the exact same package dimensions, pin configuration, and 175°C thermal ceiling, while offering significantly improved current capability and lower conduction losses. Use of the ordering table confirmed that the 'D' prefix corresponds to the correct surface-mount DPAK package variant.
| This active part is a direct physical replacement but has slightly degraded electrical specifications. It matches the high 175°C thermal ceiling of the original part but operates with a slightly reduced continuous drain current limit and higher on-resistance. This part is a reliable alternative if the application does not run near the original current limits.

You searched one part. Parter watches your whole BOM.
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.
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.
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 FDD5614P 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.
The closest qualified second sources for the onsemi FDD5614P are the AOD409 (Alpha & Omega Semiconductor Inc.) and the AOD407 (Alpha & Omega Semiconductor Inc.), out of 5 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the FDD5614P are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The FDD5614P (onsemi) is a part in the Transistors category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
