 AI Summary | FPF2701MPX by onsemi: Power Switch/Driver 1:1 N-Channel 2A 8-MLP (3x3). | The FPF2702MPX is a same-family sibling in the identical MLP 3x3mm package with a matching pinout. The primary functional difference is that during an overcurrent condition, this device continuously clamps the output current in constant-current mode and pulls the FLAGB pin low, rather than latching off. This requires the host microcontroller or external circuitry to monitor FLAGB and manually toggle the ON pin for shutdown. Please note that like the queried part, this line has also been discontinued by onsemi.
| The FPF2700MPX is another direct drop-in sibling from the same obsolete Fairchild/onsemi AccuPower series, sharing the same physical footprint and pin layout. Rather than latching off on a fault like the FPF2701, the FPF2700 enters an auto-restart loop with a 0.5 ms blanking time and a 127.5 ms retry period. This part is a drop-in replacement but changes system fault recovery behavior and is also obsolete.

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 FPF2701MPX 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 FPF2701MPX are the FPF2702MPX (onsemi) and the FPF2700MPX (onsemi), 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 FPF2701MPX 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 FPF2701MPX (onsemi) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
