| FFF Compatibility | The pinout is exactly 1-Emitter, 2-Base, 3-Collector in a TO-92-3 package, matching the original layout.Standard through-hole TO-92 package with identical physical dimensions and mounting style.Meets or exceeds all electrical ratings (30V breakdown, 500mA collector current, 625mW power dissipation, 20k gain). | Identical 1-Emitter, 2-Base, 3-Collector pinout in a TO-92 package.Matches the physical package dimensions and mounting of the obsolete part.The minimum DC current gain (hFE) is 10,000 at 100mA, which is lower than the original's 20,000 limit. | ||
 AI Summary | MPSA14 by onsemi: Bipolar (BJT) Transistor NPN - Darlington 30 V 500 mA 125MHz 625 mW Through Hole TO-92 (TO-226). | This is an active, exact replacement manufactured by Central Semiconductor. It offers 100% compatibility in Fit, Form, and Function with the same high-gain Darlington performance and pin configuration.
| A sibling part from the same onsemi family that remains active. It is a drop-in match but features a lower minimum current gain (10,000 versus 20,000) than the original MPSA14.

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 MPSA14 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 MPSA14 are the MPSA14 PBFREE (Central Semiconductor) and the KSP13BU (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 MPSA14 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 MPSA14 (onsemi) is a part in the Transistors category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
