| FFF Compatibility | Identical SOT-23-3 physical package footprint, but the original STMicroelectronics datasheet specifies an Emitter-Base-Collector (1-2-3) pinout while the onsemi part utilizes a standard Base-Emitter-Collector (1-2-3) pinout.Matches the physical SOT-23-3 (TO-236AB) surface-mount package shape and dimensions exactly.Maximum power dissipation rating is slightly lower (300 mW vs 350 mW of the original). | Identical SOT-23-3 physical footprint, but the STMicroelectronics datasheet designates an Emitter-Base-Collector layout whereas the onsemi part utilizes a Base-Emitter-Collector layout.Matches the physical SOT-23-3 package shape and dimensions exactly.Maximum power dissipation rating is slightly lower (300 mW vs 350 mW of the original). | ||
 AI Summary | MMBT2907A by STMicroelectronics: Bipolar (BJT) Transistor PNP 60 V 600 mA 200MHz 350 mW Surface Mount SOT-23-3. | An active, widely-supported direct industry replacement from onsemi. It matches all core electrical voltage, current, and frequency ratings of the obsolete STMicroelectronics device. However, it exhibits a slightly lower power dissipation ceiling of 300 mW compared to the original's 350 mW.
| The automotive-grade equivalent to the MMBT2907ALT1G, carrying AEC-Q101 qualification. It provides high durability and identical electrical specs to the standard onsemi part, but shares the slightly lower 300 mW power dissipation limit.

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 STMicroelectronics MMBT2907A 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 STMicroelectronics MMBT2907A are the MMBT2907ALT1G (onsemi) and the SMMBT2907ALT1G (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 MMBT2907A 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 MMBT2907A (STMicroelectronics) is a part in the Transistors category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
