| FFF Compatibility | Standard SOT-23 package with identical 1-Base, 2-Emitter, 3-Collector pinout configuration.Identical SOT-23 package dimensions and footprint, allowing direct assembly on the existing land pattern.The electrical characteristics completely match or exceed the original obsolete part specs, including Vce=45V and Ic=100mA. | Standard SOT-23-3 (TO-236) package with identical 1-Base, 2-Emitter, 3-Collector pin layout.Standard SOT-23 mechanical dimensions matching the target part footprint.Matches critical electrical ratings (Vce=45V, Ic=100mA, hFE=420 min) and offers a superior 300mW power handling rating. | ||
 AI Summary | BC847C by onsemi: Bipolar (BJT) Transistor NPN 45 V 100 mA 100MHz 200 mW Surface Mount SOT-23. | This is the direct modern successor and active replacement from Taiwan Semiconductor Corporation. It updates the obsolete base part to a fully green, RoHS-compliant, and halogen-free specification while maintaining exact electrical and physical drop-in compatibility.
| This is an industry-standard second-source replacement from onsemi. It offers identical pinout and electrical specifications with a higher maximum power dissipation rating of 300 mW, which provides extra thermal safety margin.

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 BC847C 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 BC847C are the BC847C RFG (Taiwan Semiconductor Corporation) and the BC847CLT1G (onsemi), out of 6 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 BC847C 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 BC847C (onsemi) is a part in the Transistors category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
