| FFF Compatibility | Pin-compatible dual NPN array in the exact same SOT-363 package.Standard SOT-363 surface-mount package with identical dimensions and lead pitches.Matches all critical electrical ratings, including V_CEO of 45V, I_C of 100mA, and DC gain range. | Fully pin-compatible footprint in SOT-363 / SC-88. (Note: Transistor numbering T1 and T2 is internally swapped relative to the original, but the respective E, B, and C pins map to the identical external package pins).Identical SC-88/SOT-363 dimensions and lead pitch.Meets or exceeds all electrical parameters, providing upgraded power dissipation handling of 380mW. | ||
 AI Summary | BC847S by onsemi: Bipolar (BJT) Transistor Array 2 NPN (Dual) 45V 200mA 200MHz 300mW Surface Mount SC-88 (SC-70-6). | This is a direct, active drop-in replacement with the exact same manufacturer part number and package form factor from Diotec Semiconductor. It maintains identical electrical, thermal, and footprint compatibility to ease supply chain migration.
| This is onsemi's modern active replacement for the obsolete BC847S. It provides a significant power dissipation upgrade to 380mW while keeping the exact same physical package, pin positions, and electrical characteristics.

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 BC847S 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 BC847S are the BC847S (Diotec Semiconductor) and the BC847BDW1T1G (onsemi), out of 7 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 BC847S 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 BC847S (onsemi) is a part in the Transistors category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
