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.

  • Direct drop-in replacement from the original manufacturer (Taiwan Semiconductor)
  • Active lifecycle status ensuring long-term supply security
  • Identical 45V Vce, 100mA Ic, and high gain (420-800 hFE) ratings

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.

  • Industry-standard general purpose transistor from a premier supplier (onsemi)
  • Higher power dissipation rating of 300 mW compared to the original 200 mW
  • Highly active lifecycle status with excellent distributor stock availability

You searched one part. Parter watches your whole BOM.

  1. 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.

  2. 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.

  3. 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.
