AI Summary

MMBT2222A by onsemi: Bipolar (BJT) Transistor NPN 40 V 600 mA 300MHz 300 mW Surface Mount SOT-23.

The MMBT2222A-7-F is an active, highly reliable direct drop-in replacement from Diodes Incorporated. It matches the original package footprint and pinout exactly, while offering a slightly higher maximum power dissipation rating of 310 mW. All other critical electrical specifications are fully equivalent.

  • Direct drop-in replacement with exact physical matching
  • Slightly higher power dissipation rating: 310 mW vs 300 mW
  • Produced by a highly reliable, Tier-1 semiconductor manufacturer

The MMBT2222A-TP from MCC is an active, widely available alternative that serves as a direct drop-in replacement. It offers a superior power dissipation limit of 350 mW while maintaining identical voltage, current, and speed specifications.

  • Direct drop-in replacement footprint and standard pinout
  • Higher power dissipation rating of 350 mW compared to the original 300 mW

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 MMBT2222A 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.
