AI Summary

MJE253 by onsemi: Bipolar Transistors - BJT 4A 100V 15W PNP.

The MJE253G is the direct, Pb-free, active successor to the obsolete MJE253, manufactured by onsemi. It offers identical electrical performance and mechanical form factor, serving as a true seamless replacement.

  • Official direct replacement from same manufacturer
  • Pb-free and RoHS compliant version
  • Perfect drop-in footprint and pinout compatibility

The 2SB1168S is a high-performance PNP transistor in a matching TO-126 package, offering identical voltage and current limits. It features an upgraded transition frequency of 130 MHz, making it ideal for high-speed switching and audio driver stages.

  • Same TO-126 package and pinout format
  • Higher transition frequency (130 MHz vs 40 MHz) for improved transient performance
  • Excellent alternative source (originally Sanyo, now Rochester/onsemi)
  • Power dissipation limits vary slightly depending on heatsinking profile

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 MJE253 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.
