FFF CompatibilityIdentical package footprint and pin assignments (1: Emitter, 2: Collector, 3: Base).Same TO-225/TO-126 package form factor and mechanical dimensions.Direct lead-free transition of the same series with identical electrical parameters.Requires layout redesign due to surface-mount (SMD) mounting and a different pin assignment (1: Base, 2/4: Collector, 3: Emitter).Surface-mount DPAK (TO-252) package instead of a through-hole TO-225/TO-126 package.Matches the electrical specifications exactly, including the 100V and 4A ratings.
AI Summary

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

The MJE253G is the direct lead-free (Pb-free) drop-in equivalent to the MJE253. It maintains identical electrical and physical characteristics, providing a seamless and direct replacement.

  • Direct drop-in replacement with identical pinout and footprint
  • Pb-free and RoHS compliant version of the target part
  • Identical electrical specifications across all maximum ratings and characteristics

The MJD253T4G is the active surface-mount DPAK version of the MJE253 series. While it is physically incompatible due to the SMD footprint and different pinout order, it provides an electrically identical solution for board redesigns.

  • Exact electrical matches since it belongs to the same silicon family (MJD253)
  • Highly active and widely available surface-mount component
  • Requires a redesign of the PCB land pattern to accommodate the surface-mount package
  • Pinout sequence is shifted from E-C-B to B-C-E

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.
