FFF CompatibilityShares the exact same TO-92-3 footprint and Emitter-Base-Collector (E-B-C) pinout assignment.Uses the identical standard TO-92 through-hole plastic package form factor.Matches all electrical characteristics, including current, voltage, gain, power dissipation, and transition frequency.Surface-mount SOT-23 package is physically incompatible with a through-hole TO-92 footprint.Surface-mount package vs through-hole original.Replicates all critical electrical limits and gain specifications of the through-hole MPSA14.
AI Summary

MPSA14 by onsemi: Bipolar (BJT) Transistor NPN - Darlington 30 V 500 mA 125MHz 625 mW Through Hole TO-92 (TO-226).

This is an active, exact direct-replacement part produced by Central Semiconductor. It offers identical electrical parameters and pinout, making it a perfect drop-in replacement without any design modifications.

  • Direct drop-in replacement with exact same part number, package, and footprint
  • Identical maximum collector current of 500 mA and 30 V breakdown voltage
  • Maintains the high minimum DC current gain of 20,000 @ 100 mA

For modern redesigns where through-hole parts are being phased out, this surface-mount SOT-23 version of the MPSA14 provides the exact same electrical performance in an active SMD package.

  • Active SOT-23 surface-mount package for modern automated assembly lines
  • Same continuous collector current rating of 500 mA and 30 V breakdown voltage
  • Identical minimum DC current gain of 20,000 @ 100 mA
  • Requires PCB redesign to convert the through-hole TO-92 footprint to SOT-23 surface-mount layout

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.
