AI Summary

2N1893 by STMicroelectronics: Bipolar (BJT) Transistor NPN 80 V 500 mA 70MHz 800 mW Through Hole TO-39.

This active part from Microchip is a standard 2N3019 that acts as a robust electrical upgrade for the 2N1893. It supports double the continuous collector current and provides higher voltage breakdown headroom in an identical TO-39 physical footprint. It is ideal for applications demanding extra reliability or facing transient overcurrents.

  • Higher continuous collector current rating of 1A
  • Increased collector-base breakdown voltage (140V)
  • Active and supported high-reliability line
  • Slightly higher saturation voltage at high collector currents

The 2N3019 is a high-performance NPN transistor variant that serves as an excellent upgrade alternative to the 2N1893. It maintains the identical TO-39 package pinout while expanding the maximum continuous current capacity to 1A and raising the collector-base breakdown voltage to 140V. This device offers a higher safety headroom for inductive load switching and amplifier circuits.

  • Upgraded collector current capacity (1A vs 500mA)
  • Higher collector-base voltage (140V vs 120V) for improved safety margin
  • Common and widely stocked alternative
  • Slightly higher saturation voltage at elevated currents

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.
