FFF CompatibilityShares the exact standard SOT-23 pinout (Pin 1: Base, Pin 2: Emitter, Pin 3: Collector) as verified by datasheet extraction.Housed in the identical SOT-23 (TO-236AB) surface-mount package.Matches the key electrical characteristics including a 45 V VCEO breakdown, 100 mA collector current limit, and the identical hFE gain class 'B' (200 to 450).Utilizes the identical SOT-23-3 pin assignment with Pin 1 as Base, Pin 2 as Emitter, and Pin 3 as Collector.Fits the exact same SOT-23 package footprint on the PCB.Meets the same 45 V breakdown and 100 mA current limit with matching gain class specifications.
AI Summary

BC847B by MULTICOMP PRO: Bipolar (BJT) Single Transistor, NPN, 45 V, 100 mA, 250 mW, SOT 23, Surface Mount.

The Nexperia BC847B,215 is a standard industry-wide second source that matches the Multicomp Pro device in form, fit, and electrical capabilities. It serves as an optimal first-choice replacement.

  • True drop-in replacement with identical SOT-23 pin configuration
  • Highly reliable and widely available general-purpose transistor from a tier-1 semiconductor manufacturer
  • Low collector cutoff current (15 nA max) matches the original performance

The Diodes Incorporated BC847B-7-F is an excellent alternative that offers a higher power rating and a faster transition frequency while maintaining exact drop-in equivalence.

  • Drop-in pin-to-pin SOT-23 compatibility
  • Higher transition frequency (300 MHz) compared to the original 100 MHz for better high-speed switching performance
  • Higher power dissipation capability (300 mW vs. 250 mW) provides improved thermal margin

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.
