FFF CompatibilityUses the standard 1: Gate, 2: Source, 3: Drain assignment on a 3-pin SOT-323 layout matching the original.Packaged in SOT-323 (SC-70), which mounts directly onto the original MCPH3 footprint.Meets or exceeds all critical electrical characteristics including 20V breakdown and ±12V gate voltage handling.Matches the exact 3-pin assignment (1: Gate, 2: Source, 3: Drain) and has the standard SOT-323 footprint which is compatible with the original MCPH3 landing pattern.The SOT-323 (SC-70) package shares the same package dimensions, pin pitch (0.65mm), and mounting style as the original MCPH3.Maintains the 20V drain-to-source rating and ±12V gate-to-source rating while improving the current and on-resistance parameters.
AI Summary

MCH3476-TL-H by onsemi: N-Channel 20 V 2A (Ta) 800mW (Ta) Surface Mount SC-70FL/MCPH3.

An excellent drop-in option that provides improved thermal and power performance over the obsolete onsemi device. It features a lower on-resistance and higher continuous drain current rating.

  • Fully pin-compatible drop-in with matching SOT-323 package.
  • Higher continuous drain current capacity: 2.8A vs 2.0A.
  • Lower on-resistance: 56 mΩ vs 125 mΩ @ 4.5V.

This is a high-performance, active alternative from Diodes Incorporated that serves as a drop-in replacement. It offers a massive upgrade in continuous current capability and power efficiency due to its much lower on-resistance.

  • Pin-compatible standard drop-in with matching SOT-323/SC-70 footprint.
  • Higher continuous drain current capacity: 3.5A vs 2.0A.
  • Significantly lower on-resistance: 42 mΩ vs 125 mΩ @ 4.5V (reducing power losses).

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.
