FFF CompatibilityEmploys the same DirectFET MZ footprint and pin configuration, fitting directly onto the existing PCB layout.Matches the physical shape, package thickness, and dual-sided thermal dissipation interface of the original.The maximum on-resistance is higher (16.5 mOhm vs 11 mOhm) and input capacitance is larger (2800 pF vs 1350 pF), which affects switching and conduction efficiency.Uses the identical DirectFET MZ package outline and pad layout, allowing it to be soldered directly to the existing PCB layout with zero modifications.Matches the DirectFET MZ mechanical dimensions and dual-sided cooling capabilities exactly.Has a higher maximum on-resistance (15 mOhm vs 11 mOhm), which will increase conduction losses under the same current load.
AI Summary

IRF6674TR1PBF by Infineon Technologies: N-Channel 60 V 13.4A (Ta), 67A (Tc) 3.6W (Ta), 89W (Tc) Surface Mount DIRECTFET™ MZ.

A 150V N-channel OptiMOS device in the same DirectFET MZ package. It provides an active drop-in option with excellent voltage margin, though it compromises on on-resistance.

  • Direct pin-compatible drop-in replacement package
  • Significantly higher voltage headroom (150V vs 60V) for high-voltage spikes
  • Active lifecycle status compared to the obsolete original part
  • Higher RDS(on) (16.5 mOhm vs 11 mOhm max) increases conduction losses
  • Larger gate charge and input capacitance increase switching loss and require more robust gate-driver current

An 80V N-channel MOSFET in the identical DirectFET MZ package. It is a direct drop-in alternative for legacy support, although it has slightly higher on-resistance.

  • Direct pin-compatible drop-in replacement package
  • Higher drain-to-source breakdown voltage (80V vs 60V)
  • Similar gate charge (31 nC vs 36 nC max) allowing similar driver performance
  • Higher RDS(on) (15 mOhm vs 11 mOhm max) leading to increased thermal dissipation under load
  • Also obsolete, meaning it only serves as a short-term legacy replacement rather than a long-term design path

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.
