SI4401FDY-T1-GE3 is a stronger P-channel SO-8 MOSFET candidate pending pinout review.
IRF7416TRPBF is a -30 V, -10 A P-channel SO-8 MOSFET. Available candidates need pinout and stress checks before substitution.
Check Vds margin, Id, Rds, Qg, SOA.
SO-8 matches, but pinout is unknown.
Discrete MOSFET; no firmware interface.
Lifecycle varies by candidate.
No pin-compatible replacement is confirmed from the provided evidence.
Review SI4401FDY-T1-GE3 first; it has stronger voltage, current, and Rds ratings.
Pinout is not provided for the candidates.

| Feature / factor | IRF7416TRPBF | SI4401FDY-T1-GE3 | AO4407C | SI4435DYTRPBF | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SO-8 | SO-8 | SO-8 | SO-8 | SO-8 — same package; AO4407C: same package; SI4435DYTRPBF: same package |
| Pinout | 8-pin required | 8-pin only | 8-pin only | 8-pin only | 8-pin only — pin map missing; AO4407C: pin map missing; SI4435DYTRPBF: pin map missing |
| Voltage | -30 V | -40 V | -30 V | -30 V | -40 V / -30 V — meets 1.1x; AO4407C: no 1.1x margin; SI4435DYTRPBF: no 1.1x margin |
| Current | -10 A | -14 A | -14 A | -8 A | -14 A / -8 A — higher Id; AO4407C: higher Id; SI4435DYTRPBF: lower Id |
| Resistance | 20 mΩ | 14.2 mΩ | 11.5 mΩ | 20 mΩ | 14.2 mΩ / 11.5 mΩ / 20 mΩ — lower Rds; AO4407C: lower Rds; SI4435DYTRPBF: similar Rds |
SI4401FDY-T1-GE3 is the strongest candidate here, but pinout and thermal checks are still required.
