TPHR8504PL,LQ(M1W
TOSHIBA
Needs validationmedium risk
TPHR8504PL is a stronger 40V SOP Advance MOSFET, but gate charge and pinout need review.
Best Alternatives to TPH1R403NL
TPH1R403NL is a 30V high-current SOP Advance N-channel MOSFET. Alternatives need pinout, SOA and gate-drive review.
AI replacement insight
Electrical riskmedium
Qg, Rds and SOA vary.
Package riskmedium
Package matches do not prove pinout.
Firmware risklow
Discrete MOSFET.
Sourcing riskmedium
Lifecycle data is limited.
Can it be replaced directly?
No pin-compatible replacement is verified from the provided data.
Best replacement path
TPHR8504PL is the strongest catalog candidate, pending pinout and gate-drive checks.
