SSM3J328R,LF is an active Toshiba P-channel MOSFET. No reviewed candidate is a verified pin-compatible replacement.

AI replacement insight

Electrical riskhigh

Vdss or current/Rds differs.

Package riskmedium

Package matches, pinout not verified.

Firmware risklow

Discrete MOSFET, no firmware.

Sourcing risklow

Kept Toshiba parts are Active.

Can it be replaced directly?

Direct replacement for SSM3J328R,LF should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Use SSM3J338R only for low-voltage rails; use SSM3J351R only for lighter loads.

Main risk

Electrical ratings and unverified pinout.
