IRLML6344TRPBF is a 30V N-channel SOT-23 MOSFET. Candidate replacements need pinout, RDS(on), and thermal checks.

AI replacement insight

Electrical riskmedium

Check RDS(on), Qg, SOA, and VDS margin.

Package riskmedium

SOT-23 matches, but pin functions are not shown.

Firmware risklow

Discrete MOSFET; no firmware interface.

Sourcing riskmedium

AO3400A has NRND catalog status.

Can it be replaced directly?

Direct replacement for IRLML6344TRPBF should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Review AO3480C first, then AO3400C; use AO3400A only with relaxed loss and lifecycle checks.

Main risk

Pinout is not verified for the kept candidates.
