Needs validationmedium risk
IRLML2502 is a close N-channel SOT-23 option with lower RDS(on).
Best Alternatives to AP2302B
AP2302B is a 20V N-channel SOT-23 MOSFET. Alternatives need pinout, VDS margin, and RDS(on) checks.
AI replacement insight
Electrical riskmedium
VDS margin or RDS(on) may differ.
Package riskmedium
SOT-23 matches, pinout is missing.
Firmware risklow
Discrete MOSFET, no firmware.
Sourcing riskmedium
Lifecycle data is incomplete.
Can it be replaced directly?
No confirmed pin-compatible replacement is proven from the provided fields.
Best replacement path
Start with IRLML2502 or SI2300, then verify pinout.
Main risk
Pinout is not verified and some options lack voltage margin.
