Best Alternatives to AP2300

Package: SOT-23ALLPOWERMOSFETs - SingleFET Type: N-ChannelDrain-Source Voltage (Vdss): 20 VContinuous Drain Current (Id): 5.2 ARDS(on) (Max) @ Id, Vgs: 25 mΩ @ 6A, 4.5VVgs(th) (Max) @ Id: 1.5 V @ 250µA

AP2300 is a 20V SOT-23 N-channel MOSFET. Alternatives need pinout, voltage margin, current, and RDS(on) checks.

AI replacement insight

Electrical riskmedium

RDS, current, and voltage margin differ.

Package riskmedium

SOT-23 matches, pinout is missing.

Firmware risklow

Discrete MOSFET; no firmware impact shown.

Sourcing riskmedium

Lifecycle varies by candidate.

Can it be replaced directly?

No verified pin-compatible AP2300 replacement is proven from the provided fields.

Best replacement path

Review SI2300 first for relaxed electrical use; review IRLML2502 only for lower-current loads.

Main risk

Unverified pinout plus higher loss or lower current.
