Best Alternatives to RK7002BM

Package: SOT-23TECH PUBLICMOSFETs - SingleDrain-Source Voltage (Vdss): 60 VContinuous Drain Current (Id): 0.3 ARDS(on) (Max) @ Id, Vgs: 2.2 Ohm @ 300mA, 10VVgs(th) (Max) @ Id: 1.6 V @ 250uAInput Capacitance (Ciss) @ Vds: 27 pF @ 30V

RK7002BM is a 60V, 300mA N-Channel MOSFET in a SOT-23 package. Key alternatives exist with similar or improved performance, but require careful review of on-resistance (RDS(on)) and gate threshold voltage (Vgs(th)).

AI replacement insight

Electrical riskmedium

Vgs(th) and RDS(on) vary between candidates and must be checked against application requirements.

Package risklow

All candidates use the SOT-23 package, but pinout must be verified to ensure compatibility.

Can it be replaced directly?

Direct replacement for RK7002BM should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

T2N7002AK-ES offers the most balanced profile with improved RDS(on) and matching key parameters.

Main risk

The main risk is mismatch in gate threshold voltage (Vgs(th)), which could prevent the MOSFET from turning on correctly with existing drive circuitry.
