Finding a replacement for the K26 Schottky diode involves matching its 60V, 2A rating and SOD-123FL package. Key alternatives exist with similar or improved electrical characteristics, requiring careful review of forward voltage and operating margins.

AI replacement insight

Electrical riskmedium

Vf mismatch or lack of voltage/current margin in some candidates requires review.

Package risklow

SOD-123FL is a standard package with multiple sources.

Sourcing risklow

Multiple viable alternatives from different manufacturers are available.

Can it be replaced directly?

Direct replacement for K26 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

DSK26 offers the most direct parametric match, while parts like DSS310 provide higher ratings at the cost of a slightly higher forward voltage.

Main risk

The main risk is functional mismatch; ensure the replacement is a Schottky diode, not a fast-recovery type. Also, check forward voltage (Vf) to avoid increased power dissipation.
