Is there a pin-compatible replacement for K14?

Yes, K24 and DSK24 are pin-compatible replacements for K14. They are all 2-pin Schottky diodes in the same SOD-123FL surface-mount package.

What risks should I check before replacing K14?

Before replacing K14, verify that the substitute's forward voltage (Vf) and reverse leakage current (Ir) are acceptable for your circuit, especially in power-sensitive or high-temperature applications.

K14 Alternatives, Datasheet & Cross Reference | GOODWORK

AI replacement insight

Electrical risklow

Candidates have equal or better voltage/current ratings. Vf is different and requires review.

Package risklow

All recommended parts use the identical SOD-123FL package.

Can it be replaced directly?

Yes, K24 and DSK24 are strong candidates for replacing K14. They share the same package, voltage rating, and diode type, with an improved current rating.

Best replacement path

Use K24 or DSK24. Both are Schottky diodes in the same package with a higher 2A current rating, offering a direct upgrade path.

Main risk

The primary risk is a potential mismatch in dynamic characteristics like forward voltage (Vf) and reverse leakage current (Ir), which should be verified.

Recommended alternatives

A pin-compatible Schottky diode in the same package with a higher current rating.
