Is there a pin-compatible replacement for RB160M-30?

Several parts like SL14D and SS36FA use the same SOD-123 package and are likely pin-compatible. However, pin-to-pin functionality must be confirmed by reviewing datasheets as electrical parameters like reverse leakage differ.

What risks should I check before replacing RB160M-30?

Key risks are: 1) Higher forward voltage (Vf) increasing power loss. 2) Higher reverse leakage current (Ir) impacting low-power performance. 3) Package variations like SOD-123 vs SOD-123FL affecting PCB layout.

RB160M-30 Alternatives, Datasheet & Cross Reference | KEXIN

RB160M-30 is a 30V, 1A Schottky diode in a SOD-123 package, valued for its low 0.48V forward voltage. Finding a substitute requires matching the package and ensuring forward voltage and reverse leakage meet application needs.

AI replacement insight

Electrical riskmedium

Forward voltage and reverse leakage can vary significantly between parts.

Package risklow

Most candidates are SOD-123, but variations like SOD-123FL exist and require layout check.

Can it be replaced directly?

No verified direct drop-in replacement is available. SL14D is a strong functional alternative, but requires engineering review of its higher reverse leakage current.

Best replacement path

SL14D offers a similar profile with improved forward voltage, but its higher reverse leakage must be checked.

Main risk

The primary risk is substituting with a part that has higher forward voltage (Vf), increasing power loss, or higher reverse leakage (Ir), affecting efficiency.

Recommended alternatives

A form-fit alternate in a SOD-123 package with higher voltage (40V) and lower forward voltage, but higher reverse leakage.
