RB161M-20TR is a 20V, 1A Schottky diode in a SOD-123 package from ROHM, now marked as NRND. Alternatives exist within the ROHM family, but require checking the impact of a higher forward voltage on efficiency.

AI replacement insight

Electrical riskmedium

Higher forward voltage (Vf) in all candidates will increase power loss and heat. Must be verified.

Package risklow

Candidates share the same SOD-123 package, ensuring form-fit compatibility.

Sourcing riskmedium

The target and all close alternatives are marked NRND, indicating potential long-term supply issues.

Can it be replaced directly?

No direct drop-in replacement is confirmed. Several ROHM parts like RB160M-30TR are form-fit compatible but have a higher forward voltage, requiring design review.

Best replacement path

Consider ROHM's RB060M-30TR for higher voltage/current ratings, but verify the impact of its higher forward voltage.

Main risk

The primary risk is increased power dissipation and reduced efficiency due to higher forward voltage in all viable alternatives.
