Is there a pin-compatible replacement for MBR130T1G?

Yes, several parts like SL02-GS08-FS and RB160M-60 are available in the same SOD-123 package and are considered pin-compatible. However, you must review their electrical parameters to ensure they are suitable for your application.

What risks should I check before replacing MBR130T1G?

Before replacing MBR130T1G, you must check two key parameters: forward voltage (Vf) and reverse leakage current (Ir). A higher Vf increases power dissipation and heat. A higher Ir increases standby power consumption and can affect sensitive circuits.

MBR130T1G Alternatives, Datasheet & Cross Reference | onsemi

The onsemi MBR130T1G is a 1A, 30V Schottky rectifier in a compact SOD-123 package, valued for its low forward voltage. Finding a substitute requires careful balancing of electrical trade-offs, primarily between forward voltage and reverse leakage current.

AI replacement insight

Electrical riskmedium

Candidates have trade-offs in forward voltage (Vf) and reverse leakage (Ir) that affect efficiency and power consumption.

Package risklow

Multiple candidates are available in the same SOD-123 package, ensuring form-fit compatibility.

Can it be replaced directly?

No direct drop-in replacement is confirmed. Several parts like RB160M-60 and SL02-GS08-FS are form-fit compatible in the SOD-123 package but have different electrical trade-offs requiring engineering review.

Best replacement path

RB160M-60 offers a balanced profile with a higher voltage rating and manageable reverse leakage, despite a higher forward voltage. For applications sensitive to forward voltage, SL02-GS08-FS is better but has very high leakage.

Main risk

The primary risk is choosing between a part with higher forward voltage (more power loss) or one with significantly higher reverse leakage current (more standby power loss).

Recommended alternatives

A form-fit alternate with higher voltage rating, but has higher forward voltage and reverse leakage.
