Is there a pin-compatible replacement for DB107S-T?

Yes, DB207S-T is a likely pin-compatible replacement. It shares the same DBS package and pin count. The industry-standard DB207S is also a strong candidate for form, fit, and function, but pinout should always be verified from the datasheet before assembly.

What risks should I check before replacing DB107S-T?

Before replacing DB107S-T, first verify the package and pinout. While parts like DB207S are likely compatible, functional alternates in different packages (TMBF, TTF) will require a PCB redesign. Also, check for minor parametric differences like reverse leakage current.

DB107S-T Alternatives, Datasheet & Cross Reference | GOODWORK

DB107S-T is a standard 1A, 1000V surface-mount bridge rectifier in a DBS package. Excellent upgrade paths like the DB207S-T offer higher current handling in the same footprint, while other functional alternatives are available if a PCB redesign is possible.

AI replacement insight

Electrical risklow

Most candidates offer stronger electrical specs. A few have slightly higher reverse leakage, which is a minor risk.

Package riskhigh

Several functional alternates exist in different packages (TMBF, TTF, MSB) that are not drop-in compatible.

Can it be replaced directly?

Yes, DB207S-T is a likely direct replacement for DB107S-T, offering double the current handling in the same package. DB207S from other vendors is also a strong form-fit-function candidate.

Best replacement path

The best replacement path is DB207S-T, which offers a higher 2A current rating in the same package from the same manufacturer, making it a robust upgrade.

Main risk

The main risk when substituting is selecting a part with a different package (e.g., TMBF, TTF, MSB), which would require a PCB redesign.

Recommended alternatives

A 2A upgrade in the same DBS package from the same manufacturer, likely pin-compatible.
