Safe identification

How to verify this result

1. Match the physical package

Compare the candidate package with the outline, pin count and polarity mark on the actual board.

2. Confirm the electrical fit

Check the official datasheet for pinout, voltage, current and thermal ratings—not only the marking.

3. Treat uncertainty as a stop signal

Do not treat a short marking, a low-confidence candidate or a family match as a drop-in replacement.
