Is there a pin-compatible replacement for KM477M050G20RR0VH2FP0?

Yes, AISHI ERS1HM471G20OT and ROQANG KM1H471M1020 are considered pin-compatible replacements. They share the same 470µF capacitance, 50V rating, and 10x20mm radial through-hole package.

What risks should I check before replacing KM477M050G20RR0VH2FP0?

Before replacing, verify the package dimensions and mounting type. While some parts are pin-compatible, others may be larger or use surface-mount technology (SMD). Also, check secondary parameters like ESR and ripple current from the datasheet to ensure performance in your specific application.
