Is there a pin-compatible replacement for EWH1VM471G13OT?

While KNH2470UF35V149EC0017 shares the same radial package, its different capacitor technology (polymer) means it is not a simple pin-to-pin replacement and requires engineering review.

What risks should I check before replacing EWH1VM471G13OT?

Key risks include mismatched capacitance, which can affect circuit operation, and differences in capacitor technology (e.g., polymer vs. standard electrolytic), which changes ESR and ripple current ratings. Always verify package dimensions and lead spacing.
