Is there a pin-compatible replacement for KM477M035G17RR0VH2FP0?

No, a verified pin-compatible replacement is not available. The closest candidates have different lead spacing or are a different mounting type (SMD) altogether, requiring a board redesign.

What risks should I check before replacing KM477M035G17RR0VH2FP0?

The main risk is mechanical. You must check the package size, mounting type (Radial vs. SMD), and lead spacing. Also, verify secondary electrical parameters like ESR and ripple current if your application is sensitive.

KM477M035G17RR0VH2FP0 Alternatives, Datasheet & Cross Reference | Chengx

Finding a substitute for the CX KM477M035G17RR0VH2FP0, a 470µF 35V radial capacitor, requires careful review of mechanical specifications. While functional alternatives exist, no direct drop-in replacements have been identified, and a board modification may be necessary.

AI replacement insight

Package riskhigh

No candidates match the target's package dimensions and lead spacing. A board redesign is likely required.

Electrical risklow

Candidates with matching or superior primary electrical specs (capacitance, voltage) are available.

Can it be replaced directly?

No direct, pin-for-pin compatible replacement has been verified. All reviewed candidates have different physical dimensions, lead spacing, or mounting types.

Best replacement path

Evaluate functional alternatives that require board layout changes, such as smaller radial parts or surface-mount (SMD) equivalents, after confirming mechanical fit.

Main risk

The primary risk is mechanical incompatibility. The target is a 10x17mm radial capacitor with 5mm lead spacing, and all known alternatives have a different footprint.

Recommended alternatives

Functionally similar radial capacitor but with a smaller package and different lead spacing, requiring board verification.
