Is there a pin-compatible replacement for KM228M035K25RR0VH2FP0?

No replacement has been fully verified as pin-compatible without manual review. ERF1VM222L25OT appears to be a form-fit match, including package size and lead spacing, making it the most likely candidate for a pin-compatible replacement after datasheet verification.

What risks should I check before replacing KM228M035K25RR0VH2FP0?

Before replacing, you must check three main risks: 1) Physical Fit: Ensure the candidate's diameter, length, and lead spacing match your board. 2) Electrical Specs: Verify that the ESR and ripple current ratings are suitable for your application. 3) Voltage: While higher voltage is safe, ensure it's not excessively high for cost reasons.
