Is there a pin-compatible replacement for KM478M016J25RR0VH2FP0?

No pin-to-pin compatible replacements have been identified. All suitable functional alternatives require verification of physical dimensions (diameter, height, and lead spacing) before use.

What risks should I check before replacing KM478M016J25RR0VH2FP0?

The main risks are physical. All candidates are larger in diameter or height and may have different lead spacing, requiring PCB layout verification. Ensure any replacement has an equal or higher voltage rating.

AI replacement insight

Package riskhigh

All candidates are larger in diameter and/or height, with different lead spacing.

Electrical risklow

Kept candidates match capacitance and have a higher (safer) voltage rating.

Sourcing riskmedium

Alternatives require careful spec validation before procurement.

Can it be replaced directly?

No direct drop-in replacement is available; all functional candidates have different physical dimensions that must be verified.

Best replacement path

The most promising path is KM478M025K25RR0VH2FP0, an upgrade in voltage from the same series, but requires careful physical verification.

Main risk

The primary risk is package incompatibility; all functional alternatives are physically larger than the target part and require layout verification.

Recommended alternatives

A functional upgrade with a higher voltage rating, but requires physical layout verification due to a larger diameter.
