Is there a pin-compatible replacement for KM228M016G20RR0VH2FP0?

No exact pin-compatible replacement was found in this review. The closest option, EWH1EM222K20OT, has matching lead spacing but is physically wider. Other functional alternatives require a full board redesign due to different package sizes and lead spacing.

What risks should I check before replacing KM228M016G20RR0VH2FP0?

Before replacing, you must check three main risks: 1) Package Size: Verify the new part fits on your PCB, as most alternatives are larger. 2) Lead Spacing: Ensure the pin pitch matches your board's drill holes. 3) Electrical Parameters: While higher voltage is generally safe, confirm it has no unintended effects in your specific circuit.

AI replacement insight

Electrical risklow

All suggested alternatives have equal or higher voltage ratings, which is safe.

Package riskhigh

Most candidates are physically much larger. Even the best option has a larger diameter requiring clearance verification.

Can it be replaced directly?

No direct, drop-in replacement with identical form, fit, and function was found. The closest candidate, EWH1EM222K20OT, has a larger diameter that requires verification.

Best replacement path

Upgrade to EWH1EM222K20OT, which offers a higher voltage rating and matches lead spacing, but requires verifying the 3mm larger diameter fits the PCB layout.

Main risk

The primary risk is physical incompatibility. Most alternatives are significantly larger and have different lead spacing, requiring a board redesign.

Recommended alternatives

A strong alternative with matching capacitance, lead spacing, and higher voltage, but a slightly larger diameter.
