Is there a pin-compatible replacement for MPP105J2W10KN22605?

Based on this review, no pin-compatible (10mm lead pitch) replacements were identified. All viable electrical alternatives require physical modification for installation.

What risks should I check before replacing MPP105J2W10KN22605?

Key risks include package mismatch (lead pitch), tolerance differences (e.g., ±10% vs ±5%), and potential changes in electrical characteristics if using a safety-rated capacitor (X2) where not required. Always verify the candidate's datasheet.

AI replacement insight

Package riskhigh

Lead pitch mismatch requires board redesign.

Electrical risklow

Functional alternates have superior voltage ratings.

Can it be replaced directly?

No direct, pin-compatible replacement was found in this analysis. All candidates with suitable electrical ratings have a different physical package.

Best replacement path

Search for a 1uF, >=450VDC film capacitor with a 10mm radial lead pitch.

Main risk

The primary risk is physical incompatibility; all electrically suitable candidates have a much larger lead pitch (22.5mm vs 10mm).

Recommended alternatives

Functional alternative with a higher voltage rating but a larger lead pitch requiring board redesign.
