What risks should I check before replacing X2P2104KQ1B0180120060ES0?

First, confirm the lead pitch is 15mm, as many similar parts use a different pitch. Second, check the capacitor's physical case dimensions (length, height, thickness) to ensure it fits on your PCB.

Find pin-compatible and upgrade path replacements for the STE X2P2104KQ1B0180120060ES0 film capacitor. Key alternatives offer higher voltage or safety class ratings with the same 15mm lead pitch.

AI replacement insight

Electrical risklow

Kept candidates match or exceed key electrical specifications.

Package riskmedium

Lead pitch matches, but full case dimensions must be verified from datasheets to ensure fit.

Can it be replaced directly?

Direct replacement for X2P2104KQ1B0180120060ES0 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

C42Q2104K6SC000 from Faratronic is a strong pin-to-pin match. MP1104K44D2R8LC from SRD is an upgrade path with higher ratings.

Main risk

The main risk is physical incompatibility. Several alternatives have the wrong lead pitch (10mm vs 15mm). Always verify lead pitch and case dimensions.

Recommended alternatives

A pin-compatible alternative with a matching safety class (X2) and slightly higher voltage rating (305V).
