Strong parametric match with identical safety class, voltage, capacitance, and 10mm lead pitch. Requires review.
Finding a replacement for the X2P2104KN1B0130120060ES0 Class X2 capacitor requires careful attention to the 10mm lead pitch. Several functional alternatives exist, with MP2104K27C3R6LC being the most promising pin-compatible candidate.
Lead pitch is a critical parameter for through-hole parts and varies among candidates.
Most candidates match or exceed key electrical ratings like voltage and capacitance.
Direct replacement for X2P2104KN1B0130120060ES0 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
MP2104K27C3R6LC is the strongest candidate, matching all key parameters including the 10mm pitch, but requires datasheet verification.
The primary risk is mechanical incompatibility. Several alternatives have a different lead pitch (e.g., 15mm) which will not fit a board designed for 10mm.

Strong parametric match with identical safety class, voltage, capacitance, and 10mm lead pitch. Requires review.
