Is there a pin-compatible replacement for MPX104K31B3KN20600?

No, a pin-compatible replacement with the same 7.5mm lead pitch was not identified among the candidates. All functional alternatives require physical modification to fit the PCB due to different lead spacing.

What risks should I check before replacing MPX104K31B3KN20600?

The main risk is the package mismatch. You must verify that your PCB can accommodate a capacitor with a wider lead pitch (10mm or 15mm instead of 7.5mm). This may require bending leads or redesigning the board layout.

Finding a substitute for the KNSCHA MPX104K31B3KN20600, a 100nF X2 safety capacitor, requires careful attention to its 7.5mm lead pitch. While electrically similar parts are available, no direct pin-compatible replacements were found, making package verification essential.

AI replacement insight

Package riskhigh

All candidates have a different lead pitch (10mm or 15mm) vs the target's 7.5mm, preventing a drop-in fit.

Electrical risklow

Proposed alternatives match key electricals like capacitance, voltage, and safety class.

Can it be replaced directly?

No direct, pin-for-pin replacements were found. All viable alternatives have a different lead pitch (10mm or 15mm), requiring PCB layout verification or modification.
