Is there a pin-compatible replacement for 0402B104K250NT?

Yes, 0402B104J250NT is a pin-compatible replacement. It shares the same 0402 package and electrical function. Another part, 0402B104K100NT, is also pin-compatible but has a lower voltage rating and is not a safe drop-in replacement.

What risks should I check before replacing 0402B104K250NT?

The primary risk is using a substitute with a lower voltage rating. The target is rated for 25V; a replacement rated for 10V, for example, could fail under normal operating conditions. Always verify the voltage, capacitance, and tolerance before making a substitution.
