Is there a pin-compatible replacement for CS11-E2GA222MYNSA?

The TDK CS45-E2GA222M-NKA shares the same 'Disc, Radial' package and pin count, making it a likely pin-compatible fit. However, its leads are straight, unlike the original's kinked leads, so physical clearance should be checked before assembly.

What risks should I check before replacing CS11-E2GA222MYNSA?

The main risk is using a capacitor without the correct X1/Y2 safety ratings, which is critical for line filtering applications. Also, verify the physical dimensions, including body size and lead spacing/form, to ensure it fits on your PCB.
