Is there a pin-compatible replacement for ERE1CM331F11OT?

Yes, SPZ1EM331F11O00R is a pin-compatible replacement. It has the same 8x11mm radial can package and 2-pin layout, allowing it to be a drop-in replacement on the PCB.

What risks should I check before replacing ERE1CM331F11OT?

Before replacing ERE1CM331F11OT, you must verify the substitute's package type and dimensions. The target is a radial 8x11mm part; using an SMD part or a larger radial part requires board changes or fit verification. Also, check if secondary parameters like ESR and ripple current are suitable for your application.
