Is there a pin-compatible replacement for Y5V103M2KV16CC0204?

Not verified. The closest candidate has matching 2-pin disc format, but PDF and body-size checks are still needed.

What risks should I check before replacing Y5V103M2KV16CC0204?

Check voltage margin, temperature range, body diameter, lead form, and whether the capacitor is used in a safety-critical HV path.

Y5V103M2KV16CC0204 is a 10nF 2kV Y5V ceramic disc capacitor. The closest listed alternative needs review, not drop-in approval.

Same 10nF and 2kV, but no 1.1x voltage margin.

Lead spacing matches; body size is missing.

Passive capacitor; no firmware impact.

Lifecycle for best candidate is not explicit.

No verified pin-compatible replacement is proven from the indexed fields.

Review CT81-M12Y5V1D103MSE first for same value, voltage, dielectric, and 7.5mm disc format.

Equal 2kV rating leaves no extra voltage margin, and body size/temperature are not fully checked.

Closest listed option: same 10nF, 2kV Y5V disc format; verify temperature and body size.
