Yageo
Electrically strong match but in a smaller 0805 package, requiring a different board layout.
Yageo's CC1206KRX7R9BB223 is a standard 22nF, 50V MLCC in a 1206 package. While no direct drop-in replacements were found, several functional and parametric alternatives are available that require either a PCB redesign or careful validation of different electrical values.
Many functional alternatives are in different packages (0402, 0805, 1812) and are not drop-in compatible.
Candidates in the same package have significantly different capacitance values, which can affect timing or filtering.
No, there are no direct, pin-for-pin replacements with identical key parameters among the candidates reviewed. Substitutes either have a different package size or a different capacitance value.
If a PCB redesign is feasible, parts like GCM155R71H223KA55D offer identical electrical function. If the 1206 package is required, circuit tolerance for different capacitance values must be verified.
The primary risks are package mismatch, which requires a PCB redesign, and capacitance mismatch, which can alter the circuit's electrical behavior and requires engineering validation.

The best alternative depends on your design constraints. If you can change the PCB layout, Murata's GCM155R71H223KA55D is an electrically identical option in a smaller 0402 package. If you must use the 1206 package, no exact match was found, and you must verify if your circuit can tolerate a different capacitance value.
