Can it be replaced directly?
Direct replacement for CL31A476MQHNNNE should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Start with Samsung CL31A476MPHNNNE, then TDK C3216X5R1E476MTJ00E if higher voltage and height are acceptable.
Main risk
MLCC DC bias and case height may differ even with the same 1206 size.
