Samsung Electro-Mechanics
A same-vendor 0603 X5R functional option for layouts that can accept a larger MLCC.
CL05A225KO5NQNC is a 0402 2.2uF 16V X5R MLCC. The listed alternatives are larger-package redesign candidates, not verified drop-in replacements.
Voltage is stronger, but DC bias is unverified.
All candidates are larger than 0402.
Passive MLCC has no firmware interface.
All kept candidates are catalog matched.
Direct replacement for CL05A225KO5NQNC should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Prefer a 0402 2.2uF X5R ±10% part with at least 16V rating.
Package mismatch is the main risk.
