Can it be replaced directly?

Direct replacement for CG0603MLC-05E should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Start with CG0603MLC-05LE, then verify pinout, AEC-Q200, capacitance and ESD ratings.

Main risk

Capacitance, standoff voltage and qualification differences can change high-speed line protection.
