Can it be replaced directly?
Direct replacement for 0402ESDA-05N should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Start with BPESD0402-05ST or PESD0402V05, then verify pinout, leakage, clamp, trigger voltage and temperature.
Main risk
ESD parts with the same 0402 package can still clamp or leak differently.
