Can it be replaced directly?

Direct replacement for BZT52C10 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Prefer a same-package 10V BZT52C10 source; BZT52C12 is only a relaxed 12V option.

Main risk

Zener voltage changes will alter clamp or regulation behavior.
