ALJ
Needs validationmedium risk
78L12 matches the main electrical ratings but needs pinout and package confirmation.
Best Alternatives to CJ78L12
CJ78L12 is a 12 V, 100 mA SOT-89-3L linear regulator. The closest candidates need pinout and package review.

Can it be replaced directly?
Direct replacement for CJ78L12 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Start with 78L12, then verify pinout, exact SOT-89-3L fit, and temperature rating.
Main risk
Pinout is not verified; one close ST option also has a lower input-voltage rating.
