Verified drop-in options for RT9078-33GJ5 are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
Best Alternatives to RT9078-33GJ5
RT9078-33GJ5 is a 3.3V 300mA TSOT-23-5 LDO. The listed candidates need review because none is a proven pin-compatible 3.3V match.

Can it be replaced directly?
Direct replacement for RT9078-33GJ5 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Use the same 3.3V RT9078 option if available; otherwise review RT9080-30GJ5 only for 3.0V-tolerant rails.
Main risk
Output voltage mismatch and missing pinout evidence.
