Is there a pin-compatible replacement for DB127V-5.0-4P-GN-S?

WJ128V-5.0-04P-14-00A shares the same 5.0mm pitch, 4-pin vertical footprint, but is not electrically identical due to a lower current rating. A fully pin-to-pin compatible part has not been identified.

What risks should I check before replacing DB127V-5.0-4P-GN-S?

Key risks include mechanical and electrical mismatches. Verify the substitute's pitch (must be 5.0mm), orientation (vertical vs. right-angle), and ensure its voltage and current ratings (300V, 15A) are met or exceeded.
