AI replacement insight

Package riskhigh

Wire entry angle (vertical vs. right-angle) is a critical form-factor difference that can make a part unusable.

Electrical riskmedium

Selecting a part with a lower current rating (e.g., 7A vs 8A) can lead to overheating and failure.

Can it be replaced directly?

Yes, `DB127S-3.81-2P-GN-S` is a pin-compatible upgrade. `XY303V-3.81-2P` is a very close cross-vendor alternative. Always verify mechanical dimensions from the datasheet before production.

Best replacement path

The best replacement is `DB127S-3.81-2P-GN-S` from the same manufacturer, offering a pin-compatible footprint and an upgraded 10A current rating. For a cross-vendor option, `XY303V-3.81-2P` is a strong match.

Main risk

The main risks are selecting a part with a different wire entry angle (right-angle vs. vertical) or a lower current rating.

Recommended alternatives

Pin-compatible upgrade from the same manufacturer with a higher 10A current rating.
