DB2EKM-3.81-3P-GN-S
DORABO
Needs validationmedium risk
Matches pitch, position, and voltage, but has a lower current rating. Requires engineering review.
Best Alternatives to XY303V-3.81-3P
Finding a substitute for the XY303V-3.81-3P terminal block involves careful consideration of electrical ratings. While several alternatives match the 3-position, 3.81mm pitch form factor, most have a lower current rating, requiring engineering validation for a safe replacement.
AI replacement insight
Electrical riskhigh
Most candidates have lower current or voltage ratings, requiring careful analysis of the application's power requirements.
Package risklow
Most candidates match the 3.81mm pitch and 3-position pluggable format, but check wire entry angle.
Can it be replaced directly?
No direct drop-in replacement was found. All candidates have electrical or mechanical differences that require engineering review.
Best replacement path
Use a candidate like WJ15EDGVM-3.81-03P-14-00A if a lower 8A current rating is acceptable for the application. Verify all electrical and mechanical parameters before substitution.
Main risk
The primary risk is electrical derating. Most alternatives have a lower current rating (8A vs 10A), and one has a significantly lower voltage rating (150V vs 300V).
