Parts listed as alternatives are those which match these criteria precisely. Differences outside these parameters are not considered for alternate selection.

Parameter Comparison

Engineering Selection Recommendations

Selection between VI-J4J-EZ and VI-J4J-EZ-F1 is based on product status and compliance declarations. VI-J4J-EZ is classified as obsolete, making it unsuitable for new designs or for guaranteeing ongoing availability. VI-J4J-EZ-F1 provides an active status and maintains the same RoHS non-compliance and REACH unaffected status as the original. Only declared inventory and compliance information is considered in this selection.
