For higher cycle duty, the sibling 71991-302LF and 71991-305LF carry 30.0 µinch gold, doubling the wear layer. The 4-position 71991-802LF is the smallest circuit count in the 71991 series. RoHS compliant and rated UL94 V-0 for the glass-filled thermoplastic housing.","metaTitle":"71991-802LF Amphenol ICC Dubox™ 4-Position Female Socket","metaDescription":"71991-802LF 4-position, 0.100\" pitch, through-hole receptacle.
