The post finish is 78.7 µinch tin, compatible with standard lead-free wave-solder processes. RoHS compliant. ## Housing and Environmental Ratings — UL94 V-0, Blue Thermoplastic Insulation color is blue, which aids visual identification on the board. The connector accepts bottom or top entry mating headers, with a push-pull fastening type — no locking latch, so it suits low-vibration stationary stacking rather than high-shock harness applications.","metaTitle":"71991-313LF Amphenol ICC (FCI) Dubox™ 26-Pin Female Socket","metaDescription":"71991-313LF Dubox™ 26-position dual-row receptacle, 0.100\" pitch, 30 µinch gold mating finish, through-hole solder, UL94 V-0.
