The FCI (Amphenol) 57102-G08-17ULF is a dual-row, 34-circuit board-to-board header in the Minitek® 2.00mm series. Through-hole push-pull fastening anchors it perpendicular to the PCB; the 0.079 inch (2.00mm) row spacing matches standard Minitek receptacles so that the 34-position body slots into the same footprint as any other dual-row member of this series. Contact finish splits at the interface — gold GXT™ at 30.0 µin (0.76 µm) on the mating face, tin at 78.7 µin (2.00 µm) on the solder tails — which means the gold grade protects the wipe zone from fretting while the post gets the solderable tin bath. Rated 2 A per circuit at 200 V AC/DC; the insulation height of 0.059 inch (1.50 mm) sets the stand-off from the board surface and the overall contact length of 0.335 inch (8.51 mm) governs how deep the header sits in a mating receptacle.
What this connector does
Board-to-board perpendicular stack — the push-pull fastening (no screws or latches) locks the mating half in place during vibration. The square pin contact shape seats into a matching socket with two wiping surfaces; the gold GXT™ finish on the mating side gives lower contact resistance at first mate than tin while the tin post solders reliably. UL94 V-0 thermoplastic housing means it can go into enclosed equipment where flame retardancy is a compliance requirement.
Active production — sourcing posture
Listed Active. Quoted to order against the BOM quantity; no official successor order code for this specific part number. The 34-position count is the largest dual-row member of the 57102 base series.
