What this connector is
The 57102-F02-18ULF is the 32-circuit member of the Minitek® 2.00mm board-to-board header series. Dual-row, unshrouded, with square male pins in a push-pull fastening configuration — the header is designed to mate with the matching Minitek 2.00mm receptacle housing, creating a compact board-to-board or board-to-panel stack at 2.00 mm pitch.
Key ratings and what they mean for selection
The 32 positions and 2.00 mm dual-row pitch define the board footprint and routing density — match circuit count to the BOM line before committing. Rated 2 A per circuit at up to 200 V AC/DC, which places this firmly in the signal or low-power duty class; the current ceiling is set by the contact system, not the housing material. The mating-side contact finish is gold flash — the thin gold layer gives good wipe durability for the mating cycles the housing allows but is not a high-cycle premium plating. The post side carries 78.7 µin of tin for solderability and shelf life. Plating grade on the mating side is the primary signal-integrity marker here, not a power-handling indicator. Insulation is black thermoplastic rated UL94 V-0 — appropriate for industrial and commercial equipment where flame retardancy is required at the board level. The insulation height is 0.059 inch (1.50 mm) above the board surface. Post tail length is 0.098 inch (2.50 mm) below the board shoulder and the overall engagement length is 0.079 inch (2.00 mm) — the tail length governs the acceptable board thickness window in the stack-up; confirm your board thickness against this before selecting.
