It uses outer shroud contacts in a dual-row arrangement at a 0.016\" (0.40mm) pitch — tight enough to pack 70 signal lines into a compact footprint, but the shroud gives the contacts some mechanical protection during handling and mating. The 1.14mm height above board, combined with mated stacking heights from 1.5mm to 4mm, means this single header can serve multiple board gap budgets in the same design by swapping the receptacle half. ## Pitch, Positions, and Stack Height — What Drives the Fit The 0.40mm pitch is the defining constraint for the board layout engineer. It forces fine trace routing and a tight keep-out zone — not a connector you hand-solder. The 70 positions match a 70-circuit BOM line; the dual-row layout means 35 contacts per row, so the footprint is a narrow 0.40mm-pitch staggered grid. The mated stack height depends entirely on the receptacle chosen — the BergStak 0.40mm system supports 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, or 4mm stack heights, so you pick the receptacle that gives the board-to-board gap your enclosure needs. Gold flash on the contacts — that's the thinnest gold grade, specified as Flash in the plating thickness. If your application needs hundreds of mating cycles, you'd want a thicker gold layer, which this series doesn't list. The gold does keep the contact interface corrosion-free in indoor environments. The BergStak 0.40mm series offers the same 1.14mm height and 0.40mm pitch in 40, 70, 80, and 100-position variants. The 10164228-0701A1RLF sits at 70 positions. If the BOM calls for 80 circuits, the 10164228-0801A1RLF shares the same pitch, height, and dual-row shroud design — just more positions. The 40-position (10164228-0401A1RLF) and 100-position (10164228-1001A1RLF) are the other endpoints. All are active and RoHS3 compliant, so the choice is purely about circuit count matching the board design. The 10164228-0701A1RLF is a current-production BOM line. RoHS3 compliant, so it passes the environmental requirements for European and most global markets.","metaTitle":"Amphenol BergStak 0.40mm 10164228-0701A1RLF","metaDescription":"Amphenol BergStak 0.40mm 10164228-0701A1RLF, 70-position dual-row header with outer shroud contacts. 0.016\" (0.40mm) pitch, 1.14mm board height.
