2A, 200V board-to-board signal header
The 57102-S08-20LF: Gold GXT mating plating (15.0µin) and tin post plating (78.7µin) suit repeated mating cycles, while the UL94 V-0 thermoplastic insulation and push-pull fastening keep the footprint clean.
Dual rows on 0.079" (2.00mm) pitch with 0.079" row spacing give a 40-position through-hole footprint that fits a 2-layer board without tight trace neck-downs. The unshrouded push-pull header mates with a matching Minitek 2.00mm receptacle; the 0.157" mating length and 0.118" post length set the stack height.
