It uses the industry-standard 0.100" (2.54mm) pitch on both rows and between rows, matching the footprint of a standard 40-pin DIP layout. Rated 5A per contact at 110V, with a 30.0µin (0.76µm) gold mating finish — the plating grade supports repeated mating cycles in environments where tin would wear through.
Any standard 0.100" pitch IDC socket or BergStrip receptacle with 40 positions will fit, provided the row spacing also matches at 0.100" (2.54mm).
The overall contact length of 0.990" (25.15mm) breaks down into a 0.770" (19.56mm) mating section and a 0.120" (3.05mm) solder post. When mated with a standard 0.100" pitch receptacle, the total stack height is the sum of the receptacle's insulation height plus the 0.770" pin exposure — a common configuration for parallel-board spacing in the 0.800" to 1.000" range. The through-hole solder posts require drilled plated-through holes on a 0.100" grid; the 0.120" post length is compatible with standard 0.062" to 0.093" board thicknesses.
The 87052-140HLF is an active, current-production part.
