20 circuits at 2.50 mm pitch — board footprint fit
The 2-1827875-0: 20 positions loaded in two rows, with a 2.50 mm mating pitch and 3.30 mm row spacing — this sets the PCB footprint and the per-contact current ceiling at 5 A. The 0.098-inch pitch is standard for wire-to-board and board-to-board layouts in industrial control and general-purpose equipment. Shrouded on all four walls with a detent lock: the shroud protects the male pins during handling and guides the mating receptacle into alignment, while the detent gives a positive tactile click when fully seated — no risk of half-mated connections in a production harness. Board locks on the through-hole tails anchor the header to the PCB during wave soldering and resist shear forces from the cable assembly — a practical detail for panels where the harness gets routed and re-routed.
Gold mating finish — field-service duty
15.0 µinch gold over nickel on the mating face, with tin on the solder posts. Gold on the contact interface gives a stable, low-resistance connection over repeated mate/unmate cycles — rated for industrial environments where the connector sees periodic disconnect for maintenance or reconfiguration.
Active production — sourced per BOM
Active lifecycle status — the 2-1827875-0 is still in current manufacture from TE Connectivity. RoHS compliant.
