The single-wall shroud leaves three sides of the pins exposed — this is a deliberate design for applications where the mating receptacle needs clearance on one side, or where the header sits near a board edge and the shroud would otherwise interfere with adjacent components. ## How the 2 A rating limits the circuit Compared to the 1394090-1 (6 positions, 2.85 mm pitch, 4-wall shroud, right-angle), the 171825-4 is a simpler, lower-density, straight-through option. The 0.112\" pitch of the 1394090-1 gives slightly more room for routing traces between pads, but the 171825-4's 2.50 mm pitch is still well within standard PCB fab limits. The natural (off-white) colour is standard for the EI series.","metaTitle":"171825-4 TE Connectivity Header, 4-Pos 2.5mm Pitch, Active","metaDescription":"171825-4 TE Connectivity AMP Connectors EI series header, 4 circuits, 2.50mm pitch, shrouded 1-wall, tin contacts, 2A, 250VAC, UL94 V-0.
