The 171826-4 is a single-row, 4-position pin header from TE's EI series, designed to connect a cable assembly to a PCB at a right angle. Its 0.098" (2.50mm) pitch and 2A current rating suit signal or low-power circuits in general-purpose equipment.
Pitch, positions, and mounting orientation
With 4 positions on a 0.098" (2.50mm) pitch, this header fits compact board layouts where a small number of signal connections are needed.
Current, voltage, and contact finish
Rated at 2A per contact and 250VAC / 350VDC, this header handles signal-level loads and low-power circuits. The tin-plated mating finish suits applications with moderate mating cycles and indoor, non-corrosive environments. The brass contact material and 31.5µin (0.80µm) tin thickness on both the post and mating surfaces provide reliable solderability and contact performance for the rated life.
Housing material and regulatory compliance
Mating half and cross-reference note
As a male pin header, the 171826-4 mates with a female receptacle housing (not included). A functional alternative with a different pitch is the 1394090-1 (0.112" / 2.85mm pitch, 6 positions, 4-wall shroud) — verify PCB layout compatibility before substituting.
