The 4-175638-0 is a 10-position, 2-row board-to-board receptacle from TE's Fine Pitch series, with a 0.049" (1.25 mm) mating pitch that sets the board footprint and trace escape density. The SMD termination and board guide feature help align the receptacle during reflow, reducing tombstoning on dense PCBs.
The 4-175638-0 is a board-to-board receptacle; it mates with a matching pin header from the same Fine Pitch series with 0.049" (1.25 mm) pitch, 10 positions, 2 rows. The exact header part number depends on stack height and termination style — confirm the header's pitch and position count match before ordering.
Yes, 4-175638-0 is ROHS3 compliant, meeting the latest EU RoHS directive requirements for lead, mercury, cadmium, and other restricted substances.
The current rating is 0.5 A per contact. This is a signal-level interconnect — do not use for power distribution. The rating is derated at the upper end of the -30°C to 105°C temperature range.
The mating pitch is 0.049" (1.25 mm), with the same row spacing. This fine pitch enables dense board-to-board routing but requires careful PCB layout for trace escape and via fan-out.
