4-position dual-row in a 4.20 mm pitch series
The 4-1775099-0: This is the 4-position member of the TE ATX series — a dual-row shrouded header on 0.165" (4.20 mm) pitch, with both rows loaded. At 4 circuits it is the smallest position count in the ATX dual-row lineup; the sibling 4-1775099-7 carries 20 positions on the same pitch and contact finish. Rated 9 A per circuit at 250 VAC, the current limit is set by the tin-plated brass contacts and the PA9T housing's UL94 V-0 rating.
Locking ramp and through-hole mounting
Fastening is a locking ramp — the header clicks into the mating receptacle and holds under vibration without separate hardware. Insulation height is 0.504" (12.80 mm), giving clearance for the receptacle body above the board.
