Board-to-wire header with a 6.35mm pitch and locking ramp
The 0.250" (6.35mm) pitch gives you room to route heavier wire gauges without crowding the board. The shrouded 4-wall housing and locking ramp fastening type provide a secure mate under vibration — the ramp holds the plug in place without relying on a separate latch.
What the gold mating finish means for your application
The post finish is tin, so the solder joint is standard tin-lead compatible. The 3-position count is fully loaded — all positions are populated, no empty cavities to manage.
The 1318699-3 is a 4-row, 12-position header with a 0.165" (4.20mm) pitch, rated 5 A and 250 VAC, with a latch lock and UL94 V-0 housing. The 350583-4 is a single-row, 3-position part with a wider 0.250" pitch and a locking ramp — different density and retention mechanism.
