The single-wall shroud protects the pins from one side, reducing mis-mate risk without adding bulk. The UL94 V-2 nylon housing meets the flame rating needed for enclosed gear. No single-vendor lock; the KK254 series is widely second-sourced, so cross-references to other 0.100\" pitch headers are possible with a footprint check. ## Board layout and mating checklist The post length is 0.100\" (2.54mm) — typical for a 1.6mm-thick PCB; verify the board thickness and solder fillet clearance. The friction lock requires the mating receptacle to have the corresponding lock ramp. Standard KK254 crimp housings (e.g., 50-57-9403 for 3 circuits) include this feature.","metaTitle":"Molex 1718573003 Header, 3 Pos, 2.54mm, Right Angle","metaDescription":"Molex 1718573003 KK254 header, 3 circuits, 0.100\" pitch, through-hole right angle, tin plating, friction lock.
