Gold on the mating contact surface (15.0µin) supports repeated connect/disconnect cycles; tin on the solder tail keeps the through-hole joint reliable. ## Pitch and footprint — standard KK254 grid At 0.100\" pitch, this header matches the classic KK254 footprint — the same grid used across Molex's KK series for wire-to-board and board-to-board interconnects. The 5 positions are all loaded. The mating pin length is 0.265\" (6.73mm), and the post length is 0.100\" (2.54mm) — typical for a standard through-hole solder joint on a 1.6mm board.","metaTitle":"Molex 1718571005 KK254 Header, 5 Pos, 2.54mm, Right Angle","metaDescription":"Molex 1718571005 KK254 5-position single-row header, 0.100\" pitch, right-angle through-hole, gold mating contacts, friction lock.
