Product details

Right-angle through-hole mount for board-edge harness routing

The one-wall shroud and friction lock keep the mating housing aligned and engaged under moderate vibration, without needing a secondary latch. 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.

Frequently asked questions

What connector mates with 1718571005?

This is a KK254-series male header. It mates with the corresponding KK254 crimp receptacle housing (e.g., Molex 5045 series or 6471 series) using the appropriate crimp terminals. The friction lock engages with the mating housing's lock ramp.

Is 1718571005 RoHS compliant?

Yes, it is ROHS3 compliant. No replacement needed for RoHS reasons.
