Gold Plating and Contact Construction
That plating grade supports 500+ mating cycles without contact resistance drift — relevant for test fixtures, programming jigs, or any application where the connector sees repeated connect/disconnect. In a high-shock environment, pair it with a receptacle that has a locking ramp.
These dimensions set the board-to-board stack height when mated with a standard 0.100" female socket — the total mated height is roughly the sum of the header's insulation height plus the receptacle's mating depth. All 18 positions are loaded — no skipped or dummy pins.
Lifecycle status is Active — no end-of-life notice or last-time-buy clock on this BOM line. The base product number is 68016; the -218HLF suffix encodes the specific plating, pin length, and packaging.
