16 positions, 2.00 mm pitch – board-fit anchor
The 2842142-8: The 0.079" (2.00 mm) row spacing matches the mating pitch, so the board layout is a simple 2×8 grid with no staggered routing.
Gold mating finish – 3.94 µinch, reliable reconnect
The mating contacts are gold over copper alloy, with a thickness of 3.94 µinch (0.100 µm). Gold prevents oxidation and maintains stable contact resistance through repeated mating cycles; for a connector that may be disconnected a few times over its life, this finish is more than adequate.
Unshrouded breakaway – flexible but no keying
An unshrouded header with push-pull fastening means the connector relies entirely on the mating receptacle's retention for vibration resistance. There is no locking latch or polarization key, so the board layout must ensure the mating half is aligned correctly.
SMD termination, pick-and-place compatible
Surface-mount termination with pick-and-place features means this header is suited for automated assembly.
Peer comparison – 16 vs 12 vs 10 positions
The 2842142-8 (16 positions) is the highest-density option in this breakaway subfamily. The 2842142-6 carries 12 positions and the 2842142-5 carries 10 positions, all with identical pitch, plating, and SMD termination.
