2.00 mm Pitch, 10 Circuits — Board-to-Board Breakaway Header
The 1-2842138-0: The tin-plated posts (78.7 µinch) solder reliably into plated through-holes. The 0.157-inch mating pin length and 0.110-inch post length give a total contact length of 0.327 inches — enough for a standard PCB thickness of 1.6 mm with a through-hole solder joint.
Lifecycle status is Active — the part is still in TE's current catalog with no end-of-life notice. ROHS3 compliant.
Unshrouded Layout — Board-Space Trade-Off
Unshrouded headers save board real estate but provide no polarisation key — the mating receptacle must be keyed or the harness orientation fixed by the PCB layout.
