Dual-row breakaway header, 78 positions
The 090122-0799 is the 78-position member of Molex's C-Grid III 90122 breakaway header line, configured as a dual-row unshrouded header for board-to-board or cable applications. Mating contacts are gold-plated (15.0 µin) over brass square pins, with tin-plated solder tails for the through-hole right-angle mount. The housing is rated UL94 V-0.
Gold mating contacts and 2.54 mm pitch
The 0.100" (2.54 mm) pitch and 0.100" row spacing define the board footprint — the same grid is shared across the C-Grid III 90122 series, so position count is the primary selection variable. Gold on the mating side supports repeated mating cycles; the 15.0 µin thickness is suited for moderate reconnect duty in automotive or general-purpose environments.
