Termination and board fit
The 090122-0773 is the 26-circuit member of Molex's C-Grid III 90122 breakaway header line, unshrouded with a push-pull fastening type. It terminates through-hole right-angle with 0.114" (2.90 mm) post length, mates at 0.266" (6.75 mm) contact length, and carries gold-plated mating contacts on a 0.100" (2.54 mm) pitch.
Series and position count
Within the C-Grid III 90122 series the 090122-0773's 26 positions sit between the 24- and 30-position siblings — the 0.100" (2.54 mm) pitch, dual-row layout, and gold mating finish are shared across the series, so match the position count to the circuit count.
