The 1-794455-1 is the 20-circuit member of TE's AMP-DUAC header line, a dual-row shrouded board-to-board or cable connector. Tin-plated mating contacts carry 600VAC across 0.165" (4.20mm) pitch rows, with a locking ramp for vibration resistance and a board lock for through-hole retention.
A board spin is required for any functional replacement.
