Right-angle SMD fit for tight boards
Gold flash on the mating contact handles moderate mating cycles.
Peer comparison: pitch and locking style
The closest functional second-source in the evidence is 1-2232960-3: also 3 positions, single row, board-to-cable, but with a 2.50 mm pitch (wider), through-hole mounting, a 4-wall shroud, and a locking ramp instead of a friction lock. The 1909782-2's 1.20 mm pitch saves 52% board width per row, but the through-hole peer offers a stronger mechanical anchor for high-vibration harnesses.
