What this connector is
The Molex 66925-517 is the 34-circuit member of the Dubox™ series — a dual-row 0.100" (2.54mm) pitch receptacle with an integral insulation plug housing. Gold-plated on the mating face (30.0µin (0.76µm)) and tin-plated on the solder tail (100.0µin (2.54µm)), it mates with standard 0.100" pitch headers in the Dubox family. The push-pull fastening type provides positive retention without jack-screws — the housing latch snaps into the header slot and releases by pulling the housing body.
