What this connector is
The Amphenol 66925-516LF is the 32-circuit dual-row member of the Dubox series — a 0.100-inch (2.54 mm) pitch receptacle with a push-pull fastening type, female square sockets, and an insulation plug feature. It mounts right-angle through-hole on the PCB and is packaged in tube format.
Contact plating and what it means
Housing and flammability
The insulation body is glass-filled polyamide (nylon), rated UL94 V-0, in black. The insulation height is 0.240 inch (6.10 mm) and the post tail length is 0.115 inch (2.92 mm). Both rows are fully loaded with 32 positions.
Typical applications
Dubox push-pull receptacles at 2.54 mm pitch are used as board-to-board headers and wire-to-board connectors in industrial automation, instrumentation, and communications equipment where a reliable, compact dual-row interface is required. The push-pull latch provides a deliberate mate/unmate action without tool actuation.
Lifecycle and sourcing
Active — quoted to order against the BOM quantity. The base product number 66925 identifies the series entry; confirm the 32-position count and right-angle through-hole mounting orientation match the board layout.
