Board-to-Board Stacking Fit
The 65781-006LF: The through-hole solder tails extend 0.140" (3.56mm) below the insulator — enough for a standard 1.6mm PCB with wave-solder fillet.
The post finish is gold flash, which is purely for solderability and shelf-life protection.
Housing and Flammability
The insulator is black glass-filled polyester rated UL94 V-0 — the highest vertical burn rating for a connector housing. The glass fill also improves dimensional stability during wave solder, reducing warp on the 8.51mm (0.335") tall body.
