Dubox 10-Pin Header — Board-to-Cable Fit
The 91687-305LF: The friction lock holds the mating half in place under moderate vibration — enough for a stationary panel or cabinet interconnect, but not a high-shock automotive environment. The GXT plating is a hard gold alloy that extends mating cycle life beyond standard gold — expect several hundred cycles before the contact resistance drifts. For a field-service connector cycled a few times a year, that is decades of reliable service.
The post finish is tin (78.7 µin), which wets well with lead-free SAC solder profiles. Insulation height is 0.368" above the board — account for this z-height when routing cables over the header. The blue polyester housing carries a UL94 V-0 flame rating, so it is acceptable inside equipment enclosures that require flammability certification.
Supplied by Amphenol ICC (FCI) under the base number 91687. No official pin-compatible alternative or successor is listed in this series — the Dubox line is stable and the 10-position, 0.100" pitch, friction-lock variant is a standard catalogue item.
