Board Fit and Footprint Reality
The 77311-804-36: The insulation height is also 0.100" (2.54 mm), so the plastic body sits low on the board — useful when the mating half has a tight z-height budget. The post finish is tin-lead at 150 microinches, which solders well with standard wave or hand-solder profiles.
That means any BOM line using this part number is at risk: the original production has stopped, and the only channel is independent surplus or distributor inventory. We source this part through our multi-supplier network — availability is lot-specific and confirmed at RFQ. No stock-holding claim; each order is quoted against the BOM quantity.
Mating and Compatibility Check
The square 0.025" square pins are the BergStik standard — they fit into crimp sockets, machined sockets, or IDC receptacles with the same pitch. No IP rating is listed, so this is an indoor, dry-environment connector.
