Board-to-Board Mezzanine Fit
The 2307817-4: This 4-position, dual-row receptacle from the AMPMODU series mates with a matching 2.00 mm pitch pin header to form a board-to-board stack. The bottom or top entry design lets the receptacle sit on either the top or bottom side of the PCB, which helps when the mezzanine board needs to plug into a header on the main board from either direction. The surface-mount termination and pick-and-place feature mean this part is ready for automated assembly. The LCP housing holds up through reflow, and the UL94 V-0 rating keeps it inside equipment enclosures that require flame-rated materials.
The tin-plated solder tails are standard for SMT reflow. The phosphor bronze contacts handle the spring force without relaxing at the high end.
