140-Position Mezzanine Receptacle at 0.50mm Pitch
Board guide features aid alignment during SMT placement, and solder retention features hold the part steady through reflow.
The mated stacking height of 2mm is the dimension that decides whether this connector fits your z-height budget between parallel boards. At 0.065" (1.65mm) above the mounting board, the receptacle sits low — the mating header contributes the remaining height to reach the full 2mm stack. The 0.50mm pitch means trace routing between pads is tight; expect to use micro-vias or fine-line PCB fabrication for breakout. The dual-row layout with center strip contacts gives a balanced footprint for the 140 positions.
