Board Layout Fit for a 200-Position Mezzanine Plug
The 0.031" (0.80mm) pitch and dual-row layout demand a tight board footprint — each signal pair routes between the pads, and the 200 circuits fill a board edge about 80mm long. The plug mates with a Free Height receptacle at one of four stacking heights: 5mm, 9mm, 13mm, or 17mm, giving the board stack-up designer a range of z-axis spacing options from a single connector pair.
The 1-5177984-0 plug itself sits 0.181" (4.60mm) above the board. The mated stack height — the distance between the two PCBs — is set by the receptacle half, not the plug. Four standard receptacle heights give 5mm, 9mm, 13mm, or 17mm total stack. That means one plug BOM line covers all four spacing options; the procurement decision is which receptacle height the enclosure needs.
RoHS3 compliant per the listing, which covers the European Union directive for the current production run.
