120-Position Mezzanine Receptacle at 0.80 mm Pitch
The 0.031" (0.80 mm) pitch and dual-row layout pack 120 circuits into a compact footprint, making this a high-density interconnect for space-constrained PCB assemblies. Outer shroud contacts protect the signal pins during mating and provide initial guide-in before the contacts engage. The key selection parameter here is the mated stack height range: this single receptacle supports four stacking heights — 13 mm, 14 mm, 15 mm, and 16 mm — depending on which mating plug height you pair it with. That flexibility lets you use one board layout across multiple enclosure depths without respinning the PCB.
Stack Height Selection and Board Spacing
The 5084616-5 receptacle mates with the corresponding Free Height (FH) plug to achieve a mated stack height of 13 mm, 14 mm, 15 mm, or 16 mm. The actual height is determined by the plug variant selected — the receptacle itself has a fixed height above board of 0.463" (11.75 mm). When specifying the pair, confirm both the receptacle and plug part numbers to hit the target board-to-board spacing. At 0.80 mm pitch, the routing density between the two boards is high. The outer shroud contacts provide some electrical shielding between signal rows, but for differential pairs or high-speed signals, check the signal integrity guidelines in the FH series application note.
Comparison with Peer: 1-120532-2
The 1-120532-2 is a different connector family — a 1.00 mm pitch, 84-position plug with center strip contacts, not a direct alternative to the 5084616-5. The pitch difference alone (0.80 mm vs 1.00 mm) means the board footprints are incompatible. If you are sourcing a replacement for the 5084616-5, the correct path is to stay within the Free Height (FH) series at 0.80 mm pitch; the 1-120532-2 is not a functional substitute.
