It uses a 0.031" (0.80mm) pitch in a dual-row arrangement, with center strip contacts that mate to the corresponding FH receptacle. This plug is surface-mount terminated and includes an integrated board guide feature that aligns the connector during pick-and-place, protecting the fine-pitch contacts from damage during assembly. The gold contact finish (8.00µin) on the mating interface provides consistent low resistance across repeated mating cycles, suited for production environments where boards are tested or reworked.
Mated Stack Height Range
The 5179029-8 supports mated stacking heights of 6mm, 10mm, 14mm, and 18mm when paired with the matching FH receptacle. The actual stack height depends on which receptacle height variant is selected; the plug itself has a fixed 0.220" (5.59mm) height above the board.
Compatibility and Mating
This plug mates with the TE Connectivity 5179028-8 receptacle (the same Free Height FH series, 160 positions, 0.80mm pitch). The two halves are keyed by the board guide feature — no separate polarization key is needed. For a given stack height, select the receptacle whose height above board, when added to the plug's 5.59mm, equals the target mated height from the 6/10/14/18mm range.
