60-Position Mezzanine Fit: Pitch, Stack Height, and Contact Grade
The 76342-330SLF: The mated stacking height is 11.04mm — that number sets the board-to-board gap in a mezzanine or parallel-stack design. The contact length below the insulator is 0.114" (2.90mm), which sets the through-hole drill depth and solder fillet height.
The insulator height is 0.275" (6.99mm) above the board surface. Combined with the 0.114" post length, the total through-hole depth is about 0.389" (9.89mm) from the top of the housing to the solder tip — check this against your board thickness and keep-out zone on the opposite side.
The base product number is 76342, which covers the 2-row, 2.54mm-pitch Dubox receptacle family. The suffix -330SLF encodes the 60-position, gold plating, and tube packaging. No direct pin-compatible replacement or cross-reference is listed from the manufacturer.
