Board Fit and Routing Reality
The 68691-456HLF: With all 56 positions loaded, the board footprint spans 28 positions per row, so the overall length is roughly 2.8 inches (71 mm) along the mating axis. For a 56-position connector, this increases the risk of misalignment during blind mating; a shroud or guide pin would help in high-vibration or high-cycle applications.
Current and Thermal Budget
Rated 3 A per contact. In a typical signal application (0.5–1 A per pin), the margin is generous.
Packaged in a bag — not tape-and-reel, so pick-and-place assembly requires manual or tube feeding.
