The 77313-402-48LF: All 48 positions are loaded, so no depopulation to account for. This saves board space and keeps the profile low, but in high-vibration environments the connection relies entirely on the receptacle's latch, not a header shroud.
The square pin geometry (0.025" square typical for BERGSTIK®) provides a reliable gas-tight interface with the receptacle's contact spring.
All positions are loaded.
The spec table on this page carries the confirmed ratings. A full product drawing is available through Amphenool ICC (FCI) under the base number 77313.
The key variable is the contact plating — tin vs gold — which affects mating cycle life and corrosion resistance.
