Board Layout Fit: Pitch, Orientation, and Footprint
The 77317-404-22LF: The unshrouded breakaway design means the 22-position strip can be snapped to shorter lengths if needed, but there is no shroud to guide the mating half — alignment depends on the receptacle's polarization features.
Current Rating and Contact Plating: What the Numbers Mean
Rated 3 A per contact with tin-plated mating surfaces — the tin finish is adequate for occasional mating (50 cycles typical) in clean, dry environments, but in high-humidity or corrosive settings the contact resistance may drift over time compared to gold.
Lifecycle and Sourcing Status
The BERGSTIK series includes many pitch and row-count variants; a pin-compatible alternative would need the same 0.100" pitch, 22 positions, 2 rows, and right-angle orientation.
