Pitch and Position Count — First Footprint Decision
Unshrouded, push-pull fastening — no polarization key or locking ramp, so the mating half must align by the board layout alone. Fine for a fixed cable harness inside an enclosure; skip it where vibration can work the connection loose.
Current, Plating, and Contact Life
At 3 A the housing stays within its UL94 V-0 thermoplastic limit. In a field-service application cycled quarterly, the contact interface outlasts the product life.
Comparing Position Counts — 16 vs 20 vs 14
The 16-position 77313-824-16LF shares the same 0.100" pitch, row spacing, gold plating, and 3 A rating with the 20-position 77313-824-20LF and the 14-position 77313-818-14LF. All three are active and unshrouded; the board footprint scales linearly with position count. No other parametric delta worth a cross-reference.
