Current and Contact Durability
The 77313-124-10LF: The tin-plated solder posts (78.7 µinch / 2.00 µm) provide reliable solder wetting through wave or hand soldering.
Comparing the 10-Position BergStik Options
The 77313-127-10LF shares the same 10-position, 2-row, 0.100" pitch layout but has a shorter overall contact length of 0.465" (11.81mm) versus 0.480" (12.19mm) — the difference is in the mating pin length, not the board footprint. For higher position counts, the 77313-124-64LF offers 64 positions (2 rows × 32) with identical pitch, plating, and current rating — useful when scaling a design from 10 to 64 I/O without changing connector family.
