Board-to-board or cable header, 50 positions
The 4-103186-0-25 is the 50-position member of TE's AMPMODU Mod II breakaway header line, unshrouded, dual-row, 0.100" pitch. Rated 3 A per contact, gold-plated mating contacts (15.0µin), through-hole solder termination, UL94 V-0 thermoplastic housing, operating range -65°C to 105°C.
Pitch, footprint, and plating across the series
The 0.100" pitch and 0.100" row spacing are shared across the AMPMODU Mod II series, so the board footprint is consistent regardless of position count. Gold mating contacts (15.0µin) suit repeated mating cycles; the tin-lead post finish (100.0µin) matches standard solder processes.
