80-Position Board-to-Board Plug with Board Lock
The TE Connectivity CHAMP.050 I 1734099-8 is an 80-position board-to-board plug with center strip contacts arranged in two rows. This right-angle through-hole connector uses solder termination and includes an integrated board lock feature for mechanical retention during reflow and against vibration in the mated assembly. The gold flash contact finish provides corrosion protection for the mating interface, though the thin plating limits the connector to a modest number of mating cycles — suitable for one-time or infrequent disconnect applications rather than repeated field-service duty.
Position Count and Series Positioning
At 80 positions, the 1734099-8 is the highest-density member of the 1734099 series within the CHAMP.050 I family. The series also includes 68-position (1734099-7), 50-position (1734099-5), and 40-position (1734099-4) variants, all sharing the same right-angle through-hole footprint, board lock, and gold flash contacts. The position count is the only meaningful selection difference — the board layout and mating receptacle must match the circuit count exactly.
