70-Position CHAMP Receptacle for Dense I/O
The TE Connectivity CHAMP 2129390-2 is a 70-position receptacle with outer shroud contacts, built for high-density parallel I/O connections in telecom, networking, and industrial equipment where signal count per board edge matters. The 2-row layout packs 70 circuits into a right-angle solder mount that can be placed either as a surface-mount or through-hole part — a rare dual-footprint option that lets a single BOM line serve different assembly lines.
Board Layout Fit: 70 Positions, Dual Mount
The 70 positions at a 2-row pitch typical of CHAMP series means the board footprint occupies roughly the same edge real estate as a 50-position D-sub but with more signal density.
This is not a power-grade plating; the gold layer preserves contact resistance stability over repeated mates, not bulk current capacity.
