6 loaded of 7 positions
The 5-104878-8 is a 7-position header from TE's AMPMODU Mod II breakaway line, with 6 positions loaded — the unloaded position allows the user to snap off the extra pin for a custom circuit count. Black thermoplastic insulator, 0.090" (2.29 mm) insulation height.
Position count vs loaded count
The 5-104878-8 carries 7 pin positions in the insulator but only 6 are loaded with contacts — the seventh position is a breakaway snap-off tab. This gives the harness builder a single part that covers both 6- and 7-circuit BOMs by snapping the tab when 6 circuits are needed.
