72 Positions at 0.100" Pitch — Board Fit First
The 68020-172HLF: The 0.230" (5.84mm) mating pin length gives enough engagement depth for standard box headers and shrouded receptacles.
3A per Contact — Signal-Level Current Ceiling
Rated 3A per contact, which is the per-pin current limit before the temperature rise exceeds the housing material's safe operating range. For a 72-position header carrying mixed power and signal, the total current budget is 216A if every pin is loaded — but in practice, derate for ambient temperature and adjacent pin heating.
