6-Position IDC Receptacle for Discrete Wire Harnesses
Position Counts Across the CT Series
The 173977-6 sits at 6 positions in the CT IDC receptacle family. The 5-position 173977-5 and 7-position 173977-7 are the immediate neighbours — same pitch, same tin finish, same free-hanging mount.
Active Lifecycle and Sourcing
No obsolescence notice or last-time-buy date is on record.
Termination is IDC: strip the wire, insert it into the slot, and press down — the insulation is displaced by the contact tines, making gas-tight connection without crimping. The free-hanging (in-line) mount means the connector floats in the harness, not fixed to a panel or board, so strain relief depends on the wire bundle routing.
