Product details

2.00 mm IDC Receptacle for Discrete Wire Harnesses

Tin-plated female sockets handle the contact duty; the free-hanging, in-line mounting suits harness applications where the connector sits off the PCB, terminated directly to the wire bundle.

This works with 26-28 AWG discrete wire, and the natural-colour housing accepts the wire in a single pass. The trade-off: IDC connections are less forgiving of repeated rework than crimped terminals, so this connector is best specified for one-time harness assembly where the wire gauge and insulation diameter are controlled.

The free-hanging design means it does not require a board-mount footprint — it terminates to the wire and mates to a header that is either through-hole or SMT soldered to the PCB. The single-row 9-position layout keeps the mated pair narrow, which helps when the connector sits at the edge of a crowded board or inside a shallow enclosure.

Frequently asked questions

Does the 173977-9 have a mating plug or header?

Yes, the 173977-9 receptacle mates with a CT series male header (same 2.00 mm pitch, single row). The header is sold separately and is typically board-mount (through-hole or SMT).

What wire gauge works with the 173977-9?

The IDC termination accepts 26-28 AWG discrete wire. The insulation is pierced on insertion — no stripping or crimping needed at the wire end.
