What This 50-Position CHAMP .085 Receptacle Does on the Harness

IDC Termination and Cable Assembly Fit

For the harness shop, this means a CHAMP.085 tool and a straight ribbon cable feed are the line requirements; no loose contacts or hand-loading. The free-hanging mount keeps the connector as a cable-end termination, not a board-mounted header, so the mating half is a CHAMP.085 plug or header with the same 50-position, 2-row layout.

Latch Lock Retention vs. Screw-Lock Alternatives

The integral latch lock on this receptacle replaces the 4-40 threaded inserts found on some CHAMP.085 housings. For a cable assembly that is frequently mated and unmated in the field, the latch speeds the connection — no screwdriver needed. The trade-off is that the latch provides less axial clamping force than a tightened jack-screw, so in high-vibration environments the screw-lock variant (with the 4-40 flange feature) may be preferred.

Frequently asked questions

What is the mating connector for 5553921-1?

The mating half is a CHAMP.085 series plug or header with the same 50-position, 2-row layout and outer shroud contact style. The latch lock on this receptacle engages with the corresponding latch on the plug.

What wire gauge does the IDC termination on 5553921-1 support?

The IDC termination is designed for standard 0.085-inch pitch ribbon cable. The specific wire gauge range is not listed in the available specifications — confirm the cable insulation diameter and conductor gauge against the TE application tooling recommendations before committing the harness build.
