Product details

Rated 1A per contact at 250VAC, the current limit comes from the narrow contact beam and the PCT housing's thermal rise — fine for signal-level I/O, not for power distribution.

Footprint and pinout — what to check before layout

Sourcing and compliance — active, RoHS, and how to buy

ROHS3 compliant, with a UL94 V-0 PCT housing.

How this compares to the 26-position sibling 1761681-9

The 26-position variant (1761681-9) shares the same 0.100" pitch, 2-row layout, gold mating finish, and shrouded housing. If your BOM calls for 26 I/O lines, the 1761681-9 is a direct swap on the same series; no need to re-qualify the mating half or housing material.

Frequently asked questions

Is 1761681-7 RoHS compliant?

Yes, it is ROHS3 compliant.

What is the pinout of 1761681-7?

All 20 positions are loaded in a 2x10 grid. The pinout is a straight row-to-row mapping — no skipped or empty positions.

What is the mating connector for 1761681-7?

It mates with a standard AMP-Latch IDC ribbon-cable receptacle that has a 0.100" pitch, 2-row layout, and a keying slot. The 4-wall shroud guides the receptacle into alignment.
