Product details

AMPMODU MTE 3-Position IDC Receptacle

IDC termination means the wire insulation is pierced by the contact tines during assembly — no stripping, no crimp tool for the contact itself. The 26-30 AWG range covers common signal-level wire gauges; 24 AWG is outside the stated range, so a 24 AWG build would need a different contact or termination method. The free-hanging (in-line) mounting lets this receptacle sit in a harness without a panel cutout or board mount.

The 3-position count matches a 3-position header — no partial population, no unused cavities. The black housing is keyed by the AMPMODU MTE polarization rib, so it cannot be reversed or mated with a different-series header. Stock both halves or neither: an orphan receptacle with no header on the shelf is dead stock.

Frequently asked questions

Where can I buy 103978-2 in single quantities?

103978-2 is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — no stock-holding claim is made here.

Is 103978-2 compatible with standard AMPMODU MTE headers?

Yes, the 0.100" (2.54mm) pitch and AMPMODU MTE series design mean this receptacle mates with standard AMPMODU MTE pin headers of the same 3-position count.

Can 103978-2 be used with 24 AWG wire?

No, the IDC termination is specified for 26-30 AWG discrete wire. 24 AWG is outside that range and would not terminate reliably in this contact.

Is 103978-2 RoHS compliant?

Yes, the part carries a ROHS3 compliance status.
