Product details

2-Position IDC Receptacle, MTA-100 — Obsolete, Sourced to Order

It terminates 24 AWG discrete or ribbon cable with an insulation displacement contact — no wire stripping, no crimp tooling, just a one-step mass-termination press.

Obsolete — No Official Replacement Listed

No official successor order code or cross-reference is recorded for this specific 2-position variant. If the application allows a board respin, a current-production 0.100" pitch IDC receptacle from the same family or a different series would be the practical path, but no drop-in replacement is documented.

Mating and Termination — What Bolts In

This receptacle mates with any standard MTA-100 header — 0.100" pitch, 2-position, male pin header, either vertical or right-angle. No special tooling beyond a simple press or even a bench vise is needed for low-volume builds — the wire is positioned over the slot and pushed home.
