Product details

0.100" pitch, 2-position, friction-lock header

The 3-647050-2: The single-row layout and 1-wall shroud guide the mating housing straight on, and the friction lock holds it there without a secondary latch or screw. Rated 250VAC, with current capacity that follows the connected wire gauge — the tin-plated contacts carry the load within the UL94 V-0 nylon housing's temperature ceiling.

Mates with MTA-100 IDC receptacles

Mates with TE MTA-100 IDC receptacle housings (e.g., 640442 series) that accept 22-26 AWG discrete wire. The friction lock engages the matching ramp on the receptacle — no tools needed, audible click confirms the mate.

Frequently asked questions

What is the pitch of 3-647050-2?

0.100" (2.54mm) pitch — standard MTA-100 spacing, mates with any 0.100" pitch IDC receptacle.

Is 3-647050-2 RoHS compliant?

Yes, RoHS compliant per the current directive.

What is the current rating of 3-647050-2?

Current rating varies by wire gauge used in the mating receptacle — the header itself is rated for the full MTA-100 current range within the UL94 V-0 housing limit.
