Product details

2-Pin 0.100" Pitch MTA-100 Header

The 3-647609-2: The friction lock provides retention against vibration-induced separation, a practical feature for harness applications where the connector pair sees movement or shock.

This header mates with the MTA-100 series receptacle housings and IDC connectors. The single-row 2-position layout accepts the corresponding female connector with a friction-lock ramp — the lock engages when the plug is fully seated, giving an audible click that confirms the mate. The 0.290" mating contact length ensures full engagement depth with the receptacle terminal. For wire-to-board builds, pair this header with the matching MTA-100 crimp socket housing and 20-24 AWG terminals — the current rating depends on the wire gauge selected.

Frequently asked questions

Is the TE 3-647609-2 RoHS compliant?

RoHS compliance is standard for TE's MTA-100 series. The tin plating on contacts and the PBT housing material are consistent with RoHS requirements. Verify compliance documentation with your TE representative or distributor at order time.

What is the difference between 3-647609-2 and 3-647609-1?

Both are MTA-100 2-position headers with the same pitch, locking, and plating. The difference is in the contact finish or packaging variant — check the specific datasheet for the exact delta. Both are active and share the same mating half.
