Product details

Two-Position Header with 3.96mm Pitch for Wire-to-Board

The 2-647123-2 is a single-row, 2-position header from TE's MTA-156 series, designed for Board to Cable/Wire interconnects. This lock resists vibration-induced disconnection in industrial and general-purpose equipment. The insulation material is glass-filled thermoplastic rated UL94 V-0.

Through-Hole Mounting and Solder Termination

The header mounts through hole, with solder termination to the PCB. Insulation height of 0.525" (13.34mm) provides clearance above the board for wire routing.

Voltage and Temperature Ratings for Industrial Duty

Rated 600VAC, the header suits line-voltage control circuits and power distribution within industrial cabinets. The current rating varies by the wire gauge of the mating terminal — in the MTA-156 system, the terminal and wire size set the actual ampacity, not the header alone.

Frequently asked questions

What is the exact pitch of 2-647123-2?

The pitch is 0.156" (3.96mm), measured center-to-center between adjacent pin positions.

Is 2-647123-2 RoHS compliant?

Yes, it is listed as RoHS compliant.

What is the mating connector for 2-647123-2?

The header mates with MTA-156 series receptacle housings that accept the corresponding crimp terminals — the housing and terminal are separate line items in the same series.
