Product details

Shrouded 2-Pin Header for Wire-to-Board Duty

Rated 250 VAC, with current dependent on wire gauge per the MTA-100 derating curve.

This part is officially listed as Obsolete by TE Connectivity. No direct successor is documented. Buyers with existing BOM lines should plan for a redesign or source through independent channels. We source 644486-2 through our multi-supplier network; availability and pricing are confirmed at RFQ.

This header mates with MTA-100 series IDC receptacles and crimp-style housings that share the 0.100" pitch and friction lock slot. The through-hole solder tails (0.140" post length) suit standard PCB thicknesses around 1.6 mm.

Frequently asked questions

Is 644486-2 still available for purchase?

644486-2 is obsolete, but we can source it through independent distribution. Submit an RFQ for current availability and pricing — no stock guarantee is made without a confirmed quote.

What is the replacement for 644486-2?

TE Connectivity has not published a direct replacement for this specific 2-position MTA-100 header. Check the MTA-100 series for similar shrouded headers with the same pitch and lock style; a board spin may be needed if the pin count or footprint differs.

Is 644486-2 compatible with MTA-100 connectors?

Yes, this header is part of the MTA-100 series and mates with MTA-100 receptacles that use the 0.100" pitch and friction lock feature. Confirm the mating half's position count and locking mechanism before ordering.
