At 0.156" pitch, the 3-position version is a compact drop for low-circuit-count harnesses. The 30.0µin gold distinguishes this variant from tin-plated siblings — it is the right choice when the mating cycle count or environmental exposure exceeds what a tin contact can handle.

Frequently asked questions
Does 3-644718-3 work with standard MTA-156 headers?
Yes. The 0.156" (3.96mm) pitch and single-row layout are standard MTA-156 dimensions, so this receptacle mates with any MTA-156 pin header of the same position count and pitch. The polarizing key ensures correct orientation.
What is the replacement for 3-644718-3?
The part is still active, so the current order code is the correct BOM line item.
