02/01/2016	GCM 10708360 - Supplier Change. Molex will be changing the pre-plated flat stock, and adding an additional supplier. This change only affects parts made in Lincoln (3104) and Nogales (3105). The current pre-plated flat stock will change from bright tin over copper to reflowed tin over copper plating. In addition, we will also be changing the post plated terminal used in the 5566, 30069, & 43588 vertical headers to the same pre-plated reflowed tin over copper plating. If post plated headers are desired, alternative part numbers are available with matte tin over nickel plating.	Download
