That's the problem with saying that you're looking for a "molex connector". Molex is a brand and they only have a bazillion different styles of connectors. What spacing do you need? Do you want it keyed? Latch? Friction fit? pins or blade connectors... If you really want that style of connector molex brand, then [http://www.digikey.com/product-detail/en/0050579004/WM2802-ND/115008]here's your connector[/url]. But you end up paying about twice what you can get the same part from a "lesser" brand.Quote

I don't think that it is a Molex-brand connector, but rather a 0.1" spacing pin header plug.
The style of connector that should be used is determined by what he's plugging it in to. A latched or key plug is pointless if the header pins are just standard header pins like what RAMPS commonly comes with. But if he has a Melzi some other board that has a different style of header, then a different connector is appropriate.
