Yes. It is important that you get them so. And once you have them, please remember to take care of the point that I mentioned in my last post regarding soldering the male header. Unlike a round connector ( like the ones from Amphenol ) the self aligning property of a straight row of pins in a relimate is very limited. Thus for proper contact it is very important that all pins LINE up perfect.

In fact if you notice carefully, the plastic used in TVS connectors have a relatively higher melting point as compared to the fake ones which melt like butter. And the wires used in the fake ones have conductors that simply refuse to get soldered. Who said electronics is fun ?!
