On the datasheet it calls out **. Could you explain what this is?

Thank You for your time


It is a place holder for specification. In the case of DF13-6P-1.25DSA it is for the (50).
DF13-6P-1.25DSA(50) is gold plated vs the Tin plating of the DF13-6P-1.25DSA.

Thank You Nathan for Your very quick help.
