Ken - We've asked the same question of some of our connector suppliers
recently.  Those who have performed environmental tests with OSP's and with
immersion Au/electroless Ni indicated they passed the electrical testing, but
had evidence of corrosive attack on the entry and exit pads.  I suggest you
query your specific connector supplier.  If I understand correctly, this type
connector system is dependent on the presence of tin/lead to function as an
insertion lubricant, as well as provide a gas tight seal to the connection
after assembly.

Regards - Kelly
