Bill, What is your application of this connector? Assuming it is a card edge connector, how many insertions are required, what is the connecor insertion force, what is the contact geometry and are they using contact lube or not, tin ( white or any other shades) may cause more problems. Also it is important to keep same plated finish ( Au-Au or Sn-Sn) on both parts ie contact fingers and contact spring. Please discuss off line if you need more details about contact reliability issues involved.
