Connector mfgr asks compatibility of palladium plated pins to tin-lead plated sockets

I AM WORKING ON A PROBLEM WHERE I AM MATING A PALLADIUM PLATED PIN TO A TIN/LEAD PLATED RECEPTACLE. THIS IS FOR AN AUTOMOTIVE APPLICATION. ARE THERE ANY KNOWN PROBLEMS IN HAVING A PALLADIUM TO TIN/LEAD CONTACT INTERFACE?

If the plating is thick enough, there should be no problem. This is in the platinum family so is impervious to nearly everything except wear. Now, if it is too thin, it will have pores and you will see corrosion.
