hi tom,                                                                       
                                                                               
 A reference which we keep using as a guide is found in mil-f-14072b,          
 para. 3.13 and the table of "compatible couples".                             
 There are also solderability issues associated with gold plated lugs.         
                                                                               
 regards,
