Gold vs tin across the series
Within the same 60619 base number the 60619-4 offers the same 14-20 AWG wire range and crimp termination but with tin contact finish — the 60619-5's gold plating suits applications requiring higher mating cycle life or corrosion resistance. The 60617-6 and 60617-5 are 18-24 AWG sockets in the same Commercial MATE-N-LOK series with identical 30.0µin gold plating — the wire gauge difference is the primary selection axis.
