What makes you think the MPD ones from Digikey are different than the
Marinco ones? Marinco doesn't claim their's are stainless (and I doubt
they are, stainless doesn't make a good electrical contact), only
"corrosion resistant materials."

The MPD ones are nickle plated brass, which is a "corrosion resistant
material."

They sure look identical, and it's a pretty unique design. Both have
the locking feature. The same holds for the plugs sold by both. I
suspect they come from the same Chinese source.
