Good Brian, more arguments still for me to stop brass pins here. The wire maker and also the pin maker are of course fond of brass, but in our case (fighters)I'm always suspicous  when Zn comes up. Designed a connector body for Train Safety systems (for living on ground between rails) and had to make them in brittish marine bronze. After 10 years they have changed nulla in this tough environment. If they are stubborn here, I will set Brian on them.

IMHO, brass in contact with a solder wave is a big no-no. Just 0,001% of
Zn in your solder can render it fit for the scrap heap. As others have
said, a Ni overplate will stop the zinc leaching into the solder, but Ni
is not easy to solder unless you use a fairly active
hydrochloride-activated flux. And remember that if the pin is a push-fit
in the hole, the Ni may be abraded off, leaving the brass naked. My
suggestion: use some form of hot-tinned bronze rather than brass.
