That part seems to be available from Marshall Industries (www.marshall.com).

Marshall have only a very few members of the 4820P- series networks by
Bourns, and not the particular 4820P-002-472 we need, and they're
listing a lead time of 56 days to ship on the ones they do have!

Avnet have them, but in minimum qty 2000, and stock status is "call".:

The www.Bourns.com website lists a few more distributors in this area
so I'll keep looking....

In theory one could order a bag of samples direct from Bourns.  I have
three (one still lives, for now, knock on wood) machines to try to fix
though, so that's sort of beyond the "sample" status....
