That would be my inclination too.

This says to me "five-amp rectifier pair", especially if the K is next
to the middle lead. This strikes me as somewhat unlikely on a 72-pin
memory module; I see no reason it would want a rectifier capable of
carrying five amps.

Do you have a scanner, or some other means of getting pictures of the
two modules? I'd be happier if I could see the markings myself (not
that I could necessarily say anything even if I did, of course).
