That's because they haven't been. :-)
I actually have an interesting reverse behaviour, where I can get a
DELQA to freeze on my 11/93 running RSX, while a DEQNA will continue
(I do suspect it is because the extra care DECnet takes to keep a QNA
ticking which saves me, but anyway... Interesting...)
And to answer the OP: the cab kits are the same, modulo the letters
under the connector.
