I might comment that I have substituted
various Shimano made cassettes with various
Shimano shifters and crank sets and even made
up "custom" cassettes using Shimano parts
taken from other Shimano cassettes. To data
they have all shifted with no problems,
assuming of course that one doesn't try to
mix numbers of sprockets, i.e. don't mix 7
speed and 9 speed, for example.

I have compiled some info on this, and
especially the 10S narrow casette with
"direction" (?), that seems to work with
105, Ultegra and DA.

Note: The table is probably very incomplete!

BTW except for "direction" which I don't
understand, what does the "CN-" prefix
mean? China?

I'm not sure what some of your dimensions are intended to show but you
might be interested in
http://www.bike.bikegremlin.com/2015...ear-sprockets/
which shows the sprocket thickness and spacing for cassettes ranging
from 6 to 11 cogs.
