Yes, ID-11 and D-76 really are the same, as are NACCO
Super 76 concentrate.
I usually use ID-11 or Nacco super 76, I try to use Nacco
because like
ILFOTEC-HC it's a highly concentrated liquid, that you
make a stock solution
from, so A bottle goes along way.

They are not quite the same nor are they the same as the
published formulas. I have no idea how much, if any, this
affects the performance.
NACCO Super 76 is a Phenidone and hydroquinone
developer. I think years ago it was similar to Kodak D-76
but is no longer so. It is probably closer to Ilford
Microphen than to either of the above. Microphen is a D-76
_type_ developer using Phenidone and hydroquinone in a
buffered solution. See the NACCO MSDS for confirmation.
Ilfotec-HC is probably similar to Kodak HC-110 but may
not be identical. It is intended to serve the same purpose,
namely as a highly concentrated general purpose film
developer.
The problem with MSDS is that they are legal rather
than technical or scientific publications and can obscure
the contents as much as elucidate them.
