NO!  The DD11-DF is meant to go in BA11-F chassis (21" tall ones) and
the DD11-DK is meant to go in BA11-K chassis (10.5" tall ones).  The
difference is the length of the power harness.  The DF is long and the
DK is short.

There are also DD11-CF and DD11-CK backplanes which are 4 slot versions
of the above.
