Unit Supply . . .
The relationship may be interchange-
able, substitutable or a combination of
both. All family members will have a
phrase code (PC) that points them to
the master NSN. How the items are
selected for issue is based on the order
of use (OOU) file.
Interchangeable items
can be sub-
stituted for each other with little or no
adjustment required. Their perfor-
mance, reliability and maintainability
are identical
Substitutable items
aren’t identical
to each other, but are enough alike
that they can be substituted for one
another under specific conditions and
applications.
When an item manager decides
there is a relationship among
similar items, he establishes an
I&S family. AN I&S family consists
of one master NSN (the head of the
family) and one or more related NSNs.
To find out more about how I&S
works, go to the LOGSA I&S home
page at:
and click on the DOD I&S Training
Module.
You can also click on the LOGSA
I&S problem report form. This report
can be filled out on-line and sub-
mitted to the LOGSA I&S team for
review. You can use this I&S problem
report any time you think there is
an I&S problem. Report the problem
as soon as you can so it can be
corrected before it becomes an even
bigger problem.

As you check out some new parts that came in to
your supply room, you notice that some of the
parts are not exactly what you ordered. The NSNs
are different.
But, before you excess those parts and reorder the original NSNs, using advice
code
2B - Do Not Substitute
, check ’em out in the FED LOG Army Master
Data File (AMDF). Those new parts may be the result of a process called
Interchangeability and Substitutability (I&S).
I&S provides a way to get rid
of duplicate items, or items with
a limited range of performance,
reliability and maintainability
characteristics, in favor of items
that don’t have limitations.
i've got to figure
