Source Code. The source code tells you how to get an item needed for maintenance, repair, or overhaul of
an end item/equipment. Explanations of source codes follow:
Code
Explanation
Stocked items; use the applicable NSN to request/requisition items with these
source codes. They are authorized to the category indicated by the code entered
in the 3rd position of the SMR code.
**NOTE: Items coded PC are subject to deterioration.
Items with these codes are not to be requested/requisitioned individually. They
are part of a kit which is authorized to the maintenance category indicated in the
3rd position of the SMR code. The complete kit must be requisitioned
and
applied.
Items with these codes are not to be requested/requisitioned individually. They
must be made from bulk material which is identified by the part number in the
DESCRIPTION AND USABLE ON CODE (UOC) column and listed in the Bulk
Material group of the repair parts list in this RPSTL If the item is authorized to you
by the 3rd position code of the SMR code, but the source code indicates it is
made at a higher level, order the item from the higher level of maintenance.
Items with these codes are not to be requested/requisitioned individually. The
parts that make up the assembled item must be requisitioned or fabricated and
assembled at the level of maintenance indicated by the source code. If the 3rd
position code of the SMR code authorizes you to replace the item, but the source
code indicates the item is assembled at a higher level, order the item from the
higher level of maintenance.
XA
- Do not requisition an "XA" coded item. Order its next higher assembly. (Also, refer to the NOTE on page 4.)
XB

XC
- Installation drawing, diagram, instruction sheet, field service drawing, that is identified by manufacturer’s part
number.
XD
- Item is not stocked. Order an "XD" coded item through normal supply channels using the CAGEC and part
number given, if no NSN is available.

Cannibalization or controlled exchange, when authorized, may be used as a source of supply for items
with the above source codes, except for those source coded "XA".
