SECTION VI
REPLACEABLE PARTS
6-1 INTRODUCTION
6-2 This section contains information for ordering
replacement parts. Table 6-4 lists parts in alpha-
numeric order by reference designators and provides
the following information:
a.
Reference Designators. Refer to Table 6-1.
b. Description.
Refer to Table 6-2 for ab-
breviations.
c. Total Quantity (TQ). Given only the first
time the part number is listed except in instruments
containing many sub-modular assemblies, in which
case the TQ appears the first time the part number
is listed in each assembly.
d. Manufacturer’s Part Number or Type.
e.
Manufacturer’s Federal Supply Code Num-
ber. Refer to Table 6-3 for manufacturer’s name and
address.
f. Hewlett-Packard Part Number.
g. Recommended Spare Parts Quantity (RS)
for complete maintenance of one instrument during
one year of isolated service.
h. Parts not identified by a reference desig-
nator are listed at the end of Table 6-4 under Me-
chanical and/or Miscellaneous.
The former consists
of parts belonging to and grouped by individual as-
semblies; the latter consists of all parts not im-
mediately associated with an assembly.
6-3 ORDERING INFORMATION
6-4 Table 6-5 is a part number-national
stock number cross reference index.
The
items on this cross reference index are
source coded PAHZZ. Items that do not
appear on this cross reference index are
source coded XD and shall be procured
using the FSCM and the NPN at the near-
est wholesale level.
