7.6.2
REF DES COLUMN:
The ref des
column contains the reference designation for a
specific part. These designations are assigned in
accordance with the requirements of American
National Standard Specification ANSI Y32.16. Each
reference designation index is sorted and listed
alpha/numerically according to the reference
designations in this column.
7.6.3
NAME OF PART AND DESCRIPTION
COLUMN:
This column contains the name and
descriptive information for each part. The key word
or noun is presented first, followed by the adjective
identifiers.
7.6.4
NAUTEL'S PART NO. COLUMN:
This column contains the Nautel part number assigned
to each part. This number is Nautel's drawing number
for Nautel manufactured parts, Nautel's configuration
control number for assemblies that are under
configuration control management or Nautel's
inventory management number for purchased parts.
7.6.5
JAN/MIL/OEM PART NO. COLUMN:
This column contains an original equipment
manufacturer's part number for a part. A single part
number is listed for each part, even though there may
be more than one known manufacturer. The listed
number is Nautel's usual or preferred choice. A
JAN/MIL number has been assigned as the
manufacturer's part number, where practical, to assist
the user in finding a suitable replacement part. The
use of this number does not restrict Nautel from
selecting and using commercial equivalents, where
their use will not degrade circuit operation or
reliability, during manufacture.
7.6.6
X/Y GRID COLUMN:
Ref Des Indexes
for printed wiring boards with a high parts density
have an X/Y grid column. This column contains an
alpha/numeric grouping that is keyed to an X/Y grid
on the item's assembly detail drawing. This
information is provided as an aid to locating parts on
printed wiring boards.
7.6.7
OEM CODE COLUMN:
This column
contains a five digit coded group as the original
equipment manufacturer's (OEM) identifier. The
code was extracted from Cataloging Handbook
H4/H8 - Commercial and Government Entity (Cage)
Code. Manufacturers that were not listed in the
catalog when this listing was compiled have been
assigned a unique five letter code. This code is
assigned arbitrarily and has no other significance.
The manufacturers identified for parts that have JAN
or MIL part numbers are Nautel's normal supply
source for that part.
NOTE
OEM code 37338 is listed for parts manufactured by
Nautel or to a Nautel control drawing. United States
of America customers should refer all replacement
part orders to Nautel Maine Incorporated (OEM code
57655).
