8.6.2 REFEREBCE DESIGNATION
COLUMN:
The reference designation 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.
8.6.3 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.
8.6.4 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.
8.6.5 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.
8.6.6 X/Y GRID COLUMN:
Reference
Designation 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.
8.6.7 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).
