8. REPLACEABLE PARTS LIST:
This section lists and describes the parts located in Standard 8310 Series Programmable Attenuator Units
(P/N 193-70XX-X). The Replaceable Parts Lists (RPL) are intended for use in identifying, locating, and requisitioning
assemblies and components for the Model 8310.
8-1 UNDERSTANDING REFERENCE DESIGNATORS:
All assemblies and electrical parts are identified by standard
reference designators (resistors R1, for example). Reference designators are used in parts lists and on parts
identification drawings. The title of a parts list or drawing contains the reference designator or the assembly or
subassembly to which it applies. The designators in the parts list, as a prefix, but omitted from the list to make it
easier to locate a specific part. To complete a reference designator in a parts list, precede the designator for the
specific part (DS1, for example) with the designator in the title (A6, for example) to form a complete reference
designator for the part (in this case, A6DS1).
8-2 ORDERING INFORMATION:
When ordering parts from Weinschel, please include the following information:
•
Aeroflex / Weinschel part number.
•
Description of the component or part.
•
Model and serial number of the instrument.
•
Assembly number and assembly revision (if any) from the assembly
(this information is on the component side of the PCB).
8-3 DRAWING NUMBER:
The Aeroflex / Weinschel part number consists of a basic number with a dash number. The
basic number should cross reference to a drawing number for most of the items. For those items that do not have a
drawing number, the manufacturers part number is provided.
8-4 REPLACEABLE PARTS LIST (RPL):
This RPL contains a breakdown of the instrument into its major assemblies
and detailed parts. The following paragraphs describe the contents of each column of the RPL.
8-4.1 REFERENCE DESIGNATOR:
This column contains reference designations arranged in alphanumerical
sequence. The letters A thru Z have precedence, followed by numerals 0 thru 9. In addition to the reference
designators that are listed, some mechanical parts are also listed. These items lack reference designators and are
included because they are considered subject to wear and/or breakage, or because they are custom (non-standard)
hardware or parts that might become lost or damaged. This column contains the word N/A for those items or parts not
having a reference designator.
8-4.2 DESCRIPTION:
This column contains the nomenclature located in the title block of the engineering drawing by
the designing activity. The noun name is listed first, followed by modifiers and descriptive information to completely
identify the part or assembly.
8-4.3 PART NUMBER:
This column contains the Weinschel part number assigned to an assembly, sub-assembly, or
detailed part. This also includes Weinschel numbers for specification control, source control, and altered items
drawings.
8-4.4 VENDOR PART NO.:
This column contains manufacturers part numbers for those parts Weinschel purchases,
as off the shelf items and assigns Weinschel part numbers for internal control only. These parts may be ordered
through the manufacturer or through Weinschel by the Weinschel part number.
8-4.5 CAGE CODE:
This column provides the Commercial and Government Entity (CAGE) code on the same line as
the applicable part number. Codes, names, and addresses of venders with an assigned CAGE are listed in Cataloging
Handbook H4-1 and H4-2. Vendors that have not been assigned CAGE codes by the government are identified by the
word NONE in this column. The names and addresses of these venders can be obtained from Weinschel. Part
numbers that have no CAGE numbers listed are manufactured or altered by Weinschel.
8-4.6 ASSEMBLY AND COMPONENT LOCATION:
The assembly/component location and schematic diagrams for
the different 8310 series models are located in rear of this manual by the drawing number. Drawing find numbers
have also been included to help locate components or hardware.
