Guide to Using Harris Parts List Information
The Harris Replaceable Parts List Index portrays a tree structure with the major items being leftmost in the index. The
example below shows the Transmitter as the highest item in the tree structure. If you were to look at the bill of
materials table for the Transmitter you would find the Control Cabinet, the PA Cabinet, and the Output Cabinet. In the
Replaceable Parts List Index the Control Cabinet, PA Cabinet, and Output Cabinet show up one indentation level
below the Transmitter and implies that they are used in the Transmitter. The Controller Board is indented one level
below the Control Cabinet so it will show up in the bill of material for the Control Cabinet. The tree structure of this
same index is shown to the right of the table and shows indentation level versus tree structure level.
Example of Replaceable Parts List Index and equivalent tree structure:

The part number of the item is shown to the right of the description as is the page in the manual where the bill for that
part number starts. Inside the actual tables, four main headings are used:
•
Table #-#. ITEM NAME - HARRIS PART NUMBER - this line gives the information that corresponds to the
•
Replaceable Parts List Index entry;
•
HARRIS P/N column gives the ten digit Harris part number (usually in ascending order);
•
DESCRIPTION column gives a 25 character or less description of the part number;
•
REF. SYMBOLS/EXPLANATIONS column 1) gives the reference designators for the item (i.e., C001, R102, etc.)
that corresponds to the number found in the schematics (C001 in a bill of material is equivalent to C1 on the sche-
matic) or 2) gives added information or further explanation (i.e., "Used for 208V operation only," or "Used for HT
10LS only," etc.).
Inside the individual tables some standard conventions are used:
•
A # symbol in front of a component such as #C001 under the REF. SYMBOLS/EXPLANATIONS column means
that this item is used on or with C001 and is not the actual part number for C001.
•
In the ten digit part numbers, if the last three numbers are 000, the item is a part that Harris has purchased and has
not manufactured or modified. If the last three numbers are other than 000, the item is either manufactured by Harris
or is purchased from a vendor and modified for use in the Harris product.
•
The first three digits of the ten digit part number tell which family the part number belongs to - for example, all elec-
trolytic (can) capacitors will be in the same family (524 xxxx 000). If an electrolytic (can) capacitor is found to have
a 9xx xxxx xxx part number (a number outside of the normal family of numbers), it has probably been modified in
some manner at the Harris factory and will therefore show up farther down into the individual parts list (because
each table is normally sorted in ascending order). Most Harris made or modified assemblies will have 9xx xxxx xxx
numbers associated with them.
The term "SEE HIGHER LEVEL BILL" in the description column implies that the reference designated part number
will show up in a bill that is higher in the tree structure. This is often the case for components that may be frequency
determinant or voltage determinant and are called out in a higher level bill structure that is more customer dependent
than the bill at a lower level.
