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.

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 schematic) 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 electrolytic (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
