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:

Replaceable Parts List Index Part Number Page

Table 7-1. Transmitter 994 9283 001 7-2

Table 7-2. Control Cabinet 992 9244 002 7-3

Table 7-3. Controller Board 992 8344 002 7-6

Table 7-4. PA Cabinet 992 9400 002 7-7

Table 7-5. PA Amplifier 994 7894 002 7-9

Table 7-6. PA Amplifier Board 992 7904 002 7-10

Table 7-7. Output Cabinet 992 9450 001 7-12

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 equiva

-

lent 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.).

NOTE: Inside the individual tables some standard conventions are used:

• A # symbol in front of a component such as #C001 under the REF. SYMBOLS/EXPLANATIONS col-

umn 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 pur-

chased 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 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.
