6-5. HP PART NUMBER ORGANIZATION
6-6. Following is a general description of the HP part number system.
6-7. Component Parts and Materials
6-8. Generally, the prefix of HP part numbers identifies the type of device. Eight digit part
numbers are used, where the four-digit prefix identifies the type of component, part, or
material and the four-digit suffix indicates the specific type. Following is a list of some of the
more commonly used prefixes for component parts. The list includes HP manufactured parts
and purchased parts.
