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.
