Using partmgr to Update or Get a New Part Number

PCN Process User Guide (301945-A)

Using and Getting Part Numbers: 3-5

Specify whether the part is off the shelf (i.e., purchased), custom made, or

documentation only.

Documentation includes assembly drawings, schematic drawings,

specifications, revision registers, board modification history, and rework

instructions.

Basically, documentation includes part numbers that do not represent a

physical material that can be purchased, stocked, or assembled into a unit. So,

for example, part numbers for program code need to be included in the list of

documentation parts, but programmed parts do not. Specifications and

drawings are mostly documentation, unless they represent an actual part.

Specify a 3-character alphanumeric class code for your part.

If the part is documentation only, the class codes were listed before

the

partmgr

asks you for the type of part.

If the part is off the shelf or custom made, you can enter the class

code (if you know it) or press Return to display a list of classes.

Note:

Class codes are assigned to individual component engineers, so they determine which

component engineer sees your new part number request. See

Class Codes (Material Groups)

page E-12 for lists and descriptions of the class codes. (They are also used in some legacy part

numbers.)

Enter the part description when you are prompted.

The description can have as many as 40 characters, and should follow the

format shown in the example prompt, e.g., for

|........10........20........30........40|

RES VALUE OHM TOLERANCE WATTAGE PACKAGE

enter:

RES 10K OHM 5% 1/4 W 0805

Proceed to the questions about each potential vendor: name, vendor’s

part number, URL, availability, etc., and answer them according to the

following guidelines:

• For purchased parts, you need to name a vendor, but the component

engineer assigned to the class code for your new part usually decides the

source.
