When to Change Part Numbers
PCN Process User Guide (301945-A)
Parts and Part Numbers: E-5
The tabbed parts have the format
123456-A-00, 123456-A-01, 123456-A-02, . . . 123456-A-99
The tabbed part number is the two-digit number from 00 to 99. The core number
is the part number without the tab.
The tab number does not carry any type of intelligence. A tabbed variation will be
noted on the cable drawing or an accompanying spec, but a unique drawing will
not exist for each tabbed version. (A unique record, however, will exist in SAP for
each tabbed variation.)
The most obvious places where tabbed part numbers may be used:
• To show variations of length, as for cables, screws, etc.
• On labels derived from a single specification, e.g., an agency’s labels that
carry the same wording but in different languages.
Note:
Don’t use tabbed parts to denote memory variations of a printed circuit board
Caution:
Tabbed parts are not currently supported by the automatic, part-number issuing tools.
You must coordinate with a member of the EDA group to have these parts numbers entered into
SAP.
When to Change Part Numbers
The rules for getting new part numbers or changing revisions of a part number are
slightly different for
pre-released products
that (a) report into
multiple projects
or
products or those being developed by more than one engineer or group, or (b)
report into
single projects
or products being developed by a single engineer or
group.
Note:
Released
items follow slightly different rules. See Appendix F for documents describing
these differences. The information in this section is extracted from those documents.
