Part Numbering Scheme

[rossh]

I'm looking for any info on existing part-numbering schemes. I would rather adopt an existing one rather than reinvent the wheel. If you are using a 9 digit (xxx-xxxx-xx) type scheme I would be interested in how it's working for you and any problem areas. Simple is better from my perspective.

Thanks

We use a seven digit scheme (XXX-XXXX) with the first three digits being the significant digits:

194-XXXX : Capacitors
267-XXXX : Covers
518-XXXX : Plates
564-XXXX : Resistors

We use numbers 800-XXXX and above for assemblies.

The addition of 2 digits (-XX) would be a further improvement but at this time we have no plans to change.

why not set a scheme for utilising the type, value, tolerance,case size
for instance
c-106-05-0603 fo a cap 1uf 5% tol 0603 size?
i have not tried this system but have heard that it may work
it makes developement a breeze with engineer able to see what is available instead of having to remember numbers not associated with the part

To keep it simple I wouldn't use 9 digits if you want people too obtain useful info from the part number. I have found a simple two letter designator system followed by 3 numbers is sufficient. RS for resistors, CA for caps, VR for voltage regulator etc.. If the inventory system you use is used to its full ability then a descent description can be attached to the part number and the whole system printed for easy look-up. Good luck

Suggestion: Check with Military standards, industry standards, and government standards for part number structure or design if you happen to be dealing with any of those entities.

Both fil & buzzp are getting into the part number -vs- drawing number argument (check out thread404-15545).
If rossh is truely looking for a part number scheme then the descriptive numbers they discribed are great. But if rossh is looking for a drawing numbering system then you are looking at an entirely differant animal and the 9 digit numbering system or something similar is what he (she?) wants. Just my 2 cents.

Are you an OEM or just stocking parts for your companies use? That will make a difference. My suggestion is relevant to OEM's that are building from scratch. Thanks
