LM185-ADJ: 883 not marked on part

Part Number: LM185-ADJ

Hello

I have in front of me what looks like

national semi

LM185BH

date code 0917

But the MFR COC that I got with it reads LM185BH/883

Is it possible that this part is a LM185BH/883 but that national semi just didn't mark the 883 on the part?

Also, does anybody know if national semi even offered a LM185BH without the mil std 883 processing level?

Because if it wasn't, than regardless of whether this part in front of me is marked 883 or not, I would know that this is a LM185BH/883 since it couldn't be anything else.

thank you

Hello Yoichi,

According to our archives, starting in 1999, the LM185BH/883 marking was simply "LM185BH". Note that there should also be a "Q" on the package that is between the part number and the datecode.

Wow that definitely answers the question. Any chance we can see that small part of the archives where that information is written?

thank you
Andrew

Hello Andrew,

Our archive is just an excel spreadsheet that shows when marking changes were made. The information is coded for our systems and you would not be of use to anyone without training in the coding system.

hi Kirby

one last question. Could you advise what the Q between the part number and date code means?

thank you
Andrew

The Q indicates that it is manufactered, processed, tested and qualified per the mil standards MIL-PRF-38535 and MIL-STD-883.
