When looking up part numbers for LED products from [OSRAM](https://www.digikey.com/en/supplier-centers/osram-opto-semiconductors), you may see the “-S” suffix after the end of orderable part numbers such as [KG DELMS1.22-PHQI-24-E6L6-20-S](https://www.digikey.com/en/products/detail/osram-opto-semiconductors-inc/KG-DELMS1-22-PHQI-24-E6L6-20-S/10433456).

OSRAM has confirmed that this “-S” is internal to Osram and has no effect on the part.

Hi Kevin,

This looks like an answer to a question I probably asked long ago, but don’t remember. Can you show me my original inquiry? I must have a part number uncertain on a parts list somewhere.

Thank you.
