When looking at the LW P4SG series of LEDs from OSRAM, you may see a suffix “-ZI” at the end of the part number. The details of this suffix are not frequently published in the datasheet, such as LW P4SG-V2AB-JKPL-1-ZI
- “-ZI” means that
Z calls out RoHS compliant
I calls out that it’s an in-house chip which has no bearing on form, fit or function.
