What is encoded in the OPN?

The OPN shows the RoHS status, the halogen status, the totally lead free status, the functional packing type and size as well as the moisture protection packing. Additionally you can see product variants in the last two digits: Every time a product doesn´t differ in its salesname or the attributes encoded in the OPN (RoHS, Halogen, Packing Type, Moisture Protection Packing and Packing Size), the designator increments.
