You seem to have discontinued PTH04T221WAZ while PTH04T221WAS is still available. The PACKAGING INFORMATION table in the datasheet says *WAS has SNPB balls, but another column says "RoHS (In Work) & Green (In Work)".
Digikey and others says that part is not RoHS compliant.
1. Do you claim that this part is somehow exempt from the lead free requirement of RoHS?
2. If so, exactly what exemption do you refer to?
3. What is your definition of the term "In Work" that is used in this table?
Best regards
