Sourcing and compliance notes
REACH Article 33 applies: the part contains Lead (CAS-No. 7439-92-1) above the 0.1% threshold, so the downstream user declaration is needed if you're integrating into EU-market equipment. Group code R2SC and product group 4Q30 are Siemens internal classification tags — useful for cross-referencing in their ordering tool or when pulling a BOM from a legacy project archive.
