How these mappings are compiled: from public SMD marking directories and from our own stock records (marked Stock-record verified). We keep the original reference of every row internally so any mapping can be traced on request.

Markings are indicative only: the same code can denote different parts across manufacturers and packages. Always confirm with the physical batch marking and the original datasheet.

* Manufacturer derived from the part-number family (some directory entries carry no manufacturer) — treat it as a lead, not a datasheet fact.
