SMD marking code “L21” — candidate parts
5 candidates2 with manufacturer
Small packages rarely print the full part number. The marking below maps to these part numbers — verify against the package, pin count and the manufacturer's datasheet before ordering.
Candidate part numbers
| Part number | Manufacturer | Package | Mapping basis | |
|---|---|---|---|---|
| BAS31 | FSC | SOT-23 16dl - 3a Nsc | Public marking directory | |
| BAS31 | PHI | SOT23 | Public marking directory | |
| 82C21-AE3-5 | — | SOT-23 16vdb VD7 3a Utc | Public marking directory | |
| GS810C21EUA | — | SOT-23 | Public marking directory | |
| SJ73L21S | — | SOT-23 16vda VD6 3b Auk | Public marking directory |
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.
