SMD marking code “KT2” — candidate parts
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 | |
|---|---|---|---|---|
| 2SC4407-2 | TOS* | MCP 16ta - 3a San | Public marking directory | |
| BAS19 | FSC | SOT-23 16dc - 3a Di | Public marking directory | |
| BAS20 | PHI | SOT-23 | Public marking directory | |
| BAS21 | MCC | SOT-23 | Public marking directory | |
| KT3 | DIODES | — | Public marking directory | |
| 2SC4270-2 | — | SOT-23 | Public marking directory | |
| BAS19W | — | SOT-323 | Public marking directory | |
| BAS20W | — | SOT-323 | 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.
* Manufacturer derived from the part-number family (some directory entries carry no manufacturer) — treat it as a lead, not a datasheet fact.
