SMD marking code “73T” — 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 | |
|---|---|---|---|---|
| BAS70 | NXP | SOT-23 | Public marking directory | |
| BAS70 | PHI | SOT23 | Public marking directory | |
| BAS70-07 | INFINEON | SOT-143 | Public marking directory | |
| BAS70W | PHI | SOT-323 16dc - 3a PhM | Public marking directory | |
| BAS70W | PHI | SC-70/SOT323 | Public marking directory | |
| XC6111A425MR | TOREX* | SOT-23-5 | 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.
