SMD marking code “1T” — 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 | |
|---|---|---|---|---|
| 2SC3077 | TOS* | SOT-23 | Public marking directory | |
| 2SC3933 | PANASONIC* | SOT-323 16ta - 3a Pan | Public marking directory | |
| IMP161TCUS | IMP* | SOT-143 | Public marking directory | |
| MMBT3960A | MOT | — | Public marking directory | |
| UNRF2A1 | PANASONIC* | — | Public marking directory | |
| 2SD2416 | — | SOT-89 | Public marking directory | |
| R3131N44HA | — | SOT-23 | Public marking directory | |
| R3133Q27EA | — | SOT-143 | Public marking directory | |
| XC6127N43BNR | — | SSOT-24 | Public marking directory | |
| XC6217C252NR | — | SSOT-24 | 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.
