SMD marking code “2N3904” — 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 | |
|---|---|---|---|---|
| T92 | PHI | SOT23 | Public marking directory | |
| T92P | TE* | SOT23 | Public marking directory | |
| p1A | PHI | SOT89 | Public marking directory | |
| 1AM | — | SOT23 | Public marking directory | |
| N71 | — | — | Public marking directory | |
| R1A | — | SC70 | Public marking directory | |
| R1G | — | SOT23 | Public marking directory | |
| U92p | — | SOT23 | Public marking directory | |
| U94 | — | SOT143 | Public marking directory | |
| t1A | — | SOT23 | 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.
