SMD marking code “2V” — 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 | |
|---|---|---|---|---|
| KST64 | FSC | SOT-23 | Public marking directory | |
| MMBTA64 | FSC | SOT-23 | Public marking directory | |
| RQ5RW28CA | RICOH* | SOT-143R | Public marking directory | |
| SMBTA64 | INFINEON | SOT-23 16ta - 3a Inf | Public marking directory | |
| R3133Q39EA | — | SOT-143 | Public marking directory | |
| UMZ33K | — | SOT-343 | Public marking directory | |
| XC6127N47CNR | — | SSOT-24 | Public marking directory | |
| XC6221C34BNR | — | 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.
