SMD marking code “1X” — 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 | |
|---|---|---|---|---|
| 2SC2845 | TOS* | SC-59 | Public marking directory | |
| BF822 | PHI | SOT-23 | Public marking directory | |
| MMBT930L | MOT | SOT23 | Public marking directory | |
| UNRF2A5 | PANASONIC* | — | Public marking directory | |
| MM3Z6V8 | — | SOD-323 | Public marking directory | |
| R1210N411C | — | SOT-23-5 | Public marking directory | |
| XC6127N49BNR | — | SSOT-24 | Public marking directory | |
| XC6217C282NR | — | 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.
