SMD marking code “2Z” — 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 | |
|---|---|---|---|---|
| 2SC4417 | TOS* | SOT-323 16ta - 3a Pan | Public marking directory | |
| BAS70-04 | PHI | SOT23 | Public marking directory | |
| MMBT6520 | MOT | SOT-23 | Public marking directory | |
| UNRF2AM | PANASONIC* | — | Public marking directory | |
| MM3Z39V | — | SOD-323 | Public marking directory | |
| R1210N221D | — | SOT-23-5 | Public marking directory | |
| TCMM3Z3V0B | — | SOD-323F | Public marking directory | |
| XC6127N53CNR | — | SSOT-24 | Public marking directory | |
| XC6221C37BNR | — | 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.
