SMD marking code “1Z” — 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 | |
|---|---|---|---|---|
| BAS70-06 | PHI | SOT-23 | Public marking directory | |
| MMBT6517 | MOT | SOT-23 | Public marking directory | |
| UNRF2A7 | PANASONIC* | — | Public marking directory | |
| MM3Z8V2 | — | SOD-323 | Public marking directory | |
| TCMM3Z2V7B | — | SOD-323F | Public marking directory | |
| XC6127N53BNR | — | SSOT-24 | Public marking directory | |
| XC6217C302NR | — | 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.
