SMD marking code “7Y” — 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 | |
|---|---|---|---|---|
| 2SA1621-Y | TOS | SOT-23 | Public marking directory | |
| MA2ZV02 | PANASONIC* | SOD-123 | Public marking directory | |
| MMBR941 | MOT* | SOT-23 | Public marking directory | |
| MMBR941L | MOT | SOT23 | Public marking directory | |
| UNR212Y | PANASONIC* | SC-59 | Public marking directory | |
| R1210N571C | — | SOT-23-5 | Public marking directory | |
| UN212Y | — | SC-59 | Public marking directory | |
| XC6127C51CNR | — | SSOT-24 | Public marking directory | |
| XC6127N51HNR | — | SSOT-24 | Public marking directory | |
| XC6217D29ANR | — | 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.
