SMD marking code “UU” — 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 | |
|---|---|---|---|---|
| 3SK226 | TOS | SOT-143 | Public marking directory | |
| BAR88-02L | INFINEON | — | Public marking directory | |
| BD45382G | ROHM* | SSOP-5 | Public marking directory | |
| SM4T36C | ST* | SOD-6 | Public marking directory | |
| P4SMAJ20C | — | DO-214AC | Public marking directory | |
| PT7M6314US37D3 | — | SOT-143 | Public marking directory | |
| XC6127C46JNR | — | SSOT-24 | Public marking directory | |
| XC6223E35BNR-G | — | 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.
