SMD marking code “0U” — 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.

| BU4335FWE | ROHM* | VSOF-5 | Public marking directory | |
| BU4335G | ROHM* | SSOP-5 | Public marking directory | |
| MM5Z16V | FSC | SOD-523 | Public marking directory | |
| MM3Z16V | — | SOD-323 | Public marking directory | |
| R3133Q18EA | — | SOT-143 | Public marking directory | |
| XC6127N45ANR | — | SSOT-24 | Public marking directory | |
| XC6221A45BNR | — | SSOT-24 | Public marking directory | |
| XC6221C331NR | — | SSOT-24 | Public marking directory | |
| ZD16V2 | — | SOD-322 | 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.
