SMD marking code “0W” — 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 | |
|---|---|---|---|---|
| BU4337F | ROHM* | SOP-4 | Public marking directory | |
| BU4337FWE | ROHM* | VSOF-5 | Public marking directory | |
| BU4337G | ROHM* | SSOP-5 | Public marking directory | |
| MM5Z18V | FSC | SOD-523 | Public marking directory | |
| MM3Z18V | — | SOD-323 | Public marking directory | |
| R1210N301C | — | SOT-23-5 | Public marking directory | |
| ZD18V0 | — | 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.
