SMD marking code “0Q” — 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 | |
|---|---|---|---|---|
| BU4331F | ROHM* | SOP-4 | Public marking directory | |
| BU4331FWE | ROHM* | VSOF-5 | Public marking directory | |
| BU4331G | ROHM* | SSOP-5 | Public marking directory | |
| PD3Z284C10 | DIODES* | PowDI323 | Public marking directory | |
| Z0Q | DIODES | — | Public marking directory | |
| R3131N40AA | — | SOT-23 | Public marking directory | |
| R3133Q14EA | — | SOT-143 | Public marking directory | |
| R5326N015B | — | SOT-23-6 | 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.
