SMD marking code “BO” — 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 | |
|---|---|---|---|---|
| 2SA1200-O | TOS* | SOT-89 | Public marking directory | |
| 2SC5342U-Q | TOS* | SOT-323 16ta - 3a Auk | Public marking directory | |
| 2SC5342UF-Q | TOS* | SOT-323F 18ta - 3a Auk | Public marking directory | |
| BCW61AR | PHI | SOT23 | Public marking directory | |
| UDZ18B | DIODES* | SOD-323 | Public marking directory | |
| GS6332UR15D2 | — | SOT-23 | Public marking directory | |
| KTA1660-O | — | SOT-89 | Public marking directory | |
| SiP6332R15D2 | — | SOT-23 | Public marking directory | |
| V6300OSP5B | — | SOT-23-5 | 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.
