SMD marking code “RO” — 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 | |
|---|---|---|---|---|
| 2SA1204-O | TOS | SOT-89 | Public marking directory | |
| MCP101T-475I | MIC* | SOT-23 | Public marking directory | |
| PDZ20B | NXP | SOD-323 | Public marking directory | |
| 2SA1024-O | — | SOT-89 | Public marking directory | |
| 2SA1664-O | — | SOT-89 | Public marking directory | |
| 2SC2715-O | — | SC-59 | Public marking directory | |
| CHT848BWPT-Q | — | SOT-323 16ta - 3a Chm | Public marking directory | |
| KTA1664-O | — | SOT-89 | Public marking directory | |
| P4SMA13C | — | DO-214AC | 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.
