SMD marking code “9S” — 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.

| BZT52C24S | DIODES | — | Public marking directory | |
| RN5RF19AA | RICOH* | SOT-23-5 | Public marking directory | |
| BZT52-C24LP | — | DFN1006-2 | Public marking directory | |
| XC6127C41ENR | — | SSOT-24 | Public marking directory | |
| XC6127N41KNR | — | SSOT-24 | Public marking directory | |
| XC6221A241N | — | SSOT-24 26vn VR4 5a Tor | Public marking directory | |
| XC6221A241NR | — | SSOT-24 | Public marking directory | |
| XC6223B391BNR-G | — | SSOT-24 26vn VR4 5a Tor | Public marking directory | |
| XC6223B391NR-G | — | SSOT-24 | 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.
