SMD marking code “UL” — 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 | |
|---|---|---|---|---|
| SM4T24C | ST* | SOD-6 | Public marking directory | |
| 2SC3618-L | — | SOT-89 | Public marking directory | |
| P4SMAJ15C | — | DO-214AB | Public marking directory | |
| R1122N501B | — | SOT-23-5 | Public marking directory | |
| XC6127C32JNR | — | SSOT-24 | Public marking directory | |
| XC6215B492NR | — | SSOT-24 | Public marking directory | |
| XC6223E28BNR-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.
