SMD marking code “TU” — 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

|---|---|---|---|---|
| BD45461G | ROHM* | SSOP-5 | Public marking directory | |
| P6SMB91C | ON* | DO-214AA | Public marking directory | |
| SM4T220 | ST* | SOD-6 | Public marking directory | |
| ASM162JEUS | — | SOT-143 | Public marking directory | |
| BAT54TCPT | — | SOT-416 16dg - 3a Chm | Public marking directory | |
| MM3Z16VS | — | SOD-323 | Public marking directory | |
| P4SMAJ9.0C | — | DO-214AC | Public marking directory | |
| R1122N481B | — | SOT-23-5 | Public marking directory | |
| XC6127C46HNR | — | SSOT-24 | Public marking directory | |
| XC6215B262NR | — | SSOT-24 | Public marking directory | |
| XC6223D35BNR-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.
