SMD marking code “T23” — 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 | |
|---|---|---|---|---|
| PDTA114TU | NXP | SOT-323 16ta - 3a PhM | Public marking directory | |
| PDTA114TU | PHI | SC-70/SOT323 | Public marking directory | |
| PDTA123JT | PHI | SOT-23 16ta - 3a PhM | Public marking directory | |
| PDTA123JT | PHI | SOT23 | Public marking directory | |
| TK71523S | TOKO* | SOT-23 16cj VR1 3d Tok | Public marking directory | |
| R1162N231D | — | SOT-23-5 | Public marking directory | |
| XC31BPN23AM | — | SOT-23-5 | Public marking directory | |
| XC31BPN23DM | — | USP-6B | 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.
