| DTC123JKA | RHOM | SOT-346 16ta - 3a Rhm | Public marking directory | |
| DTC123JUA | MCC | UMT3 16ta - 3a Rhm | Public marking directory | |
| DTC123JUA | MCC | SOT-323 | Public marking directory | |
| DTC123JM | — | VMT3 18ta - 3a Rhm | 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.
