SMD marking code “NO” — 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

| 2SA1213PT-O | TOS* | SOT-89 | Public marking directory | |
| 2SC3138-O | TOS* | SC-59 | Public marking directory | |
| 2SK1592 | — | SOT-89 | Public marking directory | |
| AAT3526ICX-2.32-200 | — | SOT-143 | Public marking directory | |
| ASM811JEUSF | — | SOT-143 | Public marking directory | |
| KRC113S | — | SOT-23 | Public marking directory | |
| KRC413 | — | SOT-323 | Public marking directory | |
| KRC413E | — | SOT-490 | Public marking directory | |
| KRC413V | — | — | 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.
