SMD marking code “3P” — 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 | |

| CMDZ22L | CSC CENTRAL SEMIC.CORP. | SOD-323 | Public marking directory | |
| FMMT2222AR | FERRANTI | SOT-23 | Public marking directory | |
| FMT2222AR | ZETEX | SOT-23R | Public marking directory | |
| RQ5RW33CA | RICOH* | SOT-143R | Public marking directory | |
| R3131N29HC3 | — | SOT-23 | Public marking directory | |
| R3133Q43EA | — | SOT-143 | Public marking directory | |
| XC6127N37DNR | — | SSOT-24 | Public marking directory | |
| XC6217D222NR | — | SSOT-24 | Public marking directory | |
| XC6223A371NR-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.
