SMD marking code “33V” — 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 | |

| PZM33NB | PHI | SC-59/SOT346 | Public marking directory | |
| PZM33NB1 | PHI | SOT-346 | Public marking directory | |
| XC6203E572FR | TOREX* | SOT-223 | Public marking directory | |
| XC6203E572MR | TOREX* | SOT-23 | Public marking directory | |
| XC6203E572PR | TOREX* | SOT-89 | Public marking directory | |
| CHPZ33VPT | — | SOT-23 16df - 3a Chm | Public marking directory | |
| XC6104A427MR | — | SOT-23-5 | 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.
