SMD marking code “QE” — 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 | |
|---|---|---|---|---|
| 1SMA5.0A | ON | — | Public marking directory | |
| BD5324FVE | ROHM* | VSOF-5 | Public marking directory | |
| BD5324G | ROHM* | SSOP-5 | Public marking directory | |
| P6SMB18CA | LITTELFUSE | DO-214AA | Public marking directory | |
| P6SMBJ220A | LITTLE | DO-214AA | Public marking directory | |
| R1114Q341B | RICOH* | SOT-143R | Public marking directory | |
| RN1325A | TOS | SOT-323 | Public marking directory | |
| RN1425 | TOS | SOT-346 | Public marking directory | |
| SM4T6V8A | ST | SOD-6 | 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.
