SMD marking code “IE” — 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 | |
|---|---|---|---|---|
| MAX6315US43D3-T | MAX* | SOT-143 | Public marking directory | |
| 2SC3722K-E | — | SOT-346 | Public marking directory | |
| CD214A-T12A | — | DO-214AC | Public marking directory | |
| P4SMAJ12A | — | DO-214AC | Public marking directory | |
| RT9167-29CBR | — | 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.
