SMD marking code “63” — 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.

| BAS40W | PHI | SOT-23 | Public marking directory | |
| BAS40W | PHI | SC-70/SOT323 | Public marking directory | |
| CHDTC144VMPT | — | SOT-723 18ta - 3a Chm | Public marking directory | |
| CSA1163 | — | SOT-23 | Public marking directory | |
| CSA1163G | — | SOT-23 | Public marking directory | |
| CSA1163L | — | SOT-23 | Public marking directory | |
| XC6217C34ANR | — | SSOT-24 | Public marking directory | |
| XC6221D11BNR | — | 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.
