Most problems come down to a misread character. The rest we can usually fix if you send us the code.
Submit a missing code
Send the part number and a photo of the package. Verified codes are added to the catalogue.
Report a wrong result
Tell us the code and the capacity you actually measured and we will re-verify it.
Anything else

My IC code returns no result
Re-read the marking first. 0/O, 1/I,
5/S and 8/B account for most failed
lookups, and a worn package can lose a character entirely.
Check you are using the first line of the marking. Lot codes and date codes on the lines below are not part numbers and will never match.
Still nothing? Send it to us with a photo of the chip if you can — clear submissions get added.
The result looks wrong
Tell us the part number and what you measured, and we will re-verify the record. Second-source parts and revision reuse do happen. Report a correction.
The search box is not loading anything
The live lookup needs JavaScript and a connection to the catalogue service. If it stays blank, the IC code list is plain HTML and works regardless — every part is reachable through it.
Do you have an API?
Not a public, documented one. If you have a genuine integration in mind, get in touch and describe it.
Can I use this data in my own project?
Individual lookups, freely. Bulk copying of the catalogue is not permitted — see the Terms. For licensing, email us.
The catalogue currently holds 16,776 part numbers and grows as submissions are verified.
