These are common as dirt. But all appear to be proprietary. They really shouldn't be called SMD marking codes, as there are plenty of other components that need to be looked up. | These are common as dirt. But all appear to be proprietary.

Chip golf.
List
- https://www.eevblog.com/forum/repair/unknown-dc-dc-chip-of-si-9110-differential-probe/ - +12 and -12 switcher. No feedback divider. Turns out to be the max743
- https://www.eevblog.com/forum/projects/identify-an-old-(mid-1970s)-10-bit-adc/ - Old adc module. More pins than usual adcs of the 70's. Turns out to be the ADC-10Z.
- https://www.eevblog.com/forum/repair/cant-find-this-ic-its-on-msi-optix-ag32c-pc-monitor/ Basic understanding of HDMI connectors leads to the answer, that of a TVS diode array. "If you know what to expect for a given circuit". It is not stated how the particular code was found, and searching ic mark websites does not show this result. Project: Find a similar array on a scrap HDMI connector circuit.
- https://www.eevblog.com/forum/beginners/help-identify-these-possibly-rfmicrowave-components/ - check russian internet for russian chips.
- https://www.eevblog.com/forum/beginners/mystery-relic-microchip-sot-style-chip-identify-please-looked-everywhere/ mitsumi not microchip
Identify that Switch/Connector
- https://www.eevblog.com/forum/projects/searching-for-a-particular-square-illuminated-push-button/ - typical intercom, plastic square buttons with text labels on the inside.
- https://www.eevblog.com/forum/repair/replacement-for-fluke-845ab-opr-switch/ - 3d print, or otherwise make your own replacement.

Package Code Search
These are common as dirt. But all appear to be proprietary. They really shouldn't be called SMD marking codes, as there are plenty of other components that need to be looked up.
- http://www.smdmark.com/en-US/search/code?id=AAA - This one you can use without JS, just add the code where appropriate in the URL. Some results require logging in...
- http://markingcodes.com/search/c/AAA - Same as previous for adding code. Shows a bit more results, but requires JS to change pages.
- Where is the public wiki search? Too much greed, too many people trying to monetize something which should just be a database.
