Overview
The OPA129U is an operational Amplifier made by Texas Instruments in a SOIC-8 package with 8 pins. 1 1MHz 2.5V/us SOIC-8 Operational Amplifier ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:OPA129U, from EasyEDA) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C56181). 1 open-source board in 1 repository on GitHub use it.

Is there a KiCad symbol and footprint for the OPA129U?
Yes. The symbol is EasyEDA_Cloud:OPA129U and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the OPA129U?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where can I order the OPA129U?
JLCPCB lists it as part C56181, with 0 in stock; the sellers' links on this page open their listings.
What can replace the OPA129U?
Parts like it in the library: the LM358D by onsemi, the LM2904D by onsemi, the NE5532D by Texas Instruments and the LM358D by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the OPA129U?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
