Questions

Is there a KiCad symbol and footprint for the USBF129-I/SN?

Yes. The symbol is EasyEDA_Cloud:USBF129-I_SN 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 USBF129-I/SN?

SOIC-8, with 8 pins. Its footprint is drawn on this page.

Where is the USBF129-I/SN datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the USBF129-I/SN?

JLCPCB lists it as part C625033, with 10 in stock; the sellers' links on this page open their listings.

What can replace the USBF129-I/SN?

Parts like it in the library: the LE25U20AMB-AH by onsemi, the LE25U20AQGTX by onsemi, the LE25W81QES00-AH-1 by onsemi and the LE25U40PCMC-AH by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
