Questions

Is there a KiCad symbol and footprint for the WS2801S?

Yes. The symbol is EasyEDA_Cloud:WS2801S and the footprint Package_SO:SOIC-14_3.9x8.7mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the WS2801S?

SOP-14, with 14 pins. Its footprint is drawn on this page.

Where is the WS2801S datasheet?

Worldsemi publishes it: the Datasheet link on this page opens it.

Where can I order the WS2801S?

JLCPCB lists it as part C114580, with 3,068 in stock; the sellers' links on this page open their listings.

What can replace the WS2801S?

Parts like it in the library: the TPS61050YZGR by Texas Instruments, the AAT3176IDH-T1 by Skyworks Solutions, the BU16501KS2-E2 by ROHM Semiconductor and the TPS61050YZGT by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the WS2801S?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
