Questions

Is there a KiCad symbol and footprint for the ST1S41PHR?

Yes. The symbol is EasyEDA_Cloud:ST1S41PHR and the footprint EasyEDA_Cloud:ESOP-8_L4.9-W3.9-P1.27-LS6.0-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ST1S41PHR?

SOIC-8, with 9 pins. Its footprint is drawn on this page.

Where is the ST1S41PHR datasheet?

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

Where can I order the ST1S41PHR?

JLCPCB lists it as part C2070789, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ST1S41PHR?

Parts like it in the library: the SCT9336STER by SCT, the PAM2423AECADJR by Diodes Incorporated, the BD90640EFJ-CE2 by ROHM Semiconductor and the SCT2452STER by SCT. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the ST1S41PHR?

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