Questions

Is there a KiCad symbol and footprint for the SHT41-AD1F-R2?

Yes. The symbol is Sensor_Humidity:SHT4x and the footprint Sensor_Humidity:Sensirion_DFN-4_1.5x1.5mm_P0.8mm_SHT4x_NoCentralPad, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the SHT41-AD1F-R2?

DFN-4(1.5x1.5), with 4 pins. Its footprint is drawn on this page.

Where is the SHT41-AD1F-R2 datasheet?

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

Where can I order the SHT41-AD1F-R2?

JLCPCB lists it as part C7461862, with 3,558 in stock; the sellers' links on this page open their listings.

What can replace the SHT41-AD1F-R2?
