Questions

Is there a KiCad symbol and footprint for the HTU21D?

Yes. The symbol is EasyEDA_Cloud:HTU21D and the footprint EasyEDA_Cloud:DFN-6_L3.0-W3.0-P1.00-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the HTU21D?

DFN-6-EP(3x3), with 7 pins. Its footprint is drawn on this page.

Where is the HTU21D datasheet?

TE Connectivity publishes it: the Datasheet link on this page opens it.

Where can I order the HTU21D?

JLCPCB lists it as part C83479, with 3,073 in stock; the sellers' links on this page open their listings.

What can replace the HTU21D?

Parts like it in the library: the SI7006-A20-IM1R by Silicon Labs, the SI7006-A10-IM by Silicon Labs, the SI7006-A10-IM1 by Silicon Labs and the SI7006-A20-IM by Silicon Labs. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the HTU21D?

23 boards in 17 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
