Is there a KiCad symbol and footprint for the WS1850T?
Yes. The symbol is EasyEDA_Cloud:WS1850T and the footprint EasyEDA_Cloud:QFN-32_L5.0-W5.0-P0.50-TL-EP3.1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the WS1850T?
QFN-32, with 33 pins. Its footprint is drawn on this page.
Where is the WS1850T datasheet?
wisesun publishes it: the Datasheet link on this page opens it.
Where can I order the WS1850T?
JLCPCB lists it as part C7427513, with 3,817 in stock; the sellers' links on this page open their listings.
What can replace the WS1850T?
Parts like it in the library: the MFRC522 by JSMSEMI, the JSM66302 by JSMSEMI, the ST25DV04KC-IE6S3 by STMicroelectronics and the CLRC66303HNY by NXP Semiconductors. Check their datasheets: a part that fits the footprint may still differ in its ratings.
