Overview
The RTC5639E is a RFID IC made by RichWave in a QFN-16-EP(3x3) package with 17 pins. QFN-16-EP(3x3) RFID ICs ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:RTC5639E, from EasyEDA) and its footprint (EasyEDA_Cloud:QFN-16_L3.0-W3.0-P0.50-BL-EP1.7, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C474877).

Questions
Is there a KiCad symbol and footprint for the RTC5639E?
Yes. The symbol is EasyEDA_Cloud:RTC5639E and the footprint EasyEDA_Cloud:QFN-16_L3.0-W3.0-P0.50-BL-EP1.7, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the RTC5639E?
QFN-16-EP(3x3), with 17 pins. Its footprint is drawn on this page.
Where can I order the RTC5639E?
JLCPCB lists it as part C474877, with 0 in stock; the sellers' links on this page open their listings.
What can replace the RTC5639E?
Parts like it in the library: the CI522 by Nanjing Zhongke Microelectronics, the RTC7625HE by RichWave, the FSV9510C by Forsinve and the RF430CL331HIRGT by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
