Overview
The CD4021BCM is a shift Register made by onsemi in a SOIC-16 package with 16 pins. -55℃~+125℃ 16MHz 3.4mA 3.4mA 3V~18V 4000B 500mW 70ns@15V,50pF 8 Asynchronous parallel load function Parallel or Serial to Serial SOIC-16 Shift Registers ROHS.
PCBKit's library has its KiCad symbol (4xxx:4021, from KiCad's library) and its footprint (Package_SO:SO-16_3.9x9.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3304323).

Questions
Is there a KiCad symbol and footprint for the CD4021BCM?
Yes. The symbol is 4xxx:4021 and the footprint Package_SO:SO-16_3.9x9.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CD4021BCM?
SOIC-16, with 16 pins. Its footprint is drawn on this page.
Where is the CD4021BCM datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the CD4021BCM?
JLCPCB lists it as part C3304323, with 0 in stock; the sellers' links on this page open their listings.
What can replace the CD4021BCM?
Parts like it in the library: the CD4014BCM by onsemi, the CD4021BCMX by onsemi, the CD4035BM96 by Texas Instruments and the CD4021BCN by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
