Is there a KiCad symbol and footprint for the BL3021?
Yes. The symbol is EasyEDA_Cloud:HL3053 and the footprint EasyEDA_Cloud:DIP-6_L7.3-W6.5-P2.54-LS7.6-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BL3021?
DIP-6L, with 6 pins. Its footprint is drawn on this page.
Where is the BL3021 datasheet?
Galaxy Microelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the BL3021?
JLCPCB lists it as part C41425722, with 0 in stock; the sellers' links on this page open their listings.
What can replace the BL3021?
Parts like it in the library: the BL3063 by Galaxy Microelectronics, the BL3073 by Galaxy Microelectronics and the CNY17-4 by Vishay Intertechnology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
