Overview
The BCW255A is a solid State Relay made by BC in a SMD-8P package with 8 pins.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:BCW251A, from EasyEDA) and its footprint (EasyEDA_Cloud:SMD-8_L9.7-W6.4-P2.54-LS9.7-BL, from EasyEDA), ready for a KiCad board. 100 are in stock at JLCPCB (part C48533648).

Is there a KiCad symbol and footprint for the BCW255A?
Yes. The symbol is EasyEDA_Cloud:BCW251A and the footprint EasyEDA_Cloud:SMD-8_L9.7-W6.4-P2.54-LS9.7-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BCW255A?
SMD-8P, with 8 pins. Its footprint is drawn on this page.
Where is the BCW255A datasheet?
BC publishes it: the Datasheet link on this page opens it.
Where can I order the BCW255A?
JLCPCB lists it as part C48533648, with 100 in stock; the sellers' links on this page open their listings.
What can replace the BCW255A?
Parts like it in the library: the LBB110STR by Littelfuse/IXYS, the LAA108STR by Littelfuse/IXYS, the LBA127LSTR by Littelfuse/IXYS and the LBB127STR by Littelfuse/IXYS. Check their datasheets: a part that fits the footprint may still differ in its ratings.
