Is there a KiCad symbol and footprint for the DA112S1RL?
Yes. The symbol is EasyEDA_Cloud:DA112S1RL and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the DA112S1RL?
SO-8, with 8 pins. Its footprint is drawn on this page.
Where is the DA112S1RL datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the DA112S1RL?
JLCPCB lists it as part C435883, with 0 in stock; the sellers' links on this page open their listings.
What can replace the DA112S1RL?
Parts like it in the library: the SMDA12C.TBT by SEMTECH, the LCDA12 by SMC, the SMDA12-6/TR7 by Microchip Technology and the SMDA12-6E3/TR13 by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
