Questions
Is there a KiCad symbol and footprint for the REF191FS?
Yes. The symbol is Reference_Voltage:REF191 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 REF191FS?
SOIC-8, with 8 pins. Its footprint is drawn on this page.
Where is the REF191FS datasheet?
Analog Devices publishes it: the Datasheet link on this page opens it.
Where can I order the REF191FS?
JLCPCB lists it as part C3680504, with 0 in stock; the sellers' links on this page open their listings.
What can replace the REF191FS?
Parts like it in the library: the ADR430ARZ by Analog Devices, the REF191GSZ-REEL by Analog Devices, the ADR430ARZ-REEL7 by Analog Devices and the ADR430BRZ by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
