Overview
The ADR421ARM is a voltage Reference made by Analog Devices in a MSOP-8 package with 8 pins. -40℃~+125℃ 1.75uVp-p 10mA 10ppm/℃ 2.5V 4.5V~18V 500uA Fixed Temperature compensation control ±0.12% MSOP-8 Voltage Reference ROHS.
PCBKit's library has its KiCad symbol (Regulators:ADR42x, from CERN's library) and its footprint (Package_SO:MSOP-8_3x3mm_P0.65mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3679985).

Questions
Is there a KiCad symbol and footprint for the ADR421ARM?
Yes. The symbol is Regulators:ADR42x and the footprint Package_SO:MSOP-8_3x3mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ADR421ARM?
MSOP-8, with 8 pins. Its footprint is drawn on this page.
Where is the ADR421ARM datasheet?
Analog Devices publishes it: the Datasheet link on this page opens it.
Where can I order the ADR421ARM?
JLCPCB lists it as part C3679985, with 0 in stock; the sellers' links on this page open their listings.
What can replace the ADR421ARM?
Parts like it in the library: the ADR421ARMZ-REEL7 by Analog Devices, the ADR441ARMZ-REEL7 by Analog Devices, the LT6657AHMS8-2.5#TRPBF by Analog Devices and the MAX6126B25+ by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
