Overview
The Z0103MN is a thyristors (SCR), Module made by onsemi in a SOT-223 package with 4 pins. -40℃~+125℃@(Tj) 1.3V 10mA 1A 3mA 600V 8A@60Hz SOT-223 Thyristors (SCR)/Modules ROHS.
PCBKit's library has its KiCad symbol (Triac_Thyristor:Z0103MN, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-223, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C3614850). 6 open-source boards in 4 repositories on GitHub use it.

Is there a KiCad symbol and footprint for the Z0103MN?
Yes. The symbol is Triac_Thyristor:Z0103MN and the footprint Package_TO_SOT_SMD:SOT-223, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the Z0103MN?
SOT-223, with 4 pins. Its footprint is drawn on this page.
Where is the Z0103MN datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the Z0103MN?
JLCPCB lists it as part C3614850, with 0 in stock; the sellers' links on this page open their listings.
What can replace the Z0103MN?
Parts like it in the library: the BT134W by YFW, the X0202MN 5BA4 by STMicroelectronics, the Z0103MN5AA4 by STMicroelectronics and the BT131S by FUXINSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the Z0103MN?
6 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
