Hello…
I think you didn’t search for new parts on google or here…
Also, you can’t always find every unique part, by their part number/name…

You have to search on fritzing as triac, scr, optocoupler etc…

You can use MOC3021, and change the “Part #” as MOC3031, their pinout is same…

And, for Triac (BT136, BT134, BT139), there is a TO-92 available, but pinout is different,

Here, I made a TO-220 Triac , you can set “Part #” as your requirement…
