I simply thought this type of relay would fit in my PCB but it doesnt.

What should I look for to make them fit together? are there any standards?

You need to look for a relay that conforms to 2.54mm or .2" grid spacing.
Also Vero strip board is nice way to mount prototypes etc.

do aliexpress or other shops write this in their product description or what should I look for?
Even if they do, you can't trust it. Product description summaries are notoriously unreliable, even when dealing with more reputable vendors.

You need to look at dimensions in the datasheet. If there's no datasheet, you're flying blind.

just out of curiosity as it won't solve your square block round hole problem. would it fit if you had 7 row pcb with relay turned to the side? You might need a different board also... are you opposed to using wires and heat shrink to connect relay? The best way of doing this is to make the pcb and pads fit the component...

HK-3FF-DCxx is a DIP based version.
Probabally ebay best source.
Otherwise Digkey is who I use.

my google doesnt find anything on "digkey".

I found HK-3FF-DC on ebay.

I have used that type of relay many times, you have to drill the common leg on the PC board, and the other pins should fit.
I think they will might almost fit.

hi,
Another supplier.

You can also buy ready made PCB boards from Amazon
ready made?
