Where have all the G8P Omron Relays gone?
Omron obsoleted the G8P relay series back in 2016 and since then people have been trying to find suitable replacements. Omron did not leave their customers without options in most cases. As you can see in the screen shot below, they have provided us a list of recommended replacements.

While these are electronically suitable, they are NOT foot print equivalents!
The G8P relay series use this foot print.
In comparison, these are the footprint arrangements on the other two relay series. For people who are designing new circuits this most likely would not be a problem but for those looking to place them in existing circuits will find this troublesome.
Don’t Panic, There is still hope!
Here are a few series of relay that do match the footprint of the original G8P
