The questions:

1. What should I look for when searching for a PCB relay to drive inductive loads?
   
2. Do you know any small PCB relay (ideally under 22x5 mm) that is good for that? (ex. G3MB (datasheet) seems to be a good option, but it's discontinued)
3. Any tips on how I could find relays like that (digikey, etc do not allow you to filter by snubber, peak-switching, etc)

The context:
I am driving DIN mounted latching relays with a custom build PCB. I usually switch on and off the PCB relays very quickly, around 100ms.

So far, I have been using PCN105D (datasheet)

The problem I have is that this relays creates very large spikes, that I tried to fix with capacitors and diodes on top of the relay driver (ULN2003A datasheet) but nothing seems to work. (link to another question describing the issue)

I have tried replacing the relay with an SSR and that seems to fix my problems. Reading as much as I could find, To drive inductive loads from my PCB, I need a peak-switching SSR relay with an internal RI Snubber.

The problem I have is that I could not find small&slim (under 25x5mm) PCB relay with internal snubber, and even less with peak-switching.
