can i use this relay for 220vAC?

It states maximum switching voltage as 220vdc so you should be OK for AC.
Also the current capacity rating will depend on whether it is resistive or inductive load.

Since this relay is sold as a "signal" relay, and is specified only for DC operation, I would worry about using it to break a circuit that could apply 220*1.414 = 311Vpeak across the opening contacts...

The DC rating is usually the most critical out of the two, AC-DC.
Also when you break a DC inductive load a voltage much higher than the applied V is inclined to appear.

I checked the signal relays I have here and they are rated at 1.5Kvac at the contacts.
The one the OP shows lists 2Kvac insulation between contacts and coil.
