I take it that has an appliance spigot attached to it and you have a new sink too and it won't fit onto the old waste pipe run? That'll why it's too low now, deeper sink so you can't use that trap with the appliance coupler on it. You need to use the one that @Terrywookfit has linked to and then add in an appliance spigot somewhere else. Either that or if the pipe's through the back then take the sink unit out and alter the waste pipe.
