Most of the time manufactures will have a "mating connectors" section in the description (and sometimes you can find that info on digikey as well). For your case, the only mating connector (by TE) seems to be the 284506-4, which is not mounted on a PCB...
I would compare the drawings of TE's 284506-4 and the one you found by Phoenix Contact. They have some differences, just make sure that they will be compatible.
