The friction lock fastening keeps the header mated to its receptacle under moderate vibration — the kind you get from a nearby motor or a panel door being closed repeatedly. It's not a full latch, but it's enough to stop the connector from backing out on its own.
Yes, the 1744048-4 is ROHS3 Compliant. No exemption issues — it's a straight RoHS3 part.
Derate above 25 °C ambient per the standard curve in the product drawing — the -25 to 105 °C operating range gives you headroom for most indoor applications.
