What are the new MHS series part numbers that replace the non ROHS conform cadmium plated parts?

For the receptacle, we recommend to switch to RoHS conform parts:

There exists also a very old part number of the receptacle which is part 50E3-1.  which used to be cadmium plated.  50E3-1S is now replaced by MHSRF33S if you need stainless or MHSRF33Z for zinc plating (replacemnt of 50E3-1)
For the studs, please note that the belleville washers are cadmium plated, this means the full part is toxic and not RoHS conform, please switch over to the new version.

Note that the working temperature of cadmium plated parts is higher than of zinc plated parts.

The reason for this is that the cadmium plated parts are manufactured according to an aerospace standard.
