Franjobaim relay old/new type not documented

------Question for FR-AS12-BM-2 Please Put your question below------

I have a 24VDC 35 Amp switching requirment. I would like to use screw terminals with 12V control. The part avaialble (in stock) listed above meets the requirment. However, when looking at the attached datasheet from Franjobaim they list the FR-AS12F-BM 1Z in there catalog. While all of the specifications are the same the difference is the additional F in the part number. In addition there is a note that says “We suggest new type should be selected”. I am assuming that the F is the addition for new type. Does this mean the digikey stocked part is the old type and not the new type suggested?
