I wouldn't bet on it, but try it... see if it works for you. If they're anything like the 2010 minis, then they are going to be real fickle about an exact match.
They are far far far better with ram then 2010 mac mini's

As the title says, will 1600MHz RAM clock down in the Mini?
If you have the ram please try it I THINK IT WILL WORK.
I did 20 plus 2011 mini's with crucial, corsair, pny, patriot, gskill, hynix, samsung 4gb sticks and a few with elpida 8gb sticks corsair 8gb sticks and samsung 8gb sticks.
Also the 2011 have come with 1gb and 2gb hynix and samsung sticks. They have all been good.
The 2010 minis were really choosy with 4 gb ram sticks basically samsung were gold and lots more were hit or miss. I stopped upgrading the 2010 minis because of this.
No 2010 mini ever downclocked ram perfectly for me. I have 2 2010's on hand now and have to wait for more samsung sticks. A pita
