questions on replacing thermostat for my Samsung dryer

My dryer produces no heat, I tested and determined that one thermostat is dead. The problem now is finding the replacement part. The upside label of the thermostat says "pcc" and "pw-3" The other side of label says "pw-3v 2121 n160" I googled for the part, the only one I can find is "pw-2 N160". I am not sure if the one I found is OK. What does the number 3 in "pw-3" mean? Thanks!
