I am no expert, but if the shifter has the same number of clicks and is the same brand, it probably works. Best to ask at the bike shop, but I just crosss my fingers and buy something on amazon.
I used the Shimano Acera ML-310 7 speed unit to replace older Shimano combo units and also an old trigger shifter. I think it clicks up and down nice. Around $17.
