I've taken the sword out of my car and I'm about to buy the MOSFET transistors to replace the old ones but I can only find 14A 50V ones. All the repair procedures i've read say to replace them with 16A 60V transistors. Is it crucial to use the correct type or will the lower rated ones work? As i'm in Australia, the cost of getting the parts shipped from mouser.com is about 5 times the price of the parts where as I can get the 14A's down the road for a couple of bucks! What should i do? .
