I want to make a HeaterMeter, but there are no kits available right now, so I'm trying to acquire all the components on my own. I wasn't able to find all the parts because they were either out of stock or require buying minimum 200 pieces. So I tried finding substitutes for those parts and I need help to make sure they will work.
I made a BOM on Octopart with all the parts and substitutes written in the description. I believe almost everything will be a direct substitute except for the 16 Mhz resonator, ZTT-16.00MX, which I substituted with a 490-6001-1-ND. The original has a 30 ohms impedance, while the substitute has a 50 ohms impedance. I don't know much about this stuff. Will that be a problem?
