Ah okay, the temperature coefficient should be okay with the MCT0603MC1000FP500 because it is lower. The rest of the caps and resistors all meet the criteria so that should be good too!
As far as the diode goes the one that I chose as a substitute (SD05T1G) has a 0.55 higher breakdown voltage compared to the one listed on the BOM (SD05-7). Does this voltage value need to be the same? Is it okay if it is that much higher?
