Subject: Commercial components vrs industrial
Recently I have been hearing there is no difference between commercial component production lines and industrial component production the only difference is the testing at the end of the line. Is thia true ?if so what risk is it to use a commercial componet for industrial temperatures?

Some microcircuits are specifically designed for extended temperature conditions, other are mearly up-screened through testing. To determine which situation it is, one must contact the part manufacturer. In both of these cases, all electrical parameters for the part should be met across the entire temperature range. The risk of using a commercial part from an industrial/commercial line that is operated beyond the stated temperature range is the problem of poor or no electrical performance at the extremes. If you need good performance or high reliability for extended temperatures, then the temperature designed industrial grade part or the up-screened industrial part is the best approach.
