680 uF is a special order and takes weeks to get. I have found some suscon 820 uF 6.3V that fit (8x12 mm). Does anyone know if the increased capacitance value will be a problem If the value is larger but the package size is the same.
We are also having problems with 411 boards. 4 failed in the last 2 weeks. 3 bulging Suscon SJ Capacitors on the board when it happens. Green in color with Gold markings. Arrgh, I just installed 45 of these boards... all require bucket truck rolls.
