Is there any difference between the old and new series C 9050JCK timing relay`s start up parameters?

Yes. The published reset or start up time for both units is 100 mseconds. In reality the old units had a reset or start up time of 60 mseconds and on the new units it is 75 mseconds. This will cause problems in circuits that have the power up or initiating circuit racing with the timer. There have been circuits that would work with the old timer that will not work with the new timer. The customer will have to redesign the circuit to remove the device racing with the timer.
