Capacitor code

[Richard309]

Iskra capacitor KNB1560 has this code 40/110/56/B to replace this I can only find one with code 40/110/56/C can anyone tell me the difference?

Welcome to EP.

Can't say for sure but it has to do with the version of "Climatic category IEC 60068-1 standard".
Probably a more up to date version.

40/110 is -40 to +110 degrees Celsius.

Are you repairing broken equipment of some kind?

 

[Richard309]

Yes it's inside my Drayton radio controlled thermostat which is sometimes failing to energise the relay coil, I'm concerned this slight code difference will have an impact

I think it will be fine,go ahead and try it.
This cap is an EMI filter on the line input ,shouldn't be a problem.
