I have made a daynight switch for my LED solar lights and have been switching a relay through a BC547 transistor.
I have included a time delay by doing the following
From the output (pin 6) through a 30K resistor a 470μF capacitor is charged. A 100K resistor feeds the base of a BC547 which turns on a 12 Volt relay.
For the sake of Space I want to take out the 12Volt relay and substitute it for a TIP41.
My question is will i be able to substitute the BC547 with the TIP41 ( Naturally observing the pin spacings are not the same) Or will I have to have the BC547 to turn on the TIP41.
Many thanks in advance for the help.
