Sometimes the demands of the application such as power dissipation,
“on” resistance, voltage, temperature coefficient, etc. limit the selection
of the photocell to one particular device. However, more common is the
case where any number of photocell types can be used, especially if
minor changes are undertaken at an early enough point in the circuit
design. In these cases, price is often the deciding factor.
