The two capacitors can be interchangeable for some less demanding occasions. And for the rigorous situation naturally can not be replaced at will, after all, for no capacitor, its characteristics and performance is different. The monolithic capacitance is relatively stable, the coefficient of temperature drift is small, the capacitance value can achieve 1 UF, the life is long, the equivalent DC resistance is small, the price is slightly expensive. The high frequency characteristic of the ceramic chip capacitance is good, but the capacitance value can only be 0.1uF.
The two different capacitors, the monolithic capacitor and the ceramic chip capacitance, have the same characteristics, that is, there is no difference between positive and negative electrodes. Only electrolytic capacitors are positive and negative. For monolithic capacitance, its disadvantage is that the temperature coefficient is very high, the stability and drift of the oscillator is unbearable, and if it is replaced by polyester capacitance will be a lot better.
