I want to know is the polarized capacitor has the advantage that they are used in some circuits?
For example, in a schematic of the BISS001 PIR controller IC, in some places, a polarized capacitor is used and in some places a non-polarized capacitor one.
Can I use a non-polarized capacitor with the same voltage and capacitance instead of these polarizing capacitors?

The very thin oxide layers, providing insulation for a certain polarity, provides a very compact energy storage module. Just view those useful electrolytic capacitors as early versions of self-assembled-nano-tech; the manufacturing process creates the very thin oxide layer: the oxide is GROWN or FORMED.

The physical size of a capacitor is a function of the thickness of the dielectric (among other things).
Early on, it was discovered that the oxides of certain metals (aluminum and tantalum in particular) made good dielectrics, and could be made very thin through a chemical process — orders of magnitude thinner than other dielectrics such as waxed/oiled paper and plastic film. Therefore, the electrolytic capacitor was invented to provide high capacitance in a reasonable volume.
Unfortunately, the chemical process requires that the voltage across the capacitor must have only a single polarity, so these capacitors are "polarized". Reversing the polarity degrades and eventually destroys the oxide layer. It's something we just have to live with in order to take advantage of this technology.
