Also, Mica, unlike any other dielectric has certain interesting "secondary" properties, which contribute (cannot really say more here). So there are applications where silver mica capacitors rule, but they usually involve significant DC Voltage gradients across the capacitor. Without DC you may find Polystyrene and/or teflon better.

Film Capacitor | Capacitor Types | Capacitor Guide
Film capacitors are widely used because of their superior characteristics. This capacitor type is not polarized, which makes them suitable for AC signal and power use. Film capacitors can be made with very high precision capacitance values, and they retain that value longer than other capacitor types.
Standard silver mica capacitors are normally designed to handle voltages from 100 to 1000 volts. High-voltage RF transmitter applications can call for higher tolerances. Mica capacitors are available for voltages up to 20kV. Our expert engineering team can create the mica capacitor with the characteristics you require.

Ceramic Capacitors Uses and How They Compare to Alternatives
What is a Ceramic Capacitor? Ceramic capacitors were first developed in the 1920s in Germany as a substitute for mica dielectrics. In the 21st century, the International Electrotechnical Commission (IEC) currently separates ceramic capacitors into two classes. Per the IEC guidelines:
First, there is a combination film capacitor that takes the temperature coefficient of two different dielectrics to provide a near 0% change between 0°C thru +50°C. Electrocube''s 730D Series capacitor is a metallized capacitor and the size is extremely small in comparison to the original polystyrene film and foil design.
New capacitors will have different preferred values from the old ones. Just chose the nearest one unless it is in a tuned circuit. You should not need to replace ceramics or mica caps.
