The only thing I can think of is that it would be smaller than two separate capacitors, so space-saving, but then it supposes that you need the two (identical?) values at the same place on the PCB, and a common pin.
Yes, you can replace AC capacitors with different ratings. But you''ll have to consider the 20% tolerance range. For example, a 35/5 capacitor can''t be replaced with a 45/5 capacitor. It''s because the maximum tolerance for a 35/5 capacitor is 42 uF. You should also prioritize picking a higher value.

This video explains the difference between single run and dual run capacitors.
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
The Dual Run Capacitor is a great advantage to motors, as it stores electrical energy and releases it when required. This ensures that the motor starts quickly and runs smoothly! A dual-run capacitor allows the system to operate more efficiently and use less energy by simultaneously providing power to both motors.
What Does the VAC on a Capacitor Mean? The VAC rating of a capacitor is the maximum alternating current voltage that the capacitor can safely handle. It is the second most important rating of a capacitor, the capacitance rating being the first. It is extremely important to use the proper VAC-rated capacitor, otherwise, accidents may happen.
2)soaking-out capacitor, the reading will high its value 3) open-circuit capacitor, will displayed "0". (maybe ±10pF at the 200pF range) 4) Display value will fluctuated, if a soaking-out capacitor connected. What does it mean by soaking-out capacitor?
Take note that a capacitor''s voltage rating is not the voltage that the capacitor will charge up to, but only the maximum amount of voltage that a capacitor should be exposed to and can store safely. For the capacitor to charge up to the desired voltage, the circuit designer must design the circuit specificially for the capacitor to charge up ...
If one of these capacitors fails, your technician may decide to replace both parts with a dual capacitor. A dual capacitor is like getting a combo pack of candy bars. The device performs the same job as both the start capacitor and run capacitor. It gives your unit that important initial spark and supplies a consistent flow of electricity to ...
In contrast to fixed resistors that maintain a constant resistance value, potentiometers act as variable resistors. These devices operate as voltage dividers, serving a dual purpose of adjusting voltage output within a circuit and accurately measuring electric potential, hence their designation as potentiometers.
The goal is to optimize the efficiency, performance, and torque of the motor. You can find a motor capacitor in an air-conditioning unit, spa pump, large fans, powered gates, etc. What are MFD Capacitors.

In plain English, this capacitor can be used at voltages up to 370 Volts Alternating Current. Use of this capacitor at lower voltages than 370 VAC is acceptable (so you can use it on a motor powered at 120 VAC Volts-Alternating Current or at 240 VAC). Duty Frequency Range: 50/60 Hz. The capacitor can be used at a frequency range of 50-60 HZ.
The amount of electrical energy stored in the capacitor is known as its capacitance. The Capacitance of a capacitor is directly proportional to the capacity of the capacitor for storing charge. For example; the bigger the tank the more water it can store similarly the bigger the capacitance, the more charge it can store. How to Increase Capacitance
