Can CBB60 capacitors replace CBB65 capacitors?

From the function of the two capacitors, CBB60 cannot replace CBB65.

CBB capacitor is a general term for a series of capacitors. Although CBB60 and CBB65 are both CBB capacitors, they are different in concept and function.

1、CBB60 Capacitor

CBB60 is a polypropylene film capacitor, the shape is a rectangular (flat) plastic shell, the terminal is a lead wire or a metal insert.

This kind of capacitor is suitable for the starting and running of "one-way motor" powered by 50/60hZ AC power supply, and has the advantages of small size, light weight, low price, low loss and good self-healing effect.

It is generally used in AC motors of household appliances such as washing machines to maintain the operation of the motor.

2、CBB65 Capacitor

The shape package of CBB65 is aluminum shell, round or oval.

This kind of capacitor is suitable for 50/60hZ AC power supply, is an important accessory component of "compressor in air conditioner", and an essential key component for the startup and operation of compressor.

Replace the main parts, preferably the same as the original model. If you can't buy it, you need to replace the capacitor. It depends on the main parameters. In addition to capacitance and rated working voltage, it also depends on insulation resistance, dielectric loss, and manufacturing accuracy (allowable error).

3、Functional Scope

CBB60 and CBB65, both of which are metallized polypropylene film capacitors, are used in circuits powered by 50/60hz AC power supply. They are usually used as starting and running capacitors for motors. They can resist the impact of high voltage and current, and have a good self-healing effect.

CBB60 capacitors have good waterproof and moisture-proof performance, and are commonly used in washing machines and water pumps.

CBB65 capacitors have good high temperature resistance and explosion-proof properties, and are often used in air conditioners and refrigerators.

In an emergency, when CBB60 is used instead of CBN65, the motor can be guaranteed to work, because the two have the same medium and no polarity, and belong to the same type of capacitor.

However, the dimensions of the two are not necessarily the same. At the same time, it is required that the capacity of the replaced capacitor should be consistent, and the withstand voltage must be ≥ the withstand voltage of the original capacitor.

CBB60 and CBB65 capacitors are different types of capacitors, designed and produced for different working environments, with different production processes and packaging forms, and different places of use.

Therefore, the CBB60 capacitor cannot be used as a substitute for the CBB65 capacitor, but if the CBB65 capacitor cannot be found, you can use the CBB60 capacitor for emergency use. After the CBB65 capacitor is found, immediately replace the original type of capacitor.

The difference between CBB60 and CBB65 capacitors

1. Different uses

CBB60 is suitable for the starting and running of one-way motors with a frequency of 50HZ (60HZ) AC power supply.

CBB65 starting capacitors are widely used in the starting and running of single-phase motors powered by AC power with a frequency of 50Hz/60Hz, such as household air conditioners, and power factor compensation for high-power lighting fixtures.

2. Different characteristics

CBB60 type metallized polypropylene film capacitor for AC motor has the characteristics of small size, light weight, low price, low loss and good self-healing effect.

CBB65 cylindrical metal aluminum shell, small size, light weight, excellent electrical performance, low loss, good self-healing characteristics, internal pressure explosion-proof device, safe and reliable use.
