Replacing Capacitors: Which Values to Follow and Which Ones

Hi, in general, when replacing capacitors, which values (be it capacitance, voltage, ripple current, leak current, ESR, e.t.c.) must be followed and which ones are ok to be different? This mostly depends on the particular circuit. However, if the part will fit physically, a higher voltage rating will be ok. and lower leakage is ok.

The replacement capacitors may not be available in exactly the same capacitance values as the original components. This is not normally a problem, simply fit the closest available. For example, a new 0.047uF component could be used to replace a faulty 0.04uF or 0.05uF capacitor. The original capacitors (in particular wax-paper types) may have a ring marked on one end. The

Replacing Electrolytic Capacitors In Vintage Electronic Gear

A can capacitor from CE Manufacturing with four sections (40/20/20/20) can cost $40.90. A similar JJ can capacitor costs $16.95. After researching options for my many projects, I got tired of paying $15-50 to replace every can cap. And if a project had more than one of them, it got very expensive. One old piece of test gear I rebuilt had four of them! The new caps cost more than

8.2: Capacitors and Capacitance

The capacitance (C) of a capacitor is defined as the ratio of the maximum charge (Q) that can be stored in a capacitor to the applied voltage (V) across its plates. In other words, capacitance is the largest amount of charge per volt that can be stored on the device:

Capacitor Characteristics

Capacitors are rated according to how near to their actual values they are compared to the rated nominal capacitance with coloured bands or letters used to indicated their actual tolerance. The most common tolerance variation for capacitors is 5% or 10% but some plastic capacitors are rated as low as ±1%.

6 FAQs about [Capacitor replacement ratio]

Is it necessary to replace a capacitor with an exact replacement?

No, it is not necessary to replace a capacitor with an exact replacement. In many cases, replacing a capacitor with a higher or lower value can make the circuit perform differently or better than before. However, keep in mind that increasing the capacitance may affect the resonant frequency of LC circuits and also increase their current draw.

Which values should be followed when replacing capacitors?

Should you replace a capacitor with a higher capacitance rating?

Generally speaking, you should always replace like-for-like when it comes to capacitors – meaning if your capacitor has a capacitance rating of 10μF, you should select a new one with the same value. However, there are times where it may be necessary to replace with a higher or lower capacitance rating.

How much does a capacitor replacement cost?

On average, the cost of capacitor replacement typically ranges from $100 to $300, including both the cost of the capacitor itself and the labor for installation. However, this is a general estimate, and actual costs may vary based on individual circumstances. Additional factors that can influence the cost of capacitor replacement include:

How do I replace a capacitor?

Replacing a capacitor is a straightforward process when approached methodically. Here’s a step-by-step guide to help you navigate through the replacement procedure: Prepare Your Workspace: Select a clean, well-lit area with ample space to work comfortably. Ensure proper ventilation and access to necessary tools and materials.

Can I replace a 30/5 capacitor with a 35/5 capacitor?

Yes, you can generally replace a 30/5 capacitor with a 35/5 capacitor. The first number (30 or 35) represents the microfarad (µF) rating for the compressor, while the second number (5) represents the µF rating for the fan motor. A slightly higher capacitance value for the compressor won’t significantly impact the performance of your AC unit.
