It is necessary to ensure that the current gain of the replacement transistor dqtasheet about the same as the original. The replacement should have the same application if possible.

Welcome to our store Customer Traneistor electronic products manufacturers, different batches and other reasons, there may be purchased with Picture is different, please contact us before you buy, to help us provide you accurate service Please feel free to contact us! To be on the safe side, ensure the maximum operating voltage of the replacement transistor is at least twice the rail voltage of the circuit in which it is operating Current gain: The circuit will be designed around a particular voltage drop.

High power transistors often offer lower gains – older power transistor types may be as low as 20 – 50, whereas the smaller transistors may offer gains anywhere between 50 and In this way it is usually possible to find a suitable replacement transistor.

This should be about 0. Transistors are normally given an indication of their application in the datasheets. Choosing a replacement tranwistor with approximately the same current gain is necessary. Every time you open a dispute, our shop may be closed, so when you receive the product model does not match or the product does not work, or send the number is not datashet, please do not open the dispute, contact our customer service is the best Solution.


Most transistors will either be germanium or silicon. If this is the case, it is necessary to re-visit the way in which the choice of the replacement transistor was made and see if any mistakes were made or look for other datasheeg that may affect the operation of the transistor circuit.

Choose a transistor with a similar power dissipation: It is best to be more cautious with these packages. Select a replacement transistor with equivalent Ft: Automatic mini egg incubator for hatching chicken egg parrot goose duck Quail transisror for sale. Although most of the main points have been covered in the points above, it is always best to be on the look out for other parameters that may affect the choice of transistor replacement.

Careful examination of the application will enable this to be verified. Choosing a replacement transistor with the same package and pin-out will mean that many of the characteristics including power capability are the same. Then take this and choose a replacement transistor gransistor can easily operate at this frequency. Shop from the world’s largest selection and best deals for ASUS 3.

Don’t go for a transistor with a much higher Ft as this may increase the risk of oscillation.

These instructions are set out in an approximate order of the most significant parameters first followed by the less significant ones:. These will include the basic parameters of the transistor operation performance.

In most cases it will operate satisfactorily, but occasionally there may be a problem. Those packages designed for mounting on heatsinks will be more variable because they can often dissipate more power dependent upon the heatsink.


For germanium it is around 0. Other devices may also appear in what may appear to be transistor packages at first sight. Sometimes it is very easy to find out the parameters of a particular transistor as it may be possible to find them on the Internet or in a transistor data book.

It is necessary to ensure that the replacement transistor will be able to operate at the relevant frequencies, so a similar or slightly higher Ft is advisable. Once the transistor specifications and parameters have been ascertained, it is possible to check for other replacement transistor types with similar parameters that will be able to operate within the circuit in question.

This is often defined by the package in which the transistor is placed. It is important to find out whether the transistor is silicon or germanium. Your satisfaction is our goal! It is necessary to vatasheet that the replacement transistor can handle the power that it will dissipate within the circuit. Often a lower current gain may be acceptable. For example a low trznsistor general-purpose transistor is unlikely to work well in a switching application even if it has a high ft or frequency limit.

The current gain of transistors is notoriously difficult to specify. Other types are normally only used in very specialist applications. It may be possible to discover this in a number transixtor ways. Fast ship to EU!
