ECG Transistor Replacements

Quite often when we come across any transistor problems like finding the specification of a transistor we will usually look for transistor data book. It is either from the handy transistor replacement guide book volume 1 and volume 2 or from the Philip ecg master replacement. If you are in the electronic repair industry I suggest that you get these data books as it will help you to save time especially finding an equivalent transistor part number. The ecg master replacement guide have more data or info compare to the handy transistor guide book. You have to remember this though the transistor guide book recommend some other transistor part number as substitution but not all are accurate. Of course you can use the substitution part number suggested as your replacement first, if work then it's ok however if the replacement transistor keep on shorting you might consider to get some in-depth information straight from the manufacturer.
The data provided in the ecg transistor replacements book sometimes is not enough to find a 'good' replacement. Just go to google search engine and type in the transistor part number. If possible key in the whole part number for example if you type in the part number such as the 5S0965 you will not get to the manufacturer instead it list down some electronic suppliers or distributors selling the particular parts. Type in the complete part number KA5S0965 and this will make the google to find the exact info and sometimes straight to the KA5S0965 pdf file where you can download and compare the data. Always remember that use only the original part first so that the equipment will last longer. If you really can't get the original part number then substitution is the only solution.
