If possible get the exact replacement to avoid 'call back' from your customer. When i substitute another transistor with the spec about the same as the original, the monitor work perfectly fine and when i use my finger to touch it, the transistor only got a little bit warmed which is normal. I have tested a transistor with the storage and fall time slightly out from the original specification and when i switch on the monitor it only worked for few hours before it became real hot and can burn your finger. Different transistor have different spec, if you really want to find a replacement for horizontal output transistor make sure you look at the storage and fall time as well besides bigger voltage, current and wattage. The real problem is in the switching time which we call it the storage and fall time. ![]() Why the transistor blow even if it has a higher voltage, current and watt compare to the original transistor?. Higher voltage, ampere and wattage will cause complete destruction to the transistor because it is not easy to find an exact replacement for horizontal output transistor. If you are looking for replacement of signal transistor, a higher voltage, amp,and watt will do the job but not in the case if you want to find a replacement for horizontal output transistor. There is one tip for you if you want to find a replacement for a transistor. The normal transistor subtitution book only show you the voltage (v), current (amp) and wattage (w) rating but the ECG master replacement guide show beyond than that such as the frequency, current gain and the diagram of that particular transistor that you are searching for. Though you can find a replacement from the smaller version of the transistor databook, the ECG master replacement guide provide better information and more reliable specification compare to the normal transistor substitution replacement book. In this guide it will list out all sort of transistor data and specification which include the bipolar transistor, field effect transistor (fet), junction field effect transistor (jfet), signal transistors, high voltage transistor such as the horizontal output transistor, silicon power transistor, surface mount transistor, digital transistor and many more! Shipping: Flat Shipping, Registered Air Mail, DHL/EMS/FEDEX starting at. Minimum order quantity starting at ONE piece, you can buy as many as you want. Not only that, the equipment also can't be repair due to unable to find the exact replacement. 2SA1617 SOT-23: Manufacturer Part Number(MPN): 2SA1617: Availability: In Stock Can ship immediately: Price starting at US 3.00 / piece, All prices are unit prices in United States Dollars (USD). ![]() Without this guide i will be searching in the dark and waste my precious time. The cost of this book is not expensive and if you are in the electronic repairing line, i highly recommend it. You can see the internal diagram of that particular components, pin out, voltage, replacement, block diagram and the component's layout. In the content you can find out all sort of the components specification. The most popular transistor cross reference replacement guide is the Philip ECG semiconductor master replacement guide. Transistor cross reference replacement and guide is very important for every engineers and technicians because the data that you found in this guide can help you to find the exact replacement for the components that you are looking for such as transistor, fet, ic, diode, zener diode and etc. I cant remember the exact adrress off hand.The one problem you may run into, if you are working on early transistor stuff, many of the old numbers have been deleted from the cross ref guide to make room for newer #'s so if you are working on a lot of older stuff it may be helpfull to get a few older manuals.Sam's published a few manuals in the 60's I have a few, I'd have to dig for them for titles if you like.Also many of the early 70's sylvania tube manuals had Sylvania ECG cross ref's in the back - same thing with rca.ECG and NTE part numbers are the same.Even if you find ECG part #'s in the old 70's books they are very likely still available.Electronic Components> Transistor>transistor cross reference replacement Transistor Cross Reference Replacement ![]() SK also publises a cross ref book that is free and very helpful.Nte also has a website with an online cross ref. this has always worked out well unless the circuit it's used in is very critical. I sort all of my surplus transistors and label them with NTE numbers for quick replacements. The specs for the new replacement will generally not be identical to the original, but they will be very close. The nice thing about the book version, is you can find your specific replacement and look up the specs in the book for it. NTE even has free cross ref software thats usefull if you're in a hurry. NTE cross books are usally available for free at places that sell NTE. Norm is correct except for the fact that EGG is no longer in buisiness, they have been absorbed by NTE.
