if you understand the circuit, test your legs to select a new part and see how it works. 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. If you don't have a clue, try to get the exact replacement part. To properly answer this question involves understanding the circuit design. The obvious parameters to satisfy are breakdown or max collector voltage, next is beta (hfe), finally for more specialized applications noise, or gain bandwidth. Just like you can replace a bolt with a stronger bolt, your can replace a transistor with a stronger (better) part 99% of the time. A low voltage low current GP device, and higher voltage GP parts, and very low noise parts for preamp front ends. Agilent Cross References Allegro Competitive Semiconductor Cross Reference in Alpha-Numerical Order (PDF, 185k) (Updated 07/13/02) This Cross-reference is. I still have hundreds of the 3 legged buggers sitting in my back lab. In circuit design there are (were?) many transistor applications where a design engineer used the GP NPN or PNP device that he already has in stock. The rules for substituting is pretty much the same as the rules for initially selecting transistors, while it's a little like replacing nuts and bolts in a car, you want the replacement to be strong enough and fit in the hole. Is there a general rule for value deviance (I'm thinking hFE and power dissipation: if higher no problem?) or does it exclusively depend on the circuit the transistor is used in?
#TRANSISTOR CROSS REFERENCES HOW TO#
However, even if I had the schematics, I still wouldn't really know how to find close enough substitutes.
#TRANSISTOR CROSS REFERENCES FREE#
I haven't been able to source a free copy of the schematics yet, so not sure exactly what the transistors do, but I thought I might give it a try anyway.

Most of the transistors I'm looking for are designated as "general purpose", used in the (motor) control section of an old CD player (i.e., 2SA933 = 2SA733, 2SA970, BC556 - so probably all fine).īut there are a few I can't find equivalent matches for that look close enough. They use polarity to impede, enhance, or control the flow of electrons, having a PNP or NPN configuration. The transistors function as a gatekeeper for the circuit, letting specific currents flow. A quick search on the net gave me these pages. Enjoy a variety of offers for a wholesale transistor cross reference, bipolar transistor, JFET transistors, and much more. Hi, Ive been working on my new T-582 and found a bad transistor on the vibrato circuit. These products are, in the manufacturer's opinion, similar and can be used for the same purpose.I need to replace a few obsolete transistors. Hammond T-582 Transistor cross reference. Please note the differences in the specs such as, ampere ratings, voltage ratings, and physical color when looking for alternates to these products.

In some instances, the items are not exactly equal. SRI strongly recommends evaluating data sheets of the products you are comparing before purchasing the product. Infineons cross reference search lets you easily find compatible devices to many competitors devices for your design. The products listed as crosses are recommended starting points for searching for an equivalent-part. SRI cannot, however, accept responsiblity for changes, typos, errors, or omissions. These comparative listings have been checked for accuracy. We may add more 'electronic parts cross-references, for items such as IC chips and relays in the future. We will be adding more units as time allows. SRI is suggesting the list is not meant to be an EXACT cross to other products. Transistor Cross-Reference chart showing stereo receiver / amplifier models that use the same original / OEM output transistors / semiconductors. The purpose of the Cross Refererce Guide is to assist you in searching for a part on our linecard by the manufacturer which is similar in function to products of other companies.
