The list will be updated for the next release of the FAQ, hope youĬopyright (c) 1995, 1996 by Dave Roberts. I have managed to track down, so hopefully it will all be correct andĪccurate to my knowledge, any additions can be e-mail'd to myself and Does anyone have specs for Q5119 Seeburg 61-309691 NPN. I thought John at Flippers had a cross reference, but I cannot. filtering system for the supply line which would account for my hum on that. I also bought the Tower's FET selector as well The internet is great, but I still like to browse through specifications in a book now and FAQ: SMD Transistors/Diode cross-ref Surface Mount (SMD) Transistors/Diode FAQĪll the above information has been gathered from multiple sources that On an SHP3 amp from an STD-4, I have Q5119 looks dead which acts as a. For GBP12, it's a bargain so I have placed an order. How to choose a replacement for a bipolar transistor TOTAL: 139878 transistors. I just took a look on Amazon.the Tower's International Transistor Selector is still available The latest revision seems to be December 2008 and it includes SMT transistors. Some circuits just will not behave without a very close equivalent part. This is crucial for good equivalent selection. In the content you can find all kind of electronic. Description: Introduction Date: FebruECCN: EAR99 Country of Origin: China Halogen Free: Compliant Estimated EOL Date: Obsolete / End of life Alternative Parts ( Cross-Reference ): Cross. One thing I did learn all those years ago, was to read the schematic and decide how critical the components specifications were to correct operation. The famous transistor cross reference book is the Philip ECG semiconductor master replacement guide. pH sensors based on a nanostructured ion-sensitive field-effect transistor have characteristics such as fast response, high sensitivity and miniaturization, and they have been widely used in biomedicine, food detection and disease monitoring. Transistors - TRANSISTORS - Transistors (BJT) - Single - MMBT200 - 023727-MMBT200. SMD stuff is too modern for it though so I then have to fall back to internet searches. The internet has changed searching for equivalents but I often find the Towers book faster as I grew up with it and know many favourite equivalent transistors. It lists the transistors specifications and any equivalent (but not all) You can flick through various ranges of transistors and select a suitably specified part. I still have my copy from the 1980's and it still serves me well. In the UK when I worked as a 'Saturday lad' in an electronics shop, I used the 'Towers Transistor selector' book. Substitution of RF power devices needs to be approached with a great deal of caution,& preferably with a Spectrum Analyser on hand. Modern devices as a rule,are better spec'd than older ones,so a common modern type may replace an old special type. The 'MASTR' list of LBIs Over 6 Gigabytes of free downloadable GE Technical Manuals in PDF format, including LBIs, Datafile Bulletins, and Product Code Indexes. In more complex circuits,have a look at what devices other manufacturers use in similar circuits-there may be a common device which will do the job. If it is something simple,like a lamp,LED,or relay driver,you can probably replace it with a more common type without any drama. Top Results (6) Part ECAD Model Manufacturer Description Datasheet Download Buy Part BM1Z002FJ: ROHM Semiconductor AC Voltage Zero. Feeds Parts Directory Manufacturer Directory. If you can't find a listed equivalent,one good philosophy is to look at the circuit the device is used in. transistor cross ref datasheet, cross reference, circuit and application notes in pdf format. Not only did they often disagree,but by the time you had tracked from one book to another,the specs on the final one you turned up were many times quite different to the original. At one of my earlier jobs,we had semiconductor equivalents book from several sources. Good luck finding anything that will do that!(though it must be out there somewhere) Many times the equivalents shown in the various books are harder to find than the original component.
