Mpf102 Vs 2n7000, Are you after a JFET or a MOSFET? The MPF102 is similar to the 2N5457 and 2N5458.
- Mpf102 Vs 2n7000, Q3: is a 2N5088 which is an NPN transistor, with an hFE of 300 (and it's own gain curve), while you might be able to substitute a 2N3904, the circuit won't sound the same. This is not required for the MOSFET. Jun 25, 2005 · To be honest I would maybe reduce or omit Rs for the MOSFET circuit because the reason it is there in the first place is to provide negative bias for the JFET transistor configuration. I. Q2: is a JFET MPF102 which is obsolete and you might want to use a substitute if you can't find one. If you know what to look for, a nice substitute is fairly easy to find. Fortunately there are good alternatives, but these require a little hunting and gathering. You probably want to choose another process 50 variant, the most common part numbers being 2N4416 Building an EQD o))) Life, huh? It’s pretty killer, I’ve used k117 which sounds almost identical and 2n5457 which is a slightly different flavor of the same thing. What to Look For. Good luck!! Hey all, I'm planning to do quite a few builds in the near future that require the J201 and/or 2N5457. e. In particular, replacements for the 2N7000 and P-channel equivalent, but anything would be appreciated! (Some other suggestions: standard / high impedance / high gain op-amps, NPN & PNP high-beta and fast-switching transistors, fast diodes, etc. Start by checking out catalog pages at Mouseror another vendor. 13 hours ago · Hi MPF102 is a JFET. All that is to say that virtually any JFET will work in this application. If you want a MOSFET, try the 2N7000 or BS170. 3 Volt MCU circuits to switch higher voltage devices? Background: For 5 Volt microcontroller based prototypes and experiments, my go-to soluti MPF102 is generally considered to be the floor sweepings of process 50. ) For instance: Sep 8, 2021 · Find or Create a Group English Help Log In Sign Up. This page explains how I chose four parts from Radio Shack and Mouser that tested pretty close to an MPF102. What should you do? Substitute! Radio Shack once sold four NTE equivalents for the MPF102. These parts were available over the Web, with free shipment to your local store. Are you after a JFET or a MOSFET? The MPF102 is similar to the 2N5457 and 2N5458. Mar 31, 2024 · My experience was that the 2n5457 and thd j201 had a slight difference in gain, but the mpf102 was remarkably lower that the other two. Researchis the name of the game. Feb 1, 2016 · J-FETs do infact behave slightly differently than Mosfets (mosfets have even higher gate impedance) so replacing with a 2N7000 won't make it work exactly the same. , after the production run has been sorted by performance into different part numbers, the junk that's left is lumped together and sold as MPF102. I've read some posts about this but wanted the opinions and experiences you all have had, what are good replacements for those 2 transistors? Jun 16, 2022 · This post contains details about 2N5952 jfet pinout, equivalents, specs, explanations, features, where and how to use it and other useful info. I settled with the 2n5457 being in the middle. cheers What are the popular equivalents to the 2n7000, for 3. Also if you can’t find BS170, you can use 2n7000 as for these purposes they are exactly the same, except the pin out is reversed so just turn it 180 degrees. cz1zdl, kla, tnvxgn, 22ovp, d4zktad, 3sh6, 1vezfc0, af, 6ub, lar,
