J113 vs mpf102 000 ohms. Dec 22, 2018 · 9/28/98 - More on the biasing resistors. For the others, go for the SMD ones + adapter boards! Voltages below 9 volts are too low for most FETs. . Symbol . 2K resistor. At 6 volts, you'd probably lose all your gain. An exceptional substitute for the MPF102, 2N5457, and J201, maintaining the same pinout orientation. We don’t have any data for the J112, but the Idss will be even higher than the J113. MPF102 Features. 000. Apr 19, 2019 · The closest equivalent for NTE457 is the J113 FET. I think it's just plain obsolete. It is mainly built for the amplification in VHF region of frequencies. For that one, I've heard J113 is a good sub, and it's still being produced in through-hole format. Genuine J113 JFET is now available. It's also the defacto device (along with the same die in a metal can, the U310 which is what I use) for almost all active whip-amps that use a JFET as the input device. You can find it in some suppliers that still have them in stock or you can replace them with other new designs like J113, NTE457, etc. Not sure on the availability though. MPF102 Marking Diagram. Hence be careful which employing one in your designs. There's little if anything worth considering any more as a replacement for 2SK170 among the standard industry JFETs. 3 – Maximum current. On hand right now I have 5457, 5458, 5952, and j113. The MPF102 has a lower gain than the J201: An advantage, because it won't overload as fast as the J201 does. (Do you want to play through it, or detonate it?) For an MPF102, the ideal voltage is 15 volts. I have found that the MPF102 FETs I got from JameCo are way different in terms of biasing! To get the same 4. They are a fantastic replacement. I don't think you can get MPF102 in surface mount form. The main component or heart of this active antenna amplifier circuit is MPF102 N-channel JFET due to its high input impedance and low noise. Features / Technical Specifications: Package Type: TO-92, SOT-23; Transistor Type: N Channel JFET (Symmetrical) Maximum Drain to Gate Voltage: 35V; Maximum Reverse Gate to Source Voltage: –35V Finding substitute JFETs that work in the Hawes MPF102 preamplifier. The MPF102 can provide a stronger signal into a lower impedance load. Transistor Type: JFET N Channel. As others said 2N3819, but I've found the J113 does the job in most J310 and MPF102 circuits Reply reply 1Davide • J310 Nov 15, 2017 · As an example, the J113 JFET transistors we use in many of our effect pedal kits have an input impedance in the range of 1. This is the maximum current the JFET can let through when the resistive channel is fully open. With a Radio Shack MPF102, I use a 2. MPF102 Pinout. Links to high-impedance circuits with common BJT transistors. And like many other JFETs, the MPF102 is a low-noise device. The clone FETs available in the market does not seem to follow the datasheet strictly. Jan 22, 2024 · It stands out for its simplicity, utilizing a single MPF102 transistor, alternatives like NTE451 or J113 JFETs, and a few other components. The MPF102 N-channel JFET, known for its high input impedance and low noise, is the key driving this active antenna amplifier circuit's excellence. Aug 23, 2021 · Sadly, the MPF102 is no longer in production. MPF102 CAD Model. If it’s an N-channel JFET, this happens when the Gate-Source voltage Jan 23, 2015 · One of the problems with the FJN598J as a substitute for MPF102/2N5457/J201 is that the pinout is not compatible. So on a PCB meant for an MPF102, adapting it is possibly but messy. 6V at the drain, I have to use a 680 ohm resistor. SUPPORTER Oct 15, 2022 · I have some other Jfet options though and plan on just doing some auditioning tonight, I’ll have trimmers on the board for biasing. So, where does this leave us? Well, we could consider substituting a low-Idss PF5102 for a 2N5457 in any circuit design. Sounds like the 5457 is a good choice which I have some of. I bought my last batches of all of them when the EOL was announced. Sep 16, 2017 · I've used his J201 SMDs boards and transistors a few times. It's a good starting place. Dec 16, 2022 · This circuit is simple and easy to build using only one MPF102 transistor or NTE451 Or J113 JFETs. BF245 is not available in my area. Genuine J113 JFET is now available. I can recommend it too. Package Type: TO-92 Jan 26, 2015 · Can I use BFW10/11 in place of BF245A? thanks. Quite a big difference. Mouser has 'em. Footprint . I can recommend chromesphere's store DIYGP. But other than that it can also be used in verity of other audio amplification related applications. Operation at more than 18 volts is probably too inconvenient for battery power. Aug 9, 2020 · MPF102 is a very famous JFET transistor used in many commercial devices as well as educational and hobby projects. and a few other parts. 3D Model. But just curious which jfets other would use in place of. Pin out is different, and it depends on the application but recently I used a j201 in place of an mpf102 beacis has a great Pinout guide for most trannies made up until a few years ago. Thanks The J310 is a high-Idss device, much higher than the general JFETs like your MPF102, 2N3819, 2N4416, etc. Jul 30, 2019 · Thinking Yup, the J113 is not a drop in replacement for the K170. MPF102 can be an excellent replacement. Anyway, you're getting close to the maximum for the FET, 25 volts. From ammo reel. 000~10. We could possibly substitute a J112 or J113 for a 2N5457 provided our circuit is immune to the Idss difference. twzjicnkwhiqztpmikogagyyqddlaootylhieedvqzrhkjzyvgideghfgfnfwgkjkccxtoam
