Secrets Of Mosfet Cross Reference and Replacement Guide

A Semiconductor Replacement Guide

Searching for the right mosfet cross reference or datasheet, one has to look for a semiconductor transistor replacement data book and not the Philip ECG master replacement guide. Almost all the transistor replacement book will published out the specification of a particular components such as type of component it belong whether it is a fet, scr, bipolar transistor, horizontal output transistor and also the voltage, ampere, wattage, ohm, frequency and suggested substitution part number.

From my experienced, the substitution part number that was recommended by the data book is not always 100 % match. If you have the time, I would like to suggest to you that, find the right part number by yourself rather than depending on the transistor data book.

It is the same when you look for horizontal output transistor (HOT) specification which doesn't mean that the bigger specification, the better the substitution part number is. In searching for Mosfet cross reference, you have to look at the ohms value which is provided by the transistor data book besides the specification of voltage, ampere and the wattage. The replacement, besides the same or higher in voltage, ampere and wattage, one should also consider the ohms value. The ohms value has to be as close as possible.

If the original fet part number is 1 ohm then a good replacement mosfet must have the ohm values between of 0.5 to 1.5 ohm. Do not substitute it with a too high or too low ohms value as this will make the mosfet run warmer and eventually blow the mosfet itself. Even though you can get a replacement with a higher voltage, ampere and wattage, if the ohms value is too low or too high, the mosfet will still burnt after on for quite a while.

True case study- An Epson inkjet printer sent in for repair with the complaint of no power. Checking the switch mode power supply found the power mosfet shorted. I don’t have the original part number at my work place so I substitute it with a mosfet with a higher voltage, ampere and wattage and a higher ohm value than the original one with the help of my transistor cross reference guide.

It runs well for sometimes before it breakdown again. After two weeks the customer brought back the printer with the same complaint which is no power. Upon checking the power side I found the same mosfet gave up again. Substituting with another mosfet part number that have a similar specification especially the ohms value solved the printer no power symptom.

Specification with larger voltage, ampere and wattage don’t guarantee that the replacement mosfet will work. So, taking the mosfet ohms value into consideration, you will have a higher chances to repaired the equipment and sometimes the replacement mosfet will also last longer.

Antonov An 990 Access

The real An-225 was called "Mriya," the Dream. In a poignant and perhaps unintentional way, the An-990 carries that torch into the digital age. With the real An-225 now gone, the only place you can still experience a "Mriya" is in a simulation. The An-990 takes that concept and runs with it, creating a dream so big that it could only ever exist on a screen. It’s a fun, over-the-top tribute to the spirit of "what if" that drove the original Antonov designers.

The is a legendary, massive aircraft that holds the title of the largest plane ever created within flight simulation history. While the real-world Antonov company is famous for engineering colossal real-world cargo lifters like the Antonov An-225 Mriya and the Antonov An-124 Ruslan, the An-990 "Juggernaut" is a strictly fictional, community-created behemoth designed for the X-Plane flight simulator platform. ✈️ What is the Antonov An-990? antonov an 990

The An-990 concept emerged as a proposal for a next-generation "super-heavy" airlifter that would move away from the specialized role of the Mriya and toward a more versatile, mass-producible (relatively speaking) strategic transport. It was envisioned as the ultimate solution for global logistics, capable of carrying payloads that no other aircraft—including the C-5 Galaxy or the An-124—could manage.
