Where to find electrical components from my ECU board?

[PeterA]

I have, obviously over heated a Fet when I was removing it from a donor ECU to put into my ECU and the car did not start after I did the transplant.

I have replaced a few other parts off the donor board and the car started and drove every time, sigh.....

The part I need is called 55199. It's like 2 bucks, but from china, which means 5-20 days to get here. I need my car now.

Are they any parts like this stocked somewhere in Australia or NZ or the USA, somewhere I can get it faster?

This link below shows the part that I need.

Try RS components. They stock heaps of odd parts like that and are genuine sources, free delivery too. China ebay semi conductors are almost certain to be a cut down clones not rated anywhere near the claimed specs.

Years ago when I did some part time work in an audio workshop doing amps and stuff, we smashed open many china copies of fets and transistors and typically the die size was half to 1/4 of the size of genuine parts of the same type. It was no wonder those parts regularly blew up.

I can second that, I've swapped parts on the vane dissy machine I have here multiple times, when one cap blew I made the mistake of changing them all, I've had to diagnose & swap bits on a regular basis since, parts bought from jaycar, which turns out to be all chinese poo.

Another good source for parts is Element 14, used to be called Farnell Electronics, they're in Chester Hill Sydney.

That 466 means its manufactured by delco electronics, usually under license. They dont publish the details of what it really is and 55199 is their internal number. Normal stores wont have this chip as the only application for that part number is the ECUs delco put them in. If you can figure out what its mainstream ID is, then you'll be fine, but that is not normally possible. I's suggest the best source is, unfortunately, another ECU.

55199 is also used in VX and VY flash PCMs. Might be in other ECM and PCMs as well.

I agree with antus. when dealing with specific components most of the semi conductor suppliers hide there interlectural property and therefore spec are shady. There are publications later that sometimes do have this information in there for refubishment etc after the warranty period for the life of the product. Unfortunately seldom does this happen with ECU hardware. thus you will probably will not find the true nature of these beasts. specialist equipment is generally the worst when it comes to repairs. alot of guess work and bench testing is required. seeing the scale you are on (ie single point) new ECU will be the easiest option both from a time perspective and a functional one.
