a substitute for FDD8424H
« on: July 29, 2022, 11:03:59 AM »
The FDD8424H is sold out worldwide, and I need 40 pcs. (Well, 20 would doo, I never used both channels anyway).
Is there a relatively direct replacement I am not aware of?

There are these:
https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313&_nkw=FDD8424H&_sacat=0
But who wants to commit a world class product to Chinese counterfeit of unknown valour? They are probably ok, but does anyone here have experience with them?
A minor rework of the board is a possibility, but a hassle, nontheless.

Cheers, Finn Hammer

Hey Finn.

I've been burned by cheaper (smaller package) Mosfets and igbts from AliExpress and eBay. Sometimes they work, just a small gamble with time mostly.

I have a packet of 5 here from rs components if you want them (I have a feeling I might have some AliExpress ones as well, but not entirely sure). A farcry from the 20 you need, bit at least they'll be genuine.

https://octopart.com/search?q=AOD609&currency=USD&specs=0 looks to be about the only in-stock drop-in replacement option. I probably need a few myself (say, a dozen) if that would help get you to the minimum free-shipping order value, DM me if that's of interest (also, please don't buy the whole digikey stock if you don't need them!).

oneKone, Thank you for your outstandingly generous offer, due to hydrons post, I will not need them, but thanks anyway!

Hydron,
Wonderfull! I got them from Arrow, they offfered free shipping, like Mouser often doo these days. So Digikey is still 184+
Thanks a lot!

Arrow isn't an option for private purchases to the UK since brexit, yet another casualty of idiots and lies. I can (and have) ordered to NZ when I'm about to head there to see my family though, with the added bonus of not paying VAT as long as I keep the arrow order under NZD400.

Good to hear you got them - seems that someone went through and cleared out everyone's inventory overnight, including all the arrow and digikey stock. I didn't get a digikey order ready in time (had to meet minimum order quantity for free shipping, otherwise I'd be paying 3x more shipping than in parts!), but I have a old UD2.x to salvage some from if needed, which should keep me going in the meantime (digikey is also showing more stock arriving in a couple of weeks).

Pretty strange about the hoarding of parts from Digikey and Arrow. Arrow in particular, because they were supposed to have 2000 in stock when I put in my order.
