Alternative websites to buy IRLB3034PBF?

[Tymec]

So basically I live in Norway and I want to build a dual 18650 parallel mod and I was going to buy everything from eBay, but as I've read that there are many counterfeits, so I decided to buy parts from fasttech. But here comes the problem, you can't buy the IRLB3034PBF from fasttech. Does anyone know of a website that I could buy them from with low cost shipping as Digikey and Mouser have very expensive shipping.

Also if I would for example buy the mosfets from eBay, what could be the worst case scenario with these mosfets malfunctioning?

Hey Tymec. Search by part number over at http://octopart.com. Many times I've heard of people getting counterfeit components unfortunately from Ebay. A fake part may have poor performance and the component itself may produce excessive heat due to being a higher resistance (RDS ON).

Thanks a lot @david4500

I'm no expert, but often times when MOSFETs fail, they let all the current through. The whole point of using a mosfet is to avoid the button welding itself, and failing MOSFET is even worse. I know the risk is far smaller though, but really, you don't want the mod to fire in your pocket.
