Picture of the damage… 9 parts, 2 detonated<\/p>\n\n\n\n

That is definitely a different part number that we replaced on the MPPT board of SN002.

No Stock at Mouser (on order)
You CAN NOT order the -4 part

Google says you can only get them from FleaBay and Sketchi-bah-bah but check out what Octopart says!

Oh bugger – that is an AG (automotive Grade)
At first they seem ALMOST symmetrical but they are not. Read all the specifications and see that we could probably replace all of them with these, but mixing them may result in some miss-match turnon. Bugger.

They are NOT THE SAME! It is not just a part that went thru additional screening and qualification, they ARE different parts. Read all the specs.<\/p>\n\n\n\n

grrrr….<\/p>\n\n\n\n

Manufacturer has them (Why does Octopart not search this?!?)

DOH DOH DOH
* First they give me a coupon code that does not work
* Then they make me go all the way thru checkout before telling me they are out of stock
* Idiots<\/p>\n\n\n\n

Ok… Ebay it is… but they are 2 for one there, S K E T C H … B R O – and its like a month of shipping, not going to happen<\/p>\n\n\n\n

GAHHHHH!<\/p>\n\n\n\n

Lets buy 9 of the Automotive Grade and replace them A L L – going to be a lot more work – GRRRRR<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Ok, I had to order all 9 to replace them as a pack to play it safe. The others were probably punched H A R D anyway – and – what is messed up is that we still dont have root cause!!!!!

ACK – ok, $100
They are on the way Second Day UPS (best value)
