Hi, I have two burnt-out components on my Arduino Mega. I found them on the online schematic, but I'm not sure where to look for them.

They are:

D1:

DIODE-SMB (DIODE-)

C6:

CPOL-EUSMCD (CPOL-EU)

I looked at the top of the components and they had the following labels:

D1:

GW
4007

C6:

A476D
10F60

Does anyone know where I can find replacement parts?

Digikey.
Search for 1N4007 in SMB package.
Search for aluminum cap in surface mount package, probably 100uF, 25V, maybe 5mm?

I think I found an appropriate capacitor:

Manufacturer:   Murata Electronics North America
Manufacturer Part Number:   ECASD91B107M012K00
Description:   CAP ALUM 100UF 12.5V 20% SMD
Lead free / RoHS Compliant

However, SMB packaged diodes for some reason aren't the same size as the one I measured on the board. It appears to match an SMA packaged diode.

I found this diode which appears to be the correct size:

Manufacturer:   Diodes Inc
Manufacturer Part Number:   S2BA-13-F
Description:   RECTIFIER GPP 100V 1.5A SMA
Lead free by exemption / RoHS Compliant

Is there anything glaring that would suggest why either of these won't work (I'm a mechanical engineer normally so I don't have a lot of electronics experience)?

If they fit on the board, they will do fine.

How did you damage the input power section?

[Reply #4 on:]

A battery pack had the red wired as ground and black as hot, so I accidentally plugged it in backwards These were the only two components which had visible damage, hopefully the board will work after I replace them.

Oooh, nasty!
Hopefully the diode took the brunt of it.

SMA is smaller than SMB but it should fit on the pads enough to solder

Got the two parts on and the chip works like a charm
