Identify this capacitor for replacement

So after I tossed a coolrunner on this Jasper board it didn't boot. I went to resolder everything and somehow (probably my hammer of an iron tip) sucked up this cap. Can someone identify it so I can replace it? Preferably a solution that isn't a tiny tiny smd.

If you PM me your address I'll be happy to send you a couple. I have a Falcon donor board I can pick them from

I have a couple xenons and a zephyr or falcon. My concern with that is (A) are they the same capacitance as a Jasper and (B) How do I safely remove them. I heatgunned one board and pulled one off and soldered it to the suspect board. However, this did not work. I was going to continue trying this and as a backup, get some brand new ones to remove any doubt on the integrity of the donated caps.

I'm pretty sure Falcon and Jasper share the same caps. I have heatgunned several caps without problem.

If I should guess the capacitance of this specific cap I would say around ~300pf. Guess its a matter of trial and error:)

So I suppose now I'll have to identify whether or not my other donor board is a falcon or not. I may grab 10 or so 300pf SMDs as well as discs and try those. I may try to rewrite the nand with the original and pull the coolrunner in the meantime to remove any question of boot issues due to that.

Yeah... or you try simply bridging the cap pads first. Maybe your system doesn't need it to boot.:)

I understand that they will have a polarity difference. They're so small it's near impossible to tell. The easiest way I suppose would be pulling from a donor board cleanly enough and without dropping it to do an exact transfer. Or a very small sharpie point. I was mostly looking for ideas. I think I have enough to proceed now. I would still like to know the exact part however.

Just as an update:

I realized I only had Xenon donor boards. I decided to try them anyway. I resoldered the cap and knocked off the resistor below the PLL_BYPASS so I also had to transplant that. I still could not boot. I removed the coolrunner and flashed the original NAND back. I then had success booting. Whether or not those are necessary components, I am unsure. What I have learned is that a Xenon is a valid donor board. I have decided not to continue with this board at this time. Out of probably about 50 JTAGs and 10 coolrunners now, this is the worst trouble I've had with a board. On the bright side, it compels me to buy a better and more precise Aoyue iron and a perhaps some magnification setup. I appreciate all of the advice and quick responses I was given. At least the xbox is now functional, albeit without exploit.
