Greg, I think that is a garden variety 100nF X7R 50v capacitor.
?Yes, you can replace it with a leaded capacitor, but with caution.
?The adhesion of the pad traces to the board can easily fail when attaching a leaded component where an SMD should be. Any attempt to form or bend one lead after the other has already been soldered may result in damage. You might lift the pad and trace up off the board.
Replacing the damaged capacitor with another SMD is the better solution IMO.

Good morning Group,
?
Hoping for information and validation of a proposed repair for a problem I created while assembling my new QMX kit.
?
I cracked SMD 0603 capacitor C513 (its in the TXBias input area of the Low Pass Filters section). It looks like a typical by-pass capacitor to me, BUT I am not an EE or talented RF designer.
I was able to float it off and cleaned up the solder pads.
?
I wanted to see if anyone could give me the basic specs (tolerance and V rating)
AND . . .
Get opinions/advice on whether I could replace that component with a small, regular 0.1uf ceramic capacitor with lead wires. I ordered a 10 pack from AdaFruit of common, 0.1uf bypass capacitors (+/- 20% - 50V), I'd preform the leads, insulate with quality shrink tubing, tape the component down and then tack and solder the leads to the pads. Figured I'd add a drop of hot glue to the 'face' of the component to make sure it stays flat on the board during the rest of the kit assembly, and getting everything in the enclosure.?
I'm almost certain I can solder the leaded component onto the pads and have it lay flat in a nearby empty area, rising above the board at no more than 2 - 2.5 mm. I'm not so sure I can successfully solder in a replacement? 0603.? 74 year old eyes, hands and fingers aren't what they used to be. I do have a good soldering irons and a magnifying headlamp (up to 15X) and can still assemble, modify and repair tiny through-hole component 'stuff' pretty well.?
