If you search for fan capacitor 12uF you'll find what you need, just match the form factor. People often double the capacitor voltage ratings so you don't blow one on a voltage spike, so 438 is probably the breakdown voltage. I've never seen one with two tolerance ratings, but I'd go with a 5% for the replacement. A lot of companies sell the CB6621, which seems to fit your needs.
