Will this fit a trane 4twb4049e1000b cond unit xb14 (R410a)?

Bojack - I do not have an answer for you based on the Model you provided. The best-case scenario would be to Shut total power off to your AC outside unit, take the cover off and look at the Dual Capacitor that is factory installed. The values in Micro-Farads (capacitance) should be part of the original part on AC unit. You want to pay close attention to the VAC Voltage Value and Micro-Farad value of the original Dual Capacitor. The high number is for the Running Compressor the lower value is for the Blower Fan. The common problem you will encounter is that the higher Value for the Compressor is the one that fails, but due to it being a "Dual Capacitor component", it requires to replace it if Compressor or the Fan stopped working. For Best results, replace it with same exact Values. (Voltage VAC, High and low Capacitance value - commonly -/+ 5% range)

Where is this capacitor made?

The capacitor is Made in China. I installed it a year ago and is still going strong. I saved myself probably about $200 for not having a service tech come out.
