331 1KV Ceramic Capacitor vs 331

Hello! I'm sorry for this question, but I'm noob in electronics and don't have any experience with ceramic Capacitors. I'm repairing a PC power supply, and i have a burned ceramic Capacitor that has "331 1KV" written on it. And on the other hand, I have a unused ceramic Capacitor that just "331" written on it. Can I use this capacitor instead of the burned capacitor?

The 3 digit capacitor code 331 stands for 330 pF. 1KV is its maximum work voltage. Your new capacitor should have voltage not less than 1KV if you don't know actual voltage on the capacitor.
