It's a good plan to avoid knock-off parts of any type. Many of old timers have seen counterfeit parts going back 40 years or more. You just need to be careful about where you source your parts. Here in the states, I use DigiKey mostly. I can buy cheaper caps but I prefer to buy from a trusted supplier. Plus, companies like DigiKey and Mouser have a huge selection of caps. So one can select not only value, voltage rating, and lead configuration, but also have the option of selecting manufacturer, ESR, and lifetime hours ratings. I generally only buy Panasonic capacitors because I've grown to trust them. In industrial controls where they are all on the time in a wide variety of temperature extremes, I don't want a cap with a 1000 or 2000 hour rating. I also know that with DigiKey and Mouser, I'll get a genuine Panasonic or Nichicon capacitor if I order one. They cost more than I can get them elsewhere, but I'd rather pay more to know I'm not getting a knock-off. I also know that a new Panasonic cap (like the EEU-TA series) *will* last longer than the original ten year old capacitor with many thousands of hours on it. Even a top quality capacitor is still on borrowed time after 40 years. |
