Nichicon LK Snap In Capacitor: What's a Modern Replacement?

I need a snap in capacitor to replace a Nichicon LK series. I can't find that series anywhere except eBay for a pretty high price (like, $15 for two ) so I was wondering if there was a replacement. Nichicon does not list it on their website or substitution page.

I can't even find a data sheet for the LK series, but the Panasonic TS-HA series looks good. Anyone have experience with that capacitor?

Any specific reason why you want that type of cap? Wouldn't you just look for voltage/capacitance rating and physical size (too make sure it'll fit) and go from that?

Well, I've never bought any snap-in capacitors. I use low impedance, long life Panasonic FM or Nichicon HE for everything, but I don't know what a snap-in equivalent would be. The Panasonic TS-HA really seem like the only option.

They are used in the power supply section of a compressor.

Well, the schematics aren't available anywhere online, if that's what you are asking. I guess it's a filter capacitor because of its size. Here is a link to an eBay auction for the original capacitors. That's not a bad price, but I don't need 10:

Nichicon LK 3300uF 35V

So it looks like the stock part was 3300@35v and the case size was 22mm/d & 25mm/h

Lots of snapin options, most everything has higher capacitance in the 35v range but thats ok. Just don't get one that physically won't fit and you'll be fine.
