I have an old Technics SU-V5 amplifier from 1980. It has through hole capacitors with very thin legs. All new capacitors are snap in and their legs are very thick. They won't fit in the PCB. How do people replace capacitors in such an event?

    \$\begingroup\$ All new capacitors are snap in - Uh what? That's news to me. Several thousand vendor results as well as most PCBs I own say otherwise. \$\endgroup\$ – Reinderien Jan 21 at 21:16
  • \$\begingroup\$ Just buy the right capacitor. When you need new tyres for your V8 car, what do you check? \$\endgroup\$ – Andy aka Jan 21 at 22:06
  • \$\begingroup\$ I've run into this many times. Just take a good cutter and trim the pins down enough to fit in the PCB. Be careful not to stress the mechanical connections. \$\endgroup\$ – Kyle B Jan 21 at 22:17
  • \$\begingroup\$ No all the big capacities are snap in I found 8200 63V, 10000 63V all snap in. I think I'm gonna try to trim the pins down thanks. \$\endgroup\$ – V8 Power Jan 21 at 23:26

There will be little difference between the two, if they fit mechanically then you could solder the snap in capacitor. The most important thing is to match the ESR, and make sure the voltage rating meets or exceeds that of the "old" capacitor. The last thing is if the capacitor is a bypass capacitor, then it needs to have a capacity greater than that of the old capacitor.

If the capacitor is used for filtering, then the value must be matched.

The new capacitor only goes to 50V on it's rating, this could be a problem.
