After a marathon session at distributor's web sites, I found a number of perfect fit replacement caps but still missing a few.Unless they are used for timing like in a soft start circuit, the
values are not critical. Larger values are better up to a point.
For local bulk decoupling capacitors, values are usually selected
based on ESR at high frequency so a lower value solid tantalum
capacitor can replace a larger value aluminum electrolytic capacitor
with a ratio of about 2 to 4.
There is a wonderful selection of SMD caps with tight tolerances for well less than a buck. I could imagine making a tiny little carrier board that would convert the SMD to the right pitch and size to replace an axial cap. Anything wrong with that idea?It is much easier to use radial lead parts by insulating and bending
one lead around the capacitor body.
