Some small switchmode power supply chips want the filter cap ESR to be
between certain limits, but they're not very common. Generally there
shouldn't be a problem with new caps having lower ESR than the
originals.

Is it always OK to replace a regular electrolytic capacitor with a low
ESR version in things like the vertical and horizontal sections of a
CRT monitor or TV?

Are there any cases where low ESR electrolytics should never be
substituted?
