Can I replace a 200V capacitor with a 250V capacitor?

Yes. A 250V capacitor can safely replace a 200V capacitor as long as the case size, pin pitch, and capacitance match. The higher voltage rating provides more headroom and potentially longer service life.

What does snap-in mounting mean for electrolytic capacitors?

Snap-in capacitors have thick rigid pins that insert through PCB holes for wave soldering or hand soldering. They use a standard 10mm pin pitch and are designed for through-hole mounting in power supply applications.

How do I choose between 35x50, 35x55, and 35x60mm sizes?

All three share the same 35mm diameter and 10mm pin pitch, so they fit the same PCB hole pattern. Choose based on available chassis height clearance and required ripple current or lifetime rating.

Is this capacitor suitable for audio amplifier power supplies?

Yes. The 250V version is suitable for ±75V to ±85V dual-rail Class AB amplifiers as a main reservoir capacitor. The 200V version suits ±60V to ±70V rails and tube amplifier B+ filter stages. Always observe polarity.

Replacement Notes

Upgrading 85°C → 105°C series is a safe, beneficial swap (longer life, lower ESR).
Never install polarized capacitors in signal coupling or AC paths.
Reverse polarity connection will cause vent rupture and capacitor failure.
