Three values are usually enough: the capacitance (in pF, nF or µF), the working voltage and the dielectric type. For voltage, allow a margin: on a 12V rail use a 25V rated part, on rectified mains filtering go up to 400V. A capacitor working too close to its rated voltage runs hot and ages quickly.
For SMD parts, check the package before ordering: 0402, 0603 and 0805 are not soldered the same way. Sizes and dielectrics are grouped under SMD Capacitors, filtering values under Chemical and Power Capacitors.
NP0/C0G is the most stable with temperature and voltage, reserved for filters and oscillators where the value must be precise. X7R is a good compromise for decoupling, while Y5V can lose a large part of its capacitance under DC voltage and heat.
Take at least 1.5 to 2 times the DC voltage actually present in the circuit. On mains, use parts designed for AC (X2, CBB61) and never a standard electrolytic.
Only for small values and if size allows: ceramic is unpolarized and has low ESR, but its actual capacitance drops under voltage depending on the dielectric. For smoothing large values, keep an aluminum electrolytic.
A lug-terminal run capacitor or a CBB61 polypropylene type, matching the µF value and the AC voltage shown on the old one (for example 2µF 450VAC). See <a href='/category/condensateurs-film-polypropylene'>Polypropylene Film Capacitors</a>.
Technology (ceramic, electrolytic, film), voltage, tolerance and manufacturer all play a role: a low-voltage Y5V ceramic does not cost the same as a branded high-capacitance X7R or a power capacitor for a motor.
