Substitute Part Grouping Explanation

Substitution eligibility for the CM05FD221JO3 is determined by strict equivalence across the following critical parameters:

Capacitance Value: 220 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage Rating: 500 V (exact match required)
Dielectric Material: Mica (exact match required)
Operating Temperature Range: -55°C to 125°C (exact match required)
Mounting Type: Through Hole (exact match required)
Package Configuration: Radial (exact match required)
Lead Spacing: 0.232" (5.90 mm) (exact match required)
Physical Dimensions: 0.461" L x 0.201" W; Height 0.382" max (exact match required)

Two substitute parts meet these criteria and are classified as parametric equivalents within the Cornell Dubilier Electronics product family.
