Substitute Part Grouping Explanation

Substitution eligibility for the F339MX253331MKI2B0 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 3.3 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage ratings: 630V DC / 310V AC (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Operating temperature range: -55°C to 110°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Physical dimensions and lead spacing: 31.50mm × 18.00mm with 27.50mm lead spacing (exact match required)
• Termination style: PC Pins (exact match required)
• Application category: EMI, RFI Suppression (exact match required)
• Ratings classification: X2 (exact match required)

The substitute part BFC233820335 meets all these criteria and is therefore classified as a parametric equivalent.
