Substitute Part Grouping Explanation

Substitution eligibility for the F1778333M2FCB0 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.033 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage ratings: 630V DC and 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)
• Lead spacing: 0.591" (15.00mm) (exact match required)
• Ratings classification: X2 (exact match required)

The identified substitute part F339MX233331MFP2B0 meets all these criteria and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the F1778333M2FCB0 and F339MX233331MFP2B0 are Active products with full ROHS3 compliance and REACH Unaffected status.
