Substitute Part Grouping Explanation

Substitute parts for the F1778368M2DBB0 are identified through parametric equivalence. The substitution criteria are based on the following key parameters that must match or exceed the original specification:

• Capacitance Value: 0.068 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating - DC: 630V (minimum requirement)
• Voltage Rating - AC: 310V (minimum requirement)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -55°C ~ 110°C (minimum requirement)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial (exact match required)
• Physical Dimensions: 0.492" L x 0.197" W, 0.433" height, 0.394" lead spacing (exact match required)
• Termination: PC Pins (exact match required)
• Application Rating: X2 (exact match required)

Parts meeting all these criteria are classified as parametric equivalents and direct functional substitutes.
