Substitute Part Grouping Explanation

Substitute parts for the BFC237055472 are qualified based on strict electrical and mechanical parameter matching. The substitution criteria are:

• Capacitance value: 4700 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 400V DC / 220V AC minimum (exact match required)
• Dielectric type: Polyester, Metallized (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Mounting configuration: Through Hole Radial (exact match required)
• Lead spacing: 0.200" (5.08mm) (exact match required)
• Automotive compliance: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The identified substitute part BFC237051472 meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.
