Substitute Part Grouping Explanation

Substitution for the BFC236552183 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.018 µF (exact match required)
• Voltage rating: 400V DC minimum
• Dielectric type: Polyester, Metallized
• Tolerance: ±5%
• Mounting configuration: Through Hole, Radial package
• Physical dimensions: 0.394" L x 0.177" W with 5.00mm lead spacing
• Operating temperature range: -55°C to 105°C minimum
• Termination: PC Pins

The BFC236652183 meets all substitution criteria as a direct equivalent, with the primary distinction being its active product status and updated series designation (MKT366 versus MKT365).
