Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete BFC236521184 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.18 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 100V DC / 63V AC (exact match required)
• Dielectric material: Polyester, Metallized (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Mounting type: Through Hole Radial (exact match required)
• Physical dimensions and lead spacing: 0.413" L x 0.197" W with 0.197" lead spacing (exact match required)
• Termination: PC Pins (exact match required)

The substitute part BFC236621184 meets all these criteria and is classified as an equivalent replacement. The primary distinction is the transition from the obsolete MKT365 series to the active MKT366 series, with packaging available in Tape & Reel format for production environments.
