Substitute Part Grouping Explanation

Substitution of the BFC236521394 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.39 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 100V DC minimum / 63V AC minimum
• Dielectric type: Polyester, Metallized (exact match required)
• Mounting configuration: Through Hole, Radial package
• Physical footprint: 0.413" L × 0.236" W with 0.197" lead spacing
• Operating temperature range: -55°C to 105°C (minimum)
• Termination style: PC Pins (exact match required)

The BFC236621394 qualifies as a direct substitute based on identical electrical specifications, mechanical dimensions, and termination characteristics. The primary distinction is product status: BFC236621394 is active production, whereas BFC236521394 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The BFC236621394 is the direct equivalent for the obsolete BFC236521394. Both components maintain identical electrical performance, mechanical compatibility, and regulatory compliance. The BFC236621394 is preferred for new procurement due to active production status, ensuring supply chain continuity and availability. Both parts satisfy ROHS3 compliance requirements and operate across the full -55°C to 105°C temperature range. The transition from MKT365 to MKT366 series represents a product line evolution within the same manufacturer, with no functional or dimensional deviations affecting circuit performance or PCB layout.
