Substitute Part Grouping Explanation

Substitute parts for the BFC247954513 are identified based on the following criteria:

• Identical capacitance value: 0.051 µF
• Identical tolerance: ±5%
• Identical dielectric material: Polypropylene (PP), Metallized
• Identical operating temperature range: -55°C to 105°C
• Identical mounting type: Through Hole, Radial
• Identical physical dimensions and lead spacing
• Identical series classification: MKP479
• Equal or superior voltage rating (DC voltage ≥ 400V)
• Identical AC voltage rating: 200V
• Same termination type: PC Pins
• Equivalent or superior product status and compliance certifications

The BFC247962513 qualifies as a direct substitute based on these parameters, with the distinction of a higher DC voltage rating (630V versus 400V), which provides enhanced voltage margin without compromising any other electrical or mechanical characteristics.
