BFC247952513 Equivalent & Substitute Parts

Part Overview

The BFC247952513 is a 0.051 µF film capacitor manufactured by Vishay Beyschlag/Draloric/BC Components, rated for 400V DC operation with polypropylene metallized dielectric. This radial through-hole component is designed for high-pulse and DV/DT applications requiring long-life performance across industrial temperature ranges. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent capacitance and tolerance specifications can be maintained while accommodating different voltage ratings or inventory availability requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC247952513 is determined by strict parameter matching across the following criteria:

Critical Parameters (Must Match):

• Capacitance: 0.051 µF
• Tolerance: ±5%
• Dielectric Material: Polypropylene (PP), Metallized
• Operating Temperature Range: -55°C ~ 105°C
• Mounting Type: Through Hole
• Package / Case: Radial
• Lead Spacing: 0.591" (15.00mm)
• Series: MKP479

Allowable Variation:

• Voltage Rating - DC: Equal to or greater than 400V

The BFC247962513 qualifies as a parametric equivalent because it maintains all critical parameters while providing an elevated DC voltage rating of 630V, which exceeds the original 400V specification. This higher voltage rating does not compromise compatibility in applications designed for the original part's voltage class.

Parameter Comparison

Engineering Selection Recommendations

Both BFC247952513 and BFC247962513 maintain Active product status with identical RoHS3 compliance and REACH unaffected certifications. The BFC247962513 provides equivalent functionality with enhanced voltage margin, making it suitable for applications where the original 400V DC specification is met or where additional voltage headroom is beneficial. Both parts are manufactured within the same MKP479 series by Vishay Beyschlag/Draloric/BC Components, ensuring consistent quality and performance characteristics. Selection between these parts depends on application voltage requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can BFC247962513 be used as a direct replacement for BFC247952513?

A: Yes. The BFC247962513 maintains identical capacitance (0.051 µF), tolerance (±5%), dielectric material (polypropylene metallized), operating temperature range (-55°C ~ 105°C), and physical dimensions. The 630V DC rating exceeds the original 400V specification, providing compatibility in all applications designed for the BFC247952513.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions of 0.728" L x 0.256" W (18.50mm x 6.50mm), maximum seated height of 0.610" (15.50mm), and lead spacing of 0.591" (15.00mm). PCB layout and mounting requirements remain unchanged.

Q: What is the significance of the voltage rating difference?

A: The BFC247962513 operates at 630V DC compared to the BFC247952513 at 400V DC. This higher rating does not affect performance in circuits designed for 400V operation. The elevated voltage specification provides additional safety margin and may extend component life in high-stress applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both BFC247952513 and BFC247962513 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What applications are these capacitors designed for?

A: Both parts are specified for high-pulse and DV/DT applications requiring long-life performance. The polypropylene metallized dielectric and radial through-hole configuration support industrial and power electronics applications across the -55°C to 105°C operating temperature range.
