BFC246751683 Equivalent & Substitute Parts

Part Overview

The BFC246751683 is a 0.068 µF film capacitor manufactured by Vishay Beyschlag/Draloric/BC Components, rated for 100V DC operation with ±10% tolerance. This polyester metallized radial capacitor is designed for general-purpose applications requiring stable capacitance across the -55°C to 105°C operating temperature range. The part maintains Active product status with 974 units currently in stock.

Substitute parts become necessary when the original component experiences supply constraints, extended lead times, or when application requirements demand higher voltage ratings or alternative compliance certifications while maintaining the same capacitance value and tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

The 160683K250C-F from Cornell Dubilier Electronics qualifies as a direct substitute based on the following alignment of critical parameters:

Matching Parameters:

• Capacitance: 0.068 µF (identical)
• Tolerance: ±10% (identical)
• Dielectric Material: Polyester, Metallized (identical)
• Operating Temperature Range: -55°C to 105°C (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial (identical)
• Lead Spacing: 0.394" (10.00mm) (identical)
• Termination: PC Pins (identical)
• RoHS Status: ROHS3 Compliant (identical)

Enhanced Specification:

• Voltage Rating - DC: 250V (exceeds 100V requirement)

The substitute part maintains all functional and mechanical compatibility while providing a higher voltage rating margin, making it suitable for applications where the original part is unavailable or where increased voltage headroom is beneficial.

Parameter Comparison

Engineering Selection Recommendations

Both the BFC246751683 and 160683K250C-F maintain Active product status with full ROHS3 compliance and REACH Unaffected certification, ensuring regulatory alignment for current and future applications.

The 160683K250C-F provides enhanced voltage margin with a 250V DC rating compared to the 100V DC specification of the original part. This higher voltage rating does not compromise any functional parameter and maintains identical capacitance, tolerance, temperature range, and mechanical compatibility.

Physical dimensions show minor variations: the substitute part is 0.020" longer and 0.177" shorter in height. Lead spacing remains identical at 0.394" (10.00mm), ensuring direct PCB footprint compatibility without layout modifications.

Selection between these parts should be based on supply availability and application voltage requirements. The substitute part is suitable for direct replacement in circuits operating at or below 100V DC, with the additional voltage rating providing design margin.

Frequently Asked Questions (FAQ)

Q: Can the 160683K250C-F replace the BFC246751683 in a 100V DC circuit?

A: Yes. The 160683K250C-F is rated for 250V DC, which exceeds the 100V requirement. All other electrical parameters—capacitance, tolerance, temperature range, and dielectric material—are identical, ensuring functional equivalence.

Q: Are there PCB layout considerations when substituting these parts?

A: Lead spacing is identical at 0.394" (10.00mm) for both parts, so no PCB modifications are required. However, the substitute part has different length and height dimensions. Verify clearance in the component mounting area, particularly if space constraints exist around the capacitor location.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the BFC246751683 and 160683K250C-F are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the tolerance specification for these capacitors?

A: Both parts carry ±10% tolerance on the 0.068 µF capacitance value, meaning the actual capacitance will fall between 0.0612 µF and 0.0748 µF.

Q: Are these parts suitable for AC applications?

A: These are film capacitors with AC voltage ratings of 63V (BFC246751683) and 160V (160683K250C-F). Verify that your AC voltage requirement does not exceed these ratings. For DC applications, use the DC voltage ratings of 100V and 250V respectively.
