BFC246928684 Equivalent & Substitute Parts

Part Overview

The BFC246928684 is a 0.68 µF film capacitor rated for 100V DC operation with polyester metallized dielectric construction. Manufactured by Vishay Beyschlag/Draloric/BC Components as part of the MKT469 series, this radial through-hole component is designed for general-purpose applications. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution of the BFC246928684 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.68 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 100V DC minimum (equal or higher acceptable)
• Dielectric type: Polyester, metallized (exact match required)
• Mounting configuration: Through-hole radial (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Operating temperature range: -55°C to 105°C (equal or wider range acceptable)
• RoHS compliance: ROHS3 (equal or better compliance acceptable)

The BFC246706684 meets all substitution criteria as an active-status equivalent from the same manufacturer family, differing only in series designation (MKT467 vs. MKT469) and physical height, which does not affect electrical performance or PCB compatibility.

Parameter Comparison

Engineering Selection Recommendations

The BFC246706684 is the direct functional equivalent for the obsolete BFC246928684. Both components share identical electrical specifications, dielectric composition, and PCB footprint requirements. The substitute part offers the advantage of active production status, ensuring long-term availability and supply chain continuity.

The reduced seated height of the BFC246706684 (16.00mm vs. 18.50mm) presents no compatibility concerns for standard through-hole PCB layouts and may provide marginal benefits in space-constrained designs. Both parts maintain ROHS3 compliance and identical operating temperature ranges, making them interchangeable from a regulatory and thermal perspective.

Frequently Asked Questions (FAQ)

Q: Can BFC246706684 be used as a direct replacement for BFC246928684 on existing PCBs?

A: Yes. Both parts share identical lead spacing (10.00mm), termination type (PC pins), and radial package configuration. The lower profile height of the substitute part does not affect PCB mounting compatibility.

Q: Are there electrical performance differences between these parts?

A: No. Capacitance, tolerance, voltage ratings, dielectric material, and operating temperature ranges are identical. Both parts are rated for 0.68 µF at ±10% tolerance with 100V DC and 63V AC ratings.

Q: Why is the original part obsolete?

A: The BFC246928684 belongs to the MKT469 series, which has been superseded by the MKT467 series (BFC246706684). Vishay has consolidated product lines, making the newer series the current production standard.

Q: Does packaging format affect substitution?

A: The main part is supplied in standard packaging, while the substitute is available in Tape & Reel (TR) format. This affects procurement and handling but does not impact component performance or PCB compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both BFC246928684 and BFC246706684 are ROHS3 compliant, meeting current environmental and regulatory requirements.
