BFC246929124 Equivalent & Substitute Parts

Part Overview

The BFC246929124 is a 0.12 µF film capacitor rated for 100V DC operation, manufactured by Vishay Beyschlag/Draloric/BC Components as part of the MKT469 series. This polyester metallized radial capacitor is designed for general-purpose applications with a through-hole mounting configuration. The part is currently listed as obsolete, making identification of compatible substitute components essential for ongoing design support and procurement planning.

Substitute Part Grouping Explanation

Substitution of the BFC246929124 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.12 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage rating: 100V DC minimum (equal or higher acceptable)
• Dielectric material: Polyester, Metallized (exact match required)
• Operating temperature range: -55°C to 105°C (equal or wider range acceptable)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Termination: PC Pins (exact match required)
• RoHS compliance: ROHS3 Compliant (equal or higher standard acceptable)

The BFC246707124 qualifies as a direct substitute based on full alignment with all critical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The BFC246707124 is a direct electrical and mechanical equivalent to the BFC246929124. Both components share identical capacitance, voltage ratings, tolerance, dielectric material, operating temperature range, and lead spacing. The substitute part is manufactured by the same supplier and maintains ROHS3 compliance.

The primary distinction is product status: the BFC246929124 is obsolete, while the BFC246707124 is active and currently in production. The substitute also features a reduced seated height of 0.630" (16.00mm) compared to 0.728" (18.50mm) for the original part, which may provide a minor advantage in space-constrained PCB layouts without affecting electrical performance or mechanical compatibility.

Packaging differs between the two parts: the original is supplied in standard packaging, while the substitute is available in Tape & Reel (TR) format, which is standard for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can BFC246707124 be used as a direct replacement for BFC246929124?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 0.12 µF capacitance, ±5% tolerance, 100V DC rating, polyester metallized dielectric, -55°C to 105°C operating range, through-hole radial configuration, and 10.00mm lead spacing. The substitute is currently in active production.

Q: What is the difference in physical dimensions between these parts?

A: The seated height differs by 2.50mm. The BFC246929124 has a maximum seated height of 0.728" (18.50mm), while the BFC246707124 measures 0.630" (16.00mm). All other dimensions, including length, width, and lead spacing, are identical. This height difference may be beneficial in applications with vertical space constraints.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant. The substitute part includes REACH Unaffected status in its documentation. No compliance barriers exist for substitution.

Q: What packaging formats are available?

A: The BFC246929124 is supplied in standard packaging. The BFC246707124 is available in Tape & Reel (TR) format, which is optimized for automated pick-and-place assembly. Tape & Reel packaging does not affect component performance or electrical characteristics.

Q: Why is the original part listed as obsolete?

A: The BFC246929124 (MKT469 series) has been superseded by the BFC246707124 (MKT467 series) within Vishay's product portfolio. The substitute maintains full electrical and mechanical compatibility while offering active production status and improved availability.
