BFC246941473 Equivalent & Substitute Parts

Part Overview

The BFC246941473 is a 0.047 µF film capacitor rated for 250V DC operation, manufactured by Vishay Beyschlag/Draloric/BC Components as part of the MKT469 series. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. The capacitor features polyester metallized dielectric construction with radial through-hole mounting, suitable for general-purpose applications requiring stable capacitance across the -55°C to 105°C operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC246941473 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.047 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage ratings: 250V DC minimum and 160V AC minimum
• Dielectric type: Polyester, metallized construction
• Mounting configuration: Through-hole radial package
• Lead spacing: 0.394" (10.00mm) center-to-center
• Termination style: PC pins for PCB insertion
• Temperature range: -55°C to 105°C minimum coverage
• Compliance: ROHS3 compliant

All identified substitute parts meet these criteria. Physical dimensions (length, width, and seated height) may vary within acceptable PCB layout tolerances, provided lead spacing remains constant.

Parameter Comparison

Engineering Selection Recommendations

BFC246753473 (Vishay MKT467 series) is the primary substitute for the obsolete BFC246941473. Both components are manufactured by Vishay and share identical electrical specifications, capacitance tolerance, voltage ratings, and temperature range. The BFC246753473 carries active product status with current manufacturing support. The primary dimensional difference is seated height (0.555" versus 0.437"), which must be evaluated against PCB layout constraints. This part is suitable for direct replacement in applications where vertical clearance permits the increased height.

160473K250C-F (Cornell Dubilier Electronics, 160 series) provides an alternative from a different manufacturer with identical electrical performance. This component features a lower seated height (0.374") and slightly different length and width dimensions, making it advantageous for space-constrained layouts. The 160473K250C-F maintains full compliance with ROHS3 and REACH requirements. Selection between the Vishay and CDE options depends on PCB layout geometry and supply chain availability.

Both substitute parts are active products with established manufacturing continuity, ensuring long-term component availability for production and field service applications.

Frequently Asked Questions (FAQ)

Q: Can BFC246753473 be used as a direct replacement for BFC246941473?

A: Yes. Both parts share identical electrical specifications: 0.047 µF capacitance, ±10% tolerance, 250V DC rating, 160V AC rating, polyester metallized dielectric, and -55°C to 105°C operating range. Lead spacing (0.394" / 10.00mm) is identical, ensuring PCB footprint compatibility. The primary consideration is seated height: BFC246753473 measures 0.555" compared to 0.437" for the original part. Verify clearance above the component location on the PCB.

Q: What is the difference between BFC246753473 and 160473K250C-F?

A: Both are electrically equivalent with identical capacitance, voltage ratings, tolerance, and temperature range. Differences are dimensional and manufacturer-specific. BFC246753473 (Vishay) has a seated height of 0.555", while 160473K250C-F (Cornell Dubilier) measures 0.374" seated height. The CDE part is shorter, making it preferable for compact layouts. Both maintain ROHS3 compliance and PC pin termination with 0.394" lead spacing.

Q: Are there any compliance or certification differences between these parts?

A: All three parts are ROHS3 compliant. BFC246941473 and 160473K250C-F specify Moisture Sensitivity Level 1 (Unlimited). BFC246753473 lists MSL as Not Applicable. The 160473K250C-F includes explicit REACH Unaffected status, while BFC246753473 does not specify REACH compliance in the provided data. For applications requiring documented REACH compliance, 160473K250C-F is the specified choice.

Q: Can I use these parts interchangeably in my design?

A: Electrical interchangeability is confirmed across all three parts. Mechanical interchangeability depends on PCB layout. Lead spacing (0.394" / 10.00mm) is constant, ensuring hole alignment. Verify that the seated height of your selected substitute does not exceed available vertical clearance. If space above the component is limited, 160473K250C-F (0.374" height) is the optimal choice. If height is not constrained, either substitute is acceptable.

Q: Why is BFC246941473 listed as obsolete?

A: The BFC246941473 (MKT469 series) has been discontinued by Vishay. Active alternatives exist within the same manufacturer's product line (BFC246753473, MKT467 series) and from other qualified manufacturers (160473K250C-F, Cornell Dubilier). Substitution to an active product ensures continued availability for future production runs and field service requirements.
