BFC246965333 Equivalent & Substitute Parts

Part Overview

The BFC246965333 is a 0.033 µF film capacitor manufactured by Vishay Beyschlag/Draloric/BC Components, rated for 630V DC operation with polyester metallized dielectric construction. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and design continuity. The MKT469 series designation identifies this specific product line. Substitute parts must maintain electrical performance across voltage, capacitance, tolerance, and thermal operating ranges while accommodating mechanical form factor variations.

Substitute Part Grouping Explanation

Substitution of the BFC246965333 is based on strict equivalence across the following critical parameters:

Capacitance value: 0.033 µF (exact match required)
Tolerance: ±10% (exact match required)
Voltage rating: 630V DC minimum, 250V AC minimum
Dielectric type: Polyester, metallized construction
Operating temperature range: -55°C to +105°C minimum
Mounting configuration: Through-hole radial package
Lead spacing: 0.394 inches (10.00 mm)
Termination style: PC pins

The BFC246740333 qualifies as a direct substitute based on matching all electrical specifications and core mechanical parameters. Both components are manufactured by Vishay Beyschlag/Draloric/BC Components and share identical capacitance, voltage ratings, dielectric material, temperature range, and lead spacing. The primary distinction is series designation (MKT467 versus MKT469) and physical height variation, which does not affect electrical performance or PCB compatibility in standard through-hole applications.

Engineering Selection Recommendations

The BFC246740333 is the qualified substitute for the obsolete BFC246965333 based on the following engineering criteria:

Electrical Equivalence: Both components deliver identical capacitance (0.033 µF), tolerance (±10%), and voltage ratings (630V DC, 250V AC). The polyester metallized dielectric construction ensures equivalent performance across the full operating temperature range (-55°C to +105°C).

Mechanical Compatibility: Lead spacing (0.394 inches / 10.00 mm) and through-hole radial configuration are identical, ensuring direct PCB footprint compatibility. The height variation (0.508" to 0.626") does not affect electrical function or standard board layout applications.

Compliance Status: Both components are ROHS3 compliant. The BFC246740333 carries active product status with confirmed inventory availability (1122 pcs), ensuring long-term procurement viability compared to the obsolete BFC246965333.

Series Transition: The shift from MKT469 to MKT467 series reflects Vishay's product line consolidation. Both series employ identical electrical specifications and construction methods, confirming functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can BFC246740333 replace BFC246965333 in existing designs?

A: Yes. The BFC246740333 is electrically and mechanically equivalent. Capacitance, voltage ratings, tolerance, dielectric material, operating temperature range, lead spacing, and termination style are identical. The height difference (3.00 mm) does not affect standard through-hole PCB applications.

Q: What is the significance of the series change from MKT469 to MKT467?

A: Series designation reflects Vishay's internal product categorization. Both MKT469 and MKT467 employ identical polyester metallized dielectric technology and electrical specifications. The change represents product line consolidation, not a functional modification.

Q: Are there any compliance differences between the two parts?

A: Both components are ROHS3 compliant. The BFC246740333 includes REACH Unaffected status documentation. No compliance barriers exist for substitution.

Q: Why is the BFC246965333 obsolete?

A: Obsolescence reflects Vishay's product portfolio rationalization. The BFC246740333 provides equivalent performance with active manufacturing status and improved supply chain availability.

Q: Does the height variation affect PCB layout?

A: The 3.00 mm height increase (0.508" to 0.626") does not impact standard through-hole board designs. Verify clearance in applications with height-constrained enclosures or dense component placement.

Q: What inventory status should be considered for procurement?

A: The BFC246740333 maintains active production with 1122 pcs in stock, ensuring reliable long-term availability. The BFC246965333 is obsolete with limited remaining inventory (1006 pcs).
