• Tolerance: ±5% (exact match required)
• Voltage rating: 250V DC minimum / 160V AC minimum
• Dielectric material: Polyester, Metallized (exact match required)
• Operating temperature range: -55°C to 105°C minimum (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)
• Physical dimensions: 10.00mm x 4.00mm with 5.00mm lead spacing (exact match required)
• Termination: PC Pins (exact match required)

The BFC236642333 meets all substitution criteria as an active product alternative within the same manufacturer family.

Parameter Comparison

Engineering Selection Recommendations

The BFC236642333 is the primary substitute for the obsolete BFC236542333. Both components are manufactured by Vishay Beyschlag/Draloric/BC Components and maintain identical electrical specifications and physical form factors.

The BFC236642333 carries active product status, ensuring ongoing availability and supply chain support. Both parts maintain ROHS3 compliance, satisfying regulatory requirements for current manufacturing environments.

The transition from MKT365 series to MKT366 series represents a product line evolution within the same manufacturer. Electrical performance and mechanical compatibility remain unchanged, enabling direct substitution in existing circuit designs without modification to PCB layouts or component footprints.

Frequently Asked Questions (FAQ)

Q: Can BFC236642333 replace BFC236542333 in existing designs?

A: Yes. The BFC236642333 provides direct electrical and mechanical equivalence. All critical parameters—capacitance, voltage rating, tolerance, dielectric material, operating temperature range, and physical dimensions—are identical. No circuit redesign or PCB modification is required.

Q: What is the difference between MKT365 and MKT366 series?

A: Both series are polyester metallized film capacitor lines from Vishay. The MKT365 series (BFC236542333) is obsolete, while the MKT366 series (BFC236642333) is active. The electrical and mechanical specifications remain equivalent across both series for this capacitance value and voltage rating.

Q: Are there packaging differences between the main part and substitute?

A: The BFC236542333 is supplied in standard packaging, while the BFC236642333 is available in Tape & Reel (TR) format. Both maintain identical component dimensions and lead spacing. Tape & Reel packaging is standard for active production components and does not affect electrical performance or PCB assembly compatibility.

Q: Do both parts meet current compliance standards?

A: Yes. Both the BFC236542333 and BFC236642333 are ROHS3 compliant. The BFC236642333 additionally carries REACH Unaffected status, confirming compliance with current environmental regulations.

Q: What applications are these capacitors suitable for?

A: Both components are rated for general-purpose applications. The 0.033 µF capacitance, 250V DC rating, and polyester dielectric make them suitable for filtering, coupling, and decoupling functions in industrial and consumer electronics operating across the -55°C to 105°C temperature range.
