• Voltage rating (DC): 250V (minimum requirement)
• Voltage rating (AC): 160V (minimum requirement)
• Dielectric material: Polyester, Metallized (exact match)
• Operating temperature range: -55°C to 105°C (minimum requirement)

Mechanical Equivalence Requirements:

• Mounting type: Through Hole (exact match)
• Package type: Radial (exact match)
• Physical dimensions: 10.00mm L × 5.50mm W (exact match)
• Height (seated): 15.50mm maximum (exact match)
• Lead spacing: 5.00mm (exact match)
• Termination: PC Pins (exact match)

Compliance Requirements:

• RoHS3 compliance (mandatory for modern applications)

The BFC236646154 meets all substitution criteria and is classified as an active, manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The BFC236646154 is the manufacturer-recommended substitute for the obsolete BFC236546154. Both components are manufactured by Vishay Beyschlag/Draloric/BC Components and maintain identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can the BFC236646154 be used as a direct replacement for the BFC236546154 in existing designs?

A: Yes. The BFC236646154 is electrically and mechanically identical to the BFC236546154. All electrical parameters, physical dimensions, lead spacing, and mounting characteristics are equivalent. No circuit modifications or PCB layout changes are required.

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

A: The MKT365 series (BFC236546154) is obsolete. The MKT366 series (BFC236646154) is the current active product line from the manufacturer. Both series maintain identical specifications for this capacitance and voltage rating.

Q: Are there packaging differences between these parts?

A: The BFC236546154 packaging information was not specified in the original documentation. The BFC236646154 is supplied in Tape & Box (TB) packaging, which is standard for through-hole radial film capacitors in production environments.

Q: Does the BFC236646154 meet RoHS compliance requirements?

A: Yes. The BFC236646154 is ROHS3 compliant, meeting current environmental and regulatory standards for electronic components.

Q: What is the lead spacing for these radial capacitors?

A: Both the BFC236546154 and BFC236646154 have a lead spacing of 5.00mm (0.197 inches), which is the standard pitch for radial film capacitors in this size class.

Q: Can these capacitors be used in AC applications?

A: Yes. Both components are rated for 160V AC operation, in addition to their 250V DC rating. The AC rating is the limiting factor for AC-only applications.
