Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC236545104 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.1 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating: 250V DC minimum, 160V AC minimum
• Dielectric type: Polyester, metallized construction
• Mounting configuration: Through-hole radial with 5.00mm lead spacing
• Termination style: PC pins
• Operating temperature range: -55°C to 105°C minimum

The BFC236645104 qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is product status: BFC236645104 is active production, whereas BFC236545104 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The BFC236645104 is the direct substitute for BFC236545104. Selection is based on the following factors:

• Electrical equivalence: Identical capacitance, tolerance, and voltage ratings ensure functional compatibility in all circuit applications
• Mechanical compatibility: Identical package dimensions, lead spacing, and termination style permit direct board-level substitution without layout modification
• Compliance alignment: Both components maintain ROHS3 compliance and identical tariff classification, supporting regulatory and procurement consistency
• Product availability: BFC236645104 maintains active production status with current inventory, addressing the obsolescence of the original part number

Frequently Asked Questions (FAQ)

Q: Can BFC236645104 be used as a direct replacement for BFC236545104 on existing PCBs?

A: Yes. The components are mechanically and electrically identical. Lead spacing, package dimensions, and all electrical parameters match exactly, permitting direct substitution without PCB modification.

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

A: Both series are polyester metallized film capacitors from Vishay with identical electrical and mechanical specifications for this capacitance value. The series designation reflects internal manufacturing or design revision; functional performance is equivalent.

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

A: No. Both components carry ROHS3 compliance, identical ECCN classification (EAR99), and matching HTSUS codes. Regulatory and export requirements are equivalent.

Q: Does the packaging format affect substitution eligibility?

A: No. The BFC236645104 is supplied in Tape & Box (TB) format, while the original BFC236545104 packaging is not specified. Both formats contain the same component; packaging format does not affect electrical or mechanical compatibility.

Q: What is the lead spacing tolerance, and does it affect PCB compatibility?

A: Lead spacing is 0.197" (5.00mm) for both components. This dimension is fixed and identical between parts, ensuring PCB hole pattern compatibility without adjustment.
