BFC230356154 Equivalent & Substitute Parts

Part Overview

The BFC230356154 is a 0.15 µF film capacitor rated for 400V DC operation, manufactured by Vishay Beyschlag/Draloric/BC Components as part of the MKT303 series. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The radial through-hole configuration and polyester metallized dielectric make this capacitor suitable for general-purpose applications requiring stable capacitance and long operational life across the -55°C to 105°C temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC230356154 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must be 0.15 µF (no tolerance deviation permitted)
• Tolerance: Must be ±5% or tighter
• DC Voltage Rating: Must be 400V or higher
• Dielectric Type: Must be polyester, metallized construction
• Operating Temperature Range: Must support -55°C to 105°C minimum
• Mounting Configuration: Must be through-hole radial with PC pin termination
• Compliance: Must maintain ROHS3 compliance status

The substitute part BFC237356154 meets all these criteria while offering improved product status (active vs. obsolete) and enhanced AC voltage rating capability.

Parameter Comparison

Engineering Selection Recommendations

The BFC237356154 serves as a direct functional substitute for the obsolete BFC230356154. Both components maintain identical capacitance, tolerance, and DC voltage specifications. The substitute part offers the advantage of active product status, ensuring continued availability and manufacturing support. Both parts maintain ROHS3 compliance and equivalent thermal operating ranges.

Physical dimensions differ between the two parts. The BFC237356154 is larger with increased lead spacing (15.00mm vs. 10.00mm), requiring PCB layout verification to confirm mechanical compatibility. The substitute part's enhanced AC voltage rating (220V vs. 100V) provides additional operational margin in AC applications without affecting DC circuit performance.

Frequently Asked Questions (FAQ)

Q: Can BFC237356154 replace BFC230356154 in all applications?

A: Electrical substitution is valid for all DC applications where the 400V rating is required. Physical board layout must be verified due to increased component dimensions and lead spacing. The larger footprint may require PCB redesign in space-constrained applications.

Q: What is the significance of the different AC voltage ratings?

A: The AC voltage rating indicates the maximum AC voltage the capacitor can withstand. The substitute part's 220V AC rating (vs. 100V AC) provides greater margin in mixed AC/DC or AC-coupled circuits. This does not affect DC-only circuit performance.

Q: Are both parts RoHS compliant?

A: Yes, both BFC230356154 and BFC237356154 are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the impact of different lead spacing on circuit design?

A: Lead spacing increases from 10.00mm to 15.00mm. PCB hole patterns must be modified to accommodate the wider spacing. Existing through-hole patterns cannot be reused without layout modification.

Q: Why is the substitute part larger?

A: The BFC237356154 belongs to the MKT373 series, which uses a different physical package design than the MKT303 series. The larger envelope accommodates the enhanced AC voltage rating and improved thermal characteristics while maintaining the same capacitance value.
