BFC230352124 Equivalent & Substitute Parts

Part Overview

The BFC230352124 is a 0.12 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 BFC230352124 is determined by the following critical parameters:

• Capacitance Value: Must be 0.12 µF (exact match required)
• Tolerance: ±5% (matching tolerance specification)
• Voltage Rating - DC: Minimum 400V (equal or higher acceptable)
• Dielectric Material: Polyester, Metallized (maintains electrical characteristics)
• Mounting Type: Through Hole (maintains PCB assembly compatibility)
• Package / Case: Radial (maintains form factor and lead configuration)
• Termination: PC Pins (maintains soldering compatibility)
• Operating Temperature Range: -55°C ~ 105°C (minimum requirement)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The BFC237352124 qualifies as a direct substitute based on matching all critical parameters while maintaining equivalent electrical performance and physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The BFC237352124 is a qualified substitute for the BFC230352124 based on the following engineering criteria:

• Electrical Equivalence: Both parts maintain identical capacitance (0.12 µF), tolerance (±5%), and DC voltage rating (400V), ensuring functional compatibility in circuit applications.
• Regulatory Compliance: Both parts are ROHS3 compliant, meeting current environmental and regulatory requirements.
• Product Status: The BFC237352124 is active in production, providing supply continuity for the obsolete BFC230352124.
• Physical Compatibility: While the substitute exhibits larger physical dimensions and increased lead spacing, both maintain radial through-hole configuration with PC pin termination, compatible with standard PCB assembly processes.

Selection of the BFC237352124 requires verification that the increased component footprint (17.50mm x 6.00mm versus 12.50mm x 4.30mm) and lead spacing (15.00mm versus 10.00mm) accommodate the available PCB layout space.

Frequently Asked Questions (FAQ)

Q: Can the BFC237352124 be used as a direct replacement for the BFC230352124?

A: Yes, the BFC237352124 qualifies as a substitute based on matching capacitance, tolerance, DC voltage rating, dielectric material, mounting type, and operating temperature range. Physical dimensions differ; PCB layout compatibility must be confirmed.

Q: What is the primary difference between these two parts?

A: The main differences are physical size and lead spacing. The BFC237352124 (MKT373 series) is larger (17.50mm x 6.00mm with 15.00mm lead spacing) compared to the BFC230352124 (MKT303 series, 12.50mm x 4.30mm with 10.00mm lead spacing). AC voltage rating also differs (220V versus 100V), though DC ratings remain identical at 400V.

Q: Are there any compatibility concerns with PCB assembly?

A: The increased lead spacing of the BFC237352124 (15.00mm) requires PCB pad spacing compatible with this dimension. Standard through-hole assembly processes remain applicable for both parts.

Q: Why is the BFC230352124 listed as obsolete?

A: Obsolescence indicates the part is no longer in active production. The BFC237352124, as an active production part from the same manufacturer with equivalent electrical specifications, provides supply continuity.

Q: Do both parts meet current regulatory requirements?

A: Yes, both the BFC230352124 and BFC237352124 are ROHS3 compliant, meeting current environmental and regulatory standards.
