Substitute Part Grouping Explanation

Substitution of the BFC230342564 is based on electrical and mechanical parameter equivalence within the film capacitor category. The following criteria determine valid substitutes:

Electrical Equivalence Requirements:

• Capacitance value: 0.56 µF (exact match)
• Tolerance: ±5% (matching specification)
• Voltage rating: 250V DC minimum (equal or higher acceptable)
• Dielectric material: Polyester, Metallized (same material system)
• Temperature range: -55°C to 105°C (equal or wider range acceptable)

Mechanical Compatibility Requirements:

• Mounting type: Through Hole (radial configuration)
• Lead spacing: 0.394" (10.00mm) (exact match for PCB compatibility)
• Termination: PC Pins (standard radial lead format)
• Package classification: Radial (form factor match)

The BFC2373EF564MD qualifies as a direct substitute, meeting all electrical and mechanical parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The BFC2373EF564MD is the qualified substitute for the obsolete BFC230342564. Both components are manufactured by Vishay Beyschlag/Draloric/BC Components and maintain identical electrical specifications across capacitance, tolerance, voltage rating, and temperature operating range. Both parts are ROHS3 compliant with MSL rating of 1, ensuring compatibility with standard manufacturing and storage protocols.

The primary distinction is product status: the BFC230342564 is obsolete while the BFC2373EF564MD is active, providing assured long-term availability and supply chain continuity. The substitute exhibits minor dimensional variations in width (0.236" versus 0.228") and seated height (0.472" versus 0.413"), which remain within typical PCB layout tolerances for radial through-hole components. Lead spacing remains identical at 0.394" (10.00mm), ensuring direct PCB footprint compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the BFC2373EF564MD be used as a direct replacement for the BFC230342564 on existing PCBs?

A: Yes. Both components share identical lead spacing (0.394" / 10.00mm), termination type (PC Pins), and mounting configuration (radial through-hole). The minor dimensional differences in body width and height do not affect electrical performance or mechanical fit on standard PCB layouts designed for radial film capacitors.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Capacitance (0.56 µF), tolerance (±5%), voltage ratings (250V DC / 63V AC), dielectric material (polyester metallized), and operating temperature range (-55°C to 105°C) are identical across both components.

Q: What is the significance of the product status difference?

A: The BFC230342564 is classified as obsolete, indicating discontinued manufacturing and limited remaining inventory. The BFC2373EF564MD is active, ensuring ongoing production, established supply channels, and long-term component availability for new designs and production runs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the BFC230342564 and BFC2373EF564MD are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level), meeting current environmental and manufacturing standards.

Q: Are there any circuit design considerations when substituting these components?

A: No design modifications are required. The electrical parameters are equivalent, and the components are functionally interchangeable within circuits designed for 0.56 µF, 250V DC polyester film capacitors.
