BFC230348564 Equivalent & Substitute Parts

Part Overview

The BFC230348564 is a 0.56 µF film capacitor rated for 250V DC operation with ±10% tolerance, manufactured by Vishay Beyschlag/Draloric/BC Components as part of the MKT303 series. This component is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement continuity. The radial through-hole configuration and polyester metallized dielectric make it suitable for general-purpose applications requiring stable capacitance across the specified temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC230348564 is based on the following critical parameters that must remain constant or be exceeded:

• Capacitance value: 0.56 µF (exact match required)
• Voltage rating - DC: 250V minimum (equal or higher acceptable)
• Dielectric material: Polyester, Metallized (same material family)
• Mounting type: Through Hole Radial (same form factor)
• Operating temperature range: -55°C to 105°C (same or wider range acceptable)
• RoHS compliance: ROHS3 Compliant (regulatory requirement maintained)

The BFC237348564 qualifies as a direct substitute based on these parameters. While it features improved tolerance (±5% versus ±10%) and higher AC voltage rating (160V versus 63V), these represent enhancements that do not compromise compatibility. Physical dimensions differ due to the tighter tolerance specification, requiring verification of board layout clearance.

Parameter Comparison

Engineering Selection Recommendations

The BFC237348564 is the recommended substitute for the obsolete BFC230348564. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility. The substitute part is currently in active production status, providing supply chain continuity.

The primary consideration for implementation is physical board layout. The BFC237348564 has larger dimensions and increased lead spacing (15.00mm versus 10.00mm), requiring verification that the PCB footprint accommodates the larger component. The improved tolerance specification (±5% versus ±10%) provides tighter capacitance control, which may benefit circuit performance in applications sensitive to capacitance variation.

Frequently Asked Questions (FAQ)

Q: Can the BFC237348564 be used as a direct pin-for-pin replacement?

A: No. While both components are radial through-hole capacitors with identical capacitance and DC voltage ratings, the lead spacing differs (15.00mm versus 10.00mm). PCB modification or adapter solutions may be required. Physical dimensions must be verified against available board space.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), tolerance specification (±10% versus ±5%), AC voltage rating (63V versus 160V), and physical dimensions. The capacitance value, DC voltage rating, dielectric material, and operating temperature range remain identical.

Q: Is the improved tolerance of the BFC237348564 beneficial?

A: The ±5% tolerance provides tighter capacitance control compared to the ±10% specification of the original part. This may improve circuit performance in applications where capacitance precision affects frequency response, filtering characteristics, or timing functions. Evaluation depends on specific circuit requirements.

Q: Are there any compliance or certification concerns with substitution?

A: Both parts maintain ROHS3 compliance and identical moisture sensitivity levels. No compliance barriers exist for substitution from a regulatory perspective.

Q: What should be verified before implementing the substitute part?

A: Verify PCB footprint compatibility with the larger lead spacing (15.00mm) and increased physical dimensions. Confirm that circuit performance tolerates the improved tolerance specification. Validate that the higher AC voltage rating (160V) does not introduce unintended circuit behavior changes.
