Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC230348474 is determined by the following critical parameters:

• Capacitance value must remain 0.47 µF
• DC voltage rating must be equal to or greater than 250V
• Dielectric material must be polyester, metallized construction
• Mounting type must be through-hole radial configuration
• Operating temperature range must encompass -55°C ~ 105°C
• Termination must be PC pins
• RoHS3 compliance is required for regulatory alignment

The BFC237348474 meets all substitution criteria. While it features improved tolerance (±5% versus ±10%) and higher AC voltage rating (160V versus 63V), these represent enhanced specifications that do not compromise compatibility. The increased physical dimensions and lead spacing reflect the design evolution within the MKT series family.

Parameter Comparison

Engineering Selection Recommendations

The BFC237348474 is the designated manufacturer substitute for the obsolete BFC230348474. Both components maintain identical capacitance, DC voltage rating, dielectric composition, and operating temperature specifications. The substitute carries active product status, ensuring long-term availability and supply chain continuity.

Physical dimension differences require PCB layout verification. The BFC237348474 occupies a larger footprint with increased lead spacing (15.00mm versus 10.00mm). Designs utilizing the original BFC230348474 must confirm that board-level spacing accommodates the substitute's geometry before implementation.

Both parts maintain ROHS3 compliance and MSL Level 1 classification, supporting regulatory requirements and manufacturing processes without additional moisture control measures.

Frequently Asked Questions (FAQ)

Q: Can the BFC237348474 directly replace the BFC230348474 in existing designs?

A: Electrical compatibility is confirmed across all critical parameters. Physical compatibility requires PCB layout verification due to increased component dimensions and lead spacing. The substitute's larger footprint may necessitate board redesign in space-constrained applications.

Q: What is the significance of the tolerance difference between ±10% and ±5%?

A: The BFC237348474 provides tighter capacitance tolerance, representing improved manufacturing precision. This does not affect substitution eligibility but may benefit applications requiring stricter capacitance accuracy.

Q: Why is the AC voltage rating higher on the substitute part?

A: The BFC237348474 (MKT373 series) represents a design evolution with enhanced AC voltage performance. The 250V DC rating remains identical on both parts, which is the primary specification for DC-biased applications.

Q: Are there packaging differences between these parts?

A: The BFC230348474 is supplied in standard packaging, while the BFC237348474 is available in Tape & Reel (TR) format. Both use identical PC pin termination and radial through-hole mounting.

Q: What should be verified before implementing the BFC237348474 as a substitute?

A: Confirm PCB layout accommodates the larger physical dimensions and 15.00mm lead spacing. Verify that the increased component height (18.50mm seated maximum) does not conflict with board assembly constraints or enclosure clearances.
