Key Parameters

Substitute Part Grouping Explanation

Substitution of BFC230366274 is determined by the following critical parameters that must remain constant or compatible:

• Capacitance Value: 0.27 µF (exact match required)
• Tolerance: ±5% (exact match required)
• DC Voltage Rating: 630V (minimum requirement; higher ratings acceptable)
• Dielectric Type: Polyester, Metallized (material class must match)
• Mounting Configuration: Through Hole Radial (physical interface requirement)
• Termination Style: PC Pins (PCB connection compatibility)
• Operating Temperature Range: -55°C ~ 105°C (functional envelope)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The substitute part BFC237364274 satisfies all critical substitution criteria while maintaining functional equivalence. Physical dimensions and lead spacing differ between the main part and substitute, requiring PCB layout verification during implementation.

Parameter Comparison

Engineering Selection Recommendations

BFC237364274 is the qualified substitute for BFC230366274 based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical capacitance (0.27 µF), tolerance (±5%), and DC voltage rating (630V). The substitute exhibits a higher AC voltage rating (250V versus 160V), which provides additional operational margin without compromising circuit function.

Material and Thermal Compatibility: Polyester metallized dielectric construction and operating temperature range (-55°C ~ 105°C) are identical, ensuring equivalent performance across the specified thermal envelope.

Regulatory Compliance: Both parts are ROHS3 compliant, satisfying current environmental and regulatory requirements for component procurement and deployment.

Product Status: The substitute part (BFC237364274) carries active product status from the manufacturer, ensuring ongoing availability and supply chain continuity. The main part (BFC230366274) is obsolete, making the substitute the appropriate selection for new designs and ongoing production requirements.

Physical Integration Consideration: The substitute part exhibits larger physical dimensions (26.00mm length versus 17.50mm, 18.00mm height versus 13.10mm) and wider lead spacing (22.50mm versus 15.00mm). PCB layout modifications are required to accommodate these dimensional differences.

Frequently Asked Questions (FAQ)

Q: Can BFC237364274 be used as a direct replacement for BFC230366274 without circuit modification?

A: Electrical substitution is valid. The capacitance, tolerance, voltage rating, dielectric material, and operating temperature range are identical. However, physical dimensions and lead spacing differ, requiring PCB layout adjustment to accommodate the larger footprint and wider lead spacing of the substitute part.

Q: What is the significance of the different AC voltage ratings (160V versus 250V)?

A: Both parts are rated for 630V DC operation. The AC voltage rating difference reflects different design margins within each series. The substitute's higher AC rating (250V) provides additional operational headroom and does not restrict substitution in applications designed for the original part's 160V AC rating.

Q: Are both parts suitable for the same temperature range applications?

A: Yes. Both BFC230366274 and BFC237364274 operate across the identical temperature range of -55°C to 105°C, ensuring thermal compatibility in equivalent applications.

Q: Why is the substitute part physically larger?

A: BFC237364274 belongs to the MKT373 series, while the original part belongs to the MKT303 series. Different series designations reflect different design generations and construction approaches within Vishay's film capacitor portfolio. The larger dimensions of the MKT373 series do not indicate superior performance but rather represent a different design iteration.

Q: Is RoHS compliance maintained with the substitute part?

A: Yes. Both parts are ROHS3 compliant, maintaining regulatory compliance for procurement and deployment in regulated markets and applications.

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

A: PCB layout compatibility must be confirmed. The substitute part's larger dimensions (26.00mm length, 18.00mm height) and wider lead spacing (22.50mm) require verification that the PCB footprint can accommodate these physical parameters without design conflicts or clearance violations.
