Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC230343155 is determined by the following critical parameters:

• Capacitance Value: Must be 1.5 µF (exact match required)
• Tolerance: Must be ±10% or tighter
• DC Voltage Rating: Must be 250V or higher
• AC Voltage Rating: Must be 63V or higher
• Dielectric Type: Must be polyester metallized film
• Mounting Configuration: Must be through-hole radial
• Termination Style: Must be PC pins
• Temperature Range: Must support -55°C to 105°C operation
• Compliance: Must maintain ROHS3 compliance

The BFC237341155 meets all substitution criteria as an active-status alternative within the same manufacturer's product portfolio.

Parameter Comparison

Engineering Selection Recommendations

The BFC237341155 is a direct functional equivalent for the obsolete BFC230343155. Both components share identical capacitance, tolerance, DC voltage rating, dielectric composition, temperature range, and mounting configuration. The substitute part maintains ROHS3 compliance and carries active product status, ensuring ongoing availability and supply chain support.

The BFC237341155 provides enhanced AC voltage rating (160V versus 63V), representing an improvement in performance margin without compromising any electrical or mechanical compatibility requirements. Physical dimensions differ between the two series, with the MKT373 package being larger; PCB layout modifications may be necessary to accommodate the increased footprint.

Frequently Asked Questions (FAQ)

Q: Can the BFC237341155 be used as a direct replacement for the BFC230343155?

A: Yes. Both parts share identical capacitance (1.5 µF), tolerance (±10%), DC voltage rating (250V), dielectric material (polyester metallized), operating temperature range (-55°C to 105°C), mounting type (through-hole radial), and termination style (PC pins). The substitute part is active-status and ROHS3 compliant.

Q: What are the physical differences between these parts?

A: The BFC230343155 measures 0.689" L × 0.287" W with 0.591" lead spacing. The BFC237341155 measures 1.024" L × 0.335" W with 0.886" lead spacing. PCB layout adjustments are required to accommodate the larger MKT373 package footprint.

Q: Does the higher AC voltage rating of the substitute part affect compatibility?

A: No. The BFC237341155 AC rating of 160V exceeds the original 63V specification, providing additional performance margin. This represents an improvement and does not create compatibility issues.

Q: Are both parts RoHS compliant?

A: Yes. Both the BFC230343155 and BFC237341155 are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level).

Q: Why is the original part obsolete?

A: The BFC230343155 carries obsolete status. The BFC237341155 from the newer MKT373 series provides equivalent electrical performance with active product status and assured long-term availability.
