Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC237590429 is determined by the following criteria:

• Capacitance value must match exactly: 0.015 µF
• Tolerance must be equivalent or tighter: ±5% or better
• Voltage rating must meet or exceed the application requirement: minimum 1000V DC
• Dielectric material must be polypropylene (PP), metallized
• Operating temperature range must encompass or match: -55°C ~ 105°C
• Mounting type must be through hole with radial configuration
• Lead spacing must be compatible: 0.591" (15.00mm)
• Termination must be PC pins
• RoHS3 compliance is required

The PHE426SB5150JR06 from KEMET meets all substitution criteria with a higher voltage rating (2000V DC) and equivalent mechanical and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The PHE426SB5150JR06 is a direct substitute for the BFC237590429 based on matching electrical and mechanical specifications. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The KEMET part provides a higher voltage rating (2000V DC versus 1000V DC), which offers additional design margin in applications operating at or near the original 1000V specification. Both parts maintain identical capacitance, tolerance, temperature range, and lead spacing, ensuring functional equivalence in through-hole PCB applications. Selection between these parts should be based on availability, cost, and specific application voltage requirements.

Frequently Asked Questions (FAQ)

Q: Can the PHE426SB5150JR06 be used as a direct replacement for the BFC237590429?

A: Yes. Both parts share identical capacitance (0.015 µF), tolerance (±5%), operating temperature range (-55°C ~ 105°C), lead spacing (15.00mm), and termination type (PC pins). The KEMET part has a higher voltage rating, which is compatible with applications designed for the original 1000V specification.

Q: What is the physical size difference between these parts?

A: The BFC237590429 measures 0.728" L × 0.335" W with a maximum seated height of 0.807". The PHE426SB5150JR06 measures 0.709" L × 0.335" W with a maximum seated height of 0.630". Both fit the same 15.00mm lead spacing, though the KEMET part is slightly more compact.

Q: Are both parts suitable for high pulse and DV/DT applications?

A: The BFC237590429 is specified for high pulse and DV/DT applications. The PHE426SB5150JR06 is specified for DC link, DC filtering, high frequency, switching, and high pulse DV/DT applications, making it suitable for the same high pulse requirements.

Q: Do both parts meet current compliance standards?

A: Yes. Both the BFC237590429 and PHE426SB5150JR06 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What determines whether a substitute part is acceptable?

A: Substitution is based on matching capacitance value, tolerance, minimum voltage rating, dielectric material, operating temperature range, mounting type, lead spacing, termination style, and compliance certifications. The substitute must meet or exceed all electrical and mechanical requirements of the original part.
