Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BF024I0123J-- is determined by the following critical parameters:

• Capacitance Value: Must be 0.012 µF (exact match required)
• Voltage Rating - DC: Must be ≥400V
• Dielectric Type: Polyester, Metallized (maintains electrical performance characteristics)
• Mounting Configuration: Through Hole, Radial package with 0.200" (5.08mm) lead spacing (ensures mechanical compatibility with existing PCB layouts)
• Termination Style: PC Pins (direct replacement capability)

The BFC237051123 from Vishay Beyschlag/Draloric/BC Components satisfies all substitution criteria. While tolerance is relaxed to ±10% and operating temperature range extends to 105°C, these parameters remain within acceptable substitution boundaries for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

The BFC237051123 is the qualified substitute for the obsolete BF024I0123J--. Selection is based on the following factors:

Electrical Compatibility: Both components share identical capacitance (0.012 µF) and DC voltage rating (400V). The substitute's ±10% tolerance is acceptable for general-purpose applications where the original ±5% tolerance is not a critical design constraint.

Mechanical Compatibility: Lead spacing (0.200" / 5.08mm) and maximum seated height (0.315" / 8.00mm) are identical, ensuring direct PCB footprint compatibility without layout modifications.

Product Status and Supply: The BFC237051123 is active in production with confirmed inventory availability (1172 pcs), whereas the BF024I0123J-- is obsolete. This substitution ensures long-term supply chain continuity.

Compliance: The BFC237051123 is ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements. The original part is RoHS non-compliant, making the substitute preferable for new designs or compliance-sensitive applications.

Operating Range: The substitute's extended operating temperature range (-55°C ~ 105°C) provides additional thermal margin compared to the original (-55°C ~ 100°C).

Frequently Asked Questions (FAQ)

Q: Can the BFC237051123 be used as a direct replacement for the BF024I0123J-- without PCB modifications?

A: Yes. Both components have identical lead spacing (0.200" / 5.08mm) and maximum seated height (0.315" / 8.00mm). Physical footprint compatibility is confirmed. No PCB layout changes are required.

Q: What is the impact of the tolerance difference (±5% vs. ±10%)?

A: The BF024I0123J-- offers tighter tolerance (±5%), while the BFC237051123 has relaxed tolerance (±10%). For general-purpose applications, this difference is typically acceptable. Applications requiring strict capacitance tolerance should evaluate circuit-level impact before substitution.

Q: Are there any voltage rating differences?

A: Both components are rated for 400V DC. AC voltage ratings differ slightly (200V vs. 220V), but this does not affect DC circuit operation. The substitute's higher AC rating provides additional margin.

Q: Why is RoHS compliance important for this substitution?

A: The BFC237051123 is ROHS3 compliant, meeting current environmental and regulatory standards. The original BF024I0123J-- is RoHS non-compliant. For new designs, repair programs, or systems subject to regulatory requirements, the compliant substitute is the appropriate choice.

Q: Is the extended operating temperature range of the substitute a concern?

A: No. The BFC237051123 operates from -55°C to 105°C, compared to the original -55°C to 100°C. The extended upper limit provides additional thermal margin and is not a limitation for substitution.

Q: What is the series designation of the substitute part?

A: The BFC237051123 belongs to the MKT370 series from Vishay Beyschlag/Draloric/BC Components. This series is designed for automotive and industrial applications with AEC-Q200 qualification.
