BF024I0223K-- Equivalent & Substitute Parts

Part Overview

The BF024I0223K-- is a 0.022 µF film capacitor manufactured by KYOCERA AVX, rated for 400V DC operation with polyester metallized dielectric construction. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The radial through-hole configuration and ±10% tolerance make this part suitable for general-purpose applications requiring stable capacitance across temperature ranges from -55°C to 100°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BF024I0223K-- is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.022 µF (exact match required)
• Tolerance: ±10% (maintains circuit design specifications)
• Voltage Rating (DC): 400V minimum (ensures safe operation margin)
• Dielectric Type: Polyester, Metallized (electrical performance characteristics)
• Mounting Configuration: Through Hole, Radial (PCB compatibility)
• Lead Spacing: 0.200" (5.08mm) (footprint compatibility)

The substitute part BFC237051223 meets all these criteria, providing functional equivalence for direct replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The BFC237051223 serves as the direct equivalent substitute for the obsolete BF024I0223K--. Selection of this alternative is supported by:

• Electrical Equivalence: Identical capacitance, tolerance, and DC voltage rating ensure circuit performance parity
• Physical Compatibility: Matching lead spacing (0.200") and radial through-hole configuration enable direct PCB footprint compatibility
• Active Product Status: BFC237051223 maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Enhanced Compliance: ROHS3 compliance of the substitute part addresses modern regulatory requirements, whereas the original part carries non-compliant status
• Extended Temperature Range: Operating range of -55°C to 105°C provides additional thermal margin compared to the original -55°C to 100°C specification

Frequently Asked Questions (FAQ)

Q: Can BFC237051223 be used as a direct replacement for BF024I0223K-- without circuit modification?

A: Yes. Both parts share identical capacitance (0.022 µF), tolerance (±10%), DC voltage rating (400V), dielectric material (polyester metallized), lead spacing (0.200"), and mounting configuration (through-hole radial). PCB footprint and electrical performance remain unchanged.

Q: What is the significance of the different AC voltage ratings (200V vs. 220V)?

A: The AC voltage rating difference does not affect DC circuit applications. For AC applications, the BFC237051223 provides a 10% higher AC rating (220V vs. 200V), representing an operational advantage with no compatibility concerns.

Q: Does the extended operating temperature range of BFC237051223 (-55°C to 105°C vs. -55°C to 100°C) impact substitution suitability?

A: The extended upper temperature limit of BFC237051223 provides additional thermal margin and does not create compatibility issues. Applications operating within the original -55°C to 100°C range remain fully supported.

Q: Why is RoHS compliance status different between the two parts?

A: The BF024I0223K-- predates modern RoHS regulations and carries non-compliant status. The BFC237051223, as an active product, incorporates ROHS3 compliance, meeting current environmental and regulatory standards. This represents an improvement for new designs and procurement cycles.

Q: Are there any dimensional differences that affect PCB layout?

A: Physical dimensions differ slightly (BF024I0223K--: 7.50mm L × 3.20mm W; BFC237051223: 7.20mm L × 4.50mm W), but lead spacing remains identical at 0.200" (5.08mm). The substitute part is slightly narrower and taller. Verify PCB clearance around the component footprint for height-constrained applications.

Q: What inventory status should be considered for procurement planning?

A: BF024I0223K-- shows 906 units in stock (obsolete status). BFC237051223 shows 827 units in stock (active status). For long-term supply assurance, the active substitute part is recommended for new designs and ongoing procurement.
