Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC238501472 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: Must be 4700 pF (no tolerance variation acceptable for direct substitution)
• Tolerance: Must be ±5% or tighter
• Dielectric Material: Must be Polypropylene (PP), Metallized
• Mounting Type: Must be Through Hole
• Package Configuration: Must be Radial with 0.591" (15.00mm) lead spacing
• Termination Style: Must be PC Pins
• Operating Temperature Range: Must support -55°C ~ 110°C minimum
• Voltage Rating - DC: Must meet or exceed 1600V DC
• Voltage Rating - AC: Must meet or exceed 550V AC
• RoHS Compliance: Must maintain ROHS3 Compliant status

The substitute part B32672L8472J000 meets all these criteria with enhanced voltage ratings (2000V DC / 700V AC), making it a direct functional equivalent with superior performance margins.

Parameter Comparison

Engineering Selection Recommendations

The B32672L8472J000 is a qualified substitute for the BFC238501472 based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical capacitance (4700 pF), tolerance (±5%), dielectric material (polypropylene metallized), and operating temperature range (-55°C ~ 110°C). The substitute part exceeds the voltage specifications of the main part, providing 2000V DC and 700V AC ratings compared to the required 1600V DC and 550V AC.

Mechanical Compatibility: Lead spacing (15.00mm) and termination style (PC Pins) are identical, ensuring direct PCB footprint compatibility. Physical dimensions show minor variations: the substitute is 0.020" longer in length and 0.020" shorter in seated height. These dimensional differences remain within typical PCB layout tolerances for radial through-hole components.

Compliance Status: Both parts maintain ROHS3 Compliant certification, ensuring regulatory alignment for applications subject to RoHS directives.

Product Status: Both parts are active in production with confirmed inventory availability (BFC238501472: 1132 units; B32672L8472J000: 8416 units).

Frequently Asked Questions (FAQ)

Q: Can the B32672L8472J000 be used as a direct replacement for the BFC238501472?

A: Yes. The substitute part meets all critical electrical and mechanical parameters. Identical capacitance, tolerance, dielectric material, lead spacing, and termination ensure functional equivalence. The higher voltage ratings provide additional performance margin without affecting circuit operation.

Q: Are there any physical installation concerns with the substitute part?

A: The substitute part is 0.020" longer and 0.020" shorter in seated height compared to the main part. These variations are typical for radial film capacitors and should not impact standard PCB layouts. Verify clearance in confined spaces if the component is positioned near other tall components or enclosure walls.

Q: Do both parts have the same environmental compliance?

A: Yes. Both the BFC238501472 and B32672L8472J000 are ROHS3 Compliant, meeting the same regulatory requirements for hazardous substance restrictions.

Q: What is the lead spacing for both parts?

A: Both parts have a lead spacing of 0.591" (15.00mm), ensuring identical PCB footprint compatibility.

Q: Are there any temperature or frequency limitations when using the substitute?

A: Both parts operate across the same temperature range (-55°C ~ 110°C) and are rated for high-frequency switching and high pulse/DV/DT applications. No additional limitations apply to the substitute part.

Q: Which part should be selected for new designs?

A: Selection depends on supply chain availability and cost considerations. Both parts are active and in stock. The substitute part offers higher voltage ratings, which may provide design margin benefits in applications approaching the 1600V DC specification limit.
