Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC238320474 is determined by the following critical parameters:

• Capacitance value must match exactly at 0.47 µF
• Tolerance must be ±5% or tighter
• Dielectric material must be polypropylene (PP), metallized
• Mounting type must be through-hole radial configuration
• Lead spacing must be 1.083" (27.50mm) to ensure PCB compatibility
• Voltage rating may be equal to or higher than 630V DC without functional degradation
• Operating temperature range must encompass or exceed -55°C to 105°C
• Termination must be PC pins for soldering compatibility
• RoHS3 compliance is required for regulatory alignment

The B32654A0474J000 qualifies as a direct substitute based on these criteria, offering enhanced voltage rating (1000V DC) while maintaining all other core specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the BFC238320474 and B32654A0474J000 maintain Active product status and full ROHS3 compliance, ensuring long-term availability and regulatory conformance. The B32654A0474J000 provides a voltage rating upgrade from 630V to 1000V DC while preserving identical capacitance, tolerance, and lead spacing specifications. This substitute is suitable for applications requiring higher voltage margin or operating in elevated voltage environments. The slight reduction in maximum operating temperature (100°C vs. 105°C) is negligible for most industrial applications. Both components are certified for high-pulse and DV/DT applications, with the substitute offering AEC-Q200 automotive qualification. Selection between these parts should be based on specific circuit voltage requirements and application environment specifications.

Frequently Asked Questions (FAQ)

Q: Can the B32654A0474J000 be used as a direct replacement for the BFC238320474?

A: Yes, the B32654A0474J000 is electrically and mechanically compatible. Both components share identical capacitance (0.47 µF), tolerance (±5%), lead spacing (27.50mm), and termination type (PC pins). The substitute offers higher voltage rating (1000V vs. 630V DC), making it suitable for applications requiring additional voltage margin.

Q: What are the physical dimension differences between these parts?

A: The BFC238320474 measures 1.220" L × 0.512" W with a maximum seated height of 0.906". The B32654A0474J000 measures 1.240" L × 0.551" W with a maximum seated height of 0.965". These minor dimensional variations remain within typical PCB layout tolerances for radial through-hole components with 27.50mm lead spacing.

Q: Are both parts suitable for high-pulse applications?

A: Yes, both the BFC238320474 and B32654A0474J000 are specified for high-pulse and DV/DT applications. The metallized polypropylene dielectric in both components provides the low ESR and stable performance required for these demanding operating conditions.

Q: What is the significance of the AEC-Q200 rating on the substitute part?

A: AEC-Q200 certification indicates the B32654A0474J000 meets automotive-grade reliability standards. This qualification is not present on the BFC238320474 but does not preclude use of either part in non-automotive applications.

Q: How do the operating temperature ranges compare?

A: The BFC238320474 operates from -55°C to 105°C, while the B32654A0474J000 operates from -55°C to 100°C. Both ranges cover standard industrial and commercial temperature environments. The 5°C difference at the upper limit is not significant for most applications.

Q: Are both parts RoHS compliant?

A: Yes, both the BFC238320474 and B32654A0474J000 are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
