BFC238312683 Equivalent & Substitute Parts

Part Overview

The BFC238312683 is a 0.068 µF film capacitor manufactured by Vishay Beyschlag/Draloric/BC Components, rated for 400V DC operation with polypropylene metallized dielectric. This radial through-hole component is designed for high-pulse and DV/DT applications requiring reliable energy storage and filtering in industrial and electronic equipment. The part maintains Active product status with 1172 units in current inventory.

Substitute parts are identified to provide alternatives when the primary component is unavailable, when higher voltage ratings are required for system margin, or when different packaging or inventory conditions necessitate component replacement while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC238312683 is determined by the following criteria:

• Capacitance value must match exactly at 0.068 µF
• Tolerance must be ±5% or tighter
• Voltage rating must be equal to or greater than 400V DC
• Dielectric material must be polypropylene (PP), metallized
• Mounting type must be through-hole radial configuration
• Lead spacing must be 0.591" (15.00mm) to ensure PCB compatibility
• Termination must be PC pins for soldering compatibility
• RoHS3 compliance required for regulatory alignment

The substitute part B32652A6683J000 meets all substitution criteria with an upgraded voltage rating of 630V DC, providing additional system margin while maintaining identical capacitance, tolerance, dielectric type, and lead spacing.

Parameter Comparison

Engineering Selection Recommendations

Both the BFC238312683 and B32652A6683J000 maintain Active product status with full RoHS3 compliance, ensuring regulatory alignment and long-term availability. The B32652A6683J000 provides a higher voltage rating of 630V DC compared to the 400V DC specification of the main part, offering increased system margin for applications subject to voltage transients or overvoltage conditions.

Physical dimensions differ slightly, with the substitute part measuring 0.709" length versus 0.689" for the main part, and a reduced seated height of 0.433" versus 0.472". These dimensional variations require verification against PCB layout constraints and clearance requirements before implementation.

The substitute part carries AEC-Q200 automotive qualification, indicating suitability for automotive-grade applications where the main part does not carry this designation. Selection between these parts should be based on specific voltage margin requirements, physical space constraints, and application-specific certifications.

Frequently Asked Questions (FAQ)

Q: Can B32652A6683J000 be used as a direct replacement for BFC238312683?

A: B32652A6683J000 is functionally equivalent for applications requiring 0.068 µF capacitance at 400V DC or lower. The higher 630V rating of the substitute part is compatible with circuits designed for 400V operation. However, the 0.02" increase in length and 0.039" reduction in seated height require PCB layout verification to ensure adequate clearance and component fit.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching capacitance (0.068 µF), tolerance (±5%), dielectric type (polypropylene metallized), mounting configuration (through-hole radial), lead spacing (0.591"), and termination type (PC pins). Voltage rating of the substitute must equal or exceed 400V DC. Physical dimensions must be verified against PCB constraints.

Q: Are there temperature range differences between these parts?

A: The main part operates from -55°C to 105°C, while the substitute operates from -55°C to 100°C. For applications requiring operation above 100°C, the BFC238312683 is the appropriate selection.

Q: What packaging differences exist between these parts?

A: BFC238312683 is supplied in Tape & Reel (TR) packaging with 1172 units in inventory. B32652A6683J000 is supplied in Bulk packaging with 3491 units available. Packaging selection depends on procurement volume and handling requirements.

Q: Does the substitute part have automotive qualification?

A: B32652A6683J000 carries AEC-Q200 automotive qualification, suitable for automotive applications. BFC238312683 does not carry this designation. For automotive applications, the substitute part is the appropriate selection.
