BFC233660682 Film Capacitor - Equivalent & Substitute Parts

Part Overview

The BFC233660682 is a 6800 pF metallized polypropylene film capacitor manufactured by Vishay Beyschlag/Draloric/BC Components, rated for 1000V DC operation. This radial through-hole component is designed for EMI and RFI suppression applications with a ±20% capacitance tolerance and Y2 safety rating. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when inventory constraints, lead time requirements, or specific application voltage margins necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC233660682 is determined by the following critical parameters:

• Capacitance Value: Must be 6800 pF (exact match required)
• Capacitance Tolerance: Must be ±20% or tighter
• Dielectric Material: Must be Polypropylene (PP), Metallized
• Mounting Type: Must be Through Hole
• Package Type: Must be Radial
• Lead Spacing: Must be 0.394" (10.00mm)
• Termination: Must be PC Pins
• Safety Rating: Must be Y2
• Voltage Rating - DC: Must be ≥1000V (1kV)
• Voltage Rating - AC: Must be ≥300V

The substitute part B32021A3682M289 meets all substitution criteria with an elevated DC voltage rating of 1500V (1.5kV), providing additional voltage margin while maintaining identical capacitance, tolerance, dielectric material, mounting configuration, and lead spacing.

Parameter Comparison

Engineering Selection Recommendations

Both the BFC233660682 and B32021A3682M289 are active production parts with ROHS3 compliance and Y2 safety certification, meeting regulatory requirements for equivalent component selection.

The BFC233660682 operates within a -55°C to 105°C temperature range and is specified for 1000V DC operation. The B32021A3682M289 substitute operates within -40°C to 110°C and is rated for 1500V DC, providing 500V additional voltage margin. Selection between these parts depends on application-specific temperature requirements and voltage stress conditions. The substitute part is 2mm longer in length (13.00mm vs. 12.50mm), which must be verified against PCB layout constraints and available board space. Both parts maintain identical lead spacing (10.00mm), capacitance value (6800 pF), and radial through-hole mounting configuration, ensuring direct functional substitution in standard circuit board designs where physical dimensions are accommodated.

Frequently Asked Questions (FAQ)

Q: Can B32021A3682M289 be used as a direct replacement for BFC233660682?

A: Yes, provided that the 2mm additional length (13.00mm vs. 12.50mm) does not conflict with PCB layout constraints. All electrical parameters, lead spacing, and mounting type are compatible. The substitute part's higher voltage rating (1500V vs. 1000V) does not create incompatibility.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) DC voltage rating—B32021A3682M289 is rated 1500V versus 1000V for BFC233660682; (2) physical length—B32021A3682M289 is 13.00mm versus 12.50mm; (3) operating temperature range—BFC233660682 extends to -55°C while B32021A3682M289 starts at -40°C; (4) manufacturer—Vishay versus EPCOS/TDK. Capacitance, tolerance, dielectric material, lead spacing, and safety rating are identical.

Q: Are there any PCB layout considerations when substituting B32021A3682M289 for BFC233660682?

A: The substitute part is 2mm longer. Verify that the additional length does not interfere with adjacent components, solder joints, or board edge clearances. Lead spacing remains 10.00mm, so through-hole pad positioning requires no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry Y2 safety ratings, meeting equivalent regulatory requirements for equivalent component selection in compliant applications.

Q: What is the significance of the Y2 safety rating?

A: Y2 rating indicates these capacitors are approved for use in applications where component failure does not result in hazardous voltage exposure. Both parts carry this identical certification.
