Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC238501682 is determined by the following critical parameters:

• Capacitance Value: Must be 6800 pF (no tolerance variation acceptable for direct substitution)
• DC Voltage Rating: Minimum 1600V DC required
• Tolerance: ±5% specification must be maintained
• Dielectric Type: Polypropylene (PP), Metallized construction required
• Mounting Configuration: Through-hole radial package with 15.00mm lead spacing
• Operating Temperature: -55°C to 110°C range must be supported
• Termination Style: PC pins required for PCB compatibility

The substitute part B32672L1682J000 meets all critical substitution criteria. While the AC voltage rating differs (600V vs. 550V), this parameter does not restrict DC application suitability. Physical dimensions show minor variations within acceptable assembly tolerances for radial through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations

The B32672L1682J000 (EPCOS - TDK Electronics) is a direct functional equivalent to the BFC238501682. Both components are ROHS3 compliant and maintain identical electrical specifications for capacitance, tolerance, DC voltage rating, dielectric material, and operating temperature range. The substitute part carries a higher AC voltage rating (600V vs. 550V), which provides additional margin in AC stress conditions without affecting DC application performance.

Physical dimensions show minor variations: the substitute is 0.5mm longer and 0.5mm shorter in height. These differences fall within standard PCB assembly tolerances for radial through-hole components and do not impact board layout or mechanical fit. Lead spacing remains identical at 15.00mm, ensuring direct PCB footprint compatibility.

Both parts are active production items with established supply availability. Selection between these components should be based on procurement lead times, cost considerations, and inventory status rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can B32672L1682J000 be used as a direct replacement for BFC238501682 in existing designs?

A: Yes. Both components share identical capacitance (6800 pF), tolerance (±5%), DC voltage rating (1600V), dielectric material (polypropylene metallized), operating temperature range (-55°C to 110°C), and lead spacing (15.00mm). Physical dimension variations are within standard assembly tolerances for radial through-hole mounting.

Q: Does the higher AC voltage rating on the substitute part affect DC circuit performance?

A: No. AC voltage rating is independent of DC application performance. The substitute's 600V AC rating provides additional stress margin and does not alter DC filtering, DC link, or switching circuit behavior.

Q: Are there any compliance or certification differences between these parts?

A: Both components are ROHS3 compliant. The substitute carries REACH Unaffected status, while the original part lists Moisture Sensitivity Level 1 (Unlimited). Both certifications are standard for this component category and do not restrict interchangeability.

Q: Will the 0.5mm length difference cause PCB assembly issues?

A: No. Radial through-hole capacitors with lead spacing of 15.00mm accommodate standard PCB hole tolerances. A 0.5mm length variation is within normal manufacturing tolerances and does not affect insertion, soldering, or mechanical stability.

Q: What applications are these capacitors suitable for?

A: Both components are rated for DC link, DC filtering, high frequency switching, and high pulse DV/DT applications. Identical electrical specifications ensure equivalent performance across all specified use cases.
