Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC237035682 is determined by the following criteria:

Primary Substitution Parameters:

• Capacitance value must equal 6800 pF
• Voltage rating (DC) must be equal to or greater than 250V
• Mounting type must be through-hole radial
• Dielectric material must be polyester-based (metallized)
• AEC-Q200 automotive qualification must be maintained
• RoHS3 compliance must be present

Secondary Considerations:

• Tolerance may be tighter (±5%) without affecting functionality
• Operating temperature range may be extended
• Lead spacing and physical dimensions may vary within mechanical compatibility limits
• Packaging format (tape & box vs. bulk) does not affect electrical performance

Three substitute parts meet these criteria with varying tolerance and voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

BFC237042682 (Vishay Beyschlag/Draloric/BC Components) This substitute provides identical electrical and mechanical specifications to the main part with the exception of tighter tolerance (±5% vs. ±10%). It maintains the same voltage rating, temperature range, and lead spacing. This part is suitable for applications where improved tolerance performance is beneficial. Both parts are from the same manufacturer series (MKT370) and carry equivalent AEC-Q200 automotive qualification.

B32529C3682J000 (EPCOS - TDK Electronics) This substitute maintains the 250V DC rating and 6800 pF capacitance with ±5% tolerance. The dielectric construction differs (stacked metallized PET vs. standard metallized polyester) and the operating temperature range extends to 125°C. Lead spacing is 0.197" (5.00mm) versus 0.200" (5.08mm) on the main part. This part is suitable for applications requiring extended temperature performance and is AEC-Q200 qualified.

B32529C6682J000 (EPCOS - TDK Electronics) This substitute provides the highest voltage rating at 400V DC with ±5% tolerance and extended temperature range to 125°C. The 6800 pF capacitance and radial through-hole mounting are maintained. Lead spacing is 0.197" (5.00mm). This part is appropriate for applications requiring higher voltage margin or operating in elevated temperature environments. AEC-Q200 qualification is maintained.

All substitute parts maintain ROHS3 compliance and automotive-grade reliability standards.

Frequently Asked Questions (FAQ)

Q: Can BFC237042682 be used as a direct replacement for BFC237035682? A: Yes. Both parts share identical capacitance (6800 pF), voltage rating (250V DC), operating temperature range (-55°C to 105°C), lead spacing (0.200"), and mounting configuration. The primary difference is tolerance specification (±5% vs. ±10%), which represents improved performance. Both are AEC-Q200 qualified from the same manufacturer series.

Q: What is the difference between the Vishay and EPCOS substitute parts? A: BFC237042682 (Vishay) maintains identical specifications to the main part with tighter tolerance. B32529C3682J000 and B32529C6682J000 (EPCOS) feature stacked metallized PET dielectric construction, extended temperature range to 125°C, and slightly different lead spacing (0.197" vs. 0.200"). B32529C6682J000 additionally provides 400V DC rating versus 250V DC.

Q: Are the lead spacing differences between 0.200" and 0.197" significant? A: Lead spacing differences of 0.003" (0.076mm) are within standard PCB design tolerances for through-hole radial components. Mechanical compatibility depends on specific PCB pad layout. Verify pad spacing in your design before substitution.

Q: Do all substitute parts carry automotive qualification? A: Yes. All listed substitute parts (BFC237042682, B32529C3682J000, B32529C6682J000) are AEC-Q200 qualified and suitable for automotive applications.

Q: Which substitute should be selected for high-temperature applications? A: B32529C3682J000 and B32529C6682J000 both support operating temperatures to 125°C, compared to 105°C for the main part and BFC237042682. Selection between these two depends on voltage requirement: 250V DC for B32529C3682J000 or 400V DC for B32529C6682J000.

Q: Is packaging format (tape & box vs. bulk) a factor in substitution? A: Packaging format does not affect electrical or mechanical performance. Selection between tape & box and bulk packaging is determined by assembly process requirements and inventory management practices.
