Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 168682K250A-F is determined by strict adherence to the following criteria:

Mandatory Parameters (No Deviation Allowed):

• Capacitance value: 6800 pF
• Mounting type: Through-hole radial
• Lead spacing: 0.197" (5.00mm)
• Dielectric material: Polyester-based, metallized construction
• Operating temperature range: -55°C to 125°C minimum
• RoHS3 compliance

Acceptable Parameter Variations:

• Voltage rating: Equal to or greater than 250V DC / 160V AC
• Tolerance: Equal to or tighter than ±10%
• Physical dimensions: Minor variations acceptable if lead spacing and mounting type remain constant

The two identified substitutes (B32529C3682J000 and B32529C6682J000) meet all mandatory parameters. B32529C3682J000 maintains the 250V DC rating with improved ±5% tolerance. B32529C6682J000 provides enhanced voltage capability at 400V DC with ±5% tolerance, suitable for applications requiring higher voltage margins.

Parameter Comparison

Engineering Selection Recommendations

B32529C3682J000 Selection Criteria: This substitute maintains electrical equivalence at the 250V DC / 160V AC rating while providing tighter ±5% tolerance compared to the original ±10% specification. The part carries AEC-Q200 automotive qualification and is suitable for applications where tolerance improvement is beneficial without requiring elevated voltage capability. Inventory availability is significantly higher at 7,623 units.

B32529C6682J000 Selection Criteria: This substitute provides 400V DC / 200V AC rating, representing a 60% increase in voltage capability over the original specification. The ±5% tolerance improvement is maintained. AEC-Q200 automotive qualification is included. This part is appropriate for applications where higher voltage margins are required or where component standardization across multiple voltage-rated designs is desired. Inventory availability is substantially higher at 97,664 units.

Compliance Considerations: All three parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for both original and substitute selections. The EPCOS B3252* series components carry AEC-Q200 qualification, providing additional assurance for automotive and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can B32529C3682J000 be used as a direct replacement for 168682K250A-F?

A: Yes. Both parts share identical capacitance (6800 pF), voltage rating (250V DC / 160V AC), operating temperature range (-55°C to 125°C), lead spacing (5.00mm), and mounting configuration (through-hole radial). The substitute provides improved ±5% tolerance versus the original ±10%. Physical dimensions vary slightly (7.30mm vs 7.20mm length), but both fit standard 5.00mm lead spacing PCB layouts.

Q: What is the primary advantage of B32529C6682J000?

A: The primary advantage is elevated voltage rating at 400V DC / 200V AC, providing 60% higher voltage capability than the original 250V DC specification. This allows use in higher-voltage circuit designs or provides increased safety margin in existing applications. Tolerance is also improved to ±5%.

Q: Are there any physical compatibility concerns with the EPCOS substitutes?

A: Physical dimensions are nearly identical. The EPCOS parts measure 7.30mm length versus 7.20mm for the CDE original, a 0.10mm difference. Lead spacing remains 5.00mm, and seated height is 6.50mm for all three parts. This minor dimensional variation does not affect PCB compatibility for standard through-hole radial layouts.

Q: Do the substitute parts carry automotive qualification?

A: Yes. Both EPCOS B32529C3682J000 and B32529C6682J000 carry AEC-Q200 qualification, suitable for automotive applications. The original CDE 168682K250A-F does not list automotive qualification.

Q: What is the difference between the two EPCOS substitutes?

A: The primary difference is voltage rating. B32529C3682J000 maintains 250V DC matching the original, while B32529C6682J000 provides 400V DC. Both offer ±5% tolerance improvement. Selection depends on circuit voltage requirements.

Q: Are all three parts RoHS compliant?

A: Yes. The CDE 168682K250A-F and both EPCOS substitutes are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: Which substitute should be selected for general-purpose applications?

A: B32529C3682J000 is appropriate for general-purpose applications matching the original 250V DC specification with tolerance improvement. B32529C6682J000 is selected when higher voltage capability is required or when standardizing across multiple voltage-rated designs.
