Substitute Part Grouping Explanation

Substitution eligibility for the 168682J400C-F is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 6800 pF (exact match)
• Tolerance: ±5% (exact match)
• Voltage Rating - DC: 400V (minimum requirement; higher ratings acceptable)
• Voltage Rating - AC: 200V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polyester, Metallized (functional equivalence)
• Operating Temperature Range: -55°C to 125°C (minimum requirement; extended ranges acceptable)

Mechanical Equivalence Requirements:

• Mounting Type: Through Hole (exact match)
• Package Type: Radial (exact match)
• Lead Spacing: 0.197" (5.00mm) (exact match for PCB compatibility)
• Termination: PC Pins (exact match)

Compliance Requirements:

• RoHS3 Compliant (mandatory for modern applications)
• REACH Unaffected status (mandatory for regulatory compliance)

The substitute part B32529C6682J000 meets all electrical and mechanical equivalence criteria, with identical capacitance, tolerance, voltage ratings, temperature range, and lead spacing. Physical dimensions differ slightly but remain within acceptable radial package tolerances for through-hole PCB mounting.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection - 168682J400C-F (Cornell Dubilier Electronics): Select this part when CDE component qualification is required or when existing inventory supports production continuity. The part maintains Active product status with established supply availability (985 units in stock). ROHS3 compliance and REACH Unaffected status satisfy modern regulatory requirements. General-purpose application classification provides broad compatibility across standard circuit designs.

Equivalent Alternative - B32529C6682J000 (EPCOS - TDK Electronics): This substitute provides functional equivalence with identical electrical specifications and lead spacing. The B32529C6682J000 series carries AEC-Q200 automotive qualification, indicating enhanced reliability screening suitable for demanding environments. Significantly higher inventory availability (97,664 units) supports extended production runs and reduces supply chain risk. The stacked radial construction with slightly reduced physical dimensions (0.256" seated height versus 0.295") offers improved PCB layout flexibility in space-constrained applications. Both parts maintain ROHS3 compliance and REACH Unaffected status.

Selection Criteria:

• Use 168682J400C-F for CDE-qualified designs or when existing component qualification documentation is required
• Use B32529C6682J000 for supply chain optimization, automotive-grade reliability requirements, or when compact package dimensions are beneficial
• Both parts are interchangeable from electrical and mechanical perspectives within the specified operating parameters

Frequently Asked Questions (FAQ)

Q: Can B32529C6682J000 directly replace 168682J400C-F on existing PCBs?

A: Yes. Both parts share identical lead spacing (0.197" / 5.00mm), radial through-hole mounting configuration, and PC pin termination. Physical dimension variations (height difference of 0.039" / 1.00mm) do not affect PCB mounting compatibility. Verify clearance in applications with height-constrained layouts.

Q: Are the dielectric materials functionally equivalent?

A: Yes. Both parts utilize polyester-based metallized dielectric technology. The 168682J400C-F specifies polyester metallized construction, while the B32529C6682J000 specifies polyester polyethylene terephthalate (PET) metallized stacked construction. Both achieve identical electrical performance across the specified voltage and temperature ranges.

Q: What is the significance of AEC-Q200 qualification on the B32529C6682J000?

A: AEC-Q200 is an automotive industry standard qualification indicating enhanced reliability screening, including temperature cycling, vibration, and moisture resistance testing. This qualification is not required for general-purpose applications but provides additional assurance for automotive, industrial, or mission-critical environments.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the 168682J400C-F and B32529C6682J000 are ROHS3 compliant and REACH Unaffected, satisfying current environmental and hazardous substance regulations applicable to electronic components in most markets.

Q: Is there a performance difference between the two parts in DC filtering applications?

A: No. Both parts deliver equivalent performance in DC filtering, energy storage, and general-purpose circuit applications. Identical capacitance (6800 pF), tolerance (±5%), voltage rating (400V DC), and temperature range (-55°C to 125°C) ensure functionally identical behavior.

Q: Which part should be selected for new designs?

A: For new designs without existing component qualification requirements, the B32529C6682J000 offers advantages including higher inventory availability, automotive-grade reliability certification, and compact physical dimensions. The 168682J400C-F remains a valid selection when CDE component specifications are mandated by design standards or customer requirements.

Q: Are there any lead-time considerations between these parts?

A: The B32529C6682J000 maintains significantly higher inventory (97,664 units versus 985 units), potentially offering shorter lead times for high-volume production. Verify current availability with component distributors for time-sensitive applications.
