Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 168682K100A-F is based on strict electrical and mechanical parameter alignment. All substitute parts maintain the identical 6800 pF capacitance value, polyester dielectric material, through-hole radial mounting configuration, 5.00mm lead spacing, and -55°C to 125°C operating temperature range. The key differentiators among substitutes are:

Tolerance Enhancement: The main part specifies ±10% tolerance. All EPCOS B3252* series substitutes provide ±5% tolerance, representing improved capacitance accuracy while maintaining backward compatibility.

Voltage Rating Flexibility: Substitutes are available in three voltage configurations—100V DC (B32529C1682J000), 250V DC (B32529C3682J000), and 400V DC (B32529C6682J000)—allowing selection based on circuit voltage requirements. Higher voltage ratings are electrically compatible with lower-voltage applications.

Automotive Certification: EPCOS substitutes carry AEC-Q200 qualification, enabling use in automotive and industrial environments where the original CDE part may not be specified.

Dielectric Construction: EPCOS parts utilize Polyethylene Terephthalate (PET) metallized stacked construction, functionally equivalent to the polyester metallized design of the original part.

All substitutes maintain ROHS3 compliance and EAR99 export classification consistent with the original part.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Same Voltage Rating)

B32529C1682J000 serves as a direct electrical and mechanical replacement for 168682K100A-F. Both parts operate at 100V DC / 63V AC with identical lead spacing and mounting footprint. The B32529C1682J000 provides superior capacitance tolerance (±5% versus ±10%), enabling tighter circuit performance specifications. This substitute is appropriate for applications where tolerance improvement is beneficial without circuit redesign.

Higher Voltage Applications

B32529C3682J000 (250V DC) and B32529C6682J000 (400V DC) are suitable for circuits requiring elevated voltage margins or operating in higher-voltage environments. These parts maintain identical capacitance, lead spacing, and physical dimensions, ensuring PCB compatibility. Selection depends on circuit voltage requirements and design safety margins.

Automotive and Industrial Environments

All EPCOS B3252* series substitutes carry AEC-Q200 automotive qualification, enabling deployment in automotive, industrial, and mission-critical applications where this certification is specified. The original CDE part lacks this designation.

Compliance and Availability

All parts maintain ROHS3 compliance and active product status. EPCOS substitutes demonstrate significantly higher inventory availability (2136 to 97664 units) compared to the original part (1030 units), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can B32529C1682J000 replace 168682K100A-F in existing designs without modification?

A: Yes. B32529C1682J000 maintains identical voltage ratings (100V DC / 63V AC), capacitance (6800 pF), lead spacing (5.00mm), and physical dimensions (0.256" seated height). The ±5% tolerance is tighter than the original ±10%, improving circuit performance. No PCB or schematic changes are required.

Q: What is the difference between B32529C1682J000, B32529C3682J000, and B32529C6682J000?

A: These three parts differ only in voltage rating. B32529C1682J000 is rated 100V DC (equivalent to the original part). B32529C3682J000 is rated 250V DC. B32529C6682J000 is rated 400V DC. All other electrical and mechanical parameters remain identical. Selection depends on circuit voltage requirements.

Q: Are EPCOS B3252 parts suitable for automotive applications?*

A: Yes. All EPCOS B3252* series substitutes carry AEC-Q200 automotive qualification. The original CDE 168682K100A-F does not specify this certification. Use EPCOS parts when automotive-grade components are required.

Q: Does the ±5% tolerance of EPCOS parts affect circuit compatibility?

A: No. Tighter tolerance (±5%) is a performance enhancement over the original ±10% specification. Circuits designed for ±10% tolerance operate within specification with ±5% components. The improved tolerance may enhance circuit accuracy and stability.

Q: Can higher-voltage substitutes (250V or 400V) be used in 100V circuits?

A: Yes. Higher voltage-rated capacitors are electrically compatible with lower-voltage applications. The 250V and 400V rated parts operate safely in 100V circuits. Selection of higher voltage ratings provides additional design margin and reliability in applications subject to voltage transients or overvoltage conditions.

Q: Are the physical dimensions identical across all substitutes?

A: Yes. All parts maintain identical lead spacing (5.00mm), seated height (6.50mm), and radial through-hole configuration. PCB layouts designed for 168682K100A-F accommodate all EPCOS B3252* substitutes without modification.

Q: What is the inventory status of these parts?

A: 168682K100A-F: 1030 units. B32529C1682J000: 2136 units. B32529C3682J000: 7623 units. B32529C6682J000: 97664 units. All parts maintain active product status with current availability.
