Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPM6P68K-F is determined by strict alignment of the following parameters:

Mandatory Matching Parameters:

• Capacitance value: 0.68 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating DC: 630V (minimum acceptable)
• Voltage Rating AC: 250V (minimum acceptable)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Mounting Type: Through Hole, Radial (exact match required)
• Lead Spacing: 1.083" (27.50mm) (exact match required)
• Termination: PC Pins (exact match required)

Compliance Parameters:

• RoHS3 Compliant status required
• REACH Unaffected status required

The B32654A6684K000 from EPCOS - TDK Electronics qualifies as an equivalent substitute based on full alignment with all mandatory matching parameters and compliance requirements. Physical dimensions and operating temperature ranges may vary within acceptable engineering tolerances for through-hole radial film capacitors.

Engineering Selection Recommendations

DPM6P68K-F Selection Criteria:

• Primary choice when maximum operating temperature of 105°C is required
• Preferred when larger physical envelope is acceptable or required by design
• Suitable for applications requiring CDE DPM series qualification or legacy system compatibility
• Active product status with 1004 units in stock

B32654A6684K000 Selection Criteria:

• Equivalent substitute when operating temperature maximum of 100°C is acceptable
• Preferred when compact form factor is advantageous (lower profile: 0.827" vs 1.201" seated height)
• Suitable for space-constrained PCB layouts while maintaining identical electrical performance
• Active product status with 2331 units in stock (higher availability)
• EPCOS - TDK Electronics B3265* MKP General Purpose series qualification

Both parts maintain full electrical equivalence for DC Link, DC Filtering, and High Frequency Switching applications. Selection between these parts is based on thermal operating range requirements, physical space constraints, and supply chain availability. Both parts carry identical compliance certifications (RoHS3, REACH Unaffected, EAR99, HTSUS 8532.25.0070).

Frequently Asked Questions (FAQ)

Q: Can B32654A6684K000 replace DPM6P68K-F in all applications?

A: Yes, for applications where the maximum operating temperature does not exceed 100°C. The B32654A6684K000 operates to 100°C maximum, while the DPM6P68K-F operates to 105°C maximum. All other electrical parameters are identical. If your application requires operation above 100°C, the DPM6P68K-F is required.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: Lead spacing is identical at 1.083" (27.50mm), ensuring footprint compatibility. However, the B32654A6684K000 has a lower seated height (0.827" vs 1.201") and smaller body dimensions (31.50mm x 11.00mm vs 32.00mm x 15.50mm). Verify clearance in your specific PCB layout, particularly for height-constrained applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both DPM6P68K-F and B32654A6684K000 are RoHS3 Compliant, REACH Unaffected, classified as EAR99, and carry the same HTSUS code 8532.25.0070.

Q: What is the difference in capacitance tolerance between these parts?

A: Both parts carry ±10% tolerance. There is no difference in tolerance specification.

Q: Which part should I select for new designs?

A: Selection depends on thermal requirements. For new designs without specific thermal constraints above 100°C, the B32654A6684K000 offers higher inventory availability (2331 units vs 1004 units) and a more compact form factor. For designs requiring 105°C operation or CDE series qualification, select the DPM6P68K-F.

Q: Are there any differences in ESR or ESL characteristics?

A: The DPM6P68K-F is specified with Low ESR and Low ESL features. The B32654A6684K000 does not list specific ESR/ESL values in the provided data. For applications where ESR/ESL specifications are critical, confirm B32654A6684K000 performance data with the manufacturer.

Q: Can these parts be used interchangeably in DC Link and DC Filtering applications?

A: Yes. Both parts are rated for DC Link and DC Filtering applications with identical 630V DC and 250V AC voltage ratings. The B32654A6684K000 additionally supports High Pulse and DV/DT applications.
