Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPFF6D68J-F is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance value: 6800 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Mounting type: Through Hole Radial (exact match required)
• Termination: PC Pins (exact match required)

Secondary Compatibility Criteria:

• Voltage Rating - DC: 630V minimum (equal or higher acceptable)
• Voltage Rating - AC: 200V minimum (equal or higher acceptable)
• Operating Temperature Range: -55°C to 105°C minimum (equal or wider acceptable)
• RoHS Compliance: ROHS3 Compliant (required for regulatory alignment)

The three identified substitute parts meet all primary matching criteria and maintain compatibility across secondary parameters. Physical dimensions and lead spacing may vary within acceptable through-hole mounting tolerances.

Engineering Selection Recommendations

715P68256JD3 (Cornell Dubilier Electronics - Orange Drop® 715P Series)

This substitute maintains identical capacitance, tolerance, and dielectric material specifications. The DC voltage rating of 600V is 30V lower than the main part; this represents a 4.8% reduction in voltage margin. The operating temperature range extends to 85°C maximum, which is 20°C lower than the DPFF6D68J-F specification. Selection of this part is appropriate for applications where the 600V DC rating and 85°C upper temperature limit satisfy circuit requirements. All regulatory certifications (ROHS3 Compliant, REACH Unaffected) align with the main part.

B32620A6682J000 (EPCOS - TDK Electronics - B3262 MKP High Pulse Series)*

This substitute matches the DC voltage rating (630V) and operating temperature range (-55°C to 105°C) of the main part. The AC voltage rating is elevated to 400V, providing additional margin. The dielectric construction uses a stacked metallized polypropylene configuration, which is a structural variant of the standard metallized polypropylene material. Physical dimensions are more compact (10.00mm x 5.00mm vs. 19.10mm x 11.40mm), and lead spacing is reduced to 7.50mm. All regulatory certifications match the main part specification. This part is suitable for applications where compact form factor and enhanced AC voltage rating are beneficial.

B32621A6682J000 (EPCOS - TDK Electronics - B3262 MKP High Pulse Series)*

This substitute provides identical DC voltage rating (630V) and operating temperature range (-55°C to 105°C) as the main part. AC voltage rating is 400V. The stacked metallized polypropylene dielectric construction matches B32620A6682J000. Physical dimensions are intermediate (13.00mm x 4.00mm) with lead spacing of 10.00mm. All regulatory certifications align with the main part. This part offers a balance between form factor and electrical performance for high-pulse applications.

All three substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 715P68256JD3 be used as a direct replacement for the DPFF6D68J-F?

A: The 715P68256JD3 is electrically compatible for applications where the 600V DC rating and -55°C to 85°C operating range are acceptable. The 30V reduction in DC voltage rating and 20°C reduction in maximum operating temperature represent the primary differences. Circuit design must confirm these parameters are within system requirements.

Q: What is the difference between standard metallized polypropylene and stacked metallized polypropylene?

A: Both dielectric constructions use polypropylene film with metallized electrodes. The stacked configuration in the B3262* series uses multiple layers of film stacked together, which can provide different electrical characteristics and physical form factors compared to the standard construction in the DPFF and 715P series. The capacitance value, tolerance, and voltage ratings remain equivalent.

Q: Are the physical dimensions critical for substitution?

A: Physical dimensions are important for PCB layout and mechanical fit. The DPFF6D68J-F measures 19.10mm x 11.40mm with 9.50mm lead spacing. The B32620A6682J000 is significantly more compact at 10.00mm x 5.00mm with 7.50mm lead spacing, while the B32621A6682J000 measures 13.00mm x 4.00mm with 10.00mm lead spacing. Verify that the substitute part's dimensions and lead spacing are compatible with the PCB design before implementation.

Q: Do all substitute parts have the same inventory availability?

A: No. The DPFF6D68J-F has 678 pieces in stock, while the 715P68256JD3 has 1166 pieces, B32620A6682J000 has 2407 pieces, and B32621A6682J000 has 3019 pieces available. Higher inventory levels for the EPCOS parts may provide supply chain advantages.

Q: Are all parts RoHS3 compliant?

A: Yes. The DPFF6D68J-F and all three substitute parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What applications are these capacitors suitable for?

A: The DPFF6D68J-F is specified for high-pulse and DV/DT applications. The 715P68256JD3 is rated for audio, high-frequency switching, high-pulse, DV/DT, and snubber applications. The B32620A6682J000 and B32621A6682J000 are specified for high-pulse and DV/DT applications. Application compatibility should be confirmed based on circuit requirements.
