The KEMET R75MI26804030J meets all mandatory matching criteria and exceeds allowable upgrade parameters, qualifying as a direct electrical and mechanical substitute.

Parameter Comparison

Engineering Selection Recommendations

The KEMET R75MI26804030J qualifies as a direct substitute for the DPP2S68K-F based on the following engineering criteria:

Electrical Compatibility: Both components share identical capacitance (0.068 µF) and dielectric material (metallized polypropylene). The KEMET substitute provides higher voltage ratings (400V DC / 220V AC versus 250V DC / 140V AC), which represents an upgrade suitable for applications requiring the original part's specifications.

Mechanical Compatibility: Lead spacing (0.591" / 15.00mm) and radial through-hole mounting are identical, ensuring direct PCB footprint compatibility without layout modifications.

Tolerance Improvement: The KEMET part offers ±5% tolerance compared to the original ±10%, providing tighter capacitance control when required by circuit design.

Regulatory Compliance: Both parts maintain ROHS3 Compliant and REACH Unaffected status, satisfying environmental and regulatory requirements.

Product Status: Both components are Active products with confirmed inventory availability, supporting production continuity.

Temperature Performance: Identical operating temperature range (-55°C ~ 105°C) ensures thermal compatibility across all specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the KEMET R75MI26804030J replace the DPP2S68K-F in existing designs?

A: Yes. The substitute part matches all mandatory electrical and mechanical parameters: capacitance (0.068 µF), dielectric material (metallized polypropylene), lead spacing (15.00mm), and mounting type (radial through-hole). PCB footprint compatibility is maintained without design changes.

Q: What are the advantages of using the KEMET substitute?

A: The R75MI26804030J provides higher voltage ratings (400V DC versus 250V DC) and tighter tolerance (±5% versus ±10%), offering improved performance margin and capacitance stability. Both parts share identical operating temperature range and regulatory compliance status.

Q: Are there any physical dimension differences between these parts?

A: Yes. The KEMET R75MI26804030J has different overall dimensions (18.00mm L x 5.00mm W, 11.10mm height) compared to the CDE DPP2S68K-F (20.00mm L x 11.00mm W, 19.00mm height). However, lead spacing remains identical at 15.00mm, ensuring PCB compatibility. Physical space constraints must be evaluated for the specific application.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the DPP2S68K-F and R75MI26804030J are ROHS3 Compliant and REACH Unaffected, satisfying equivalent environmental and regulatory requirements.

Q: What is the significance of the tighter tolerance on the KEMET part?

A: The ±5% tolerance on the R75MI26804030J provides tighter capacitance control compared to the ±10% tolerance of the DPP2S68K-F. This is beneficial for applications requiring precise capacitance values but does not prevent substitution in applications designed for ±10% tolerance.

Q: Are both parts suitable for high-frequency and switching applications?

A: The DPP2S68K-F is specified for high-frequency and switching applications with low ESR performance. The KEMET R75MI26804030J is specified for automotive, high-frequency, switching, and high pulse DV/DT applications. Both are suitable for the original part's intended use cases.
