DPFF6S68J-F

Part Overview

The DPFF6S68J-F is a 0.068 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 630V DC operation. This radial polypropylene (PP) metallized capacitor is designed for high-pulse and DV/DT applications with operating temperatures ranging from -55°C to 105°C. The part is currently in active production status with ROHS3 compliance and REACH unaffected status. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific application requirements necessitate alternative electrical or mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of film capacitors is determined by matching critical electrical and mechanical parameters. The primary criteria for equivalent substitution are:

• Capacitance Value and Tolerance: Must be identical (0.068 µF at ±5%)
• Voltage Rating: The substitute must meet or exceed the DC voltage rating of the original part
• Dielectric Material: Polypropylene (PP), metallized construction ensures comparable frequency and pulse response characteristics
• Mounting Type and Lead Spacing: Through-hole mounting with 0.720" lead spacing ensures mechanical compatibility with existing PCB layouts
• Temperature Range: The operating temperature specification determines suitability for the intended thermal environment

The substitute part 715P68356LD3 shares the same capacitance value, tolerance, AC voltage rating, dielectric material, mounting type, and lead spacing. However, the DC voltage rating of 600V is 30V lower than the primary part's 630V rating, and the maximum operating temperature is reduced from 105°C to 85°C.

Parameter Comparison

Engineering Selection Recommendations

Both the DPFF6S68J-F and 715P68356LD3 are ROHS3 compliant and REACH unaffected, meeting contemporary environmental and regulatory standards. Both parts are manufactured by Cornell Dubilier Electronics and maintain active production status, ensuring consistent availability and supply chain stability.

Selection between these parts must be based on circuit-level requirements. The primary differences are the DC voltage rating (630V versus 600V) and maximum operating temperature (105°C versus 85°C). The DPFF6S68J-F is appropriate for applications requiring the full 630V DC rating or operating environments exceeding 85°C. The 715P68356LD3 (Orange Drop® 715P series) is suitable for applications with 600V DC maximum voltage and operating temperatures not exceeding 85°C.

Frequently Asked Questions (FAQ)

What is the primary difference between DPFF6S68J-F and 715P68356LD3?

The DPFF6S68J-F has a higher DC voltage rating (630V versus 600V) and extended maximum operating temperature (105°C versus 85°C). Both parts share identical capacitance (0.068 µF), tolerance (±5%), AC voltage rating (200V), and lead spacing (0.720").

Can 715P68356LD3 be used as a drop-in replacement for DPFF6S68J-F?

Direct substitution is limited to applications where the circuit operates below 600V DC and ambient temperatures do not exceed 85°C. If the application requires the full 630V rating or operates above 85°C, the 715P68356LD3 is not suitable. Lead spacing and mounting type are identical, ensuring mechanical compatibility.

Are both parts suitable for high-pulse and DV/DT applications?

The DPFF6S68J-F is explicitly rated for high-pulse and DV/DT applications. The 715P68356LD3 is rated for audio, high-frequency, switching, high-pulse, DV/DT, and snubber applications. Both polypropylene metallized constructions support high-frequency pulse response requirements.

What is the significance of lead spacing in substitution?

Both parts maintain 0.720" (18.30mm) lead spacing, ensuring compatibility with existing PCB pad layouts and through-hole mounting patterns without requiring board redesign or drilling modifications.

Do both parts meet current environmental compliance standards?

Both the DPFF6S68J-F and 715P68356LD3 are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components in most jurisdictions.
