Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPFF4S68J-F is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 0.068 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.720 inches / 18.30 mm (exact match required)

Allowable Variation Parameters:

• Voltage Rating - DC: Equal to or greater than 400V
• Voltage Rating - AC: Equal to or greater than 200V
• Operating Temperature Range: May differ if application requirements are met
• Physical Dimensions: May vary within PCB layout constraints
• Series Designation: May differ (DPFF vs. Orange Drop® 715P)

The substitute part 715P68356LD3 meets all mandatory matching criteria and provides an elevated DC voltage rating of 600V, making it suitable for applications requiring higher voltage margin or operating in elevated voltage environments.

Both parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 and HTSUS 8532.25.0070. Selection between these parts depends on voltage rating requirements and physical space constraints within the target application.

Frequently Asked Questions (FAQ)

Q: Can 715P68356LD3 directly replace DPFF4S68J-F in all applications?

A: Direct replacement is possible only when PCB layout accommodates the increased seated height of 22.70 mm (versus 14.00 mm) and the cylindrical form factor. The 600V DC rating of 715P68356LD3 is compatible with 400V DC applications, providing additional voltage margin. Operating temperature range differs: 715P68356LD3 is limited to 85°C maximum versus 105°C for DPFF4S68J-F.

Q: What are the physical dimension differences between these parts?

A: DPFF4S68J-F has a rectangular profile measuring 33.00 mm length × 14.00 mm width with 14.00 mm seated height. 715P68356LD3 has a cylindrical profile measuring 31.80 mm length × 15.20 mm diameter with 22.70 mm seated height. Both maintain identical 18.30 mm lead spacing for PCB hole compatibility.

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

A: DPFF4S68J-F is specified for high pulse and DV/DT applications. 715P68356LD3 is specified for audio, high frequency, switching, high pulse, DV/DT, and snubber applications. Both polypropylene metallized dielectric constructions support these application categories.

Q: What is the inventory status for each part?

A: DPFF4S68J-F has 913 units in stock (new original). 715P68356LD3 has 1780 units in stock (new original, bulk packaging). Both are Active products from Cornell Dubilier Electronics.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 under ECCN regulations. DPFF4S68J-F has MSL 1 (Unlimited). 715P68356LD3 has MSL Not Applicable. Both are suitable for regulated applications requiring these certifications.
