Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPFF8S68J-F is determined by strict alignment of electrical and mechanical parameters. The following criteria establish valid substitutes:

Electrical Parameters (Non-negotiable):

• Capacitance value: 0.068 µF (exact match required)
• Tolerance: ±5% (substitute tolerance must not exceed this value)
• DC voltage rating: 800V minimum (substitute must equal or exceed)
• AC voltage rating: 450V minimum (substitute must equal or exceed)
• Dielectric type: Polypropylene metallized (required for application performance)

Mechanical Parameters (Non-negotiable):

• Mounting type: Through Hole (PCB assembly compatibility)
• Lead spacing: 1.094" (27.80mm) (PCB footprint requirement)
• Package type: Radial (form factor compatibility)

Compliance Parameters:

• RoHS3 compliance status (regulatory requirement)
• REACH unaffected status (regulatory requirement)

The substitute part 715P68358MD3 meets all electrical and mechanical criteria. Dimensional variations in body size and height are acceptable provided lead spacing and mounting type remain constant.

Engineering Selection Recommendations

Primary Part: DPFF8S68J-F

Use the DPFF8S68J-F when the original design specifications require the exact physical dimensions (1.701" L x 0.799" W, 20.30mm seated height). This part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The operating temperature range of -55°C to 105°C supports applications requiring extended high-temperature performance.

Substitute Part: 715P68358MD3

The 715P68358MD3 (Orange Drop® 715P series) is electrically equivalent and mechanically compatible for PCB footprint purposes, with identical lead spacing of 1.094" (27.80mm). This substitute maintains ROHS3 compliance and REACH unaffected status. The substitute exhibits different body dimensions and a maximum seated height of 0.894" (22.70mm), which is 0.095" taller than the primary part.

Selection Criteria:

• Use 715P68358MD3 when: PCB layout accommodates the taller profile (22.70mm vs 20.30mm), and operating temperature requirements do not exceed 85°C. This part offers higher inventory availability (1938 units vs 970 units).

• Use DPFF8S68J-F when: Space constraints require the lower profile, or operating temperatures must reach 105°C.

Both parts are Active products from the same manufacturer with identical electrical specifications, ensuring functional interchangeability within the stated mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can 715P68358MD3 be used as a direct replacement for DPFF8S68J-F?

A: The 715P68358MD3 is electrically equivalent and shares identical lead spacing (1.094" / 27.80mm), making it mechanically compatible for PCB assembly. However, the substitute is 0.095" taller (22.70mm vs 20.30mm seated height). Verify that your PCB layout and enclosure clearances accommodate this dimensional difference before substitution.

Q: What is the operating temperature difference between these parts?

A: The DPFF8S68J-F operates from -55°C to 105°C, while the 715P68358MD3 operates from -55°C to 85°C. If your application requires sustained operation above 85°C, the DPFF8S68J-F is the required choice.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both DPFF8S68J-F and 715P68358MD3 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Do these parts have identical electrical specifications?

A: Yes. Both parts share identical capacitance (0.068 µF), tolerance (±5%), DC voltage rating (800V), AC voltage rating (450V), and dielectric material (polypropylene metallized). Electrical performance is equivalent.

Q: What is the lead spacing for both parts?

A: Both parts have a lead spacing of 1.094" (27.80mm), ensuring PCB footprint compatibility. This parameter is critical for through-hole assembly and must match your PCB design.

Q: Why do the body dimensions differ if the parts are substitutes?

A: Different manufacturers or product series may use different physical packaging while maintaining identical electrical specifications and lead spacing. The 715P68358MD3 (Orange Drop® series) uses a cylindrical form factor, while the DPFF8S68J-F uses a rectangular form factor. Both are valid radial through-hole packages with the same lead spacing.

Q: Which part should I choose for new designs?

A: For new designs, either part is acceptable provided your PCB layout accommodates the dimensional specifications. The 715P68358MD3 offers higher inventory availability. The DPFF8S68J-F is preferred if your design requires the lower profile or extended temperature range to 105°C.

Q: Are there any application differences between these parts?

A: The DPFF8S68J-F is specified for high-pulse and DV/DT applications. The 715P68358MD3 is specified for audio, high-frequency switching, high-pulse, DV/DT, and snubber applications. Both are suitable for high-pulse and DV/DT use cases.
