Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPFF8S47J-F are identified based on strict electrical and mechanical parameter matching. The substitution logic requires:

Electrical Equivalence:

• Capacitance value of 0.047 µF (exact match)
• DC voltage rating of 800V (exact match)
• AC voltage rating of 450V (exact match)
• Tolerance of ±5% or tighter
• Polypropylene metallized dielectric material

Mechanical Compatibility:

• Through-hole radial mounting configuration
• Lead spacing of 1.094" (27.80mm) for PCB hole pattern alignment
• PC pin termination for standard soldering processes

Regulatory Compliance:

• ROHS3 compliance maintained
• REACH unaffected status
• EAR99 export classification

The substitute part 715P47358MD3 meets all electrical specifications and mechanical requirements. Physical dimensions differ (cylindrical form factor vs. rectangular), but lead spacing and mounting type remain compatible with the original PCB design.

Engineering Selection Recommendations

Primary Part: DPFF8S47J-F

The DPFF8S47J-F remains the preferred selection for applications requiring the full operating temperature range of -55°C to 105°C. This part is Active status with 866 units in inventory, ensuring supply continuity. ROHS3 compliance and REACH unaffected status satisfy regulatory requirements for industrial and commercial applications.

Substitute Part: 715P47358MD3 (Orange Drop® 715P Series)

The 715P47358MD3 provides electrical equivalence with identical capacitance, voltage ratings, tolerance, and dielectric material. This part is also Active status with 943 units available. The substitute operates within -55°C to 85°C, which covers standard industrial temperature ranges but does not extend to the upper 105°C limit of the primary part.

Selection Criteria:

• Use DPFF8S47J-F for applications with sustained operation above 85°C
• Use 715P47358MD3 when operating temperature does not exceed 85°C and inventory availability is prioritized
• Both parts maintain identical electrical performance within their respective temperature ranges
• Both parts satisfy ROHS3 and REACH compliance requirements
• Lead spacing and mounting configuration are identical, ensuring PCB compatibility without layout modification

Frequently Asked Questions (FAQ)

Q: Can 715P47358MD3 replace DPFF8S47J-F in all applications?

A: The 715P47358MD3 provides electrical equivalence for capacitance, voltage rating, and tolerance. However, the operating temperature range differs. The substitute operates to 85°C maximum, while the primary part operates to 105°C. Use the substitute only in applications where the maximum ambient or component temperature does not exceed 85°C.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: Yes. Both parts share identical lead spacing of 1.094" (27.80mm) and radial through-hole mounting configuration. PCB hole patterns require no modification. Physical form factors differ (rectangular vs. cylindrical), but this does not affect electrical performance or mounting compatibility.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both DPFF8S47J-F and 715P47358MD3 are ROHS3 compliant and REACH unaffected. Both carry EAR99 export classification. Regulatory status is identical between the two parts.

Q: What is the difference between the DPFF and Orange Drop® 715P series?

A: Both are Cornell Dubilier Electronics products with identical electrical specifications for this capacitance value. The DPFF series operates to 105°C, while the Orange Drop® 715P series operates to 85°C. Series designation reflects product line organization but does not indicate performance differences within the specified temperature range.

Q: Can I use either part interchangeably based on inventory availability?

A: Interchangeability depends on application temperature requirements. If the circuit operates entirely within -55°C to 85°C, either part is suitable. If sustained operation above 85°C is required, use only DPFF8S47J-F. Verify application temperature specifications before selecting based on inventory alone.

Q: Are there any performance differences in high-pulse or DV/DT applications?

A: Both parts are rated for high-pulse and DV/DT applications with identical polypropylene metallized dielectric material. Performance characteristics are equivalent within their respective operating temperature ranges. Application suitability is determined by temperature requirements, not by series designation.
