Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for the DPPM16D68K-F are established based on the following criteria:

Electrical Equivalence Requirements:

• Capacitance value: 6800 pF (exact match)
• Voltage rating: 1600V DC minimum (1.6kV)
• Voltage rating: 500V AC minimum
• Dielectric material: Polypropylene (PP), Metallized

Mechanical Compatibility Requirements:

• Mounting type: Through Hole
• Package type: Radial configuration
• Termination: PC Pins

Regulatory & Compliance Requirements:

• RoHS3 Compliant status
• REACH Unaffected designation

The substitute part 715P682516LD3 meets all electrical equivalence and mechanical compatibility criteria. Tolerance variation (±5% versus ±10%) represents an improvement in capacitance accuracy. Operating temperature range differences and physical dimension variations are secondary considerations that do not prevent functional substitution when circuit design accommodates these parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The DPPM16D68K-F and 715P682516LD3 are electrically and mechanically equivalent for 6800 pF, 1.6 kV polypropylene film capacitor applications. Both parts are manufactured by Cornell Dubilier Electronics and maintain Active product status with full RoHS3 compliance and REACH unaffected designation.

Substitution Considerations:

1. Tolerance Specification: The 715P682516LD3 provides ±5% tolerance compared to ±10% for the DPPM16D68K-F. This represents improved capacitance accuracy and may be advantageous in precision circuit designs.

2. Operating Temperature Range: The DPPM16D68K-F operates across -40°C to 105°C, while the 715P682516LD3 operates across -55°C to 85°C. Circuit design must confirm that the application temperature profile falls within the substitute part's specified range.

3. Physical Dimensions: Lead spacing differs between parts (1.043" versus 0.720"). PCB layout must accommodate the substitute part's physical footprint and lead configuration.

4. Regulatory Compliance: Both parts satisfy RoHS3 and REACH requirements for regulated markets.

5. Inventory Availability: Selection between these parts may be influenced by stock availability and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the 715P682516LD3 directly replace the DPPM16D68K-F in all applications?

A: The 715P682516LD3 is electrically equivalent and mechanically compatible for through-hole radial mounting. However, the operating temperature range differs (-55°C to 85°C versus -40°C to 105°C). Verify that your application's temperature profile falls within the substitute part's limits. Additionally, confirm that PCB layout accommodates the different lead spacing (0.720" versus 1.043").

Q: What is the significance of the tolerance difference between ±10% and ±5%?

A: Tolerance defines the acceptable variation in actual capacitance value from the nominal 6800 pF specification. The ±5% tolerance of the 715P682516LD3 provides tighter capacitance accuracy, resulting in a narrower range of acceptable values. This may be beneficial in precision applications but is not required for general-purpose switching and snubber circuits.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the DPPM16D68K-F and 715P682516LD3 are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for restricted substance use in electronic components.

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

A: These represent different product series from Cornell Dubilier Electronics. The DPPM16D68K-F belongs to the DPPM series, while the 715P682516LD3 belongs to the Orange Drop® 715P series. Both series use polypropylene dielectric material and are rated for identical electrical specifications (6800 pF, 1.6 kV DC, 500V AC).

Q: How do the physical dimensions affect PCB design?

A: The DPPM16D68K-F has a lead spacing of 1.043" (26.50mm), while the 715P682516LD3 has a lead spacing of 0.720" (18.30mm). PCB hole patterns and component placement must be verified to accommodate the substitute part's lead configuration. The radial package type remains consistent between both parts.

Q: Can I use the 715P682516LD3 in high-temperature applications above 85°C?

A: No. The 715P682516LD3 is rated for operation up to 85°C maximum. Applications requiring operation above 85°C must use the DPPM16D68K-F, which is rated to 105°C, or select an alternative component with appropriate temperature rating.

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

A: Yes. Both the DPPM16D68K-F and 715P682516LD3 are specified for high-frequency switching, high-pulse, DV/DT, and snubber applications. The polypropylene metallized dielectric material in both parts provides the electrical characteristics required for these application classes.
