Substitute Part Grouping Explanation

Substitution of the DPFF12D68J-F is permissible when the alternative part maintains the following critical parameters:

Electrical Equivalence Requirements:

Capacitance value: 6800 pF (±5% tolerance maintained)
Dielectric material: Polypropylene (PP), Metallized
Voltage rating: Equal to or greater than 1200 V DC and 475 V AC

Mechanical Compatibility Requirements:

Mounting type: Through Hole
Package type: Radial
Lead spacing: 0.720 inches (18.30 mm)
Termination: PC Pins

Compliance Requirements:

RoHS3 Compliant status
REACH Unaffected status
Active product status

The substitute part 715P682516LD3 meets all electrical equivalence and mechanical compatibility criteria. The higher voltage rating (1600 V DC, 500 V AC) provides additional safety margin. Lead spacing and termination type are identical, ensuring direct board-level compatibility.

Engineering Selection Recommendations

Primary Part Selection (DPFF12D68J-F): The DPFF12D68J-F is the specified component and should be used when available. It is ROHS3 compliant, REACH unaffected, and actively manufactured. The operating temperature range extends to 105°C, supporting applications requiring elevated temperature performance.

Substitute Part Selection (715P682516LD3): The 715P682516LD3 (Orange Drop® 715P series) is a direct electrical and mechanical substitute. Both parts are manufactured by CDE and share identical capacitance, tolerance, lead spacing, and termination specifications. The substitute part carries higher voltage ratings (1600 V DC, 500 V AC), providing additional design margin in high-voltage applications. Both parts maintain ROHS3 compliance and REACH unaffected status.

Application-Specific Considerations: For applications operating continuously above 85°C, the DPFF12D68J-F is required due to its 105°C maximum operating temperature rating. For applications operating at or below 85°C, either part is suitable. The substitute part's higher voltage rating makes it appropriate for circuits where voltage stress margins are critical.

Frequently Asked Questions (FAQ)

Q: Can 715P682516LD3 be used as a direct replacement for DPFF12D68J-F on existing PCBs?

A: Yes. Both parts have identical lead spacing (0.720 inches / 18.30 mm), radial package configuration, and PC pin termination. Physical board-level compatibility is confirmed.

Q: What is the difference in physical dimensions between these parts?

A: The DPFF12D68J-F measures 1.299" L x 0.551" W with a seated height of 0.551". The 715P682516LD3 measures 0.520" Dia x 1.252" L with a seated height of 0.811". The substitute part is taller and has a different cylindrical form factor. Verify clearance in the application before substitution.

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

A: The DPFF12D68J-F is specified for high pulse and DV/DT applications. The 715P682516LD3 is specified for audio, high frequency, switching, high pulse, DV/DT, and snubber applications. Both parts support high-pulse operation.

Q: What is the temperature operating range difference?

A: The DPFF12D68J-F operates from -55°C to 105°C. The 715P682516LD3 operates from -55°C to 85°C. For applications requiring operation above 85°C, the DPFF12D68J-F is required.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the DPFF12D68J-F and 715P682516LD3 are ROHS3 compliant and REACH unaffected. Both parts are actively manufactured and meet current environmental regulations.

Q: Why does the substitute part have a higher voltage rating?

A: The 715P682516LD3 is rated for 1600 V DC and 500 V AC, compared to the DPFF12D68J-F at 1200 V DC and 475 V AC. Higher voltage ratings indicate different internal construction and materials. The substitute part provides additional voltage stress margin in high-voltage circuit designs.
