Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPPM16D68K is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 6800 pF (exact match required)
• Tolerance: ±10% (defines acceptable capacitance range)
• Voltage Rating - DC: 1600V (1.6kV) minimum (no downrating permitted)
• Voltage Rating - AC: 500V (no downrating permitted)
• Dielectric Material: Polypropylene (PP), Metallized (functional requirement for application class)

Mechanical Parameters:

• Mounting Type: Through Hole (PCB assembly compatibility)
• Package / Case: Radial (form factor and board layout constraint)
• Lead Spacing: 1.043" (26.50mm) (PCB hole pattern compatibility)
• Termination: PC Pins (soldering interface standard)

Environmental Parameters:

• Operating Temperature Range: -40°C ~ 105°C (thermal operating envelope)

Substitute parts must match all parameters listed above. Deviations in any parameter disqualify a part from direct substitution.

Engineering Selection Recommendations

DPPM16D68K-F is the direct substitute for DPPM16D68K. Both parts are manufactured by Cornell Dubilier Electronics and share identical electrical, mechanical, and thermal specifications. The primary distinction is product status and regulatory compliance:

• DPPM16D68K-F is classified as Active, ensuring continued availability and manufacturer support.
• DPPM16D68K-F is ROHS3 Compliant, meeting current environmental and regulatory requirements for new designs and procurement.
• DPPM16D68K is Obsolete and RoHS non-compliant, limiting its use to legacy system maintenance where existing stock is available.

For new designs, procurement of replacement units, or systems requiring regulatory compliance, DPPM16D68K-F is the appropriate selection. Both parts are electrically and mechanically interchangeable without circuit modification or PCB redesign.

715P682516LD3 is listed as a cross-reference part number. Complete technical specifications for this part number are not provided in the available data. Verification of electrical, mechanical, and thermal parameters against the DPPM16D68K specification is required before implementation.

Frequently Asked Questions (FAQ)

Q: Can DPPM16D68K-F be used as a direct replacement for DPPM16D68K in existing assemblies?

A: Yes. DPPM16D68K-F is electrically and mechanically identical to DPPM16D68K. All electrical parameters (capacitance, voltage ratings, tolerance, dielectric material) and mechanical parameters (package, lead spacing, dimensions, termination) are equivalent. No circuit modification or PCB rework is required.

Q: What is the difference between DPPM16D68K and DPPM16D68K-F?

A: The parts are functionally equivalent. DPPM16D68K-F is the active production variant with ROHS3 compliance, while DPPM16D68K is obsolete and RoHS non-compliant. DPPM16D68K-F is recommended for all new procurement and design implementations.

Q: Are there any physical differences between DPPM16D68K and DPPM16D68K-F?

A: No. Both parts share identical dimensions (1.220" L x 0.413" W, 31.00mm x 10.50mm), lead spacing (1.043" / 26.50mm), and maximum seated height (0.807" / 20.50mm). PCB layout and assembly tooling require no modification.

Q: What does the "-F" suffix in DPPM16D68K-F indicate?

A: The "-F" suffix indicates the active production variant with updated regulatory compliance (ROHS3). The core part number DPPM16D68K remains unchanged, indicating functional equivalence.

Q: Can DPPM16D68K be used in new designs?

A: DPPM16D68K is classified as obsolete and RoHS non-compliant. For new designs, DPPM16D68K-F is the appropriate selection. Use of obsolete parts in new designs may create supply chain risk and regulatory compliance issues.

Q: What is the voltage derating requirement for these capacitors?

A: The specified voltage ratings are 1600V DC and 500V AC. These are the maximum operating voltages. Circuit design must not exceed these ratings. No derating information is provided in the component specifications.

Q: Are DPPM16D68K and DPPM16D68K-F suitable for high-frequency switching applications?

A: Yes. Both parts are specified for high-frequency switching, high-pulse, DV/DT, and snubber applications. The polypropylene metallized dielectric is appropriate for these application classes.

Q: What is the lead spacing tolerance for PCB hole pattern design?

A: The specified lead spacing is 1.043" (26.50mm). PCB design must accommodate this spacing. Tolerance information for lead spacing is not provided in the component specifications.

Q: Is moisture sensitivity a concern for these capacitors?

A: Both DPPM16D68K and DPPM16D68K-F are classified as Moisture Sensitivity Level (MSL) 1 (Unlimited). No moisture sensitivity precautions are required during storage, handling, or assembly.
