Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPPM16D47K is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 4700 pF (exact match required)
• Tolerance: ±10% (defines acceptable capacitance range)
• Voltage Rating - DC: 1600V minimum (safety and performance margin)
• Voltage Rating - AC: 500V minimum
• Dielectric Type: Polypropylene (PP), Metallized (electrical performance and frequency response)
• Operating Temperature Range: -40°C ~ 105°C (environmental compatibility)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Package / Case: Radial (physical form factor)
• Lead Spacing: 0.827" (21.00mm) (PCB footprint compatibility)
• Termination: PC Pins (soldering compatibility)

Only parts meeting all these parameters are considered direct substitutes. Deviations in any parameter require circuit re-evaluation and are outside the scope of direct substitution.

Parameter Comparison

Engineering Selection Recommendations

DPPM16D47K-F is the primary direct substitute for the obsolete DPPM16D47K. Both parts are manufactured by Cornell Dubilier Electronics and share identical electrical and mechanical specifications across all critical parameters. The DPPM16D47K-F is currently in active production status, ensuring long-term supply availability.

The key distinction between the main part and its substitute is regulatory compliance:

• DPPM16D47K: RoHS non-compliant
• DPPM16D47K-F: ROHS3 Compliant

For applications subject to RoHS3 regulatory requirements or environmental compliance mandates, the DPPM16D47K-F is the appropriate selection. Both parts maintain identical electrical performance, thermal characteristics, and physical form factors, enabling direct PCB-level substitution without circuit modification.

The DPPM16D47K-F is available in higher inventory (986 Pcs) compared to the obsolete part (837 Pcs), supporting production continuity and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can DPPM16D47K-F be used as a direct replacement for DPPM16D47K in existing designs?

A: Yes. The DPPM16D47K-F is a direct substitute. All electrical parameters (capacitance, voltage rating, dielectric type, temperature range) and mechanical parameters (package, lead spacing, dimensions, termination) are identical. No circuit modifications are required.

Q: What is the difference between DPPM16D47K and DPPM16D47K-F?

A: The primary difference is product status and regulatory compliance. DPPM16D47K is obsolete and RoHS non-compliant. DPPM16D47K-F is active production and ROHS3 compliant. All functional and physical specifications are equivalent.

Q: Are there any compatibility concerns with PCB footprints?

A: No. Both parts share identical lead spacing (0.827" / 21.00mm), package type (radial), and termination (PC Pins). PCB footprints designed for DPPM16D47K are fully compatible with DPPM16D47K-F.

Q: What applications are these capacitors suitable for?

A: Both parts are rated for high-frequency switching applications, high-pulse environments with high DV/DT characteristics, and snubber circuits. Operating temperature range of -40°C ~ 105°C supports industrial and commercial applications.

Q: Is RoHS3 compliance required for my application?

A: If your application or end-market requires RoHS3 compliance, DPPM16D47K-F is the appropriate selection. If RoHS compliance is not a requirement, both parts are functionally equivalent.

Q: What is the lead spacing and how does it affect PCB design?

A: Lead spacing is 0.827" (21.00mm). This dimension determines the distance between mounting holes on the PCB. Both substitute parts maintain this specification, ensuring compatibility with existing PCB layouts.

Q: Can these capacitors be used in high-voltage applications?

A: Yes. Both parts are rated for 1600V DC and 500V AC, making them suitable for high-voltage circuit applications within these voltage limits.
