DPPM10D47K-F Film Capacitor - Equivalent & Substitute Parts

Part Overview

The DPPM10D47K-F is a 4700 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a rated voltage of 1000V DC and 450V AC. This polypropylene metallized radial capacitor is designed for high-frequency switching applications, high-pulse environments, and snubber circuits. The product maintains active status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative equivalent parts may be required due to inventory considerations, specific application requirements, or design optimization needs.

Substitute Part Grouping Explanation

Substitution of the DPPM10D47K-F with the R73QI14704030J (KEMET) is permissible based on the following core electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance: Both parts rated at 4700 pF (identical)
• DC Voltage Rating: Both parts rated at 1000V DC (identical)
• Dielectric Type: Both utilize Polypropylene (PP), Metallized construction (identical)
• Mounting Type: Both are Through Hole, Radial configuration (identical)
• Termination: Both use PC Pins (identical)
• RoHS Compliance: Both are ROHS3 Compliant (compatible)

Permissible Parameter Variations:

• Capacitance Tolerance: DPPM10D47K-F (±10%) to R73QI14704030J (±5%) — tighter tolerance acceptable for substitution
• AC Voltage Rating: DPPM10D47K-F (450V) to R73QI14704030J (400V) — both significantly exceed typical AC operating conditions
• Operating Temperature: DPPM10D47K-F (-40°C to 105°C) to R73QI14704030J (-55°C to 105°C) — extended low-temperature range compatible
• Physical Dimensions: Differences exist in footprint and height; verify PCB layout compatibility before substitution

Parameter Comparison

Engineering Selection Recommendations

Both the DPPM10D47K-F and R73QI14704030J maintain active product status with full ROHS3 compliance. The R73QI14704030J includes AEC-Q200 automotive qualification, providing additional assurance for applications with stringent reliability requirements. Selection between these parts depends on physical space constraints and packaging density requirements. The DPPM10D47K-F occupies a larger footprint with 0.827" (21.00mm) lead spacing, while the R73QI14704030J provides a more compact form factor with 0.591" (15.00mm) lead spacing. Both parts are suitable for high-frequency switching and high-pulse applications. The tighter tolerance of the R73QI14704030J (±5%) compared to the DPPM10D47K-F (±10%) provides improved capacitance accuracy where required.

Frequently Asked Questions (FAQ)

Q: Can the R73QI14704030J directly replace the DPPM10D47K-F without circuit modification?

A: Direct electrical substitution is permissible due to identical capacitance, voltage rating, and dielectric type. However, the different lead spacing (0.591" versus 0.827") requires PCB layout verification. Mechanical fit must be confirmed before implementation.

Q: What is the significance of the capacitance tolerance difference (±10% versus ±5%)?

A: The DPPM10D47K-F allows ±10% variance from the nominal 4700 pF value, while the R73QI14704030J restricts variance to ±5%. The tighter tolerance of the substitute part ensures more consistent performance across production batches and is compatible with the broader tolerance requirement of the original part.

Q: Are there temperature operating range implications for substitution?

A: The R73QI14704030J extends the low-temperature operating range to -55°C compared to the DPPM10D47K-F at -40°C, with both maintaining 105°C upper limit. This extended range provides additional margin for applications in cold environments without compromising performance.

Q: Does the AC voltage rating difference (450V versus 400V) affect compatibility?

A: Both ratings significantly exceed standard AC operating conditions for this capacitor class. The 450V rating of the DPPM10D47K-F provides slightly higher margin; however, 400V rating of the R73QI14704030J remains compatible for typical applications. Circuit peak AC voltage requirements must be confirmed below 400V for safe substitution.

Q: What packaging considerations apply to this substitution?

A: The R73QI14704030J features a compact radial package (18.00mm length, 5.00mm width) compared to the DPPM10D47K-F (25.00mm length, 7.50mm width). The smaller footprint of the substitute part permits greater PCB routing flexibility and reduces board space requirements. Lead spacing reduction from 21.00mm to 15.00mm requires PCB hole pattern verification.
