DPFF2S12J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPFF2S12J-F is a 0.012 µF polypropylene film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 250V DC operation. This radial through-hole component is designed for high pulse and DV/DT applications requiring stable capacitance and low dissipation factor across its operating temperature range of -55°C to 105°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits selection from qualified alternatives meeting the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPFF2S12J-F is evaluated based on strict electrical and mechanical compatibility criteria. The primary substitute identified is the 715P10354JD3 from Cornell Dubilier Electronics (CDE Orange Drop® 715P series).

Substitution Logic:

The 715P10354JD3 qualifies as a substitute based on the following allowed parameters:

• Dielectric Material: Both parts use Polypropylene (PP), Metallized construction, ensuring equivalent electrical performance characteristics
• Mounting Type: Both are Through Hole radial components with PC pin termination
• Lead Spacing: 0.375 inches (9.52 mm) on the substitute versus 0.374 inches (9.50 mm) on the main part—within standard PCB hole tolerance
• Tolerance: Both maintain ±5% capacitance tolerance
• Compliance: Both are ROHS3 compliant and REACH unaffected
• Manufacturer: Both are manufactured by Cornell Dubilier Electronics, ensuring consistent quality and reliability standards

Critical Parameter Differences:

The following parameters differ between the main part and substitute and must be evaluated for circuit compatibility:

• Capacitance: 0.012 µF (main) versus 10000 pF / 0.010 µF (substitute)—represents a 16.7% reduction
• Voltage Rating (DC): 250V (main) versus 400V (substitute)—substitute provides higher voltage margin
• Voltage Rating (AC): 155V (main) versus 200V (substitute)—substitute provides higher AC rating
• Operating Temperature Range: -55°C to 105°C (main) versus -55°C to 85°C (substitute)—main part supports higher maximum temperature
• Physical Dimensions: 0.752" L x 0.370" W (main) versus 0.299" Dia x 0.701" L (substitute)—different form factors

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The 715P10354JD3 can function as a substitute for the DPFF2S12J-F in applications where the following conditions are met:

1. Capacitance Tolerance: The circuit design must accommodate a 16.7% reduction in capacitance (from 12000 pF to 10000 pF). This affects frequency response, filtering characteristics, and timing-dependent functions.

2. Temperature Operating Range: If the application requires operation above 85°C, the substitute part is not suitable. The main part DPFF2S12J-F supports continuous operation to 105°C.

3. Voltage Margin: The substitute part provides superior voltage rating margin (400V DC versus 250V DC), making it suitable for circuits operating at or below 250V DC.

4. Physical Space: PCB layout must accommodate the different form factor. The substitute is cylindrical (0.299" diameter x 0.701" length) versus the main part's rectangular profile (0.752" L x 0.370" W).

5. Compliance Requirements: Both parts maintain identical ROHS3 and REACH compliance status, suitable for regulated applications.

Selection Criteria:

• Select DPFF2S12J-F when exact 0.012 µF capacitance is required or when operating temperatures exceed 85°C
• Select 715P10354JD3 when 0.010 µF capacitance is acceptable and higher voltage rating margin is beneficial

Frequently Asked Questions (FAQ)

Q: Can the 715P10354JD3 directly replace the DPFF2S12J-F without circuit modification?

A: Direct replacement is not recommended without circuit analysis. The 16.7% capacitance difference (10000 pF versus 12000 pF) affects circuit performance in frequency-dependent applications. PCB layout changes may also be required due to different physical dimensions.

Q: What is the impact of the capacitance difference on circuit performance?

A: In filtering applications, the lower capacitance of the substitute reduces the cutoff frequency. In timing circuits, it extends time constants. In resonant circuits, it shifts resonant frequency. Circuit simulation or testing is necessary to determine acceptability for specific applications.

Q: Are the lead spacings compatible with the same PCB footprint?

A: Lead spacing differs by 0.001 inches (0.02 mm): 0.374 inches (main) versus 0.375 inches (substitute). This falls within standard PCB manufacturing tolerance (±0.005 inches) and is compatible with standard 0.375-inch radial component footprints.

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

A: The 715P10354JD3 is rated for 400V DC and 200V AC, compared to the main part's 250V DC and 155V AC. Higher voltage ratings reflect the design specifications of the Orange Drop® 715P series and do not indicate superior performance at lower voltages.

Q: Is the operating temperature range difference significant?

A: Yes. The main part DPFF2S12J-F operates to 105°C maximum, while the substitute operates to 85°C maximum. Applications requiring sustained operation above 85°C must use the main part. The lower maximum temperature of the substitute may also affect reliability in high-temperature environments.

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

A: The main part DPFF2S12J-F is specified for high pulse and DV/DT applications. The substitute 715P10354JD3 is specified for audio, high frequency, switching, high pulse, DV/DT, and snubber applications. Both support pulse and transient voltage applications.

Q: What is the inventory status for each part?

A: DPFF2S12J-F: 717 pieces in stock. 715P10354JD3: 1031 pieces in stock. Both are available as new original components.
