DPFF2P12J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPFF2P12J-F is a 0.12 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 250V DC operation with polypropylene metallized dielectric. This radial through-hole component is designed for high pulse and DV/DT applications, operating across a temperature range of -55°C to 105°C. The part maintains Active product status with 757 units in current inventory stock.

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter tolerances for the application, accounting for differences in capacitance value, voltage rating, and physical dimensions while maintaining compatibility with the mounting interface and environmental specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPFF2P12J-F is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Dielectric Material: Polypropylene (PP), Metallized
• Mounting Type: Through Hole
• Package Type: Radial
• Lead Spacing: 0.720" (18.30mm)
• Termination: PC Pins
• RoHS Compliance: ROHS3 Compliant

Allowable Parameter Variations:

• Capacitance: Within ±5% tolerance band or adjacent standard values
• Voltage Rating - DC: Equal to or greater than 250V
• Voltage Rating - AC: Equal to or greater than 155V
• Operating Temperature Range: Must encompass or exceed -55°C to 105°C
• Physical Dimensions: Variations acceptable if lead spacing and termination remain constant

The substitute part 715P10454LD3 is identified based on matching dielectric material, mounting configuration, lead spacing, and termination type. Differences in capacitance value (0.1 µF vs. 0.12 µF) and voltage rating (400V DC vs. 250V DC) represent trade-offs that may be acceptable depending on circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

DPFF2P12J-F Primary Selection: The DPFF2P12J-F remains the primary component choice when the specified capacitance of 0.12 µF and operating temperature range of -55°C to 105°C are circuit requirements. This part is Active in product status with established supply availability (757 units in stock). Full ROHS3 compliance and REACH Unaffected status confirm regulatory alignment for current manufacturing standards.

715P10454LD3 Substitute Consideration: The 715P10454LD3 (Orange Drop® 715P series) provides substitution capability when circuit design tolerates a capacitance reduction to 0.1 µF and maximum operating temperature limitation to 85°C. The higher DC voltage rating of 400V offers design margin above the 250V requirement. This part demonstrates Active product status with higher inventory availability (2701 units in stock). ROHS3 compliance and REACH Unaffected status maintain regulatory requirements.

Selection Constraints:

• Substitution of 715P10454LD3 is not suitable for applications requiring sustained operation above 85°C
• The 0.1 µF capacitance of the substitute represents an 16.7% reduction from the 0.12 µF specification
• Both parts share identical lead spacing (0.720") and PC pin termination, ensuring PCB footprint compatibility

Frequently Asked Questions (FAQ)

Q: Can the 715P10454LD3 be used as a direct replacement for the DPFF2P12J-F?

A: The 715P10454LD3 shares the same lead spacing (0.720"), termination type (PC Pins), mounting configuration (Through Hole Radial), and dielectric material (Polypropylene Metallized). Physical footprint compatibility is confirmed. However, the capacitance differs (0.1 µF vs. 0.12 µF) and the maximum operating temperature is reduced (85°C vs. 105°C). Substitution is valid only when circuit design accommodates these parameter differences.

Q: What is the capacitance difference between these parts?

A: The DPFF2P12J-F is rated at 0.12 µF while the 715P10454LD3 is rated at 0.1 µF. This represents a 0.02 µF reduction or 16.7% lower capacitance. Both parts maintain ±5% tolerance. Circuit analysis is required to determine if this capacitance reduction affects performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the DPFF2P12J-F and 715P10454LD3 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the lead spacing for these capacitors?

A: Both parts feature identical lead spacing of 0.720" (18.30mm), confirming PCB footprint compatibility and eliminating the need for board redesign during substitution.

Q: How do the voltage ratings compare?

A: The DPFF2P12J-F is rated for 250V DC / 155V AC. The 715P10454LD3 is rated for 400V DC / 200V AC. The substitute provides higher voltage margin. Selection depends on circuit voltage requirements; the higher rating of the substitute does not create incompatibility.

Q: What is the operating temperature difference?

A: The DPFF2P12J-F operates from -55°C to 105°C. The 715P10454LD3 operates from -55°C to 85°C. The substitute has a 20°C lower maximum temperature limit. Applications requiring sustained operation above 85°C must use the DPFF2P12J-F.

Q: Are these parts available in different packaging options?

A: The DPFF2P12J-F is specified with standard packaging. The 715P10454LD3 is available in Bulk packaging. Both are through-hole radial components with PC pin termination. Packaging designation does not affect electrical or mechanical compatibility.
