DPFF2P18J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPFF2P18J-F is a 0.18 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 911 units in current inventory stock.

Substitute parts are identified when equivalent electrical performance can be achieved within the allowed parameter tolerances for the application category, accounting for variations in capacitance value, voltage rating, and physical dimensions while maintaining compatible mounting and termination characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPFF2P18J-F is determined by the following criteria:

Electrical Compatibility Parameters:

• Dielectric material must be Polypropylene (PP), Metallized
• Voltage rating must equal or exceed the application requirement (minimum 250V DC)
• Capacitance value must fall within the tolerance band or provide functional equivalence for the circuit
• Tolerance specification must be ±5% or tighter

Mechanical Compatibility Parameters:

• Mounting type must be Through Hole
• Package configuration must be Radial
• Lead spacing must be 0.720" (18.30mm) to ensure PCB compatibility
• Termination must be PC Pins

Compliance Parameters:

• RoHS3 Compliant status required
• REACH Unaffected classification required

The substitute part 715P15454LD3 meets these criteria with the following considerations: capacitance is 0.15 µF (within functional range for many applications), voltage rating is elevated to 400V DC (exceeding minimum requirement), dielectric material is identical, mounting and termination are compatible, and compliance certifications are maintained.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (DPFF2P18J-F): Select the DPFF2P18J-F when the application requires the specified 0.18 µF capacitance value, 250V DC rating, and extended operating temperature range to 105°C. This part is Active status with established inventory availability (911 units in stock). ROHS3 compliance and REACH Unaffected status confirm regulatory alignment for current manufacturing standards.

Substitute Part Selection (715P15454LD3): The 715P15454LD3 (Orange Drop® 715P series) serves as a functional substitute when circuit design permits a 0.15 µF capacitance value and the application operates within the -55°C to 85°C temperature range. The elevated 400V DC voltage rating provides additional safety margin in voltage-constrained applications. This part is Active status with 872 units in current inventory. ROHS3 compliance and REACH Unaffected status maintain regulatory requirements.

Substitution Constraints:

• Do not substitute if the application requires operation above 85°C
• Do not substitute if the circuit design requires the exact 0.18 µF capacitance value without tolerance adjustment
• Both parts maintain identical lead spacing (0.720"), enabling direct PCB footprint compatibility
• Both parts are manufactured by Cornell Dubilier Electronics, ensuring consistent quality standards and reliability characteristics

Frequently Asked Questions (FAQ)

Q: Can the 715P15454LD3 directly replace the DPFF2P18J-F on the PCB?

A: Yes, regarding physical installation. Both parts feature 0.720" (18.30mm) lead spacing, radial package configuration, and PC pin termination. However, the 0.15 µF capacitance value differs from the 0.18 µF specification. Verify that the circuit design tolerates this 16.7% capacitance reduction before substitution.

Q: What is the primary difference in electrical ratings between these parts?

A: The DPFF2P18J-F is rated 250V DC / 155V AC, while the 715P15454LD3 is rated 400V DC / 200V AC. The substitute part has higher voltage ratings, making it suitable for applications operating at or below the original part's voltage specification. The DPFF2P18J-F supports operation to 105°C, while the 715P15454LD3 maximum operating temperature is 85°C.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the DPFF2P18J-F and 715P15454LD3 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What applications are these capacitors designed for?

A: The DPFF2P18J-F is specified for high pulse and DV/DT applications. The 715P15454LD3 (Orange Drop® series) is rated for audio, high frequency, switching, high pulse, DV/DT, and snubber applications. Both utilize polypropylene metallized dielectric suitable for these demanding circuit conditions.

Q: If my application requires 0.18 µF exactly, can I use the 715P15454LD3?

A: No. The 715P15454LD3 provides 0.15 µF capacitance. While both parts carry ±5% tolerance, the nominal values differ. Use the DPFF2P18J-F if the circuit design requires the 0.18 µF specification.

Q: What is the inventory status for both parts?

A: The DPFF2P18J-F has 911 units in stock. The 715P15454LD3 has 872 units in stock. Both are Active products with current availability.
