DPFF2P33J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPFF2P33J-F is a 0.33 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 1094 units in current inventory stock.

Substitute parts are identified when equivalent electrical performance can be achieved while maintaining compatibility with circuit requirements and mechanical constraints. Alternative models may be necessary due to inventory availability, application-specific voltage requirements, or design optimization needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPFF2P33J-F is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value must match: 0.33 µF
• Tolerance must be equal or tighter: ±5%
• Voltage rating must equal or exceed circuit requirements: minimum 250V DC
• Dielectric material must be polypropylene metallized to maintain electrical characteristics

Mechanical Compatibility Criteria:

• Mounting type must be Through Hole
• Package configuration must be Radial
• Lead spacing must be 1.094" (27.80mm) to ensure PCB footprint compatibility
• Termination must be PC Pins

Compliance & Environmental Criteria:

• RoHS3 compliance required
• Operating temperature range must support application needs

The substitute part 715P33454MD3 meets all electrical equivalence criteria with identical capacitance, tolerance, dielectric material, and lead spacing. It provides higher voltage rating (400V DC) and maintains mechanical compatibility through identical radial configuration and PC pin termination.

Engineering Selection Recommendations

Primary Part: DPFF2P33J-F

Select the DPFF2P33J-F when the application operates at or below 250V DC with maximum ambient temperatures not exceeding 105°C. This part is Active status with robust inventory availability (1094 units). Both ROHS3 compliance and REACH unaffected status confirm regulatory alignment for current manufacturing standards.

Substitute Part: 715P33454MD3

The 715P33454MD3 serves as a direct electrical substitute with enhanced voltage rating (400V DC / 200V AC). This higher voltage rating provides additional safety margin in circuits operating below 250V DC. Mechanical compatibility is confirmed through identical lead spacing (27.80mm) and radial through-hole configuration.

Critical Selection Factor:

The operating temperature upper limit differs between parts. The DPFF2P33J-F supports continuous operation to 105°C, while the 715P33454MD3 is rated to 85°C maximum. Applications requiring sustained operation above 85°C must use the DPFF2P33J-F. Applications with maximum ambient temperatures at or below 85°C may use either part based on voltage margin requirements.

Both parts maintain Active product status and full regulatory compliance (ROHS3, REACH unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can the 715P33454MD3 replace the DPFF2P33J-F in all applications?

A: The 715P33454MD3 is electrically compatible for circuits operating at or below 250V DC and ambient temperatures not exceeding 85°C. Applications requiring operation above 85°C must use the DPFF2P33J-F due to its 105°C temperature rating.

Q: What is the significance of the higher voltage rating on the 715P33454MD3?

A: The 400V DC rating on the 715P33454MD3 provides increased voltage margin compared to the 250V DC rating of the DPFF2P33J-F. Both parts function identically in circuits designed for 250V DC operation. The higher rating does not affect capacitance, tolerance, or electrical performance.

Q: Are the physical dimensions compatible for PCB mounting?

A: Yes. Both parts share identical lead spacing of 1.094" (27.80mm) and radial through-hole configuration. PCB footprints designed for the DPFF2P33J-F accommodate the 715P33454MD3 without modification. Physical case dimensions differ slightly, but this does not affect electrical or mechanical compatibility.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the DPFF2P33J-F and 715P33454MD3 are ROHS3 compliant and REACH unaffected. Both carry EAR99 classification and are manufactured by Cornell Dubilier Electronics under Active product status.

Q: What is the difference between the DPFF and Orange Drop® 715P series?

A: These are distinct product series from the same manufacturer. Both use polypropylene metallized dielectric and share identical electrical specifications for the 0.33 µF / ±5% / 27.80mm lead spacing configuration. Series designation reflects different product lines within the CDE portfolio.

Q: Can I use the 715P33454MD3 in high-temperature applications?

A: The 715P33454MD3 is rated for continuous operation to 85°C maximum. Applications requiring sustained operation above 85°C require the DPFF2P33J-F, which is rated to 105°C.
