DPFF6S33J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPFF6S33J-F is a 0.033 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 630V DC operation with polypropylene metallized dielectric. This radial through-hole component is designed for high pulse and DV/DT applications. The part is currently Active in product status with 1065 pieces in stock inventory. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, procurement lead times, or design optimization needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPFF6S33J-F are identified based on strict electrical and mechanical parameter matching. The substitution logic is governed by the following criteria:

Electrical Compatibility Requirements:

• Capacitance value must be identical: 0.033 µF
• DC voltage rating must be equal to or greater than 630V
• AC voltage rating must be equal to or greater than 200V
• Tolerance must be ±5% or tighter
• Dielectric material must be polypropylene metallized film

Mechanical Compatibility Requirements:

• Mounting type must be through-hole radial configuration
• Lead spacing must be 0.720" (18.30mm) to ensure PCB footprint compatibility
• Termination must be PC pins for soldering compatibility

Regulatory & Environmental Requirements:

• RoHS3 compliance mandatory
• Operating temperature range must encompass or exceed -55°C to 105°C

The substitute part 715P33356LD3 meets the electrical and mechanical criteria with one exception: its DC voltage rating is 600V, which is 30V lower than the DPFF6S33J-F specification of 630V. This represents a voltage derating condition and affects application suitability.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Conditions:

The 715P33356LD3 is electrically and mechanically compatible with the DPFF6S33J-F for applications where the circuit design voltage margin permits operation at 600V DC instead of 630V DC. Both parts are Active products from the same manufacturer with ROHS3 compliance and identical lead spacing for PCB compatibility.

Voltage Derating Consideration:

The 30V reduction in DC voltage rating (630V to 600V) represents a 4.8% derating. This substitution is valid only when the circuit's maximum operating voltage does not exceed 600V DC. Applications specified for 630V DC operation require the original DPFF6S33J-F part.

Temperature Range Consideration:

The 715P33356LD3 has a maximum operating temperature of 85°C compared to the DPFF6S33J-F specification of 105°C. This 20°C reduction in upper temperature limit must be evaluated against the thermal environment of the application. Substitution is valid for applications where ambient and component temperatures remain below 85°C.

Packaging and Inventory:

The DPFF6S33J-F is available in 1065 pieces with standard packaging. The 715P33356LD3 is available in 1441 pieces with bulk packaging. Both parts maintain identical lead spacing and mounting footprint.

Frequently Asked Questions (FAQ)

Q: Can the 715P33356LD3 be used in place of the DPFF6S33J-F in all applications?

A: No. The 715P33356LD3 has a 600V DC rating versus the DPFF6S33J-F's 630V DC rating. Substitution is valid only when the circuit design voltage does not exceed 600V DC. Additionally, the 715P33356LD3 has a maximum operating temperature of 85°C versus 105°C for the DPFF6S33J-F, which must be considered for thermal environments.

Q: Are the physical dimensions compatible for PCB mounting?

A: Yes. Both parts have identical lead spacing of 0.720" (18.30mm) and are radial through-hole components. They share the same PCB footprint. However, the 715P33356LD3 has different overall dimensions (0.461" Dia x 1.252" L versus 1.299" L x 0.551" W for the DPFF6S33J-F), which may affect board layout clearance in confined spaces.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the DPFF6S33J-F and 715P33356LD3 are ROHS3 compliant and REACH unaffected, with identical ECCN and HTSUS classifications.

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

A: These are different product series from Cornell Dubilier Electronics. The DPFF6S33J-F belongs to the DPFF series, while the 715P33356LD3 belongs to the Orange Drop® 715P series. Both use polypropylene metallized dielectric and are rated for high pulse and DV/DT applications, but they differ in voltage rating, temperature range, and physical form factor.

Q: Can I use the 715P33356LD3 in high-temperature applications?

A: The 715P33356LD3 is rated to 85°C maximum operating temperature. If your application requires operation above 85°C, the DPFF6S33J-F with its 105°C rating is required.

Q: Are there any moisture sensitivity concerns with these parts?

A: The DPFF6S33J-F has MSL 1 (Unlimited), indicating no moisture sensitivity. The 715P33356LD3 is listed as Not Applicable for MSL, indicating it also has no moisture sensitivity concerns. Both parts can be stored and handled without special moisture control measures.
