DPFF2S33J-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPFF2S33J-F is a 0.033 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. The part maintains Active product status with 723 units in current inventory stock.

Substitute parts are identified when equivalent capacitance and tolerance values are maintained while voltage ratings, physical dimensions, or series designations differ. Alternative selections become necessary when application requirements demand higher voltage ratings, different thermal operating ranges, or specific packaging configurations not available in the primary part number.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the DPFF2S33J-F is based on the following mandatory criteria:

Fixed Parameters (Non-Negotiable):

• Capacitance: 0.033 µF
• Tolerance: ±5%
• Dielectric Material: Polypropylene (PP), Metallized
• Mounting Type: Through Hole
• Lead Spacing: 0.374" (9.50mm)
• RoHS Compliance: ROHS3 Compliant

Variable Parameters (Acceptable Differences):

• Voltage Rating - DC: Equal or higher than 250V
• Physical dimensions and package form factor
• Operating temperature range
• Series designation and packaging type
• Specific application classifications

The substitute part 715P33354KD3 maintains all fixed parameters while offering a higher 400V DC rating and different physical dimensions. This substitution is valid for applications where the higher voltage rating does not create design conflicts and where the larger form factor is accommodated by the PCB layout.

Parameter Comparison

Engineering Selection Recommendations

DPFF2S33J-F Selection Criteria:

• Applications requiring compact radial form factor (19.10mm x 10.70mm)
• PCB designs with height constraints below 10.70mm
• Operating environments up to 105°C continuous temperature
• 250V DC rated applications with no requirement for higher voltage margin
• ROHS3 compliance required

715P33354KD3 Selection Criteria:

• Applications benefiting from 400V DC voltage rating for design margin
• PCB layouts accommodating taller component height (17.60mm maximum seated height)
• Operating environments with maximum temperature requirement of 85°C or below
• High pulse and DV/DT applications requiring Orange Drop® series performance characteristics
• ROHS3 compliance required

Substitution Validity: Both parts are ROHS3 compliant, Active status products from the same manufacturer. The 715P33354KD3 substitute is electrically valid for any application originally specified for the DPFF2S33J-F, provided that:

1. PCB layout accommodates the larger physical dimensions
2. Operating temperature does not exceed 85°C
3. The higher 400V DC rating does not create design conflicts

Frequently Asked Questions (FAQ)

Q: Can the 715P33354KD3 be used as a direct replacement for the DPFF2S33J-F?

A: The 715P33354KD3 is electrically compatible as a substitute. Both parts share identical capacitance (0.033 µF), tolerance (±5%), dielectric material (polypropylene metallized), mounting type (through hole), and lead spacing (0.374"). The substitute has a higher voltage rating (400V vs. 250V) and identical RoHS3 compliance. Physical dimensions differ; verify PCB space availability before substitution.

Q: What are the physical dimension differences between these parts?

A: The DPFF2S33J-F measures 19.10mm length x 10.70mm width with maximum seated height of 10.70mm. The 715P33354KD3 measures 9.70mm diameter x 22.90mm length with maximum seated height of 17.60mm. The substitute is taller and uses a cylindrical form factor versus the rectangular form factor of the primary part. PCB clearance verification is required.

Q: Are the lead spacings identical?

A: Yes. Both the DPFF2S33J-F and 715P33354KD3 have identical lead spacing of 0.374" (9.50mm). PCB hole patterns designed for either part are compatible.

Q: What is the temperature operating range difference?

A: The DPFF2S33J-F operates from -55°C to 105°C. The 715P33354KD3 operates from -55°C to 85°C. Applications requiring continuous operation above 85°C must use the DPFF2S33J-F or verify that the 715P33354KD3 application profile remains within the 85°C maximum.

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

A: The 715P33354KD3 is rated for 400V DC versus the DPFF2S33J-F at 250V DC. Higher voltage ratings in film capacitors typically result from different dielectric thickness or material formulation. Both parts maintain identical capacitance and tolerance values. The higher rating provides additional voltage margin in applications but does not affect electrical performance at the original 250V specification.

Q: Are both parts currently in stock?

A: The DPFF2S33J-F has 723 units in current inventory. The 715P33354KD3 has 4034 units in current inventory. Both parts maintain Active product status.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the DPFF2S33J-F and 715P33354KD3 are ROHS3 compliant. Both are REACH unaffected and classified under ECCN EAR99.
