DPP4S22K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPP4S22K-F is a 0.022 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPP series. This radial polypropylene metallized capacitor operates at 400V DC with ±10% tolerance and is designed for high-frequency and switching applications. The part is currently active in production with 1075 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to availability constraints, design flexibility, or application-specific requirements.

Substitute Part Grouping Explanation

Substitute parts for the DPP4S22K-F are identified based on the following criteria:

Electrical Equivalence:

Capacitance value must be identical: 0.022 µF
Tolerance must be ±10% or tighter
Voltage rating must meet or exceed both AC (250V) and DC (400V) specifications
Dielectric material must be polypropylene metallized film

Mechanical Compatibility:

Mounting configuration must be through-hole radial
Lead spacing must be 0.591" (15.00mm) to ensure PCB footprint compatibility
Physical dimensions should be comparable to allow board layout flexibility

Regulatory & Environmental:

RoHS3 compliance required
REACH unaffected status maintained
Operating temperature range must support or exceed -55°C ~ 105°C

The QXT2J223KRPT from Nichicon meets all substitution criteria with enhanced voltage ratings and comparable physical characteristics.

Engineering Selection Recommendations

Primary Part - DPP4S22K-F (CDE):

Select when CDE DPP series is specified in design documentation
1075 units available for immediate procurement
Meets all application requirements with -55°C lower temperature limit
ROHS3 compliant and REACH unaffected

Substitute Part - QXT2J223KRPT (Nichicon):

Select when higher voltage margin is required (630V DC vs. 400V DC)
1255 units available for immediate procurement
Provides enhanced reliability through voltage derating capability
Slightly lower profile (18.30mm vs. 20.00mm) may improve board layout density
ROHS3 compliant and REACH unaffected
Operating temperature range covers -40°C to 105°C (lower limit differs by 15°C)

Both parts maintain identical electrical performance for the specified 0.022 µF, ±10%, 400V DC application. Selection between them depends on voltage margin requirements and thermal environment specifications.

Frequently Asked Questions (FAQ)

Q: Can QXT2J223KRPT replace DPP4S22K-F in all applications?

A: Yes, for applications operating at or below 400V DC and 250V AC. The QXT2J223KRPT exceeds these voltage ratings (630V DC, 300V AC), providing additional safety margin. Both parts have identical capacitance, tolerance, dielectric material, and lead spacing.

Q: What is the difference in physical size between these parts?

A: DPP4S22K-F measures 19.50mm L x 10.00mm W with 20.00mm seated height. QXT2J223KRPT measures 19.00mm L x 9.30mm W with 18.30mm seated height. The Nichicon part is slightly more compact, which may benefit board layout in space-constrained designs.

Q: Are both parts RoHS3 compliant?

A: Yes, both DPP4S22K-F and QXT2J223KRPT are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the operating temperature difference?

A: DPP4S22K-F operates from -55°C to 105°C. QXT2J223KRPT operates from -40°C to 105°C. The DPP4S22K-F provides 15°C additional low-temperature capability. Select based on minimum operating temperature requirements of your application.

Q: Do these parts have the same lead spacing?

A: Yes, both parts have 0.591" (15.00mm) lead spacing, ensuring identical PCB footprint compatibility and interchangeability on existing circuit boards.

Q: What does the voltage rating difference mean for circuit design?

A: The QXT2J223KRPT's higher voltage rating (630V DC vs. 400V DC) allows for greater voltage derating margin in the circuit. This can extend component life and improve reliability in applications with voltage transients or margin requirements.
