DPP6S22K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPP6S22K-F is a 0.022 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPP series. This radial through-hole component operates at 630V DC with polypropylene metallized dielectric construction. The part is currently active in production with 982 units in stock. Film capacitors of this specification are essential in high-frequency and switching applications where low ESR performance and stable capacitance across temperature ranges are required. Substitute parts may be necessary due to supply constraints, lead time requirements, or inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPP6S22K-F is determined by the following criteria:

Critical Parameters (Must Match):

• Capacitance value: 0.022 µF
• Dielectric type: Polypropylene (PP), Metallized
• Mounting configuration: Through Hole Radial
• DC voltage rating: 630V minimum
• Tolerance: ±10% or tighter

Acceptable Variation Parameters:

• AC voltage rating: May differ from 250V if DC rating is maintained
• Physical dimensions: May vary within PCB layout constraints
• Lead spacing: May differ if through-hole compatibility is maintained
• Operating temperature range: Substitute must not have a narrower range than -55°C ~ 105°C
• Regulatory compliance: Must maintain ROHS3 compliance

The QXT2J223KRPT from Nichicon meets all critical substitution criteria while maintaining equivalent electrical performance for high-frequency and switching applications.

Engineering Selection Recommendations

DPP6S22K-F (Primary Selection): The DPP6S22K-F remains the primary component choice when the specified operating temperature range of -55°C ~ 105°C is required and PCB layout accommodates the 20.00mm lead spacing. This part is active in production with established supply availability (982 units in stock).

QXT2J223KRPT (Substitute Selection): The QXT2J223KRPT is a valid substitute when the following conditions are met:

• Operating temperature requirements do not extend below -40°C
• PCB layout can accommodate 15.00mm lead spacing
• Smaller physical footprint (19.00mm L x 9.30mm W) is compatible with board design
• Higher AC voltage rating (300V vs. 250V) provides additional margin

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory consistency. The substitute part offers superior AC voltage performance and reduced board space requirements at the trade-off of a narrower low-temperature operating range.

Frequently Asked Questions (FAQ)

Q: Can QXT2J223KRPT replace DPP6S22K-F in all applications?

A: The QXT2J223KRPT is electrically equivalent for capacitance, DC voltage, tolerance, and dielectric type. However, substitution requires verification that the operating temperature range of -40°C ~ 105°C (versus -55°C ~ 105°C) is acceptable for the application. Additionally, the different lead spacing (15.00mm vs. 20.00mm) requires PCB layout compatibility confirmation.

Q: What is the impact of different lead spacing?

A: Lead spacing determines the distance between through-hole mounting points on the PCB. The DPP6S22K-F uses 20.00mm spacing while the QXT2J223KRPT uses 15.00mm spacing. Direct substitution on existing PCBs designed for 20.00mm spacing is not possible without board redesign. New designs can accommodate either spacing based on layout requirements.

Q: Are there any performance differences between these parts?

A: Both parts use identical polypropylene metallized dielectric construction and maintain the same capacitance and DC voltage rating. The QXT2J223KRPT provides higher AC voltage rating (300V vs. 250V). The DPP6S22K-F supports a wider low-temperature operating range (-55°C vs. -40°C minimum).

Q: What compliance certifications apply to both parts?

A: Both the DPP6S22K-F and QXT2J223KRPT are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification for export purposes.

Q: Which part should be selected for new designs?

A: For new designs, either part is acceptable based on application requirements. If extended low-temperature operation below -40°C is necessary, the DPP6S22K-F is required. If board space is constrained and operating temperature remains above -40°C, the QXT2J223KRPT offers a smaller footprint advantage.
