DPP2P22K-F Equivalent & Substitute Parts Reference

Part Overview

The DPP2P22K-F is a 0.22 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPP series. This radial through-hole component operates at 250V DC with polypropylene metallized dielectric and is designed for high-frequency and switching applications. The part is currently active in production with 728 units in stock. Substitute parts are identified when equivalent capacitance and tolerance specifications are maintained while accommodating different voltage ratings, dielectric materials, or physical dimensions required by specific circuit implementations.

Substitute Part Grouping Explanation

Substitution of the DPP2P22K-F is determined by the following criteria:

Primary Matching Criteria:

• Capacitance value: 0.22 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)
• Lead spacing: 0.787 inches / 20.00 mm (exact match required)

Allowable Variation Parameters:

• Voltage rating (DC): May be equal to or greater than 250V
• Voltage rating (AC): May be equal to or greater than 140V
• Dielectric material: Polypropylene or Polyester metallized film
• Operating temperature range: May extend beyond -55°C to 105°C
• Physical dimensions: May vary within radial package constraints
• ESR characteristics: May differ based on dielectric material

The substitute part 224MSR400K meets all primary matching criteria while providing higher voltage ratings (400V DC, 200V AC) and an extended upper operating temperature limit (125°C). The dielectric material differs (Polyester vs. Polypropylene), which is permissible for equivalent capacitive performance in the specified applications.

Engineering Selection Recommendations

DPP2P22K-F Selection Criteria:

• Applications requiring polypropylene dielectric characteristics
• Circuits operating at or below 250V DC and 140V AC
• Space constraints permitting standard radial package dimensions (27.00 mm height)
• Operating environments within -55°C to 105°C range
• High-frequency and switching applications with low ESR requirements

224MSR400K Selection Criteria:

• Applications requiring higher voltage margin (400V DC, 200V AC)
• Circuits operating in elevated temperature environments up to 125°C
• Space-constrained designs benefiting from compact profile (14.50 mm height)
• Polyester dielectric performance is acceptable for the application
• General-purpose film capacitor applications

Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8532.25.0070. Both maintain unlimited moisture sensitivity level (MSL 1) and through-hole radial mounting with identical lead spacing. Selection between these parts depends on voltage requirements, temperature operating range, and available board space.

Frequently Asked Questions (FAQ)

Q: Can the 224MSR400K replace the DPP2P22K-F in all applications?

A: The 224MSR400K is electrically compatible as a substitute where the circuit voltage does not exceed 250V DC or 140V AC. The higher voltage rating of the substitute (400V DC, 200V AC) does not create incompatibility. However, the dielectric material differs (Polyester vs. Polypropylene), which may affect performance in specific high-frequency applications. Physical dimensions also differ; the substitute is more compact (14.50 mm height vs. 27.00 mm height).

Q: What is the significance of the different dielectric materials?

A: The DPP2P22K-F uses polypropylene metallized film, while the 224MSR400K uses polyester metallized film. Both are film capacitor types suitable for the specified applications. Polypropylene typically offers lower ESR and better high-frequency performance. Polyester provides higher voltage ratings and extended temperature ranges. Selection depends on whether the application prioritizes low ESR characteristics or higher voltage/temperature margins.

Q: Are the lead spacings identical?

A: Yes. Both the DPP2P22K-F and 224MSR400K have identical lead spacing of 0.787 inches (20.00 mm), ensuring direct PCB footprint compatibility.

Q: Will the smaller physical dimensions of the 224MSR400K affect circuit performance?

A: The 224MSR400K is more compact (22.50 mm x 8.00 mm vs. 26.00 mm x 14.00 mm) and lower profile (14.50 mm vs. 27.00 mm height). These dimensional differences do not affect electrical performance. The substitute may be preferred in space-constrained designs while maintaining identical lead spacing for PCB compatibility.

Q: Are both parts currently available?

A: Yes. The DPP2P22K-F has 728 units in stock, and the 224MSR400K has 5,640 units in stock, both listed as active products.

Q: What is the operating temperature difference between these parts?

A: The DPP2P22K-F operates from -55°C to 105°C. The 224MSR400K extends the upper limit to 125°C. For applications requiring operation above 105°C, the 224MSR400K is the appropriate selection.
