DME2P22K-F

Part Overview

The DME2P22K-F is a 0.22 µF polyester film capacitor with a ±10% tolerance rating and 250V DC voltage specification, manufactured by Cornell Dubilier Electronics (CDE). This component is rated for general-purpose applications with an operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and is suitable for through-hole radial mounting on printed circuit boards.

Equivalent and substitute parts are necessary to accommodate supply chain variations, alternative sourcing requirements, and design flexibility when the primary part number becomes unavailable or when performance upgrades are desired.

Parameter Comparison

Engineering Selection Recommendations

DME2P22K-F (Primary Part): Active product status with ROHS3 compliance and general-purpose application rating. Suitable for standard commercial applications without automotive qualification requirements.

160224K250F-F (CDE Alternative): Active status with ROHS3 compliance. This substitute maintains all electrical specifications with a slightly reduced operating temperature upper limit of 105°C compared to the primary part. Larger physical dimensions and increased lead spacing (15.00mm versus 10.00mm) necessitate layout verification to ensure PCB compatibility.

DMM2P22K-F (CDE Alternative): Active status with ROHS3 compliance. Maintains full electrical equivalence with identical operating temperature range to the primary part. Larger physical envelope and 15.00mm lead spacing require PCB layout evaluation.

B32521C3224K000 (EPCOS/TDK Electronics, ±10% Tolerance): Active status with ROHS3 compliance and AEC-Q200 automotive qualification. Employs polyethylene terephthalate (PET) stacked metallized construction. Equivalent lead spacing (10.00mm) to the primary part. Suitable for applications requiring automotive-grade reliability.

B32521C3224J000 (EPCOS/TDK Electronics, ±5% Tolerance, Upgrade): Active status with ROHS3 compliance and AEC-Q200 automotive qualification. Identical electrical specifications to B32521C3224K000 with improved tolerance grade of ±5%, providing higher capacitance accuracy. Equivalent lead spacing (10.00mm). Represents an upgrade option for applications requiring tighter tolerance performance.

Frequently Asked Questions (FAQ)

Q: Can I directly replace DME2P22K-F with 160224K250F-F?

A: Electrical substitution is valid. However, this part has different physical dimensions (18.00mm L x 5.00mm W versus 12.50mm L x 6.00mm W) and increased lead spacing (15.00mm versus 10.00mm). PCB layout compatibility must be verified before design implementation.

Q: What is the difference between B32521C3224K000 and B32521C3224J000?

A: Both parts maintain identical electrical ratings, operating temperature range, and lead spacing. The primary difference is tolerance grade: B32521C3224K000 offers ±10% tolerance, while B32521C3224J000 provides ±5% tolerance for improved capacitance accuracy. The ±5% version is suitable for applications with stricter capacitance tolerances.

Q: Are the EPCOS/TDK parts compatible with general-purpose applications?

A: Yes. Both B32521C3224K000 and B32521C3224J000 are qualified for automotive applications under AEC-Q200 and are suitable for general-purpose use. The stacked metallized PET construction maintains functional equivalence to the CDE polyester metallized designs.

Q: Which substitute part has identical physical dimensions to the primary DME2P22K-F?

A: B32521C3224K000 and B32521C3224J000 provide the closest physical compatibility with dimensions of 13.00mm L x 5.00mm W and matching 10.00mm lead spacing to the primary part.

Q: Why would the operating temperature reduction from 125°C to 105°C in 160224K250F-F matter?

A: Operating temperature range affects part reliability in high-temperature environments. If your application requires sustained operation above 105°C, this substitute is not suitable. Verify your application's maximum operating temperature before selection.
