DPM2W2P2K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPM2W2P2K-F is a 2.2 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPM series. This radial through-hole component operates at 250V DC with polypropylene metallized dielectric construction. The part is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Film capacitors of this specification are essential in DC link filtering, DC filtering applications, and high-frequency switching circuits where low ESR and low ESL characteristics are required. Equivalent and substitute parts are identified to provide design flexibility, inventory alternatives, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPM2W2P2K-F are identified based on strict electrical and mechanical parameter alignment. The substitution logic requires:

Critical Matching Parameters:

• Capacitance value: 2.2 µF (exact match)
• Voltage rating (DC): 250V minimum
• Tolerance: ±10%
• Dielectric type: Polypropylene (PP), Metallized
• Mounting configuration: Through Hole, Radial
• Lead spacing: 1.083" (27.50mm)
• Operating temperature range: -55°C ~ 105°C minimum

Acceptable Variation Parameters:

• Physical dimensions (length, width, height) may vary within mechanical envelope constraints
• AC voltage rating may exceed 160V specification
• Series designation may differ (DPM vs. MPR)
• Packaging format (Bulk vs. standard)

The substitute part 225MPR250K meets all critical matching parameters and is therefore classified as a direct equivalent for circuit design purposes.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (DPM2W2P2K-F): Select the DPM2W2P2K-F when the original design specification requires the exact physical envelope dimensions (1.260" L x 1.063" H). This part maintains full compatibility with existing PCB layouts and mechanical constraints. Active product status ensures continued availability and supply chain stability.

Substitute Selection (225MPR250K): The 225MPR250K is electrically and functionally equivalent to the DPM2W2P2K-F for all circuit design purposes. This substitute is suitable when:

• PCB layout accommodates the lower profile form factor (0.827" H vs. 1.063" H)
• Slightly reduced length (1.220" vs. 1.260") does not conflict with mechanical placement
• Higher AC voltage rating (200V vs. 160V) provides additional performance margin
• Supply availability or cost considerations favor the MPR series

Both parts maintain identical electrical performance in DC link filtering and high-frequency switching applications. Both are RoHS3 compliant, MSL 1 rated, and REACH unaffected. Lead spacing (27.50mm) is identical, ensuring PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can 225MPR250K be used as a direct replacement for DPM2W2P2K-F in all applications?

A: Yes, for electrical circuit function. The 225MPR250K is electrically equivalent with identical capacitance (2.2 µF), voltage rating (250V DC), tolerance (±10%), dielectric material (polypropylene metallized), and operating temperature range (-55°C ~ 105°C). Physical dimensions differ: the substitute is lower profile (0.827" H vs. 1.063" H) and slightly shorter (1.220" L vs. 1.260" L). Verify PCB mechanical clearance before substitution.

Q: Are the lead spacings identical between these parts?

A: Yes. Both DPM2W2P2K-F and 225MPR250K have identical lead spacing of 1.083" (27.50mm). PCB footprints designed for either part are interchangeable in this dimension.

Q: What is the significance of the different AC voltage ratings (160V vs. 200V)?

A: The DPM2W2P2K-F is rated 160V AC, while the 225MPR250K is rated 200V AC. Both are rated 250V DC. In DC-only applications (DC link filtering, DC filtering), the AC rating is not a limiting factor. The substitute's higher AC rating provides additional performance margin if AC voltage stress is present in the circuit.

Q: Do both parts have the same compliance certifications?

A: Yes. Both DPM2W2P2K-F and 225MPR250K are RoHS3 compliant, MSL 1 rated (unlimited moisture sensitivity), and REACH unaffected. Regulatory compliance is identical.

Q: Which part should be selected for new designs?

A: For new designs, either part is acceptable based on electrical requirements. The 225MPR250K offers a lower profile form factor (0.827" H), which may provide PCB layout advantages. The DPM2W2P2K-F maintains the original specification envelope. Both are active products with stable supply status.

Q: Are there any performance differences in ESR or ESL characteristics?

A: The DPM2W2P2K-F is specified with low ESR and low ESL features. The 225MPR250K is specified with low ESR. Both parts use identical polypropylene metallized dielectric construction, which inherently provides low ESL performance. Detailed ESR/ESL curves should be obtained from manufacturer datasheets for specific circuit analysis.

Q: What is the inventory status for these parts?

A: DPM2W2P2K-F: 801 pcs new original in stock. 225MPR250K: 1723 pcs new original in stock. The substitute part has higher current inventory availability.
