DPM2S1K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPM2S1K-F is a 10000 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 250V DC voltage rating. This radial polypropylene metallized capacitor is designed for DC link and DC filtering applications requiring low ESR and low ESL characteristics. The part is currently in active production status with 674 units in stock. Substitute parts are identified when equivalent electrical performance is required but the original part is unavailable, or when design specifications permit higher voltage ratings or alternative packaging configurations.

Substitute Part Grouping Explanation

Substitute parts for the DPM2S1K-F are identified based on the following substitution criteria:

Electrical Equivalence Requirements:

• Capacitance value must be 10000 pF (no tolerance variation permitted)
• Tolerance must be ±10% or tighter
• Voltage rating must be equal to or greater than 250V DC
• Dielectric material must be polypropylene (PP), metallized construction
• Operating temperature range must encompass -55°C to 105°C

Mechanical Compatibility Requirements:

• Mounting type must be through-hole radial configuration
• Lead spacing must be 0.394" (10.00mm) to ensure PCB hole pattern compatibility
• Package/case type must be radial

Compliance Requirements:

• RoHS3 compliance must be maintained
• REACH unaffected status must be preserved

The substitute part 103MPR400K meets all substitution criteria. It maintains identical capacitance, tolerance, temperature range, mounting type, and lead spacing while providing a higher voltage rating (400V DC versus 250V DC). This higher voltage rating provides additional design margin and is acceptable in applications where the original 250V specification is not a limiting constraint.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (DPM2S1K-F): Select the DPM2S1K-F when the original part number is available and design specifications require the exact 250V DC voltage rating. This part is in active production with adequate inventory (674 units in stock) and maintains full ROHS3 and REACH compliance.

Substitute Selection (103MPR400K): The 103MPR400K is a direct substitute when the DPM2S1K-F is unavailable. This part is suitable for applications where:

• The circuit design permits operation at 400V DC (higher than the original 250V specification)
• The more compact physical dimensions (9.00mm height versus 14.00mm) are compatible with PCB layout constraints
• Higher inventory availability is required (7142 units in stock versus 674 units)

Both parts maintain identical electrical performance for capacitance, tolerance, temperature range, and lead spacing. Both are manufactured within the Cornell Dubilier family and maintain equivalent compliance certifications. The substitute part's higher voltage rating and reduced physical footprint present no compatibility issues for direct substitution in applications where these characteristics are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 103MPR400K replace the DPM2S1K-F in all applications?

A: The 103MPR400K is electrically and mechanically compatible with the DPM2S1K-F for direct substitution. Both parts have identical capacitance (10000 pF), tolerance (±10%), operating temperature range (-55°C to 105°C), mounting type (through-hole radial), and lead spacing (10.00mm). The substitute part has a higher voltage rating (400V DC versus 250V DC) and more compact physical dimensions, which are acceptable in applications where these characteristics do not conflict with design requirements.

Q: What are the physical dimension differences between these parts?

A: The DPM2S1K-F measures 0.512" L x 0.276" W x 0.551" H (13.00mm x 7.00mm x 14.00mm). The 103MPR400K measures 0.512" L x 0.197" W x 0.354" H (13.00mm x 5.00mm x 9.00mm). The length is identical, but the substitute part is narrower and significantly shorter. Verify that the reduced height and width are compatible with your PCB layout and component placement constraints.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the DPM2S1K-F and 103MPR400K are ROHS3 compliant and REACH unaffected. Both parts maintain equivalent environmental and regulatory compliance status.

Q: What is the lead spacing for both parts?

A: Both parts have a lead spacing of 0.394" (10.00mm). This identical spacing ensures that both parts are compatible with the same PCB hole pattern and footprint.

Q: Why does the substitute part have a higher voltage rating?

A: The 103MPR400K is rated for 400V DC compared to the DPM2S1K-F's 250V DC rating. Higher voltage ratings in film capacitors typically result from design variations in the dielectric thickness and construction. This higher rating provides additional design margin and is acceptable for direct substitution in applications where the circuit voltage does not exceed the original 250V specification.

Q: Are there any ESR or performance differences?

A: The 103MPR400K specifies an ESR of 17.684 Ohms. The DPM2S1K-F does not provide an ESR specification in the available data. Both parts are specified with low ESR and low ESL characteristics suitable for DC link and DC filtering applications. Verify ESR specifications against your application requirements if this parameter is critical to circuit performance.

Q: What is the inventory status for each part?

A: The DPM2S1K-F has 674 units in stock. The 103MPR400K has 7142 units in stock. The substitute part offers significantly higher availability if supply chain continuity is a consideration.
