DPM2S22K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPM2S22K-F is a 0.022 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPM series. This radial polypropylene metallized film capacitor is rated for 250V DC operation with ±10% tolerance and is designed for DC link, DC filtering, and high-frequency switching applications. The part is currently active in production with 1036 pieces in stock. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when design requirements permit alternative configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPM2S22K-F are identified based on strict electrical and mechanical parameter matching. The substitution logic requires:

Electrical Parameters (Non-negotiable):

• Capacitance value: 0.022 µF (exact match)
• DC voltage rating: 250V minimum
• AC voltage rating: 160V minimum
• Tolerance: ±10% or tighter
• Dielectric: Polypropylene (PP), Metallized
• Temperature range: -55°C to 105°C minimum

Mechanical Parameters (Non-negotiable):

• Mounting type: Through Hole, Radial
• Lead spacing: 0.394" (10.00mm)
• Termination: PC Pins

Regulatory Parameters (Non-negotiable):

• RoHS3 Compliance
• REACH Unaffected status

The substitute part 223MPR250K from Cornell Dubilier / Illinois Capacitor meets all critical electrical and mechanical parameters. Physical dimensions may vary within acceptable limits for through-hole radial mounting, provided lead spacing and termination type remain constant.

Parameter Comparison

Engineering Selection Recommendations

The 223MPR250K is a direct electrical and functional equivalent to the DPM2S22K-F. Both parts are manufactured by Cornell Dubilier and maintain identical electrical specifications, voltage ratings, tolerance, dielectric material, and operating temperature range. Both parts are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for current production and procurement.

The primary difference between the two parts is physical packaging. The 223MPR250K features a more compact radial design with reduced height (9.00mm vs. 14.00mm) and narrower width (5.00mm vs. 7.00mm), while maintaining the same 10.00mm lead spacing required for PCB compatibility. This dimensional difference is acceptable for substitution provided the PCB layout accommodates the smaller footprint. The substitute part's lower profile may offer advantages in space-constrained applications.

Both parts are active in production with adequate inventory availability (1036 pieces for DPM2S22K-F; 1729 pieces for 223MPR250K). Selection between the two should be based on PCB layout requirements and available board space.

Frequently Asked Questions (FAQ)

Q: Can the 223MPR250K replace the DPM2S22K-F in all applications?

A: Yes, from an electrical standpoint. The 223MPR250K meets all critical electrical parameters: 0.022 µF capacitance, 250V DC rating, 160V AC rating, ±10% tolerance, polypropylene metallized dielectric, and -55°C to 105°C operating range. Both parts have identical lead spacing (10.00mm) for PCB compatibility. Physical dimensions differ, so verify that the smaller footprint (13.00mm x 5.00mm x 9.00mm height) fits your PCB layout.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: (1) Capacitance value (0.022 µF exact match), (2) DC voltage rating (250V minimum), (3) AC voltage rating (160V minimum), (4) Tolerance (±10% or tighter), (5) Dielectric type (polypropylene metallized), (6) Operating temperature range (-55°C to 105°C), (7) Mounting type (through-hole radial), (8) Lead spacing (10.00mm), and (9) Regulatory compliance (ROHS3, REACH unaffected).

Q: Are there any performance differences between these parts?

A: Both parts are specified for DC link, DC filtering, and high-frequency switching applications with low ESR and low ESL characteristics. The 223MPR250K provides an ESR specification of 8.038 Ohms. The DPM2S22K-F does not specify ESR in the provided data. Both parts meet the same application requirements.

Q: What is the impact of the different physical dimensions?

A: The 223MPR250K is more compact (9.00mm height vs. 14.00mm, 5.00mm width vs. 7.00mm). This is advantageous for space-constrained designs. The critical dimension for PCB compatibility is lead spacing, which is identical at 10.00mm for both parts. Verify that your PCB layout can accommodate the smaller footprint before substitution.

Q: Are both parts currently available?

A: Yes. The DPM2S22K-F has 1036 pieces in stock. The 223MPR250K has 1729 pieces in stock. Both are active production parts from Cornell Dubilier.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the DPM2S22K-F and 223MPR250K are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component procurement and production.
