DMM2P47K-F Equivalent & Substitute Parts

Part Overview

The DMM2P47K-F is a 0.47 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) rated for 250V DC operation with ±10% tolerance. This radial through-hole component utilizes polyester metallized dielectric technology and operates across the temperature range of -55°C to 125°C. The part maintains Active product status with full RoHS3 compliance and REACH unaffected classification. Equivalent and substitute parts are identified for applications requiring identical electrical performance or where alternative packaging, lead spacing, or physical dimensions accommodate design constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DMM2P47K-F is determined by strict equivalence across the following electrical parameters: capacitance value (0.47 µF), tolerance (±10%), DC voltage rating (250V), AC voltage rating (160V), dielectric material composition (polyester metallized), operating temperature range (-55°C to 125°C), and termination type (PC pins). All identified substitute parts maintain identical electrical specifications and compliance certifications. Physical dimensions, lead spacing, and packaging format may vary between the main part and substitutes, requiring verification against specific printed circuit board layout constraints. Mechanical compatibility must be confirmed prior to implementation.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical equivalence to the DMM2P47K-F across capacitance, voltage rating, tolerance, temperature range, and compliance certifications. Selection between the main part and substitutes is determined by physical space constraints and lead spacing requirements on the target printed circuit board.

The DME2P47K-F (CDE) provides a direct series alternative with reduced physical dimensions (18.50mm length, 15.00mm lead spacing) while maintaining identical electrical specifications and CDE manufacturing origin.

The EPCOS B3252* series parts (B32521C3474K000, B32521C3474K189, B32522C3474K000) offer the most compact form factors with lead spacing ranging from 10.00mm to 15.00mm and seated heights between 11.00mm and 12.00mm. These parts incorporate stacked metallized polyethylene terephthalate (PET) dielectric construction and carry AEC-Q200 automotive qualification ratings. All EPCOS variants maintain Active product status with full RoHS3 and REACH compliance.

The B32521C3474K189 is supplied in Cut Tape (CT) packaging, while B32521C3474K000 and B32522C3474K000 are supplied in Bulk packaging. Packaging selection depends on assembly process requirements and inventory management protocols.

Frequently Asked Questions (FAQ)

Q: Can the DME2P47K-F replace the DMM2P47K-F in all applications?

A: The DME2P47K-F is electrically equivalent to the DMM2P47K-F across all specified parameters. Physical dimensions differ: the DME2P47K-F measures 18.50mm length with 15.00mm lead spacing compared to the DMM2P47K-F at 26.00mm length with 22.50mm lead spacing. Substitution requires confirmation that the printed circuit board layout accommodates the reduced lead spacing and physical envelope.

Q: What is the primary difference between CDE and EPCOS substitute parts?

A: Both manufacturers provide electrically equivalent 0.47 µF 250V DC film capacitors with identical tolerance, voltage rating, and operating temperature specifications. EPCOS parts utilize stacked metallized PET dielectric construction and carry AEC-Q200 automotive qualification. CDE parts use standard polyester metallized construction. Physical dimensions vary across all options, requiring board layout verification.

Q: Are the EPCOS B32521C3474K000 and B32521C3474K189 interchangeable?

A: These parts are electrically and mechanically identical. The primary difference is packaging format: B32521C3474K000 is supplied in Bulk packaging while B32521C3474K189 is supplied in Cut Tape (CT) packaging. Selection depends on assembly process requirements and component handling protocols.

Q: Which substitute part offers the smallest physical footprint?

A: The EPCOS B32521C3474K000 and B32521C3474K189 provide the most compact form factor at 13.00mm length, 6.00mm width, and 12.00mm seated height with 10.00mm lead spacing. These dimensions represent the smallest envelope among all listed equivalents.

Q: Do all substitute parts maintain the same compliance certifications as the DMM2P47K-F?

A: All substitute parts maintain RoHS3 compliance and REACH unaffected status. The EPCOS B3252* series additionally carries AEC-Q200 automotive qualification ratings. All parts are Active product status with unlimited shelf life (MSL 1 or Not Applicable).

Q: What lead spacing options are available across all substitute parts?

A: Lead spacing options are 10.00mm (EPCOS B32521C3474K* series), 15.00mm (CDE DME2P47K-F and EPCOS B32522C3474K000), and 22.50mm (original DMM2P47K-F). Board layout must accommodate the selected lead spacing configuration.
