MMWA2P47K-F

Part Overview

The MMWA2P47K-F is a 0.47 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 250V DC operation with polyester metallized dielectric construction. This through-hole axial component is rated Active and maintains operational capability across a temperature range of -55°C to 125°C. Equivalent and substitute parts become necessary when the primary component experiences supply constraints, long lead times, or when design specifications permit alternative packaging configurations while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMWA2P47K-F is determined by strict equivalence in the following critical parameters: capacitance value (0.47 µF), tolerance (±10%), DC voltage rating (250V minimum), dielectric material (polyester metallized), operating temperature range (-55°C ~ 125°C), mounting type (through hole), and package configuration (axial). The AC voltage rating may vary within acceptable operational bounds, and physical dimensions may differ provided the component fits circuit board constraints. The identified substitute, 150474K250HC, meets all mandatory electrical parameters and operates within the specified thermal envelope. Packaging format differences (bulk versus standard) do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the MMWA2P47K-F and 150474K250HC are Active status components manufactured by Cornell Dubilier Electronics, ensuring continued supply and technical support. Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and commercial applications. The 150474K250HC exhibits a higher AC voltage rating (160V versus 125V), providing enhanced margin in AC applications. Physical dimension differences (length reduction of 4.90mm on the 150474K250HC) require verification against circuit board layout constraints prior to substitution. Component selection should be based on available inventory levels, lead time requirements, and board space availability.

Frequently Asked Questions (FAQ)

Q: Can the 150474K250HC directly replace the MMWA2P47K-F in all applications? A: Electrical compatibility is confirmed. The DC and capacitance ratings are identical. Physical dimension differences must be validated against PCB layout constraints; the 150474K250HC is 4.90mm shorter in length.

Q: What are the critical parameters for substitution compatibility? A: Capacitance (0.47 µF), tolerance (±10%), DC voltage rating (250V), dielectric material (polyester metallized), operating temperature range (-55°C ~ 125°C), mounting type (through hole), and axial package configuration must remain constant.

Q: Are there regulatory or compliance concerns with using the substitute part? A: No. Both components maintain ROHS3 compliance and REACH Unaffected status, satisfying equivalent regulatory requirements.

Q: How does the AC voltage rating difference affect substitution? A: The 150474K250HC operates at 160V AC compared to the MMWA2P47K-F at 125V AC. This represents a higher rating on the substitute, providing additional margin in AC applications without creating incompatibility.

Q: What factors should determine final selection between these parts? A: Component availability, inventory levels, lead time, PCB layout space tolerance for the 4.90mm length difference, and packaging format requirements (bulk versus standard) should guide the selection decision.
