MMP2P33K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The MMP2P33K-F is a 0.33 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), designed for general-purpose applications requiring stable capacitance and reliable performance across industrial temperature ranges. This axial-mounted through-hole component operates at 250V DC with ±10% tolerance and polyester metallized dielectric construction. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct circuit board replacement without performance degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MMP2P33K-F are identified based on strict electrical and mechanical parameter matching. The primary substitution criterion is capacitance value at 0.33 µF, which must remain constant. Voltage ratings (250V DC / 160V AC) establish the minimum performance envelope and cannot be reduced. The dielectric material (polyester, metallized) and operating temperature range (-55°C to 125°C) must remain consistent to preserve circuit behavior and reliability.

Mechanical compatibility requires matching mounting type (through hole), package form (axial), and termination style (PC pins). Physical dimensions may vary within acceptable tolerances provided the component fits the PCB layout and does not create assembly conflicts.

Tolerance specifications determine acceptable capacitance variation. A substitute with tighter tolerance (±5%) is electrically compatible with applications designed for ±10% tolerance, as it falls within the original specification envelope. Regulatory compliance (RoHS3, REACH Unaffected) must be maintained.

The substitute part 150334J250FC meets all these criteria with identical capacitance, voltage ratings, dielectric material, temperature range, mounting type, and termination. The primary difference is improved tolerance specification (±5% versus ±10%) and slightly different physical dimensions, both of which are acceptable substitution parameters.

Parameter Comparison

Engineering Selection Recommendations

The 150334J250FC serves as a direct electrical substitute for the MMP2P33K-F in applications where the 0.33 µF capacitance, 250V DC / 160V AC voltage ratings, and polyester metallized dielectric are specified. Both components are manufactured by Cornell Dubilier Electronics and maintain identical regulatory compliance (RoHS3 Compliant, REACH Unaffected, EAR99 ECCN classification).

The substitute part offers improved tolerance specification (±5% versus ±10%), which provides tighter capacitance control and may enhance circuit performance in applications sensitive to capacitance variation. This tighter tolerance is a technical advantage and does not create compatibility issues.

Physical dimensions differ between the two parts. The substitute (8.50mm x 20.50mm) is smaller than the main part (10.50mm x 23.00mm). PCB layout verification is required to confirm the substitute component fits within the allocated space and does not create assembly conflicts with adjacent components or board features.

Both parts maintain Active product status with established supply chains. Selection between these parts should be based on PCB layout constraints and tolerance requirements specific to the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the 150334J250FC replace the MMP2P33K-F in any application?

A: Electrical replacement is valid for all applications designed for 0.33 µF at 250V DC / 160V AC with polyester metallized dielectric. Physical fit must be confirmed due to dimensional differences. The substitute's smaller size (8.50mm x 20.50mm versus 10.50mm x 23.00mm) requires PCB layout verification.

Q: What is the significance of the tolerance difference (±5% versus ±10%)?

A: The substitute part's ±5% tolerance is tighter than the main part's ±10% tolerance. This means the substitute maintains capacitance closer to the nominal 0.33 µF value. Tighter tolerance is compatible with applications designed for ±10% tolerance and may provide improved circuit performance in sensitive applications.

Q: Are both parts manufactured by the same company?

A: Yes, both the MMP2P33K-F and 150334J250FC are manufactured by Cornell Dubilier Electronics (CDE), ensuring consistent quality standards and manufacturing processes.

Q: Do both parts meet the same regulatory requirements?

A: Yes, both parts are RoHS3 Compliant, REACH Unaffected, and classified as EAR99 under ECCN. Regulatory compliance is identical between the two components.

Q: What is the primary consideration when selecting between these parts?

A: The primary consideration is PCB layout compatibility. The substitute part is physically smaller and must fit within the allocated board space. If space constraints are not an issue, the substitute's improved tolerance specification may be advantageous.

Q: Are there any performance differences between these capacitors?

A: Both capacitors use identical polyester metallized dielectric construction and operate across the same temperature range (-55°C to 125°C). Electrical performance is equivalent. The substitute offers tighter tolerance control, which may reduce capacitance variation in the circuit.

Q: Can I use the MMP2P33K-F as a substitute for the 150334J250FC?

A: Yes, the MMP2P33K-F is electrically compatible with applications designed for the 150334J250FC. However, the main part is physically larger (10.50mm x 23.00mm versus 8.50mm x 20.50mm), so PCB layout must accommodate the larger dimensions.
