MMP6P15K-F Equivalent and Substitute Parts

Part Overview

The MMP6P15K-F is a 0.15 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 630V DC voltage rating, designed for general-purpose applications requiring high voltage performance. This axial-mounted polyester metallized capacitor is currently in active production status with 929 units in stock. Substitutes become necessary when specific voltage, temperature, or packaging requirements of an application differ from the primary part's specifications, or when inventory constraints require alternative qualified equivalents.

Key Parameters

Substitute Part Grouping Explanation

The MMP6P15K-F can be substituted with the 154MWR400K based on the following critical electrical parameters:

Matching Parameters:

• Capacitance: 0.15 µF (identical)
• Tolerance: ±10% (identical)
• Dielectric Material: Polyester, Metallized (identical)
• Mounting Type: Through Hole (identical)
• Package Type: Axial (identical)
• RoHS Compliance: ROHS3 Compliant (identical)

Differentiating Parameters:

• Voltage Rating - DC: MMP6P15K-F rated 630V; 154MWR400K rated 400V
• Voltage Rating - AC: MMP6P15K-F rated 250V; 154MWR400K rated 200V
• Operating Temperature: MMP6P15K-F: -55°C ~ 125°C; 154MWR400K: -40°C ~ 105°C

The 154MWR400K is a lower-voltage alternative suitable for applications requiring 400V DC or less. Substitution is valid only when the application's voltage requirements do not exceed 400V DC and 200V AC.

Parameter Comparison

Engineering Selection Recommendations

Both the MMP6P15K-F and 154MWR400K maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronics manufacturing. The MMP6P15K-F is the primary selection for applications requiring maximum voltage rating of 630V DC or extended temperature performance down to -55°C. The 154MWR400K is suitable for lower-voltage applications (400V DC maximum) within the narrower operating temperature range of -40°C to 105°C. Inventory availability should be assessed based on application schedules, as the MMP6P15K-F currently shows 929 units in stock while the 154MWR400K shows 4259 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the 154MWR400K replace the MMP6P15K-F in a 600V DC circuit? A: No. The 154MWR400K has a maximum DC voltage rating of 400V. Circuits requiring 600V DC operation must use the MMP6P15K-F or equivalent 630V-rated capacitor.

Q: Are the physical dimensions compatible between these parts? A: Both parts feature axial mounting through-hole packages, but with different physical dimensions. The MMP6P15K-F measures 23.00mm length, while the 154MWR400K measures 19.00mm length. Verify board layout and footprint compatibility before substitution.

Q: What is the temperature rating difference, and does it matter? A: The MMP6P15K-F operates from -55°C to 125°C, while the 154MWR400K operates from -40°C to 105°C. If your application requires operation below -40°C or above 105°C, the MMP6P15K-F is required.

Q: Are both parts ROHS compliant? A: Yes. Both the MMP6P15K-F and 154MWR400K are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory standards for component selection.

Q: What does the identical ±10% tolerance mean for substitution? A: Both capacitors have identical tolerance specifications, meaning they provide equivalent capacitance accuracy for the 0.15 µF value within ±10% of the nominal specification.
