MMP2P1K Film Capacitor Equivalent & Substitute Parts

Part Overview

The MMP2P1K is a 0.1 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 250V DC voltage rating and ±10% tolerance. This component is classified as obsolete, which necessitates identification of active equivalent parts for continued system support and procurement. The MMP2P1K features polyester metallized dielectric construction in an axial through-hole package, suitable for general-purpose applications requiring stable capacitance across extended temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMP2P1K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Non-negotiable):

• Capacitance value: 0.1 µF
• Tolerance: ±10%
• Voltage rating - DC: 250V minimum
• Voltage rating - AC: 160V minimum
• Dielectric material: Polyester, Metallized
• Operating temperature range: -55°C to 125°C minimum

Mechanical Parameters (Non-negotiable):

• Mounting type: Through Hole
• Package type: Axial
• Physical dimensions: 0.335" W × 0.217" T × 0.669" L
• Termination: PC Pins

The MMP2P1K-F satisfies all electrical and mechanical equivalence criteria and is classified as an active product, making it suitable for direct substitution in applications currently using the obsolete MMP2P1K.

Parameter Comparison

Engineering Selection Recommendations

The MMP2P1K-F is the direct equivalent substitute for the obsolete MMP2P1K. Both parts are manufactured by Cornell Dubilier Electronics within the MMP series and share identical electrical specifications and physical dimensions.

Primary Advantage: The MMP2P1K-F carries active product status, ensuring continued availability and supply chain reliability. Additionally, the MMP2P1K-F is ROHS3 compliant, whereas the original MMP2P1K is non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the MMP2P1K-F is the required selection.

Compliance Consideration: Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), indicating no change in regulatory export or hazardous substance status.

Packaging Difference: The MMP2P1K-F is supplied in bulk packaging, whereas the original MMP2P1K packaging specification is not detailed. This distinction affects procurement and inventory management but does not alter electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MMP2P1K-F be used as a direct replacement for the MMP2P1K in existing circuit designs?

A: Yes. The MMP2P1K-F is electrically and mechanically equivalent to the MMP2P1K. All critical parameters—capacitance, voltage rating, tolerance, dielectric material, operating temperature range, and physical dimensions—are identical. The component can be substituted without circuit redesign or board layout modification.

Q: What is the primary reason for substituting the MMP2P1K?

A: The MMP2P1K is classified as obsolete. The MMP2P1K-F is the active equivalent, ensuring continued procurement availability and supply chain support.

Q: Are there any compliance differences between the MMP2P1K and MMP2P1K-F?

A: Yes. The MMP2P1K-F is ROHS3 compliant, while the MMP2P1K is RoHS non-compliant. For applications requiring RoHS compliance, the MMP2P1K-F is the appropriate selection. Both parts maintain identical REACH and ECCN status.

Q: Do the physical dimensions of the MMP2P1K-F match the MMP2P1K?

A: Yes. Both parts have identical axial package dimensions of 0.335" W × 0.217" T × 0.669" L (8.50mm × 5.50mm × 17.00mm). Board layout and mechanical fit are unchanged.

Q: What is the difference in packaging between these parts?

A: The MMP2P1K-F is supplied in bulk packaging. The original MMP2P1K packaging type is not specified in the technical data. This affects procurement quantity and handling but does not impact electrical or mechanical performance.

Q: Are the voltage ratings identical between the two parts?

A: Yes. Both the MMP2P1K and MMP2P1K-F have identical voltage ratings of 250V DC and 160V AC, with ±10% capacitance tolerance and -55°C to 125°C operating temperature range.
