MMP6W2P2K-F Equivalent & Substitute Parts

Part Overview

The MMP6W2P2K-F is a 2.2 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) rated for 630V DC operation. This axial-mounted through-hole component utilizes polyester metallized dielectric technology and is classified as Active product status. The part is designed for general-purpose applications requiring long-life performance across industrial temperature ranges.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits selection from qualified alternative manufacturers. The QAK2J225KTP from Nichicon represents an equivalent option meeting the core electrical specifications, though with notable differences in operating temperature range and product status classification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMP6W2P2K-F is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance value: 2.2 µF
• Tolerance: ±10%
• Voltage Rating - DC: 630V
• Dielectric Material: Polyester, Metallized
• Mounting Type: Through Hole
• Package / Case: Axial
• Termination: PC Pins

The QAK2J225KTP satisfies all critical matching parameters. Both components feature identical capacitance, tolerance, DC voltage rating, dielectric composition, mounting configuration, and termination type. Physical dimensions vary slightly within acceptable tolerances for axial-mounted through-hole applications. Both parts maintain ROHS3 compliance and REACH Unaffected status.

Differences in operating temperature range (-55°C ~ 125°C for MMP6W2P2K-F versus -40°C ~ 85°C for QAK2J225KTP) and product status (Active versus Obsolete) require evaluation within specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

MMP6W2P2K-F Selection Criteria: The MMP6W2P2K-F maintains Active product status with established long-term availability. This component is suitable for applications requiring extended operating temperature performance (-55°C ~ 125°C) and specified AC voltage rating of 250V. ROHS3 compliance and REACH Unaffected status satisfy regulatory requirements for industrial and commercial deployments.

QAK2J225KTP Selection Criteria: The QAK2J225KTP is classified as Obsolete, indicating discontinued manufacturing and limited inventory availability. This substitute is electrically equivalent for DC voltage applications at 630V with matching capacitance and tolerance specifications. The narrower operating temperature range (-40°C ~ 85°C) restricts deployment to applications within these thermal boundaries. Selection of this substitute requires confirmation that application temperature requirements do not exceed the specified limits.

Both components maintain identical RoHS3 and REACH compliance status, supporting equivalent regulatory positioning for end-use applications.

Frequently Asked Questions (FAQ)

Q: Can QAK2J225KTP directly replace MMP6W2P2K-F in all applications?

A: Direct replacement is possible when application operating temperature remains within -40°C ~ 85°C. Applications requiring operation below -40°C or above 85°C require the MMP6W2P2K-F due to its extended temperature range of -55°C ~ 125°C.

Q: Are the physical dimensions compatible for PCB mounting?

A: Both components are axial through-hole mounted with PC pin termination. Dimensional differences (MMP6W2P2K-F: 28.00mm W x 49.00mm L; QAK2J225KTP: 27.50mm W x 50.00mm L) are within acceptable tolerances for standard through-hole PCB layouts. Lead spacing and hole positioning remain compatible.

Q: What is the significance of the Obsolete product status for QAK2J225KTP?

A: Obsolete status indicates the QAK2J225KTP is no longer manufactured by Nichicon. Current inventory availability is limited to existing stock. Long-term supply chain planning should prioritize the Active MMP6W2P2K-F for new designs or production commitments.

Q: Do both parts meet the same regulatory compliance standards?

A: Both components are ROHS3 Compliant and REACH Unaffected, satisfying equivalent regulatory requirements for industrial and commercial applications.

Q: Is AC voltage rating a critical parameter for substitution?

A: The MMP6W2P2K-F specifies 250V AC rating while QAK2J225KTP does not provide AC voltage specification. Applications requiring AC voltage operation should confirm QAK2J225KTP suitability through detailed application analysis, as AC rating data is not provided in component documentation.

Q: What is the inventory status for each part?

A: MMP6W2P2K-F: 1147 pieces in stock. QAK2J225KTP: 896 pieces in stock. Both represent current available inventory from original manufacturers.
