Substitute Part Grouping Explanation

Substitution of the MMP2W2P2K is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 2.2 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 250V (minimum requirement; higher ratings acceptable)
• Voltage Rating - AC: 160V (minimum requirement; higher ratings acceptable)
• Dielectric Type: Polyester, Metallized (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Configuration: Through Hole, Axial (exact match required)
• Physical Dimensions: 18.00mm × 10.00mm × 35.00mm (exact match required for PCB compatibility)
• Termination Style: PC Pins (exact match required)

The MMP2W2P2K-F qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Engineering Selection Recommendations

The MMP2W2P2K-F is the direct equivalent substitute for the obsolete MMP2W2P2K. Selection is based on the following engineering factors:

Product Status: The MMP2W2P2K-F maintains active product status with Cornell Dubilier Electronics, ensuring continued availability and supply chain reliability. The original MMP2W2P2K is obsolete and subject to inventory depletion.

Electrical Equivalence: All electrical parameters are identical, including capacitance, tolerance, voltage ratings, and dielectric composition. The substitute operates within the same temperature range and maintains equivalent performance characteristics for general-purpose applications.

Mechanical Compatibility: Physical dimensions and mounting configuration are identical. The axial through-hole design with PC pin termination ensures direct PCB compatibility without layout modifications.

Regulatory Compliance: The MMP2W2P2K-F achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts maintain REACH Unaffected status. For applications subject to RoHS requirements, the substitute provides enhanced regulatory alignment.

Packaging: The MMP2W2P2K-F is supplied in bulk packaging, offering procurement flexibility compared to the original part's standard packaging designation.
