Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MMP2W1P5K-F are determined by strict equivalency in the following critical electrical and mechanical parameters:

• Capacitance Value: 1.5 µF (exact match required)
• Tolerance: ±10% (matching tolerance specification)
• Voltage Rating - DC: 250V (minimum DC rating requirement)
• Voltage Rating - AC: 160V (minimum AC rating requirement)
• Dielectric Type: Polyester, Metallized (specific dielectric composition)
• Package Type: Axial (through-hole mounting configuration)
• Termination: PC Pins (pin configuration for circuit board assembly)
• Compliance: ROHS3 and REACH compliance maintained

The 155MWR250K is classified as a direct equivalent based on matching all required electrical parameters and maintaining identical package type and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both MMP2W1P5K-F and 155MWR250K are active-status products maintaining ROHS3 and REACH compliance. The selection between these equivalent parts is determined by application-specific requirements:

MMP2W1P5K-F Selection Criteria: Applications requiring extended operating temperature range from -55°C to 125°C and established design history with MMP series components.

155MWR250K Selection Criteria: Applications operating within -40°C to 105°C temperature range where sourcing availability or inventory levels favor MWR series components. This substitute maintains identical electrical specifications and compliance certifications.

Both parts are functionally interchangeable for general-purpose applications within their respective temperature operating windows, as electrical characteristics, voltage ratings, capacitance values, tolerances, and dielectric composition are identical.

Frequently Asked Questions (FAQ)

Q: Can the 155MWR250K replace the MMP2W1P5K-F in all applications? A: Yes, for applications operating within the 155MWR250K temperature range of -40°C to 105°C. Both parts match in capacitance, tolerance, voltage rating, dielectric material, package type, and compliance status.

Q: What are the physical dimension differences between these parts? A: The MMP2W1P5K-F measures 0.591" W × 0.335" T × 1.260" L (15.00mm × 8.50mm × 32.00mm). The 155MWR250K measures 0.472" Dia × 1.142" L (12.00mm × 29.00mm). Physical differences require verification for fit within circuit board layouts and enclosure constraints.

Q: Are there electrical performance differences between these substitutes? A: Both parts share identical electrical specifications for capacitance, tolerance, and voltage rating. The 155MWR250K specifies ESR (Equivalent Series Resistance) at 1.179 Ohms. ESR specifications are critical for high-frequency or noise-sensitive applications.

Q: Do both parts meet compliance requirements? A: Yes. Both MMP2W1P5K-F and 155MWR250K are ROHS3 Compliant and REACH Unaffected with Moisture Sensitivity Level 1 (Unlimited).

Q: Which part should be selected for thermal stress environments? A: Applications requiring operation at temperatures below -40°C or above 105°C must use the MMP2W1P5K-F, which maintains specifications to -55°C and 125°C. The 155MWR250K is restricted to -40°C ~ 105°C operation.
