Key Parameters

Substitute Part Grouping Explanation

The 225MWR050K qualifies as a substitute based on the following critical electrical and mechanical parameters:

Matching Parameters:

• Voltage Rating (DC): 50V
• Tolerance: ±10%
• Dielectric Material: Polyester
• Mounting Type: Through Hole
• Package / Case: Axial
• Termination: PC Pins
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parameter Variation:

• Capacitance: 2.2 µF (compared to 2 µF in the primary part)
• Operating Temperature: -40°C ~ 105°C (compared to -55°C ~ 125°C)
• Physical Dimensions: Smaller footprint (9.00mm x 14.50mm vs 16.80mm x 41.30mm)

The 225MWR050K operates within the same voltage and tolerance specifications, maintaining polyester film dielectric properties and axial package configuration. The capacitance variance of 0.2 µF falls within the ±10% tolerance band, permitting direct substitution in general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Both the WMF05W2K-F and 225MWR050K maintain active product status with full ROHS3 compliance and REACH unaffected classification. Selection between these components depends on specific application constraints. The WMF05W2K-F provides a broader operating temperature range (-55°C ~ 125°C), suitable for extended environmental conditions. The 225MWR050K offers a more compact footprint and metallized polyester construction with lower ESR characteristics, applicable where space constraints or electrical performance requirements necessitate selection. Both components meet the same voltage rating, tolerance, and moisture sensitivity specifications required for general-purpose film capacitor applications.

Frequently Asked Questions (FAQ)

Q: Can the 225MWR050K directly replace the WMF05W2K-F?

A: The 225MWR050K functions as a substitute in applications where the capacitance variance of 0.2 µF and the reduced operating temperature range (-40°C ~ 105°C) accommodate circuit design specifications. Both components maintain equivalent voltage ratings, tolerance bands, and compliance certifications.

Q: What is the capacitance difference between these parts?

A: The WMF05W2K-F is rated at 2 µF while the 225MWR050K is rated at 2.2 µF. This 0.2 µF difference falls within the ±10% tolerance specification of both components, permitting functional equivalence in general-purpose applications.

Q: Are there physical space considerations?

A: The 225MWR050K has a significantly smaller axial package (9.00mm x 14.50mm) compared to the WMF05W2K-F (16.80mm x 41.30mm). Space-constrained PCB layouts may favor the 225MWR050K, while board designs accommodating larger components remain compatible with the WMF05W2K-F.

Q: Do both components meet the same compliance standards?

A: Both the WMF05W2K-F and 225MWR050K are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for industrial and commercial applications.

Q: What is the operating temperature difference?

A: The WMF05W2K-F operates across -55°C ~ 125°C while the 225MWR050K operates across -40°C ~ 105°C. Applications requiring operation at extreme low temperatures below -40°C or extreme high temperatures above 105°C require the WMF05W2K-F.
