Murata Power Solutions 50105AC Common Mode Choke - Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 50105AC is a surface mount common mode choke (CMC) designed for signal line filtering applications. This 2-line toroidal inductor delivers 1 mH inductance at 100 kHz with a maximum current rating of 700 mA and 360 mOhm DC resistance. The component is actively manufactured, RoHS3 compliant, and suitable for electromagnetic interference (EMI) suppression in communication and data line circuits. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required for design flexibility or supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the 50105AC are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameter is inductance value, which directly determines filtering performance in signal line applications. The 50474AC is classified as a parametric equivalent because it maintains the following critical matching parameters:

• Number of Lines: 2 (identical)
• Current Rating (Max): 700 mA (identical)
• DC Resistance (Max): 360 mOhm (identical)
• Mounting Type: Surface Mount (identical)
• Package / Case: Horizontal, 4 Gull Wing (identical)
• Physical Dimensions: 0.236" L x 0.280" W x 0.197" H (identical)
• Operating Temperature Range: -40°C to 125°C (identical)
• Series: 5000A (identical)
• RoHS Status: RoHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

The 50474AC differs in inductance value (470 µH @ 100 kHz versus 1 mH @ 100 kHz), making it suitable for applications requiring lower inductance filtering characteristics while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 50105AC and 50474AC are active products from Murata Power Solutions Inc. within the 5000A series. Both components are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and commercial applications. Selection between these parts depends on the specific inductance requirement of the application circuit. The 50105AC provides 1 mH filtering performance, while the 50474AC provides 470 µH filtering performance. Both maintain identical current handling capacity (700 mA), DC resistance (360 mOhm), thermal operating range (-40°C to 125°C), and physical form factor (Horizontal, 4 Gull Wing surface mount package). Component selection should be based on the required inductance value for the target signal line filtering application.

Frequently Asked Questions (FAQ)

Q: Can the 50474AC be used as a direct replacement for the 50105AC?

A: The 50474AC is mechanically and electrically compatible in terms of mounting, current rating, DC resistance, and thermal performance. However, the inductance value differs (470 µH versus 1 mH). Substitution is valid only if the application circuit design accommodates the lower inductance value of the 50474AC.

Q: What is the primary difference between these two parts?

A: The inductance value at 100 kHz is the primary difference. The 50105AC provides 1 mH inductance, while the 50474AC provides 470 µH inductance. All other electrical and mechanical parameters are identical.
