Murata Power Solutions 50474AC Common Mode Choke - Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 50474AC is a surface mount common mode choke (CMC) designed for signal line filtering applications. This 2-line toroidal inductor delivers 470 µH inductance at 100 kHz with a maximum current rating of 700mA and 360mOhm DC resistance. The component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative part selection becomes necessary when inventory constraints, application-specific inductance requirements, or supply chain considerations require substitution within the same mechanical and electrical envelope.

Substitute Part Grouping Explanation

Substitution eligibility for the 50474AC is determined by strict adherence to the following parameters:

Fixed Parameters (Non-Negotiable for Substitution):

• Manufacturer: Murata Power Solutions Inc.
• Series: 5000A
• Filter Type: Signal Line
• Number of Lines: 2
• Current Rating (Max): 700mA
• DC Resistance (Max): 360mOhm
• Mounting Type: Surface Mount
• Package / Case: Horizontal, 4 Gull Wing
• Physical Dimensions: 6.00mm L x 7.10mm W x 5.00mm H (Max)
• Operating Temperature Range: -40°C to 125°C

Variable Parameter (Allows Substitution):

• Inductance @ 100 kHz: 470 µH (primary specification; alternative inductance values within the same mechanical and electrical constraints qualify as substitutes)

The 50474AC has one identified parametric equivalent: Murata Power Solutions 50105AC. This substitute maintains all fixed parameters while offering a different inductance value (1 mH @ 100 kHz) within the same product series and mechanical footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the 50474AC and 50105AC maintain Active product status with full RoHS3 compliance and REACH unaffected designation. Selection between these parts is determined by circuit inductance requirements at 100 kHz operating frequency. The 50474AC provides 470 µH inductance, while the 50105AC provides 1 mH inductance. Both components share identical current handling capacity (700mA), DC resistance characteristics (360mOhm maximum), thermal operating range (-40°C to 125°C), and mechanical footprint specifications. Component selection should be based on the specific inductance value required by the application circuit design. Both parts are suitable for immediate deployment in production environments given their Active status and full compliance certifications.

Frequently Asked Questions (FAQ)

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

A: The 50105AC is mechanically and electrically compatible with the 50474AC in terms of mounting, current handling, DC resistance, and thermal performance. However, the inductance values differ (1 mH versus 470 µH at 100 kHz). Substitution is valid only if the application circuit design accommodates the higher inductance value of the 50105AC.

Q: Are there any package or footprint differences between these parts?

A: No. Both the 50474AC and 50105AC share identical mechanical specifications: 6.00mm length, 7.10mm width, 5.00mm maximum height, and Horizontal 4 Gull Wing package configuration. PCB layout and assembly processes remain unchanged between parts.

Q: What is the significance of the 360mOhm DC resistance specification?

A: The DC resistance (DCR) of 360mOhm maximum is a fixed parameter for both the 50474AC and 50105AC. This specification defines the resistive losses in the inductor windings and is critical for thermal management and power dissipation calculations in signal line filtering applications.

Q: Do both parts have the same current rating?

A: Yes. Both the 50474AC and 50105AC are rated for a maximum continuous current of 700mA. Current handling capacity is identical between the two parts.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical compliance status: RoHS3 compliant, REACH unaffected, MSL 1 (unlimited moisture sensitivity), and Active product status. No additional certifications or approvals are required when substituting between these parts.

Q: What determines whether I should select the 470 µH or 1 mH inductance value?

A: Inductance selection is determined by the signal line filtering requirements of your specific circuit application. The 470 µH value (50474AC) provides lower inductance filtering, while the 1 mH value (50105AC) provides higher inductance filtering. Circuit simulation or design specifications will indicate which inductance value is required.
