Equivalent & Substitute Parts for Murata Power Solutions 23S2R2C

Part Overview

The Murata Power Solutions 23S2R2C is a 2.2 µH shielded wirewound inductor rated for 2.1 A continuous current with a maximum DC resistance of 25mOhm. This component is designed for surface mount applications in the nonstandard package format and operates across the industrial temperature range of -40°C to 85°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent inductance values, current ratings, and shielding characteristics align within acceptable engineering tolerances for the application, while accounting for variations in core material, saturation current, and thermal operating ranges.

Key Parameters

Substitute Part Grouping Explanation

The Bourns Inc. SRR6603-2R2ML qualifies as a substitute based on the following alignment of critical parameters:

Matching Parameters:

• Inductance: 2.2 µH (identical)
• Shielding: Shielded (identical)
• Mounting Type: Surface Mount (identical)
• Package / Case: Nonstandard (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: MSL 1 (identical)

Acceptable Variations:

• Current Rating: 1.8 A (substitute) vs. 2.1 A (main part) — substitute rated lower but suitable for applications not requiring full 2.1 A capacity
• DC Resistance: 50mOhm Max (substitute) vs. 25mOhm Max (main part) — substitute exhibits higher resistance within acceptable engineering tolerance for equivalent inductance class
• Core Material: Ferrite drum core (substitute) vs. unspecified (main part) — both configurations deliver shielded wirewound performance
• Operating Temperature: -55°C ~ 125°C (substitute) vs. -40°C ~ 85°C (main part) — substitute provides extended thermal range

Parameter Comparison

Engineering Selection Recommendations

Both the Murata Power Solutions 23S2R2C and Bourns Inc. SRR6603-2R2ML maintain Active product status with full RoHS3 compliance and REACH unaffected designation. Selection between these parts depends on application-specific current requirements and thermal operating conditions.

The Murata 23S2R2C is the primary choice for applications requiring the full 2.1 A current rating and lower DC resistance of 25mOhm Max. The Bourns SRR6603-2R2ML serves as a substitute for designs operating within 1.8 A current limits and applications benefiting from the extended operating temperature range of -55°C to 125°C. The higher DC resistance of the Bourns part (50mOhm Max) must be evaluated against circuit power dissipation requirements.

Both parts are surface mount nonstandard package inductors with shielded wirewound construction, ensuring electromagnetic compatibility in equivalent application contexts.

Frequently Asked Questions (FAQ)

Q: Can the Bourns SRR6603-2R2ML directly replace the Murata 23S2R2C in all applications?

A: Substitution is valid only when the application current requirement does not exceed 1.8 A. The Bourns part's higher DC resistance (50mOhm vs. 25mOhm) increases power dissipation and must be evaluated against thermal design margins. Both parts deliver identical 2.2 µH inductance and shielded surface mount construction.

Q: What is the impact of the higher DC resistance in the Bourns substitute?

A: The Bourns SRR6603-2R2ML exhibits 50mOhm maximum DC resistance compared to 25mOhm in the Murata part. This doubles the resistive component and increases I²R losses proportionally. Circuit designs must account for this additional power dissipation when operating at rated current levels.

Q: Are the physical dimensions compatible between these parts?

A: Both parts use nonstandard package formats with different footprints. Murata 23S2R2C measures 0.244" L x 0.220" W x 0.126" H (6.20mm x 5.60mm x 3.20mm). Bourns SRR6603-2R2ML measures 0.260" L x 0.173" W x 0.118" H (6.60mm x 4.40mm x 3.00mm). PCB layout and mechanical clearance must be verified before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the Murata 23S2R2C and Bourns SRR6603-2R2ML are RoHS3 compliant, REACH unaffected, classified as EAR99, and carry HTSUS code 8504.50.4000. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the saturation current difference between these inductors?

A: The Bourns SRR6603-2R2ML specifies saturation current (Isat) of 920mA. The Murata 23S2R2C does not provide saturation current data in the available parameters. Applications requiring saturation current specifications must reference detailed datasheets or contact manufacturers directly.
