Murata 23S220C Equivalent & Substitute Parts

Part Overview

The Murata 23S220C is a 22 µH shielded wirewound inductor rated for 800 mA continuous current with a maximum DC resistance of 175 mOhm. Designed for surface mount applications in the 2300 series, this component operates across the industrial temperature range of -40°C to 85°C and maintains ROHS3 compliance. The part is currently active in production with substantial inventory availability. Substitute parts may be required due to supply constraints, design optimization needs, or specific application requirements that benefit from alternative core materials or performance characteristics.

Substitute Part Grouping Explanation

The Bourns SRR6603-220ML qualifies as a substitute for the Murata 23S220C based on the following critical parameters:

Matching Parameters:

• Inductance: Both parts are rated at 22 µH
• Shielding: Both are shielded designs
• Type: Both are wirewound inductors
• Mounting: Both are surface mount components
• Package: Both use nonstandard packaging with tape & reel delivery
• RoHS Compliance: Both meet ROHS3 requirements
• Inductance Test Frequency: Murata tested at 1 kHz; Bourns tested at 100 kHz

Allowable Variations:

• Current Rating: Bourns part rated at 700 mA versus Murata's 800 mA (acceptable for applications not requiring full 800 mA capacity)
• DC Resistance: Bourns 110 mOhm Max versus Murata's 175 mOhm Max (lower resistance is advantageous)
• Core Material: Murata uses unspecified core; Bourns uses ferrite core
• Operating Temperature: Bourns range -55°C ~ 125°C exceeds Murata's -40°C ~ 85°C
• Physical Dimensions: Minor variations in footprint (Murata 6.20mm x 5.60mm; Bourns 6.60mm x 4.40mm)

Parameter Comparison

Engineering Selection Recommendations

Both the Murata 23S220C and Bourns SRR6603-220ML maintain active product status with full regulatory compliance. Selection between these parts depends on application-specific current requirements and thermal operating conditions.

The Murata 23S220C is appropriate for applications requiring the full 800 mA current rating within the -40°C to 85°C temperature window.

The Bourns SRR6603-220ML is suitable for applications where the 700 mA current rating is sufficient and where the extended temperature range (-55°C to 125°C) or lower DC resistance (110 mOhm) provides design advantages. The ferrite drum core construction and lower DCR result in reduced power dissipation.

Both parts carry identical moisture sensitivity and REACH compliance status, ensuring equivalent handling and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can the Bourns SRR6603-220ML replace the Murata 23S220C in all applications?

A: Substitution is valid only when the application current requirement does not exceed 700 mA. If your circuit requires the full 800 mA rating, the Murata part is required.

Q: What is the impact of the different DC resistance values?

A: The Bourns part has 110 mOhm maximum DCR compared to Murata's 175 mOhm maximum. Lower DCR reduces resistive losses and heat generation. This is beneficial in most applications but does not affect inductance value or frequency response.

Q: Are the physical dimensions compatible with the same PCB layout?

A: The parts have different footprints. Murata measures 6.20mm L x 5.60mm W while Bourns measures 6.60mm L x 4.40mm W. PCB layout verification is required before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the difference between the core materials?

A: The Murata part uses an unspecified core material, while the Bourns SRR6603-220ML uses a ferrite drum core. Both achieve the same 22 µH inductance value and shielding performance.

Q: Can I use the Bourns part in applications requiring the extended temperature range?

A: Yes. The Bourns part operates from -55°C to 125°C, which exceeds the Murata range of -40°C to 85°C. If your application requires operation below -40°C or above 85°C, the Bourns part is suitable.
