Murata 23S680C Equivalent & Substitute Parts

Part Overview

The Murata 23S680C is a 68 µH shielded wirewound inductor rated for 450 mA continuous current with a maximum DC resistance of 641 mOhm. 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. Substitute parts are identified when equivalent inductance values, shielding characteristics, and current handling capabilities align within acceptable operational parameters for the target application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Murata 23S680C is determined by the following critical parameters:

• Inductance Value: Must match 68 µH specification
• Shielding Type: Must be shielded to maintain electromagnetic containment
• Mounting Configuration: Must support surface mount assembly
• Current Rating: Substitute must support minimum 400 mA continuous current
• DC Resistance: Lower DCR values are acceptable; higher values require application verification
• Compliance: RoHS3 compliance required for regulatory alignment
• Temperature Range: Operating range must encompass application requirements

The Bourns SRR6603-680ML meets these substitution criteria with matching inductance, shielded construction, and surface mount compatibility. The substitute exhibits lower DC resistance (290 mOhm vs. 641 mOhm), which provides improved efficiency characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the Murata 23S680C and Bourns SRR6603-680ML are Active status components with full RoHS3 compliance and REACH unaffected designation. The Bourns substitute provides superior DC resistance performance at 290 mOhm compared to the Murata specification of 641 mOhm, resulting in reduced power dissipation in equivalent current conditions. The Bourns component supports an extended operating temperature range (-55°C to 125°C) versus the Murata range (-40°C to 85°C), offering broader thermal envelope compatibility. Current rating differential (400 mA vs. 450 mA) requires application-level verification to confirm adequate margin for the target circuit. Both components maintain shielded construction and surface mount configuration, ensuring mechanical and electromagnetic compatibility within the assembly footprint constraints.

Frequently Asked Questions (FAQ)

Q: Can the Bourns SRR6603-680ML directly replace the Murata 23S680C in all applications?

A: Direct substitution is valid when the application current requirement does not exceed 400 mA. The 50 mA current rating reduction must be evaluated against circuit design margins. The lower DC resistance of the Bourns component provides improved efficiency and reduced thermal generation.

Q: What is the significance of the DC resistance difference between these parts?

A: The Murata 23S680C specifies 641 mOhm maximum DC resistance, while the Bourns SRR6603-680ML specifies 290 mOhm maximum. Lower DC resistance reduces I²R power losses in the inductor. At 400 mA, the Murata dissipates approximately 103 mW maximum, while the Bourns dissipates approximately 46 mW maximum under identical current conditions.

Q: Are the physical dimensions compatible for PCB layout?

A: The Murata 23S680C measures 6.20mm L × 5.60mm W × 3.20mm H (seated). The Bourns SRR6603-680ML measures 6.60mm L × 4.40mm W × 3.00mm H (seated). Dimensional differences require PCB footprint verification to confirm mechanical fit within the target assembly space.

Q: Do both components support the same operating temperature range?

A: No. The Murata 23S680C operates from -40°C to 85°C, while the Bourns SRR6603-680ML operates from -55°C to 125°C. The Bourns component supports extended thermal operation and is suitable for applications requiring broader temperature envelope coverage.

Q: What compliance certifications apply to both components?

A: Both the Murata 23S680C and Bourns SRR6603-680ML are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8504.50.4000. Both components carry Moisture Sensitivity Level 1 (Unlimited) rating.
