Murata Power Solutions 23S100C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 23S100C is a 10 µH shielded wirewound inductor rated for 1.18 A with a maximum DC resistance of 87mOhm. This surface mount component operates across the temperature range of -40°C to 85°C and is classified as Active product status. Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit operation within the electrical and mechanical tolerances of alternative qualified inductors.

Key Parameters

Substitute Part Grouping Explanation

The Bourns Inc. SRR6603-100ML qualifies as a substitute based on the following alignment of critical parameters:

Matched Parameters:

• Inductance: 10 µH (identical)
• Shielding: Shielded (identical)
• Mounting Type: Surface Mount (identical)
• Package Type: Tape & Reel (TR) (identical)
• RoHS Status: ROHS3 Compliant (identical)

Acceptable Variance Parameters:

• Current Rating: 1 A (substitute) vs. 1.18 A (main part) — substitute operates within the main part's current envelope
• DC Resistance: 75mOhm Max (substitute) vs. 87mOhm Max (main part) — substitute exhibits lower resistance, maintaining performance margin
• Operating Temperature: -55°C ~ 125°C (substitute) vs. -40°C ~ 85°C (main part) — substitute provides extended temperature coverage

Parameter Comparison

Engineering Selection Recommendations

Both the 23S100C and SRR6603-100ML maintain Active product status and ROHS3 compliance. The SRR6603-100ML substitute is suitable for applications where the current requirement does not exceed 1 A and where the lower DC resistance of 75mOhm provides acceptable performance characteristics. The extended operating temperature range of the substitute (-55°C ~ 125°C) accommodates applications requiring broader thermal operation. Selection between these components should be based on circuit current requirements and thermal environment specifications.

Frequently Asked Questions (FAQ)

Q: Can the SRR6603-100ML replace the 23S100C in all applications?

A: The SRR6603-100ML is suitable for applications where circuit current does not exceed 1 A. If the design requires the full 1.18 A rating of the 23S100C, the substitute is not appropriate.

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

A: The SRR6603-100ML exhibits 75mOhm maximum DC resistance compared to 87mOhm maximum for the 23S100C. Lower DC resistance reduces power dissipation and heat generation in the inductor, which is beneficial for thermal performance.

Q: Are the physical dimensions compatible?

A: Both components are classified as Nonstandard package types and are surface mount devices. Physical dimensions differ slightly: 23S100C measures 0.244" L x 0.220" W x 0.126" H; SRR6603-100ML measures 0.260" L x 0.173" W x 0.118" H. PCB layout verification is required.

Q: Do both parts meet the same compliance standards?

A: Both components are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8504.50.4000).

Q: What is the difference in operating temperature ranges?

A: The 23S100C operates from -40°C to 85°C, while the SRR6603-100ML operates from -55°C to 125°C. The substitute provides extended low and high temperature capability.
