Murata Power Solutions 26180C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 26180C is an 18 µH unshielded wirewound inductor rated for 2.1 A continuous current with a maximum DC resistance of 87 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 is currently active in production and maintains full RoHS3 compliance. Equivalent and substitute parts are identified when design requirements permit tolerance in electrical performance or when supply chain considerations necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 26180C is permissible when the alternative component maintains the following critical parameters within acceptable engineering tolerances:

• Inductance value of 18 µH at 1 kHz test frequency
• Current rating equal to or greater than 2.1 A
• DC resistance not exceeding 90 mOhm (allowing for minor variation in loss characteristics)
• Unshielded configuration to maintain electromagnetic compatibility with the original design
• Surface mount capability with compatible physical dimensions
• Operating temperature range that encompasses or exceeds -40°C to 85°C
• RoHS3 compliance and equivalent regulatory status

The Bourns SDR1006-180ML satisfies these substitution criteria through equivalent inductance, superior current rating (2.15 A), comparable DC resistance (90 mOhm Max), and extended operating temperature range (-40°C to 125°C).

Parameter Comparison

Engineering Selection Recommendations

Both the 26180C and SDR1006-180ML are active production components with full RoHS3 compliance and REACH unaffected status. The SDR1006-180ML provides equivalent inductance with a marginal increase in current rating (2.15 A versus 2.1 A) and DC resistance (90 mOhm versus 87 mOhm). The extended operating temperature range of the Bourns component (-40°C to 125°C) offers additional thermal margin beyond the Murata specification. Selection between these parts should be based on availability, lead time, and specific application thermal requirements. Both components meet the regulatory and compliance requirements for industrial surface mount inductor applications.

Frequently Asked Questions (FAQ)

Q: Can the SDR1006-180ML replace the 26180C in all applications?

A: The SDR1006-180ML is electrically compatible for applications where the 26180C is specified, provided the design does not depend on the specific self-resonant frequency characteristic (19 MHz for 26180C versus 15 MHz for SDR1006-180ML). Physical footprint verification is required due to nonstandard package dimensions.

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

A: The DC resistance difference of 3 mOhm (87 mOhm versus 90 mOhm) represents a 3.4% variation. This minor difference is acceptable in most inductor applications and does not constitute a functional incompatibility.

Q: Are there any temperature-related considerations for substitution?

A: The SDR1006-180ML operates to 125°C, exceeding the 26180C specification of 85°C. Applications operating within the 26180C temperature range are fully compatible with the substitute part. Applications requiring operation above 85°C benefit from the extended thermal capability of the Bourns component.

Q: How do the package dimensions compare?

A: The 26180C measures 10.00mm L x 9.00mm W x 5.80mm H. The SDR1006-180ML measures 9.80mm L x 9.80mm W x 5.80mm H. Both are nonstandard packages with similar height. Physical layout verification is necessary to confirm PCB footprint compatibility.

Q: What certifications apply to both parts?

A: Both components are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8504.50.4000. Moisture sensitivity level is 1 (Unlimited) for both parts.
