Murata Power Solutions 18106C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 18106C is a 10 mH unshielded wirewound axial inductor rated for 130 mA with a maximum DC resistance of 12 ohms. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. The 1800 series inductor provides fixed inductance suitable for through-hole mounting applications requiring moderate current handling and compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 18106C are selected based on the following critical parameters that must align with the original component:

Core Matching Criteria:

• Inductance value: 10 mH (fixed requirement)
• Inductance tolerance: ±10% (fixed requirement)
• Mounting type: Through Hole (fixed requirement)
• Package type: Axial (fixed requirement)
• Shielding: Unshielded (fixed requirement)

Performance Flexibility:

• Current rating: Substitute parts must meet or exceed 130 mA minimum
• DC resistance: Substitute parts may vary; lower DCR values are acceptable
• Operating temperature: Substitute parts must support the application's thermal requirements
• Regulatory compliance: RoHS and REACH status must be maintained

The identified substitutes meet all core matching criteria while offering improved or equivalent electrical performance characteristics.

Engineering Selection Recommendations

5900-103-RC (Bourns Inc., Active Status)

The Bourns 5900-103-RC is an active product with ROHS3 compliance and extended operating temperature range (-55°C to 105°C). This substitute provides superior current handling at 230 mA and reduced DC resistance at 7.6 ohms maximum, resulting in lower power dissipation. The drum core ferrite construction and saturation current specification of 260 mA provide additional design margin. Packaging in trays supports production environments requiring organized component handling.

AIAP-02-103K (Abracon LLC, Active Status)

The Abracon AIAP-02-103K is an active product with ROHS3 compliance and operating temperature range of -40°C to 85°C. This substitute meets the minimum current requirement at 140 mA and maintains RoHS compliance. The compact form factor (0.252" diameter × 0.551" length) offers space-saving advantages in applications where board real estate is constrained. Bulk packaging supports high-volume production requirements.

Both substitutes maintain regulatory compliance and support the electrical requirements of the obsolete 18106C while offering active product status and extended availability.

Frequently Asked Questions (FAQ)

Q: Can the 5900-103-RC replace the 18106C in all applications?

A: The 5900-103-RC meets all core electrical and mechanical requirements for substitution. The reduced DC resistance (7.6 ohms vs. 12 ohms) and higher current rating (230 mA vs. 130 mA) provide improved performance margins. Extended operating temperature range (-55°C to 105°C) supports broader thermal environments. Physical dimensions differ slightly; verify board layout compatibility before implementation.

Q: What are the physical dimension differences between substitutes?

A: The 18106C measures 0.539" diameter × 0.719" length. The 5900-103-RC measures 0.453" diameter × 0.900" length, offering a smaller diameter but greater axial length. The AIAP-02-103K measures 0.252" diameter × 0.551" length, providing the most compact form factor. Verify mounting hole spacing and clearance requirements for your specific application.

Q: Are both substitutes RoHS compliant?

A: Yes. The 18106C carries RoHS Compliant status. Both substitutes carry ROHS3 Compliant status, which represents current RoHS directive compliance. REACH status is unaffected for all three parts.

Q: Which substitute offers the lowest power dissipation?

A: The 5900-103-RC provides the lowest DC resistance at 7.6 ohms maximum, resulting in the lowest power dissipation at equivalent current levels. The AIAP-02-103K exhibits higher DC resistance at 26.4 ohms maximum, which may increase power dissipation in current-limited applications.

Q: Can the AIAP-02-103K be used if the 5900-103-RC is unavailable?

A: The AIAP-02-103K meets all core substitution criteria and maintains active product status. However, the higher DC resistance (26.4 ohms vs. 12 ohms) will increase power dissipation. Verify thermal performance and current handling requirements for your specific circuit before selection.
