Murata Power Solutions 18153C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 18153C is a 15 µH unshielded wirewound inductor rated for 3 A with a maximum DC resistance of 18mOhm, designed for through-hole axial mounting. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and production continuity. The 1800 series inductor serves applications requiring fixed inductance values with moderate current handling and low DC resistance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 18153C must satisfy the following electrical and mechanical criteria:

• Inductance value of 15 µH with ±10% tolerance
• Through-hole axial mounting configuration
• Unshielded construction
• Current rating equal to or greater than 3 A
• DC resistance within acceptable limits for the application

The two identified substitute parts meet these core requirements while offering enhanced specifications in certain parameters. Substitution is valid when the application circuit can accommodate the electrical characteristics of the alternative component.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support, addressing the obsolescence status of the 18153C.

The Bourns 5900-150-RC offers the lowest DC resistance at 25mOhm Max and the highest current rating at 4.2 A, with an extended operating temperature range of -55°C ~ 105°C. This part is ROHS3 compliant and features a ferrite drum core construction. The slightly increased DCR and larger physical dimensions (0.453" Dia x 0.900" L) must be evaluated against PCB layout constraints.

The Abracon AIAP-02-150K provides a current rating of 3.3 A with a more compact form factor (0.252" Dia x 0.551" L), closely matching the original 18153C specifications. However, the DCR of 40mOhm Max represents a significant increase from the original 18mOhm specification and may impact circuit performance in applications sensitive to inductor losses. This part is ROHS3 compliant with an operating temperature range of -40°C ~ 85°C.

Selection between these substitutes depends on circuit requirements for current headroom, thermal performance, and DC resistance tolerance.

Frequently Asked Questions (FAQ)

Q: Can the 5900-150-RC be used as a direct replacement for the 18153C?

A: The 5900-150-RC meets the core electrical requirements of 15 µH inductance and exceeds the current rating specification. The increased DCR of 25mOhm versus 18mOhm must be evaluated for circuit impact. Physical dimensions differ slightly, requiring PCB layout verification.

Q: What is the impact of higher DC resistance in the AIAP-02-150K?

A: The AIAP-02-150K DCR of 40mOhm Max is 2.2 times higher than the original 18153C specification. In circuits where inductor losses directly affect efficiency or thermal performance, this increase may be unacceptable. Applications with less stringent loss requirements can tolerate this parameter.

Q: Are both substitute parts RoHS compliant?

A: Yes, both the Bourns 5900-150-RC and Abracon AIAP-02-150K are ROHS3 compliant, meeting current environmental regulations.

Q: How do the physical dimensions affect PCB design?

A: The 18153C measures 0.539" Dia x 0.719" L. The Bourns substitute is slightly larger at 0.453" Dia x 0.900" L, while the Abracon substitute is significantly smaller at 0.252" Dia x 0.551" L. PCB footprint and component spacing must be verified for each alternative.

Q: What temperature range should be considered for system design?

A: The original 18153C operates from 0°C ~ 70°C. The Bourns 5900-150-RC extends this to -55°C ~ 105°C, and the Abracon AIAP-02-150K to -40°C ~ 85°C. System thermal requirements determine which operating range is appropriate.
