Murata Power Solutions 18223C 22µH Axial Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 18223C is a 22µH unshielded wirewound inductor rated for 2.42A continuous current with a maximum DC resistance of 25mOhm. This through-hole axial component operates across a 0°C to 70°C temperature range and is part of the 1800 series. The part is currently obsolete, making identification of functionally equivalent substitutes essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 18223C is determined by the following critical parameters:

• Inductance value: 22µH (exact match required)
• Tolerance: ±10% (matching tolerance specification)
• Shielding: Unshielded (same electromagnetic profile)
• Mounting type: Through hole axial configuration
• Current rating: Must meet or exceed 2.42A minimum
• DC resistance: Lower or equal to 25mOhm preferred for thermal performance

The two identified substitutes meet these core electrical and mechanical criteria while offering improved product status and expanded operating temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

The 18223C is obsolete and no longer in active production. Both substitute parts are currently active and available from their respective manufacturers.

The Bourns 5900-220-RC offers the highest current rating (3.8A) and lowest DC resistance relative to current capacity, with an extended operating temperature range of -55°C to 105°C. This part uses a ferrite drum core construction and is RoHS3 compliant.

The Abracon AIAP-02-220K provides a current rating of 2.7A with an operating temperature range of -40°C to 85°C. This wirewound inductor is also RoHS3 compliant and available in bulk packaging with the highest inventory availability (25,642 pieces).

Selection between these substitutes depends on application thermal requirements and current headroom needs. Both parts maintain the same inductance value, tolerance, and unshielded axial configuration as the original 18223C.

Frequently Asked Questions (FAQ)

Q: Can the 5900-220-RC or AIAP-02-220K be used as direct replacements for the 18223C?

A: Yes. Both substitutes maintain the same 22µH inductance value, ±10% tolerance, unshielded configuration, and through-hole axial mounting. Current ratings exceed or match the original 2.42A specification.

Q: What is the difference between the Bourns and Abracon substitutes?

A: The Bourns 5900-220-RC features a ferrite drum core with higher current capacity (3.8A) and lower DCR (30mOhm), suitable for applications requiring extended temperature operation (-55°C to 105°C). The Abracon AIAP-02-220K is a standard wirewound design with 2.7A current rating and operates from -40°C to 85°C.

Q: Does the higher DC resistance of the AIAP-02-220K affect compatibility?

A: The AIAP-02-220K has a maximum DCR of 50mOhm compared to the original 25mOhm. This increases resistive losses and heat generation. Selection should account for thermal budget and current profile in the application circuit.

Q: Are both substitutes RoHS compliant?

A: Yes. The Bourns 5900-220-RC is RoHS3 compliant. The Abracon AIAP-02-220K is RoHS3 compliant. Both parts are REACH unaffected.

Q: What are the physical size differences?

A: The 18223C measures 0.539" diameter × 0.719" length. The Bourns 5900-220-RC is 0.453" diameter × 0.900" length. The Abracon AIAP-02-220K is 0.252" diameter × 0.551" length. PCB layout and clearance requirements should be verified before substitution.
