Murata Power Solutions 18104C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 18104C is a 100 µH unshielded wirewound axial inductor rated for 1.2 A with a maximum DC resistance of 100 mOhm. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The part operates across a temperature range of 0°C to 70°C and is suitable for through-hole mounting applications requiring fixed inductance values in the 100 µH range.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 18104C are selected based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Inductance value: 100 µH (exact match required)
• Inductance tolerance: ±10% (matching tolerance band)
• Mounting type: Through hole axial configuration
• Package / case: Axial form factor
• Shielding: Unshielded construction

Secondary considerations include current rating capability, DC resistance characteristics, and operating temperature range. Substitute parts must maintain the same inductance specification and axial through-hole mounting configuration to ensure direct replacement compatibility in existing circuit designs.

Engineering Selection Recommendations

The Bourns 5900-101-RC and Abracon AIAP-02-101K are both active product alternatives to the obsolete Murata 18104C. Selection between these substitutes depends on specific application requirements:

The Bourns 5900-101-RC offers superior current handling capability at 2.2 A with lower DC resistance of 86 mOhm maximum, making it suitable for applications requiring higher current capacity or lower power dissipation. This part features a ferrite drum core construction and operates across an extended temperature range of -55°C to 105°C. The 5900-101-RC is RoHS3 compliant and available in tray packaging.

The Abracon AIAP-02-101K maintains the original 1.2 A current rating and provides a more compact physical footprint at 0.252" diameter compared to the original 0.539" diameter. This part is RoHS3 compliant and available in bulk packaging. The AIAP-02-101K operates across -40°C to 85°C, providing adequate temperature coverage for most standard applications.

Both substitute parts meet the core electrical requirements of 100 µH inductance with ±10% tolerance and unshielded axial through-hole mounting. Both are REACH unaffected and classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 5900-101-RC directly replace the Murata 18104C?

A: Yes. Both parts share identical inductance (100 µH), tolerance (±10%), shielding (unshielded), and axial through-hole mounting configuration. The Bourns part offers higher current rating (2.2 A vs 1.2 A) and lower DC resistance (86 mOhm vs 100 mOhm), making it electrically compatible and functionally superior for the same circuit application.

Q: Can the Abracon AIAP-02-101K directly replace the Murata 18104C?

A: Yes. Both parts share identical inductance (100 µH), tolerance (±10%), shielding (unshielded), and axial through-hole mounting configuration. The Abracon part maintains the same 1.2 A current rating as the original. Physical dimensions differ, with the AIAP-02-101K being more compact.

Q: What are the key differences between the two substitute options?

A: The Bourns 5900-101-RC provides higher current capacity (2.2 A) and lower DC resistance (86 mOhm), suitable for applications requiring enhanced power handling. The Abracon AIAP-02-101K maintains the original current specification (1.2 A) with a more compact form factor. Both are active products with current availability and compliance certifications.

Q: Are there physical dimension constraints I should consider?

A: Yes. The Murata 18104C measures 0.539" diameter × 0.719" length. The Bourns 5900-101-RC measures 0.453" diameter × 0.900" length. The Abracon AIAP-02-101K measures 0.252" diameter × 0.551" length. Verify PCB layout and component spacing before selection to ensure mechanical fit.

Q: What compliance certifications apply to these substitute parts?

A: Both the Bourns 5900-101-RC and Abracon AIAP-02-101K are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both meet the same regulatory requirements as the original Murata part.
