Murata Power Solutions 15104C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 15104C is a 100 µH unshielded wirewound inductor rated for 2.62 A continuous current with a maximum DC resistance of 110mOhm. This through-hole radial component operates across the -40°C to 85°C temperature range and is classified as Active product status. Substitute parts are identified when equivalent inductance values, current ratings, and mechanical dimensions align within acceptable engineering tolerances, enabling direct replacement in circuit applications where the original part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 15104C is determined by the following critical parameters:

• Inductance Value: 100 µH ±10% tolerance
• Current Rating: Minimum 2.62 A continuous current capability
• DC Resistance: Maximum 110mOhm to maintain equivalent power dissipation characteristics
• Mounting Type: Through Hole configuration
• Package / Case: Radial, Vertical Cylinder form factor
• Mechanical Dimensions: Diameter and height within manufacturing tolerances to ensure PCB footprint compatibility
• Shielding Classification: Unshielded topology

The Bourns Inc. 1110-101K-RC meets these substitution criteria with equivalent inductance, superior current rating (2.8 A), lower DC resistance (95mOhm), and compatible mechanical dimensions. Both parts maintain ROHS3 compliance and unshielded construction.

Parameter Comparison

Engineering Selection Recommendations

The Bourns Inc. 1110-101K-RC qualifies as a direct substitute for the Murata Power Solutions 15104C based on electrical and mechanical parameter alignment. Both components maintain Active product status and ROHS3 compliance. The substitute part provides enhanced performance characteristics: 7% higher current rating (2.8 A vs. 2.62 A) and 14% lower DC resistance (95mOhm vs. 110mOhm), resulting in reduced thermal dissipation in equivalent circuit applications. Mechanical dimensions remain within manufacturing tolerances for PCB footprint compatibility. The extended operating temperature range (-55 to 105°C) of the substitute part accommodates broader environmental specifications without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 1110-101K-RC replace the Murata 15104C in existing designs?

A: Yes. Both inductors provide 100 µH inductance with ±10% tolerance, through-hole radial mounting, and compatible mechanical dimensions. The substitute part meets or exceeds all critical electrical parameters.

Q: What are the key differences between these two inductors?

A: The primary differences are manufacturer (Murata vs. Bourns), core material (unspecified vs. ferrite drum core), current rating (2.62 A vs. 2.8 A), and DC resistance (110mOhm vs. 95mOhm). The Bourns part offers superior current handling and lower resistance characteristics.

Q: Are there packaging differences between these parts?

A: The Murata 15104C is supplied in Tray packaging, while the Bourns 1110-101K-RC is supplied in Bulk packaging. Both maintain identical through-hole radial form factors and PCB footprint compatibility.

Q: Do both parts meet regulatory compliance requirements?

A: Yes. Both the Murata 15104C and Bourns 1110-101K-RC are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What is the inductance frequency test specification for each part?

A: The Murata 15104C is tested at 10 kHz, while the Bourns 1110-101K-RC is tested at 1 kHz. Both maintain the specified 100 µH inductance value within their respective test conditions.
