15103C Equivalent & Substitute Parts

Part Overview

The 15103C is a 10 µH unshielded wirewound inductor manufactured by Murata Power Solutions Inc., rated for 9.01 A continuous current with a maximum DC resistance of 10.6mOhm. This through-hole radial component operates across the -40°C to 85°C temperature range and is classified as Active product status with full ROHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this inductance value and current rating category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 15103C is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value: 10 µH (±10% tolerance band)
• Current rating: minimum 9 A continuous
• DC resistance: maximum 10mOhm to 10.6mOhm range
• Unshielded configuration

Mechanical Compatibility Criteria:

• Through-hole mounting type
• Radial, vertical cylinder package orientation
• Physical dimensions within acceptable tolerance (0.660" to 0.661" diameter; 0.839" to 0.840" height)

Compliance & Status Criteria:

• Active product status
• ROHS3 compliance
• REACH unaffected classification

The 1110-100K-RC from Bourns Inc. meets all substitution criteria within these parameter boundaries.

Parameter Comparison

Engineering Selection Recommendations

Both the 15103C and 1110-100K-RC are Active status components with ROHS3 compliance and REACH unaffected classification. The 1110-100K-RC provides an extended operating temperature range (-55°C to 105°C) compared to the 15103C (-40°C to 85°C), offering broader environmental coverage. Current ratings are equivalent within specification (9 A vs 9.01 A). DC resistance values are within acceptable substitution parameters (10mOhm vs 10.6mOhm maximum). Physical dimensions are interchangeable for through-hole radial mounting applications. Selection between these parts should be based on specific application temperature requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 1110-100K-RC directly replace the 15103C in existing designs?

A: Yes, within the specified electrical and mechanical parameters. Both components share identical inductance (10 µH), tolerance (±10%), equivalent current ratings (9 A vs 9.01 A), compatible DC resistance specifications, and identical through-hole radial mounting configuration. Physical dimensions are within acceptable tolerance for PCB footprint compatibility.

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

A: The primary differences are manufacturer (Murata vs Bourns), core material type (unspecified vs ferrite drum core), operating temperature range (15103C: -40°C to 85°C; 1110-100K-RC: -55°C to 105°C), and inductance test frequency (15103C: 10 kHz; 1110-100K-RC: 1 kHz). Electrical performance at rated specifications remains equivalent.

Q: Are both parts suitable for high-temperature applications?

A: The 1110-100K-RC supports operation to 105°C, making it suitable for extended temperature environments. The 15103C is rated to 85°C maximum. Application temperature requirements should determine part selection.

Q: Do these inductors have identical package dimensions?

A: Dimensions are functionally equivalent for PCB mounting. The 15103C measures 0.661" diameter × 0.839" height; the 1110-100K-RC measures 0.660" diameter × 0.840" height. These variations are within standard manufacturing tolerance and do not affect through-hole radial mounting compatibility.

Q: Are both parts RoHS compliant?

A: Yes, both the 15103C and 1110-100K-RC are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
