AX104R-151 Equivalent & Substitute Parts

Part Overview

The AX104R-151 is a 150 µH shielded drum core, wirewound inductor manufactured by Triad Magnetics, designed for surface mount applications. This component operates at 1.15 A maximum current with a DC resistance of 506mOhm and is rated for operating temperatures from -40°C to 85°C. The part maintains Active product status with 1065 units available in new original stock.

Equivalent and substitute parts are identified to provide design flexibility when the primary component is unavailable, when alternative packaging formats are required, or when procurement from multiple suppliers is necessary for supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX104R-151 is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 150 µH (exact match required)
• Inductance tolerance: ±30% (matching tolerance specification)
• Core type: Ferrite drum core, wirewound construction
• Shielding: Shielded configuration
• Mounting: Surface mount technology

Secondary Compatibility Criteria:

• Current rating: Substitute must support minimum 1.15 A operation
• DC resistance: Substitute DCR must not exceed 506mOhm to maintain circuit performance
• Operating temperature: Substitute must cover the -40°C to 85°C range or broader
• Regulatory compliance: ROHS3 compliance required

The SRU1048-151Y from Bourns Inc. qualifies as a substitute based on matching inductance (150 µH), identical tolerance (±30%), ferrite drum core construction, shielded design, and surface mount packaging. The substitute exhibits lower DC resistance (235mOhm) and higher current saturation rating (800mA), providing improved electrical performance characteristics within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (AX104R-151): The AX104R-151 maintains Active product status with established supply availability (1065 units in stock). This component is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Selection is appropriate for applications requiring box packaging format and the specified -40°C to 85°C operating window.

Substitute Component (SRU1048-151Y): The SRU1048-151Y is suitable for applications where Tape & Reel packaging is preferred for automated assembly processes. This substitute provides superior electrical characteristics with 235mOhm DCR (compared to 506mOhm) and an extended operating temperature range to 125°C. The substitute maintains ROHS3 compliance and REACH unaffected status. Current rating of 1.0 A is lower than the primary component's 1.15 A specification; circuit design must confirm that 1.0 A maximum current satisfies application requirements.

Both components share identical inductance (150 µH), tolerance (±30%), ferrite core construction, shielded configuration, and surface mount technology, establishing direct functional equivalence within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can the SRU1048-151Y directly replace the AX104R-151 in existing designs?

A: Direct replacement is possible when the application current requirement does not exceed 1.0 A. The SRU1048-151Y's lower DC resistance (235mOhm vs. 506mOhm) and extended temperature rating to 125°C provide equivalent or improved performance. Verify that your circuit design operates within the 1.0 A maximum current specification of the substitute.

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

A: The primary differences are current rating (AX104R-151: 1.15 A; SRU1048-151Y: 1.0 A), DC resistance (AX104R-151: 506mOhm; SRU1048-151Y: 235mOhm), operating temperature upper limit (AX104R-151: 85°C; SRU1048-151Y: 125°C), and packaging format (AX104R-151: Box; SRU1048-151Y: Tape & Reel). Inductance value and tolerance are identical.

Q: Are both components RoHS compliant?

A: Yes, both the AX104R-151 and SRU1048-151Y are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Does packaging format affect electrical performance?

A: No. Box and Tape & Reel packaging formats do not affect electrical performance. Packaging selection is determined by assembly process requirements and inventory management preferences.

Q: What is the significance of the ±30% inductance tolerance?

A: The ±30% tolerance indicates that the actual inductance value may vary between 105 µH and 195 µH. Both the primary and substitute components share this tolerance specification, ensuring equivalent inductance accuracy for circuit design purposes.

Q: Can I use the SRU1048-151Y if my application requires 1.15 A operation?

A: No. The SRU1048-151Y is rated for maximum 1.0 A continuous current. Applications requiring 1.15 A operation must use the AX104R-151 or identify alternative components with higher current ratings.
