Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX104R-1R5 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 1.5 µH (within ±30% tolerance specification)
• Core type: Ferrite drum core wirewound construction
• Shielding: Shielded configuration
• Mounting: Surface mount technology
• Current rating: Equal to or greater than 6.5 A
• DC resistance: Equal to or lower than 8.1 mOhm
• Operating temperature: Minimum range of -40°C to 85°C
• Regulatory compliance: ROHS3 Compliant

The SRU1048-1R5Y from Bourns Inc. qualifies as a direct substitute based on matching inductance, core material, shielding, and surface mount configuration. The substitute demonstrates superior electrical performance with higher current rating (7 A) and lower DC resistance (4.3 mOhm), while maintaining full regulatory compliance.

Engineering Selection Recommendations

AX104R-1R5 Selection Criteria:

• Primary source availability with 1162 units in stock
• Box packaging suitable for low-volume or prototype applications
• Meets all regulatory requirements (ROHS3 Compliant, REACH Unaffected)
• Active product status ensures continued manufacturer support

SRU1048-1R5Y Selection Criteria:

• Extended operating temperature range (-40°C to 125°C) for applications requiring higher thermal margin
• Superior electrical performance: 7 A current rating and 4.3 mOhm DC resistance provide lower power dissipation
• Tape & Reel packaging optimized for high-volume production assembly
• Higher inventory availability (14412 units) supports sustained supply
• Active product status with full regulatory compliance (ROHS3 Compliant, REACH Unaffected)

Both components satisfy the core electrical and mechanical requirements for 1.5 µH shielded surface mount inductor applications. Selection between them depends on packaging requirements, thermal operating conditions, and production volume considerations.

Frequently Asked Questions (FAQ)

Q: Can the SRU1048-1R5Y directly replace the AX104R-1R5 in existing designs?

A: Yes. Both inductors share identical inductance values (1.5 µH), tolerance specifications (±30%), core material (ferrite), shielding configuration, and surface mount mounting type. The SRU1048-1R5Y provides equal or superior performance across all critical electrical parameters.

Q: What are the physical dimension differences between these parts?

A: The AX104R-1R5 measures 10.40mm L × 10.30mm W × 4.00mm H (seated). The SRU1048-1R5Y measures 10.00mm L × 10.00mm W × 5.10mm H (seated). Both are nonstandard package sizes. Verify PCB layout clearance for the SRU1048-1R5Y due to increased height.

Q: How do the DC resistance values affect circuit performance?

A: The SRU1048-1R5Y exhibits 4.3 mOhm DC resistance compared to the AX104R-1R5 at 8.1 mOhm maximum. Lower DC resistance reduces resistive losses and heat generation, particularly beneficial in high-current applications. This represents approximately 47% lower resistance.

Q: Are there temperature range limitations for substitution?

A: The AX104R-1R5 operates from -40°C to 85°C. The SRU1048-1R5Y extends to -40°C to 125°C. For applications within the -40°C to 85°C window, both are equivalent. For applications exceeding 85°C, only the SRU1048-1R5Y is suitable.

Q: What packaging considerations apply to high-volume production?

A: The AX104R-1R5 is supplied in Box packaging, suitable for manual assembly or low-volume pick-and-place operations. The SRU1048-1R5Y is supplied in Tape & Reel (TR) format, optimized for automated surface mount assembly lines and high-volume manufacturing.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the AX104R-1R5 and SRU1048-1R5Y are ROHS3 Compliant and REACH Unaffected, meeting equivalent environmental and regulatory requirements for commercial and industrial applications.
