AX104R-6R8 Equivalent & Substitute Parts

Part Overview

The AX104R-6R8 is a 6.8 µH shielded drum core wirewound inductor manufactured by Triad Magnetics, rated for 4.8 A continuous current with a maximum DC resistance of 19.5 mOhm. This surface mount component operates across the temperature range of -40°C to 85°C and is ROHS3 compliant. The part is currently in active production status with 974 pieces available in new original inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across critical parameters including inductance value, current rating, shielding type, core material, and surface mount packaging specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX104R-6R8 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value: 6.8 µH at 100 kHz test frequency
• Inductance tolerance: ±30%
• Current rating: 4.8 A minimum
• Core material: Ferrite
• Shielding: Shielded configuration

Mechanical Equivalence Requirements:

• Mounting type: Surface mount
• Package type: Nonstandard drum core form factor
• Core construction: Wirewound drum core

Compliance Requirements:

• ROHS3 compliance
• Operating temperature compatibility

The SRU1048-6R8Y from Bourns Inc. meets all electrical and mechanical equivalence criteria and qualifies as a direct substitute based on these parameters.

Engineering Selection Recommendations

AX104R-6R8 Selection Criteria:

• Primary choice when box packaging is required for component handling and storage
• Suitable for applications operating within -40°C to 85°C temperature range
• ROHS3 compliance satisfies regulatory requirements for restricted substance control

SRU1048-6R8Y Selection Criteria:

• Preferred when tape and reel packaging is required for automated assembly processes
• Extended operating temperature range (-40°C to 125°C) accommodates higher temperature environments
• Lower DC resistance (13.6 mOhm versus 19.5 mOhm) reduces resistive losses in the inductor
• Higher inventory availability (17500 pieces) supports larger production volumes
• ROHS3 compliance maintains regulatory equivalence

Both parts satisfy REACH unaffected status and EAR99 export classification. Selection between these parts depends on packaging requirements, temperature operating range, and loss characteristics specific to the application circuit.

Frequently Asked Questions (FAQ)

Q: Can SRU1048-6R8Y replace AX104R-6R8 in all applications?

A: The SRU1048-6R8Y meets all critical electrical parameters (6.8 µH inductance, 4.8 A current rating, ferrite shielded core) and mechanical requirements (surface mount, nonstandard drum core package). Substitution is valid for applications operating within the overlapping temperature range of -40°C to 85°C. Applications requiring operation above 85°C benefit from the extended temperature rating of the SRU1048-6R8Y.

Q: What is the difference in DC resistance between these parts?

A: The AX104R-6R8 specifies a maximum DC resistance of 19.5 mOhm, while the SRU1048-6R8Y has a DC resistance of 13.6 mOhm. The lower resistance of the substitute part results in reduced resistive losses and lower heat generation during operation at rated current.

Q: Are the physical dimensions compatible?

A: The parts have similar but not identical dimensions. The AX104R-6R8 measures 10.40mm L x 10.30mm W x 4.00mm H (seated), while the SRU1048-6R8Y measures 10.00mm L x 10.00mm W x 5.10mm H (seated). PCB layout and component placement clearances must be verified before substitution.

Q: What packaging differences exist?

A: The AX104R-6R8 is supplied in box packaging, while the SRU1048-6R8Y is supplied in tape and reel format. Box packaging is suitable for manual assembly and small-volume applications. Tape and reel packaging is optimized for automated pick-and-place assembly processes.

Q: Are both parts RoHS compliant?

A: Both the AX104R-6R8 and SRU1048-6R8Y are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for restricted substance control in electronic components.
