AX104R-220 Equivalent & Substitute Parts

Part Overview

The AX104R-220 is a 22 µH shielded drum core wirewound inductor manufactured by Triad Magnetics, rated for 2.9 A continuous current with a maximum DC resistance of 73 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 858 pieces available in inventory.

Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while meeting the same functional requirements. Alternative components may be necessary due to inventory availability, lead time considerations, or specific application constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX104R-220 is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value of 22 µH within ±30% tolerance
• Current rating equal to or greater than 2.9 A
• DC resistance not exceeding 73 mOhm
• Ferrite drum core construction with shielding
• Inductance measured at 100 kHz test frequency

Mechanical & Environmental Criteria:

• Surface mount package configuration
• Operating temperature range compatible with -40°C to 85°C minimum
• Nonstandard package case type
• RoHS3 compliance

Compliance Criteria:

• REACH Unaffected status
• EAR99 export classification

The SRU1048-220Y from Bourns Inc. meets these substitution criteria with equivalent inductance and shielding characteristics, though with differing current ratings and DC resistance specifications.

Parameter Comparison

Engineering Selection Recommendations

AX104R-220 Selection Criteria:

• Applications requiring current capacity of 2.9 A
• Designs with thermal constraints limited to 85°C maximum operating temperature
• Circuits where higher DC resistance (73 mOhm) is acceptable
• Standard packaging in box format

SRU1048-220Y Selection Criteria:

• Applications with current requirements of 2.6 A or lower
• Designs benefiting from extended operating temperature range to 125°C
• Circuits where lower DC resistance (42 mOhm) provides performance advantage
• Tape & Reel packaging for automated assembly processes
• Higher inventory availability (5349 pieces in stock)

Both components maintain ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements for equivalent applications. The SRU1048-220Y provides superior thermal performance and lower resistive losses, while the AX104R-220 supports higher current loads.

Frequently Asked Questions (FAQ)

Q: Can the SRU1048-220Y replace the AX104R-220 in all applications?

A: The SRU1048-220Y is suitable for applications where the current requirement does not exceed 2.6 A. If your circuit requires the full 2.9 A rating of the AX104R-220, the substitute part will not provide adequate current capacity. Both parts share identical inductance values and tolerance specifications.

Q: What is the impact of different DC resistance values?

A: The AX104R-220 has a maximum DC resistance of 73 mOhm, while the SRU1048-220Y measures 42 mOhm. Lower DC resistance reduces power dissipation and heat generation in the inductor. Selection depends on whether your circuit design can accommodate the higher resistive losses of the AX104R-220.

Q: Are there packaging compatibility issues between these parts?

A: The AX104R-220 uses box packaging, while the SRU1048-220Y is supplied in Tape & Reel format. Both are surface mount components with similar footprints (10.40mm x 10.30mm versus 10.00mm x 10.00mm), though height differs (4.00mm versus 5.10mm). Verify PCB layout clearance for the taller SRU1048-220Y component.

Q: Which part should I select for high-temperature applications?

A: The SRU1048-220Y supports operating temperatures to 125°C, compared to 85°C for the AX104R-220. For applications exceeding 85°C, the SRU1048-220Y is the appropriate selection, provided current requirements do not exceed 2.6 A.

Q: Are both parts compliant with current regulations?

A: Both the AX104R-220 and SRU1048-220Y are ROHS3 compliant and REACH Unaffected. Both carry EAR99 export classification. They meet equivalent regulatory requirements for industrial and commercial applications.
