AX97-10330 Equivalent & Substitute Parts

Part Overview

The AX97-10330 is a 33 µH unshielded drum core wirewound inductor manufactured by Triad Magnetics, designed for surface mount applications. This component is rated for 570 mA continuous current with a maximum DC resistance of 690 mOhm and operates across the temperature range of -40°C to 85°C. The part is currently active in production and ROHS3 compliant.

Substitute parts are identified when equivalent inductance values, current ratings, and core materials are available from alternative manufacturers, enabling procurement flexibility and supply chain continuity while maintaining circuit performance within specified tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the AX97-10330 is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 33 µH (within ±20% tolerance band)
• Core material: Ferrite
• Core type: Drum core, wirewound construction
• Mounting type: Surface mount
• Current rating: Equal to or greater than 570 mA
• DC resistance: Equal to or lower than 690 mOhm
• Operating temperature range: Must encompass or exceed -40°C to 85°C
• Compliance: ROHS3 compliant

The SRR6603-330ML from Bourns Inc. qualifies as a substitute based on matching inductance, core material, core type, and mounting configuration. The substitute demonstrates superior electrical performance with higher current rating (600 mA versus 570 mA) and significantly lower DC resistance (190 mOhm versus 690 mOhm maximum). The substitute's extended operating temperature range (-55°C to 125°C) encompasses the original part's specification.

Engineering Selection Recommendations

AX97-10330 (Primary Selection): The AX97-10330 remains the specified component when the original design calls for an unshielded inductor configuration. This part is active in production, ROHS3 compliant, and maintains full compatibility with existing bill of materials and PCB layouts.

SRR6603-330ML (Substitute Selection): The SRR6603-330ML is suitable as a substitute when supply constraints affect AX97-10330 availability. The substitute provides measurable performance improvements: 30 mA additional current margin, 500 mOhm lower DC resistance, and extended temperature operating range. The shielded construction of the SRR6603-330ML provides electromagnetic interference mitigation not present in the unshielded AX97-10330. Both parts maintain ROHS3 compliance and ferrite core construction.

Packaging Consideration: The AX97-10330 is supplied in Box packaging, while the SRR6603-330ML is supplied in Tape & Reel format. Procurement and assembly processes must accommodate this packaging difference.

Frequently Asked Questions (FAQ)

Q: Can the SRR6603-330ML directly replace the AX97-10330 in my circuit?

A: The SRR6603-330ML is electrically compatible as a substitute. Both components share identical 33 µH inductance values, ±20% tolerance, ferrite drum core construction, and surface mount configuration. The substitute's superior current rating and lower DC resistance provide performance margin. The primary design consideration is the shielded versus unshielded core difference; the SRR6603-330ML's shielding may alter electromagnetic coupling characteristics in sensitive applications.

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

A: The AX97-10330 specifies 690 mOhm maximum DC resistance, while the SRR6603-330ML specifies 190 mOhm maximum. Lower DC resistance reduces resistive losses and heat generation in the inductor. For circuits where the AX97-10330's 690 mOhm specification was a design constraint, the SRR6603-330ML's 190 mOhm provides significant improvement in efficiency and thermal performance.

Q: Are there temperature range implications for substitution?

A: The AX97-10330 operates from -40°C to 85°C, while the SRR6603-330ML operates from -55°C to 125°C. If your application requires operation at temperatures below -40°C or above 85°C, the SRR6603-330ML extends the usable range. For applications within the AX97-10330's specified range, both parts are functionally equivalent from a temperature perspective.

Q: Does the shielded construction of the SRR6603-330ML affect PCB layout?

A: Shielded inductors have different electromagnetic field distributions compared to unshielded designs. The SRR6603-330ML's shielding reduces radiated emissions and susceptibility to external magnetic fields. PCB layout modifications may be necessary if the original design relied on specific coupling or field characteristics of the unshielded AX97-10330. Physical dimensions also differ slightly: AX97-10330 is 7.30mm × 4.78mm × 3.23mm (max height), while SRR6603-330ML is 6.60mm × 4.40mm × 3.00mm (max height).

Q: What packaging format should I specify for procurement?

A: The AX97-10330 is supplied in Box packaging. The SRR6603-330ML is supplied in Tape & Reel format. Verify your assembly process compatibility with Tape & Reel packaging before selecting the substitute. Tape & Reel format is standard for automated pick-and-place assembly; Box packaging may require manual handling or special processing.

Q: Are both parts ROHS3 compliant?

A: Yes, both the AX97-10330 and SRR6603-330ML are ROHS3 compliant, meeting the same environmental and hazardous substance restrictions. Both parts are also REACH unaffected and classified under ECCN EAR99.
