AX97-10680 Equivalent & Substitute Parts Reference

Part Overview

The AX97-10680 is a 68 µH unshielded drum core wirewound inductor manufactured by Triad Magnetics, rated for 370 mA continuous current with a maximum DC resistance of 1.39 Ohm. This surface mount component operates across the temperature range of -40°C to 85°C and is specified for 100 kHz inductance testing. The part is currently active in production and ROHS3 compliant, making it suitable for modern electronic applications requiring fixed inductance filtering, energy storage, or signal conditioning in power conversion and RF circuits.

Equivalent and substitute parts are identified when alternative components maintain the same inductance value, tolerance, and core material while accommodating variations in current rating, DC resistance, shielding configuration, and package dimensions within acceptable engineering parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX97-10680 is determined by the following critical parameters:

Primary Matching Criteria (Non-Negotiable):

• Inductance value: 68 µH
• Inductance tolerance: ±20%
• Core material: Ferrite
• Core type: Drum core, wirewound
• Mounting type: Surface mount
• RoHS compliance: ROHS3 Compliant

Secondary Compatibility Parameters (Allowable Variation):

• Current rating: Substitute must equal or exceed 370 mA
• DC resistance: Substitute must not exceed 1.39 Ohm (lower values acceptable)
• Shielding: May differ based on application requirements
• Operating temperature range: Substitute must encompass or exceed -40°C to 85°C
• Package dimensions: Nonstandard packages acceptable if footprint compatible

The SRR6603-680ML from Bourns Inc. qualifies as a direct substitute based on matching inductance, tolerance, core material, core type, and mounting configuration. The substitute provides enhanced current handling (400 mA vs. 370 mA), superior DC resistance (290 mOhm vs. 1.39 Ohm), shielded construction, and extended temperature range (-55°C to 125°C), making it suitable for applications requiring higher performance margins.

Parameter Comparison

Engineering Selection Recommendations

Primary Application (AX97-10680): Select the AX97-10680 when the original design specifies unshielded construction, operates within the -40°C to 85°C temperature window, and current requirements are limited to 370 mA. This component is active in production with ROHS3 compliance and suitable for cost-optimized designs where shielding is not required.

Substitute Application (SRR6603-680ML): The SRR6603-680ML is selected when enhanced performance is required, including higher current capacity (400 mA), significantly lower DC resistance (290 mOhm), shielded construction for EMI mitigation, extended temperature operation (-55°C to 125°C), or when space constraints favor smaller package dimensions (6.60mm x 4.40mm vs. 7.30mm x 4.78mm). Both components maintain ROHS3 compliance and REACH unaffected status.

Compliance Considerations: Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for commercial and industrial applications. The substitute part offers MSL rating of 1 (Unlimited), indicating superior moisture handling characteristics compared to the main part.

Frequently Asked Questions (FAQ)

Q: Can the SRR6603-680ML directly replace the AX97-10680 in existing designs?

A: Yes, the SRR6603-680ML is a direct substitute based on matching inductance (68 µH), tolerance (±20%), core material (ferrite), core type (drum core wirewound), and mounting configuration (surface mount). The substitute provides superior electrical performance with higher current rating and lower DC resistance. Verify PCB footprint compatibility, as the substitute is physically smaller (6.60mm x 4.40mm vs. 7.30mm x 4.78mm).

Q: What is the primary difference between these two inductors?

A: The main differences are shielding configuration (unshielded vs. shielded), DC resistance (1.39 Ohm vs. 290 mOhm), current rating (370 mA vs. 400 mA), and operating temperature range (-40 to 85°C vs. -55 to 125°C). The SRR6603-680ML provides enhanced performance across all electrical parameters.

Q: Does the shielded construction of the SRR6603-680ML affect circuit performance?

A: Shielded construction reduces electromagnetic interference emission and susceptibility. In applications where EMI control is beneficial, the shielded substitute improves overall system performance. In applications where shielding is not required, both components function identically at the specified inductance value.

Q: Are there packaging differences between these parts?

A: Yes. The AX97-10680 is supplied in Box packaging, while the SRR6603-680ML is supplied in Tape & Reel (TR) format. Both are surface mount components suitable for automated assembly. Verify packaging requirements for your procurement and assembly processes.

Q: What is the significance of the lower DC resistance in the SRR6603-680ML?

A: Lower DC resistance (290 mOhm vs. 1.39 Ohm) reduces resistive losses in the inductor, resulting in lower heat generation and improved efficiency in power conversion applications. This is particularly beneficial in high-frequency switching circuits and current-limiting applications.

Q: Can I use the AX97-10680 in applications requiring the extended temperature range of the SRR6603-680ML?

A: No. The AX97-10680 is rated for -40°C to 85°C operation only. Applications requiring -55°C to 125°C operation must use the SRR6603-680ML or equivalent component rated for the extended range.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the AX97-10680 and SRR6603-680ML are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for commercial and industrial electronic components.
