AX97-30101 Equivalent & Substitute Parts Reference

Part Overview

The AX97-30101 is a 100 µH unshielded drum core wirewound inductor manufactured by Triad Magnetics, rated for 1.5 A continuous current with a maximum DC resistance of 300mOhm. This surface mount component operates across the temperature range of -40°C to 85°C and is ROHS3 compliant. The part is currently active in production with 929 pieces available in stock.

Substitute parts are identified when equivalent inductance values, compatible current ratings, and matching core materials are available from alternative manufacturers. Substitution becomes necessary due to supply chain considerations, packaging preferences, or specific application requirements while maintaining electrical performance within acceptable parameters.

Substitute Part Grouping Explanation

Substitute parts for the AX97-30101 are identified based on the following electrical and mechanical criteria:

Primary Matching Criteria:

• Inductance value: 100 µH (exact match required)
• Core material: Ferrite drum core wirewound construction
• Mounting type: Surface mount
• Current rating: Minimum 680 mA (acceptable for applications requiring up to 1.5 A with thermal derating considerations)
• DC resistance: Maximum 420mOhm (within acceptable operating parameters)
• Compliance: ROHS3 compliant

Substitution Logic: The SRR1005-101K from Bourns Inc. matches the primary inductance specification and core construction. While the current rating of 680 mA is lower than the main part's 1.5 A rating, this substitute is applicable in circuits where the actual operating current does not exceed the substitute's saturation current of 900 mA. The shielded construction of the substitute provides additional electromagnetic isolation compared to the unshielded main part, making it suitable for noise-sensitive applications.

Engineering Selection Recommendations

AX97-30101 Selection Criteria: Select the AX97-30101 when the application requires an unshielded inductor with a continuous current rating of 1.5 A and maximum DC resistance of 300mOhm. This part is suitable for general-purpose filtering and energy storage applications where electromagnetic shielding is not a design requirement. The part is ROHS3 compliant and operates within the -40°C to 85°C temperature range.

SRR1005-101K Selection Criteria: Select the SRR1005-101K when the application operates at currents not exceeding 680 mA continuous or 900 mA saturation current, and when shielded construction is beneficial for noise immunity. This substitute offers tighter inductance tolerance (±10% versus ±20%), extended operating temperature range (-40°C to 125°C), and lower profile height (5.20mm versus 5.90mm). The SRR1005-101K is ROHS3 compliant and available in tape and reel packaging for automated assembly.

Both parts are active products with current manufacturing status and full compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the SRR1005-101K replace the AX97-30101 in all applications?

A: The SRR1005-101K is a suitable substitute only when the circuit operating current does not exceed 680 mA continuous. Applications requiring the full 1.5 A rating of the AX97-30101 must use the original part or verify that the substitute's saturation current of 900 mA is sufficient for the specific application.

Q: What is the difference between shielded and unshielded construction?

A: The AX97-30101 is unshielded, while the SRR1005-101K is shielded. Shielded construction reduces electromagnetic radiation and susceptibility to external interference. Selection depends on whether the application requires this additional isolation.

Q: Are there packaging differences between these parts?

A: Yes. The AX97-30101 is supplied in bulk packaging, while the SRR1005-101K is supplied in tape and reel (TR) format. Tape and reel packaging is optimized for automated pick-and-place assembly, while bulk packaging is suitable for manual assembly or lower-volume applications.

Q: How do the inductance tolerances compare?

A: The AX97-30101 has a tolerance of ±20%, while the SRR1005-101K has a tighter tolerance of ±10%. Applications requiring closer inductance accuracy should specify the SRR1005-101K.

Q: What is the operating temperature difference?

A: The AX97-30101 operates from -40°C to 85°C, while the SRR1005-101K operates from -40°C to 125°C. The SRR1005-101K is suitable for higher-temperature environments.

Q: Are both parts RoHS compliant?

A: Yes, both the AX97-30101 and SRR1005-101K are ROHS3 compliant and REACH unaffected.
