AX97-30151 Equivalent & Substitute Parts Reference

Part Overview

The AX97-30151 is a 150 µH fixed unshielded drum core wirewound inductor manufactured by Triad Magnetics, rated for 1.2 A continuous current with a maximum DC resistance of 440mOhm. 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 1047 units in stock.

Substitute parts are identified when equivalent inductance values, compatible current ratings, acceptable DC resistance specifications, and matching mounting technologies are available from alternative manufacturers. Substitution becomes necessary due to supply constraints, lead time requirements, or packaging format availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX97-30151 is determined by the following criteria:

Primary Matching Parameters:

• Inductance value: 150 µH (exact match required)
• Core type: Drum core wirewound construction
• Core material: Ferrite
• Mounting technology: Surface mount
• RoHS compliance: ROHS3 Compliant

Secondary Compatibility Parameters:

• Current rating: Substitute must support minimum 550 mA (lower than main part's 1.2 A is acceptable only if application requirements permit)
• DC resistance: Substitute maximum DCR must not exceed 520mOhm (within acceptable tolerance for equivalent performance)
• Operating temperature: Substitute range must encompass or exceed -40°C to 85°C
• REACH compliance: REACH Unaffected status required

The SRR1005-151K from Bourns Inc. meets all primary matching parameters and maintains ROHS3 and REACH compliance. The substitute exhibits lower current rating (550 mA vs. 1.2 A) and slightly higher DC resistance (520mOhm vs. 440mOhm), which represents a trade-off in electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (AX97-30151): Select the AX97-30151 when the application requires the full 1.2 A current rating and the lower DC resistance specification of 440mOhm maximum. This part is suitable for circuits where thermal dissipation and current handling capacity are critical design parameters. The unshielded configuration is appropriate for applications with minimal EMI coupling concerns.

Substitute Part Selection (SRR1005-151K): The SRR1005-151K from Bourns Inc. is suitable as a substitute when:

• Application current requirements do not exceed 550 mA
• The slightly elevated DC resistance of 520mOhm is acceptable within circuit design margins
• EMI shielding provides design advantage
• Extended operating temperature range to 125°C is beneficial
• Tape & Reel packaging format aligns with production assembly processes

Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for equivalent applications. The substitute offers tighter inductance tolerance (±10% vs. ±20%), which may improve circuit performance consistency.

Frequently Asked Questions (FAQ)

Q: Can the SRR1005-151K directly replace the AX97-30151 in all applications?

A: Direct replacement is possible only when the application current requirement does not exceed 550 mA. The AX97-30151 is rated for 1.2 A; the SRR1005-151K is rated for 550 mA. If the circuit draws current above 550 mA, the substitute will not provide equivalent performance and may experience thermal stress or saturation effects.

Q: What is the significance of the shielding difference between these parts?

A: The AX97-30151 is unshielded, while the SRR1005-151K is shielded. Shielding reduces electromagnetic interference coupling to adjacent circuit elements. In applications sensitive to EMI, the shielded substitute may provide improved performance. In applications where shielding is not required, both configurations are functionally equivalent for inductance delivery.

Q: How does the DC resistance difference affect circuit performance?

A: The SRR1005-151K exhibits 80 mOhm higher maximum DC resistance (520mOhm vs. 440mOhm). This increases resistive losses and heat dissipation in the inductor. For circuits operating at or near the 550 mA current limit, the additional resistance may produce measurable thermal effects. Circuit designers must verify that the higher DCR does not violate thermal or efficiency specifications.

Q: Are the packaging formats interchangeable?

A: No. The AX97-30151 is supplied in Bulk packaging, while the SRR1005-151K is supplied in Tape & Reel (TR) format. Bulk packaging requires manual handling during assembly, while Tape & Reel format is compatible with automated pick-and-place equipment. Packaging selection depends on production assembly capabilities and handling procedures.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the AX97-30151 and SRR1005-151K are ROHS3 compliant and REACH Unaffected. They satisfy equivalent regulatory requirements for use in compliant applications. No additional compliance verification is required when substituting between these parts.

Q: What is the inductance tolerance impact of substitution?

A: The AX97-30151 has ±20% inductance tolerance, while the SRR1005-151K has ±10% tolerance. The substitute provides tighter tolerance control, which may improve circuit performance consistency and reduce design margin requirements. This represents a performance advantage in applications where inductance precision is critical.
