AX97-30150 Equivalent & Substitute Parts Reference

Part Overview

The AX97-30150 is a 15 µH unshielded drum core wirewound inductor manufactured by Triad Magnetics, rated for 3.7 A continuous current with a maximum DC resistance of 50mOhm. 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 736 units in stock.

Substitute parts are identified when equivalent electrical performance can be maintained within the specified inductance tolerance and core material specifications, while accounting for differences in current rating, shielding configuration, and thermal operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX97-30150 is determined by the following criteria:

Primary Matching Criteria:

• Inductance value: 15 µH (within ±20% tolerance specification)
• Core material: Ferrite drum core wirewound construction
• Mounting type: Surface mount
• Regulatory compliance: ROHS3 compliant

Secondary Considerations:

• Current rating must support the application requirement
• DC resistance affects thermal performance and power dissipation
• Operating temperature range must encompass the application environment
• Shielding configuration may differ based on EMI requirements

The SRR1005-150M from Bourns Inc. matches the primary electrical specification (15 µH inductance, ferrite drum core, surface mount) and regulatory compliance. However, this substitute exhibits reduced current rating (1.7 A versus 3.7 A) and increased DC resistance (85mOhm versus 50mOhm maximum), which must be evaluated against specific application requirements.

Engineering Selection Recommendations

AX97-30150 Selection Criteria:

• Applications requiring 3.7 A continuous current capacity
• Systems with thermal operating limits at 85°C maximum
• Designs prioritizing lower DC resistance (50mOhm) for reduced power dissipation
• Unshielded configuration acceptable for EMI environment
• Bulk packaging suitable for prototype or low-volume production

SRR1005-150M Selection Criteria:

• Applications with current requirements not exceeding 1.7 A
• Systems capable of operating to 125°C ambient temperature
• Designs where shielded configuration provides EMI containment benefits
• Tape & Reel packaging suitable for automated assembly processes
• Higher DC resistance (85mOhm) acceptable within thermal budget

Both parts maintain ROHS3 compliance and REACH unaffected status. Selection between these components depends on current rating requirements and thermal operating environment specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can SRR1005-150M replace AX97-30150 in all applications?

A: No. The SRR1005-150M has a maximum current rating of 1.7 A compared to 3.7 A for the AX97-30150. Substitution is only valid for applications where the actual operating current does not exceed 1.7 A. Exceeding this rating will cause saturation and performance degradation.

Q: What is the impact of increased DC resistance in the SRR1005-150M?

A: The SRR1005-150M exhibits 85mOhm maximum DC resistance versus 50mOhm for the AX97-30150. This 70% increase in resistance results in higher power dissipation (I²R losses). For a 1.7 A current, the SRR1005-150M dissipates approximately 0.245 W compared to 0.145 W for the AX97-30150 at equivalent current levels.

Q: Does shielding affect circuit performance?

A: Shielding configuration affects electromagnetic field containment. The SRR1005-150M shielded design reduces radiated EMI compared to the unshielded AX97-30150. Selection depends on whether the application environment requires EMI suppression or operates in a controlled electromagnetic environment.

Q: Are the physical dimensions compatible?

A: No. The AX97-30150 measures 0.530" L × 0.370" W × 0.232" H (13.46mm × 9.40mm × 5.90mm). The SRR1005-150M measures 0.500" L × 0.394" W × 0.205" H (12.70mm × 10.00mm × 5.20mm). PCB layout and component placement must be verified before substitution.

Q: What packaging differences exist?

A: The AX97-30150 is supplied in Bulk packaging, while the SRR1005-150M is supplied in Tape & Reel (TR) format. Bulk packaging is typical for prototype quantities, while Tape & Reel is standard for automated assembly production runs.

Q: Are both parts RoHS compliant?

A: Yes. Both the AX97-30150 and SRR1005-150M are ROHS3 compliant and REACH unaffected, meeting current environmental regulatory requirements for electronic component manufacturing and use.

Q: What is the temperature operating range difference?

A: The AX97-30150 operates from -40°C to 85°C, while the SRR1005-150M operates from -40°C to 125°C. The SRR1005-150M provides 40°C additional high-temperature margin, which may be beneficial for applications in elevated ambient environments or near heat sources.
