Substitute Part Grouping Explanation

Substitution of the AX97-10150 is determined by strict equivalence in the following electrical and mechanical parameters:

Primary Equivalence Criteria:

• Inductance value: 15 µH
• Inductance tolerance: ±20%
• Current rating: 800 mA minimum
• Core type: Drum core, wirewound ferrite
• Mounting type: Surface mount
• Inductance test frequency: 100 kHz
• RoHS compliance: ROHS3 Compliant

Acceptable Variation Parameters:

• DC resistance: Substitute parts with lower DCR values are acceptable as they represent improved performance
• Shielding: Shielded variants are acceptable substitutes for unshielded designs in applications where electromagnetic isolation is beneficial or neutral
• Operating temperature range: Substitute parts with extended temperature ranges are acceptable
• Package dimensions: Minor dimensional variations within nonstandard SMD specifications are acceptable provided mounting compatibility is maintained

The SRR6603-150ML from Bourns Inc. meets all primary equivalence criteria and represents a direct functional substitute with enhanced DC resistance performance.

Engineering Selection Recommendations

AX97-10150 Selection Criteria: The AX97-10150 is the primary choice when unshielded inductor characteristics are required and operating temperatures remain within the -40°C to 85°C specification. This part is ROHS3 compliant and maintains active production status.

SRR6603-150ML Selection Criteria: The SRR6603-150ML serves as a direct substitute when the following conditions apply:

• Shielded inductor performance is acceptable or beneficial to the circuit design
• Extended operating temperature range (-55°C to 125°C) is required
• Lower DC resistance (90mOhm versus 300mOhm) provides improved efficiency and reduced power dissipation
• Tape & Reel packaging format is compatible with assembly processes
• ROHS3 compliance and active production status are maintained

Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Selection between these parts depends on specific application requirements regarding shielding, temperature range, and DC resistance performance.

Frequently Asked Questions (FAQ)

Q: Can the SRR6603-150ML replace the AX97-10150 in all applications?

A: The SRR6603-150ML is electrically and mechanically compatible as a substitute. The primary differences are shielding (shielded versus unshielded), DC resistance (90mOhm versus 300mOhm), and operating temperature range (-55°C to 125°C versus -40°C to 85°C). Applications requiring unshielded operation or operating exclusively within the narrower temperature range should evaluate these differences against circuit requirements.

Q: What is the impact of the lower DC resistance in the SRR6603-150ML?

A: The SRR6603-150ML exhibits 90mOhm maximum DC resistance compared to 300mOhm in the AX97-10150. Lower DC resistance reduces resistive losses and power dissipation during current flow, resulting in improved efficiency and reduced thermal generation. This represents enhanced performance in the substitute part.

Q: Are there packaging compatibility considerations?

A: The AX97-10150 is supplied in Bulk packaging, while the SRR6603-150ML is supplied in Tape & Reel (TR) format. Both are surface mount components with nonstandard package dimensions. Assembly process compatibility with TR packaging must be confirmed for automated placement equipment.

Q: Does the shielding difference affect circuit performance?

A: The SRR6603-150ML incorporates shielding, while the AX97-10150 is unshielded. Shielded inductors reduce electromagnetic radiation and susceptibility to external magnetic fields. In applications where electromagnetic isolation is neutral or beneficial, the shielded variant presents no compatibility issues. Applications specifically requiring unshielded operation should retain the AX97-10150.

Q: Are both parts RoHS compliant?

A: Both the AX97-10150 and SRR6603-150ML are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
