Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX97-106R8 is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value must be 6.8 µH within the ±20% tolerance band
• Current rating must meet or exceed 1.3 A
• DC resistance must not exceed 170mOhm maximum
• Inductance test frequency must be 100 kHz

Mechanical Compatibility Criteria:

• Mounting type must be surface mount
• Package classification must be nonstandard SMD format
• Physical dimensions must be compatible with the PCB footprint

Compliance Criteria:

• RoHS3 compliance required
• REACH unaffected status required
• Active product status required

The substitute part SRR6603-6R8ML from Bourns Inc. meets the electrical equivalence criteria with matching inductance value and test frequency. However, design differences exist in current rating, DC resistance, shielding configuration, and physical dimensions that must be evaluated for specific application requirements.

Engineering Selection Recommendations

AX97-106R8 Selection Criteria:

• Primary choice when unshielded inductor configuration is required
• Suitable for applications operating within -40°C to 85°C temperature range
• Appropriate when current demand is at or near 1.3 A maximum rating
• Box packaging format for manual assembly or small-volume production

SRR6603-6R8ML Selection Criteria:

• Applicable when shielded inductor configuration is required to reduce electromagnetic interference
• Suitable for applications requiring extended temperature operation up to 125°C
• Current rating of 1.2 A is acceptable only when application current demand does not exceed this value
• Lower DC resistance of 65mOhm provides reduced power dissipation compared to 170mOhm maximum
• Tape & Reel packaging format for automated assembly processes
• Smaller physical footprint (6.60mm x 4.40mm vs 7.30mm x 4.78mm) may provide PCB layout advantages

Both parts maintain ROHS3 compliance and active product status. Selection between these parts depends on specific application requirements for shielding, temperature range, current capacity, and packaging format.

Frequently Asked Questions (FAQ)

Q: Can SRR6603-6R8ML be used as a direct replacement for AX97-106R8?

A: Direct replacement is not guaranteed. While both parts share the same 6.8 µH inductance value and ±20% tolerance, the SRR6603-6R8ML has a lower current rating (1.2 A vs 1.3 A) and different shielding configuration (shielded vs unshielded). Application circuit requirements must be evaluated to confirm compatibility.

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

A: The AX97-106R8 is unshielded, while the SRR6603-6R8ML is shielded. Shielded inductors reduce electromagnetic field radiation and susceptibility to external interference. Selection depends on whether the application circuit requires EMI mitigation.

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

A: The SRR6603-6R8ML has significantly lower DC resistance (65mOhm max vs 170mOhm max). Lower resistance reduces I²R power dissipation and heat generation. This difference is material in high-current or thermally constrained applications.

Q: Are the physical dimensions compatible with the same PCB footprint?

A: No. The AX97-106R8 measures 7.30mm x 4.78mm x 3.23mm (max height), while the SRR6603-6R8ML measures 6.60mm x 4.40mm x 3.00mm (max height). PCB layout verification is required before substitution.

Q: What packaging format differences exist between these parts?

A: The AX97-106R8 is supplied in Box packaging, suitable for manual assembly. The SRR6603-6R8ML is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the AX97-106R8 and SRR6603-6R8ML are ROHS3 compliant and REACH unaffected. Both maintain active product status with established supply chains.

Q: What is the temperature operating range difference?

A: The AX97-106R8 operates from -40°C to 85°C, while the SRR6603-6R8ML operates from -55°C to 125°C. The Bourns part supports extended temperature range operation, which may be required in automotive or industrial applications.
