Substitute Part Grouping Explanation

Substitution eligibility for the AX97-30100 is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 10 µH (within ±20% tolerance specification)
• Core material: Ferrite drum core construction
• Mounting type: Surface mount
• Package classification: Nonstandard SMD form factor

Secondary Compatibility Factors:

• Current rating capability (minimum 2 A acceptable for reduced-current applications)
• DC resistance within acceptable operating limits
• Operating temperature range overlap
• RoHS and REACH compliance status

The substitute part SRR1005-100M meets the primary inductance, core material, and mounting requirements. However, differences exist in current rating, shielding configuration, and DC resistance that must be evaluated for specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

AX97-30100 Selection Criteria:

• Applications requiring 4.6 A continuous current capacity
• Circuits where unshielded inductor configuration is acceptable
• Lower DC resistance requirement (40 mOhm max) for reduced power dissipation
• Operating environments within -40°C to 85°C range
• Bulk packaging for prototype or low-volume production

SRR1005-100M Selection Criteria:

• Applications with current requirements up to 2 A
• Circuits benefiting from shielded inductor construction for EMI reduction
• Extended operating temperature range to 125°C
• Tape & Reel packaging for automated assembly processes
• Higher DC resistance tolerance acceptable (65 mOhm max)

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility. Selection between these parts depends on specific circuit current demands, thermal environment, and manufacturing process requirements rather than compliance considerations.

Frequently Asked Questions (FAQ)

Q: Can SRR1005-100M directly replace AX97-30100 in all applications?

A: Direct replacement is limited by current rating. The SRR1005-100M is rated for 2 A maximum, while the AX97-30100 supports 4.6 A. Substitution is valid only in circuits where operating current does not exceed 2 A.

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

A: The AX97-30100 is unshielded, while the SRR1005-100M is shielded. Shielding reduces electromagnetic interference emission and susceptibility. Circuit design determines whether shielding is required or beneficial.

Q: How do DC resistance differences affect circuit performance?

A: The AX97-30100 has 40 mOhm maximum DCR; the SRR1005-100M has 65 mOhm maximum. Higher DCR increases power dissipation and heat generation. In high-current applications, the lower DCR of the AX97-30100 is advantageous.

Q: Are packaging differences significant for substitution?

A: Yes. The AX97-30100 is supplied in Bulk packaging, while the SRR1005-100M uses Tape & Reel. Bulk packaging suits manual assembly and prototyping; Tape & Reel is optimized for automated pick-and-place manufacturing.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are ROHS3 compliant and REACH unaffected. Regulatory compatibility is equivalent between the two parts.

Q: What is the impact of operating temperature range differences?

A: The AX97-30100 operates to 85°C maximum; the SRR1005-100M extends to 125°C. For applications in elevated temperature environments, the SRR1005-100M provides additional thermal margin.
