Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX97-30102 is determined by the following criteria:

Primary Electrical Parameters:

• Inductance value must equal 1 mH
• DC resistance must not exceed 3.15 Ohm maximum
• Current rating must support the application requirement

Mechanical Compatibility:

• Surface mount package configuration
• Drum core ferrite construction
• Physical dimensions compatible with PCB layout constraints

Environmental & Compliance:

• Operating temperature range must encompass or exceed -40°C to 85°C
• ROHS3 compliance required
• REACH unaffected status

The substitute part SRR1005-102K meets the primary electrical parameters with equivalent 1 mH inductance and 3.2 Ohm maximum DC resistance. However, the substitute exhibits a lower current rating of 220 mA compared to the main part's 300 mA specification, which restricts its application to circuits where the maximum continuous current does not exceed 220 mA.

Parameter Comparison

Engineering Selection Recommendations

AX97-30102 Selection Criteria:

• Applications requiring continuous current up to 300 mA
• Unshielded inductor configuration acceptable for circuit layout
• Operating temperature range limited to -40°C to 85°C
• ±20% inductance tolerance acceptable
• ROHS3 and REACH compliance required

SRR1005-102K Selection Criteria:

• Applications with maximum continuous current of 220 mA or less
• Shielded inductor configuration required to minimize electromagnetic interference
• Extended operating temperature range to 125°C required
• Tighter ±10% inductance tolerance required
• ROHS3 and REACH compliance required
• Packaging in Tape & Reel format for automated assembly

Both parts maintain ROHS3 compliance and REACH unaffected status. The substitute part provides superior inductance tolerance and extended temperature rating. Selection between these parts depends on the specific current requirement and whether shielding is necessary for the application circuit.

Frequently Asked Questions (FAQ)

Q: Can SRR1005-102K replace AX97-30102 in all applications?

A: No. The SRR1005-102K has a maximum current rating of 220 mA, which is 80 mA lower than the AX97-30102's 300 mA rating. Substitution is only valid for applications where the continuous current does not exceed 220 mA.

Q: What is the difference between shielded and unshielded inductors?

A: The AX97-30102 is unshielded, while the SRR1005-102K is shielded. Shielding reduces electromagnetic field radiation and susceptibility to external interference. Selection depends on circuit layout and EMI requirements.

Q: Are the physical dimensions compatible?

A: The AX97-30102 measures 0.530" L x 0.370" W x 0.232" H (13.46mm x 9.40mm x 5.90mm). The SRR1005-102K measures 0.500" L x 0.394" W x 0.205" H (12.70mm x 10.00mm x 5.20mm). Both are surface mount components with similar footprints, but PCB layout verification is required.

Q: What is the significance of inductance tolerance?

A: The AX97-30102 has ±20% tolerance, while the SRR1005-102K has ±10% tolerance. Tighter tolerance means more precise inductance values. Applications requiring strict inductance specifications should use the SRR1005-102K.

Q: Do both parts meet regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What packaging formats are available?

A: The AX97-30102 is supplied in Bulk packaging. The SRR1005-102K is supplied in Tape & Reel (TR) format, which is standard for automated PCB assembly processes.
