Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX97-30470 is determined by the following criteria:

Primary Matching Parameters:

• Inductance value: 47 µH (exact match required)
• Core type: Ferrite drum core wirewound construction
• Mounting: Surface mount technology
• Compliance: ROHS3 and REACH standards

Acceptable Variation Parameters:

• Current rating: Substitute must support minimum 2 A or higher
• DC resistance: Substitute DCR must not exceed application thermal limits
• Tolerance: ±15% to ±20% acceptable
• Shielding: Both shielded and unshielded configurations acceptable based on EMI requirements
• Operating temperature: Substitute range must encompass or exceed -40°C to 85°C

The SRR1005-470Y from Bourns Inc. meets the primary matching criteria with equivalent 47 µH inductance and ferrite drum core construction. Differences in current rating, DC resistance, and shielding are documented for engineering evaluation.

Parameter Comparison

Engineering Selection Recommendations

AX97-30470 (Primary Selection):

• Use when 2 A current rating is required
• Suitable for applications where unshielded construction is acceptable
• ROHS3 and REACH compliant for regulated markets
• Active product status ensures continued availability

SRR1005-470Y (Substitute Selection):

• Use when shielded construction is required for EMI mitigation
• Suitable for applications with current requirements up to 1 A
• Extended operating temperature range (-40 to 125°C) supports wider thermal environments
• ROHS3 and REACH compliant
• Active product status with higher inventory availability (2408 pieces)
• Tighter inductance tolerance (±15%) provides improved precision

Selection between these parts depends on specific application current requirements and electromagnetic shielding needs. Both parts maintain regulatory compliance and active production status.

Frequently Asked Questions (FAQ)

Q: Can SRR1005-470Y replace AX97-30470 in all applications?

A: No. The SRR1005-470Y has a maximum current rating of 1 A, while the AX97-30470 is rated for 2 A. Substitution is valid only when application current requirements do not exceed 1 A. Exceeding this rating will cause inductor saturation and performance degradation.

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

A: Shielded inductors (SRR1005-470Y) contain electromagnetic shielding to reduce radiated EMI and susceptibility to external magnetic fields. Unshielded inductors (AX97-30470) have no shielding. Selection depends on circuit layout and EMI requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both AX97-30470 and SRR1005-470Y are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for restricted substances.

Q: What is the significance of DC resistance differences?

A: The AX97-30470 has 160 mOhm maximum DCR while SRR1005-470Y has 190 mOhm maximum. Higher DCR increases resistive losses and heat generation. Selection should account for thermal budget and efficiency requirements.

Q: Do these inductors have different package dimensions?

A: Yes. AX97-30470 measures 0.530" L × 0.370" W × 0.232" H (13.46mm × 9.40mm × 5.90mm). SRR1005-470Y measures 0.500" L × 0.394" W × 0.205" H (12.70mm × 10.00mm × 5.20mm). PCB layout and clearance requirements must be verified before substitution.

Q: Which part has better inductance tolerance?

A: SRR1005-470Y offers ±15% tolerance compared to AX97-30470's ±20%. Tighter tolerance provides improved circuit performance consistency and reduced design margin requirements.
