Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX97-10470 is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 47 µH (within ±20% tolerance specification)
• Core type: Drum core wirewound construction
• Core material: Ferrite
• Mounting type: Surface mount
• Test frequency: 100 kHz

Secondary Compatibility Factors:

• Current rating must equal or exceed 460 mA
• DC resistance must not exceed 920mOhm maximum
• Operating temperature range must encompass or exceed -40°C to 85°C
• RoHS3 compliance required

The substitute part SRR6603-470ML from Bourns Inc. meets all primary matching criteria and demonstrates superior performance in secondary factors, including higher current rating (500 mA), lower DC resistance (230mOhm), and extended temperature range (-55°C to 125°C).

Parameter Comparison

Engineering Selection Recommendations

AX97-10470 Selection Criteria:

• Primary sourcing option when unshielded inductor configuration is required
• Suitable for applications with temperature operating range limited to -40°C to 85°C
• Appropriate when DC resistance specification of 920mOhm maximum is acceptable
• ROHS3 compliance and EAR99 export classification confirmed

SRR6603-470ML Selection Criteria:

• Substitute option when shielded inductor construction is beneficial for EMI reduction
• Applicable for extended temperature range applications (-55°C to 125°C)
• Preferred when lower DC resistance (230mOhm) reduces thermal dissipation requirements
• Higher current rating (500 mA) provides additional design margin
• ROHS3 compliance and EAR99 export classification confirmed
• Packaging available in Tape & Reel format with MSL 1 rating

Both parts maintain active production status and are REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can SRR6603-470ML directly replace AX97-10470 in existing designs?

A: SRR6603-470ML is electrically compatible as a substitute. Both components share identical inductance (47 µH), tolerance (±20%), core type (drum core wirewound ferrite), and mounting type (surface mount). The substitute provides superior performance with lower DC resistance and higher current rating. Physical dimensions differ slightly (SRR6603-470ML: 6.60mm × 4.40mm × 3.00mm vs. AX97-10470: 7.30mm × 4.78mm × 3.23mm), requiring PCB layout verification.

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

A: AX97-10470 is unshielded, while SRR6603-470ML is shielded. Shielding reduces electromagnetic interference (EMI) coupling to adjacent circuit elements. Selection depends on application EMI requirements and circuit layout constraints.

Q: Are there packaging differences that affect procurement?

A: AX97-10470 is supplied in Box packaging; SRR6603-470ML is supplied in Tape & Reel (TR) format. This affects handling, storage, and automated assembly compatibility. Tape & Reel packaging is standard for high-volume surface mount production.

Q: Do operating temperature ranges affect part selection?

A: AX97-10470 operates from -40°C to 85°C; SRR6603-470ML operates from -55°C to 125°C. For applications requiring extended temperature operation, SRR6603-470ML is the appropriate selection. For standard industrial temperature ranges, both parts are suitable.

Q: How do DC resistance specifications impact circuit performance?

A: AX97-10470 specifies 920mOhm maximum DC resistance; SRR6603-470ML specifies 230mOhm maximum. Lower DC resistance reduces I²R losses and thermal dissipation. For current-limited applications or thermal-sensitive designs, SRR6603-470ML provides superior performance.

Q: Are both parts RoHS3 compliant?

A: Yes. Both AX97-10470 and SRR6603-470ML are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for EU and global markets.
