AX97-10471 Equivalent & Substitute Parts Reference

Part Overview

The AX97-10471 is a 470 µH unshielded drum core wirewound inductor manufactured by Triad Magnetics, rated for 120 mA continuous current with a maximum DC resistance of 11.55 Ohm. This surface mount component operates across the temperature range of -40°C to 85°C and is specified at 100 kHz inductance frequency test conditions. The part is ROHS3 compliant and currently active in production. Substitute parts are identified when equivalent inductance values, current ratings, and core material specifications align within acceptable tolerance ranges, enabling direct functional replacement in circuit applications where the original part becomes unavailable or when alternative packaging or performance characteristics are required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX97-10471 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Inductance value: 470 µH (within ±20% tolerance specification)
• Core material: Ferrite drum core construction
• Mounting type: Surface mount configuration
• Regulatory compliance: ROHS3 compliant status

Secondary Compatibility Factors:

• Current rating: Substitute must support minimum 120 mA continuous current
• DC resistance: Lower DCR values indicate improved efficiency but do not preclude substitution
• Operating temperature range: Substitute must cover or exceed the -40°C to 85°C specification
• Package type: Surface mount nonstandard packages with compatible footprint dimensions

The SRR6603-471ML from Bourns Inc. qualifies as a substitute part because it maintains the 470 µH inductance specification, ferrite drum core construction, surface mount configuration, and ROHS3 compliance. While the substitute exhibits superior electrical characteristics (190 mA current rating, 1.8 Ohm DCR, shielded construction), these enhancements do not prevent functional replacement in applications designed for the AX97-10471.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The SRR6603-471ML is functionally equivalent to the AX97-10471 for applications requiring 470 µH inductance at surface mount configuration. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

Performance Considerations:

The substitute part demonstrates superior electrical characteristics across multiple parameters. The reduced DC resistance (1.8 Ohm versus 11.55 Ohm) results in lower power dissipation and improved efficiency in current-carrying applications. The higher current rating (190 mA versus 120 mA) provides additional design margin. The extended operating temperature range (-55°C to 125°C versus -40°C to 85°C) accommodates broader environmental specifications. The shielded construction of the substitute reduces electromagnetic interference coupling compared to the unshielded main part.

Physical Integration:

The substitute part exhibits a smaller footprint (6.60mm x 4.40mm versus 7.30mm x 4.78mm) and lower profile (3.00mm versus 3.23mm), enabling integration into space-constrained layouts. Verification of PCB land pattern compatibility is necessary prior to implementation.

Packaging Considerations:

The main part is supplied in bulk packaging, while the substitute is supplied in tape and reel format. Procurement and assembly processes must accommodate this packaging difference.

Frequently Asked Questions (FAQ)

Q: Can the SRR6603-471ML directly replace the AX97-10471 in existing circuit designs?

A: Yes, the SRR6603-471ML provides functional equivalence for the AX97-10471 based on matching inductance value (470 µH), core material (ferrite), and mounting type (surface mount). The substitute's superior electrical characteristics (lower DCR, higher current rating) and shielded construction do not prevent direct replacement. Physical footprint verification is required to confirm PCB compatibility.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) DC resistance is significantly lower in the substitute (1.8 Ohm versus 11.55 Ohm), reducing power loss; (2) current rating is higher (190 mA versus 120 mA), providing additional design margin; (3) the substitute includes shielding while the main part is unshielded; (4) operating temperature range is wider (-55°C to 125°C versus -40°C to 85°C); (5) physical dimensions are slightly smaller; (6) packaging format differs (tape & reel versus bulk).

Q: Are both parts compliant with regulatory requirements?

A: Yes, both the AX97-10471 and SRR6603-471ML are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: Does the shielded construction of the substitute affect circuit performance?

A: The shielded construction of the SRR6603-471ML reduces electromagnetic interference coupling to surrounding circuit elements compared to the unshielded AX97-10471. This characteristic is generally beneficial in noise-sensitive applications and does not negatively impact circuit function.

Q: What considerations apply to PCB layout when substituting these parts?

A: The substitute part has a smaller footprint (6.60mm x 4.40mm versus 7.30mm x 4.78mm) and lower profile (3.00mm versus 3.23mm). Existing PCB land patterns designed for the AX97-10471 must be verified for compatibility with the SRR6603-471ML dimensions. Minor layout adjustments may be necessary to accommodate the smaller component size.

Q: How do the inductance tolerances compare?

A: Both parts specify ±20% inductance tolerance at 100 kHz test frequency, ensuring equivalent tolerance performance in circuit applications.
