AX97-101R5 Equivalent & Substitute Parts

Part Overview

The AX97-101R5 is a 1.5 µH unshielded drum core wirewound inductor manufactured by Triad Magnetics, rated for 2.8 A continuous current with a maximum DC resistance of 50 mOhm. This surface mount component operates across the temperature range of -40°C to 85°C and is ROHS3 compliant. The part is currently active in production with 945 units in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this inductor category. Substitution becomes necessary due to supply chain availability, lead time requirements, or inventory constraints while maintaining design integrity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX97-101R5 is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value must be 1.5 µH at 100 kHz test frequency
• Inductance tolerance must be ±20% or tighter
• Current rating must be 2.8 A or greater
• DC resistance must not exceed 50 mOhm maximum

Mechanical Compatibility Requirements:

• Core type must be drum core wirewound construction
• Core material must be ferrite
• Mounting type must be surface mount (SMD)
• Package classification must be nonstandard (consistent with AX97-101R5 form factor)

Compliance Requirements:

• ROHS3 compliance mandatory
• REACH unaffected status required

The substitute part SRR6603-1R5ML meets all electrical equivalence criteria with superior DC resistance performance (45 mOhm maximum versus 50 mOhm maximum) and extended operating temperature range. Mechanical compatibility is maintained through identical core construction and surface mount packaging. Both parts satisfy regulatory compliance requirements.

Engineering Selection Recommendations

Primary Selection: AX97-101R5

The AX97-101R5 remains the primary component choice when available. It is active in production with confirmed inventory of 945 units. The part meets all design requirements for 1.5 µH inductance at 2.8 A current rating with ROHS3 compliance and REACH unaffected status.

Substitute Selection: SRR6603-1R5ML

The SRR6603-1R5ML qualifies as a direct electrical and mechanical substitute. Selection of this substitute is appropriate when AX97-101R5 availability is constrained. The substitute provides equivalent inductance and current rating performance with improved DC resistance characteristics (45 mOhm maximum versus 50 mOhm maximum). Extended operating temperature range (-55°C to 125°C versus -40°C to 85°C) provides additional thermal margin for applications requiring lower temperature operation.

The SRR6603-1R5ML incorporates shielding, which reduces electromagnetic interference compared to the unshielded AX97-101R5. This characteristic may provide design benefits in noise-sensitive applications. Inventory availability is confirmed at 1018 units.

Packaging Consideration:

The AX97-101R5 is supplied in box packaging, while the SRR6603-1R5ML is supplied in tape and reel format. This difference affects handling, storage, and assembly line integration but does not impact electrical or mechanical performance.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component substitution.

Frequently Asked Questions (FAQ)

Q: Can the SRR6603-1R5ML replace the AX97-101R5 in all applications?

A: The SRR6603-1R5ML meets all critical electrical parameters (1.5 µH inductance, 2.8 A current rating, ±20% tolerance) and mechanical requirements (drum core wirewound, ferrite, surface mount). Both parts are ROHS3 compliant and REACH unaffected. Substitution is electrically and mechanically valid. The substitute offers improved DC resistance (45 mOhm versus 50 mOhm maximum) and extended temperature range (-55°C to 125°C versus -40°C to 85°C). Shielding differences should be evaluated for specific electromagnetic compatibility requirements.

Q: What are the key differences between these parts?

A: The primary differences are: (1) DC resistance—SRR6603-1R5ML is 45 mOhm maximum versus AX97-101R5 at 50 mOhm maximum; (2) Shielding—SRR6603-1R5ML is shielded while AX97-101R5 is unshielded; (3) Operating temperature range—SRR6603-1R5ML extends to -55°C to 125°C versus AX97-101R5 at -40°C to 85°C; (4) Packaging format—AX97-101R5 supplied in box, SRR6603-1R5ML in tape and reel.

Q: Are the physical dimensions compatible?

A: Physical dimensions differ slightly. AX97-101R5 measures 0.287" L × 0.188" W × 0.127" H (7.30mm × 4.78mm × 3.23mm). SRR6603-1R5ML measures 0.260" L × 0.173" W × 0.118" H (6.60mm × 4.40mm × 3.00mm). Both are nonstandard package form factors for surface mount applications. PCB layout and component placement should be verified for the smaller SRR6603-1R5ML footprint.

Q: Do both parts meet regulatory compliance requirements?

A: Both the AX97-101R5 and SRR6603-1R5ML are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification. Regulatory compliance is equivalent between the two parts.

Q: What is the significance of the shielding difference?

A: The AX97-101R5 is unshielded, while the SRR6603-1R5ML is shielded. Shielding reduces electromagnetic field radiation and susceptibility to external electromagnetic interference. In applications where EMI performance is critical, the shielded SRR6603-1R5ML may provide design advantages. In applications where shielding is not required, the unshielded AX97-101R5 is functionally equivalent.

Q: Can packaging format affect component selection?

A: Packaging format (box versus tape and reel) affects supply chain logistics, storage, and assembly line integration but does not impact electrical or mechanical performance. Selection between formats depends on manufacturing process requirements and inventory management practices rather than component functionality.
