Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX97-10100 is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 10 µH (within ±20% tolerance specification)
• Current rating: 1 A minimum
• Core material: Ferrite drum core, wirewound construction
• Mounting type: Surface mount
• Inductance test frequency: 100 kHz

Secondary Compatibility Factors:

• DC resistance must not exceed application circuit requirements
• Operating temperature range must encompass the intended use environment
• RoHS3 compliance status
• Physical dimensions must fit the PCB layout constraints

The SRR6603-100ML from Bourns Inc. meets all primary matching criteria and qualifies as a direct substitute based on identical inductance value, current rating, core material, and mounting configuration.

Engineering Selection Recommendations

AX97-10100 Selection Criteria:

• Primary choice when unshielded inductor configuration is required by circuit design
• Suitable for applications where electromagnetic interference emission is not a design constraint
• Appropriate when operating temperature range of -40°C to 85°C satisfies system requirements
• Preferred when cut tape packaging format aligns with assembly process specifications

SRR6603-100ML Selection Criteria:

• Substitute when shielded inductor construction is required to minimize EMI coupling to adjacent circuit elements
• Applicable in designs requiring extended operating temperature range (-55°C to 125°C)
• Advantageous when lower DC resistance (75mOhm vs. 220mOhm) reduces power dissipation in the inductor
• Suitable when tape & reel packaging format is compatible with automated assembly equipment
• Both parts maintain ROHS3 compliance and REACH unaffected status

Physical dimensions differ slightly between parts. PCB layout verification is necessary to confirm fit within allocated component space.

Frequently Asked Questions (FAQ)

Q: Can SRR6603-100ML directly replace AX97-10100 in all applications?

A: Both parts share identical inductance value (10 µH), tolerance (±20%), current rating (1 A), core material (ferrite), and mounting type (surface mount). The primary difference is shielding configuration. SRR6603-100ML includes shielding while AX97-10100 is unshielded. Substitution is valid when the circuit design permits or requires a shielded inductor. Physical dimensions differ slightly; PCB layout must be verified.

Q: What is the significance of the DC resistance difference between these parts?

A: AX97-10100 has a maximum DC resistance of 220mOhm, while SRR6603-100ML is specified at 75mOhm maximum. Lower DC resistance reduces resistive power loss in the inductor. Selection depends on application power budget requirements. Both values are within acceptable ranges for 1 A rated inductors.

Q: Does the shielding difference affect circuit performance?

A: Shielding reduces electromagnetic field radiation from the inductor and provides immunity to external magnetic field interference. AX97-10100 (unshielded) is suitable for applications where EMI is not a concern. SRR6603-100ML (shielded) is preferred in noise-sensitive circuits or high-density PCB layouts where multiple inductors operate in proximity.

Q: Are the operating temperature ranges compatible?

A: AX97-10100 operates from -40°C to 85°C. SRR6603-100ML operates from -55°C to 125°C. If the application requires operation below -40°C or above 85°C, SRR6603-100ML is the only suitable option. For applications within -40°C to 85°C, both parts are compatible.

Q: What packaging format differences exist?

A: AX97-10100 is supplied in cut tape (CT) format. SRR6603-100ML is supplied in tape & reel (TR) format. Cut tape is suitable for manual assembly or small-volume production. Tape & reel format is optimized for high-speed automated assembly equipment. Selection depends on manufacturing process requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both AX97-10100 and SRR6603-100ML are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
