Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX97-20100 is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value: 10 µH (within ±20% tolerance band)
• Current rating: minimum 2 A continuous
• DC resistance: maximum 70 mOhm
• Core material: Ferrite drum core wirewound construction

Mechanical Compatibility Requirements:

• Mounting type: Surface mount
• Package classification: Nonstandard SMD form factor
• Physical dimensions: compatible with 0.530" L x 0.370" W footprint envelope

Compliance Requirements:

• ROHS3 compliance mandatory
• REACH unaffected status

The SRR1005-100M from Bourns Inc. meets all electrical equivalence criteria with superior DC resistance (65 mOhm maximum) and enhanced current saturation rating (3 A). Mechanical compatibility is maintained within the nonstandard SMD package class. Both parts carry identical ROHS3 and REACH compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the AX97-20100 and SRR1005-100M are active production components with full ROHS3 compliance and REACH unaffected status, qualifying them for use in regulated applications.

The AX97-20100 operates within a -40°C to 85°C temperature envelope and is available in higher stock quantity (1132 pieces). Selection of this part is appropriate for applications where the specified temperature range is sufficient and unshielded inductor operation is acceptable.

The SRR1005-100M operates across an extended temperature range (-40°C to 125°C) with lower maximum DC resistance (65 mOhm versus 70 mOhm) and specified saturation current of 3 A. The shielded construction provides electromagnetic containment. Selection of this part is appropriate for applications requiring extended thermal operation, lower resistive losses, or electromagnetic isolation. Packaging is supplied in tape and reel format with MSL rating of 1 (unlimited moisture sensitivity).

Frequently Asked Questions (FAQ)

Q: Can the SRR1005-100M directly replace the AX97-20100 in existing designs?

A: Electrical substitution is valid based on matching inductance (10 µH), current rating (2 A), and DC resistance specifications (65 mOhm maximum is within the 70 mOhm requirement). Mechanical compatibility exists within the nonstandard SMD package class. Physical dimensions differ slightly (SRR1005-100M: 0.500" L x 0.394" W versus AX97-20100: 0.530" L x 0.370" W), requiring PCB layout verification. The shielded construction of the SRR1005-100M may alter electromagnetic coupling characteristics in the circuit.

Q: What is the significance of the shielding difference?

A: The AX97-20100 is unshielded, while the SRR1005-100M is shielded. Shielding reduces electromagnetic radiation and susceptibility to external fields. Circuit design must account for this difference, particularly in noise-sensitive applications or high-density PCB layouts.

Q: Are both parts suitable for high-temperature applications?

A: The AX97-20100 operates to 85°C maximum. The SRR1005-100M extends to 125°C. Selection depends on the application's thermal requirements. For applications exceeding 85°C ambient or junction temperature, the SRR1005-100M is the appropriate choice.

Q: What packaging formats are available?

A: The AX97-20100 is supplied in box packaging. The SRR1005-100M is supplied in tape and reel format. Procurement and assembly processes must accommodate these different packaging specifications.

Q: Do both parts meet regulatory compliance requirements?

A: Both parts are ROHS3 compliant and REACH unaffected, qualifying them for use in regulated markets and applications with environmental compliance requirements.
