Substitute Part Grouping Explanation

Substitution eligibility for the AX1005-102K is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

Inductance value: 1 mH (±10% tolerance)
Current rating: minimum 220 mA
DC resistance: maximum 3.2 Ohm
Core material: Ferrite
Shielding: Shielded configuration

Mechanical Compatibility Requirements:

Mounting type: Surface Mount
Physical footprint: 12.70mm L x 10.00mm W (nonstandard package)
Height compatibility: within acceptable PCB assembly constraints

Compliance Requirements:

RoHS3 compliance
REACH unaffected status
Active product status

The SRR1005-102K manufactured by Bourns Inc. meets all electrical and mechanical equivalence criteria, with identical inductance, current rating, DC resistance, core material, and shielding specifications. Physical dimensions are identical. Both components maintain RoHS3 and REACH compliance.

Engineering Selection Recommendations

Primary Selection (AX1005-102K): The AX1005-102K remains the primary component choice when available. It is manufactured by Triad Magnetics, carries Active product status, and meets all RoHS3 and REACH compliance requirements. Current inventory of 1057 pieces supports immediate procurement.

Substitute Selection (SRR1005-102K): The SRR1005-102K manufactured by Bourns Inc. is a direct electrical and mechanical equivalent. All critical parameters—inductance, current rating, DC resistance, core material, and shielding—are identical. Physical footprint compatibility is confirmed. The substitute component offers an extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C), providing additional thermal margin for applications operating at elevated temperatures. Both components maintain identical RoHS3 and REACH compliance status. Packaging differs (Bulk for AX1005-102K versus Tape & Reel for SRR1005-102K), with SRR1005-102K offering higher inventory availability (15100 pieces).

Selection Criteria:

Use AX1005-102K when Triad Magnetics supply is available and Bulk packaging is required
Use SRR1005-102K when extended temperature operation is required or Tape & Reel packaging is preferred
Both components are suitable for identical circuit applications within the specified parameter ranges

Frequently Asked Questions (FAQ)

Q: Can SRR1005-102K replace AX1005-102K in all applications?

A: Yes. The SRR1005-102K meets all electrical equivalence criteria: identical 1 mH inductance, 220 mA current rating, 3.2 Ohm maximum DC resistance, ferrite core material, and shielded configuration. Physical dimensions are identical (12.70mm x 10.00mm). Both components are RoHS3 compliant and REACH unaffected. The substitute component is suitable for direct replacement in circuit designs.

Q: What is the difference in height between these components?

A: The AX1005-102K has a maximum seated height of 4.90mm, while the SRR1005-102K has a maximum seated height of 5.20mm. This 0.30mm difference is within typical PCB assembly tolerances and does not affect functional compatibility. Verify clearance in applications with height-constrained layouts.

Q: Are there temperature rating differences?

A: Yes. The AX1005-102K operates from -40°C to 85°C, while the SRR1005-102K operates from -40°C to 125°C. The SRR1005-102K provides extended high-temperature capability. For applications operating above 85°C, the SRR1005-102K is the appropriate selection.

Q: What packaging formats are available?

A: The AX1005-102K is supplied in Bulk packaging. The SRR1005-102K is supplied in Tape & Reel (TR) format. Select based on assembly process requirements and inventory management practices.

Q: Are both components compliant with current regulations?

A: Yes. Both the AX1005-102K and SRR1005-102K are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the saturation current specification?

A: The AX1005-102K does not specify saturation current (listed as "-"). The SRR1005-102K specifies saturation current (Isat) at 320 mA, which exceeds the 220 mA rated current, confirming adequate saturation margin for the specified operating range.
