AIRD-02-1R0K Equivalent & Substitute Parts

Part Overview

The AIRD-02-1R0K is a 1 µH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 11.4 A continuous current with a maximum DC resistance of 3 mOhm. This through-hole radial component operates across the temperature range of -25°C to 85°C and is compliant with RoHS3 and REACH standards.

The AIRD-02-1R0K has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this inductor specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AIRD-02-1R0K is determined by the following critical parameters:

• Inductance Value: Must be 1 µH
• Current Rating: Must be 11.4 A minimum
• DC Resistance: Must not exceed 3 mOhm
• Saturation Current: Must be 108 A minimum
• Core Material: Must be Ferrite
• Shielding Configuration: Must be Unshielded
• Mounting Type: Must be Through Hole
• Package / Case: Must be Radial, Vertical Cylinder
• Physical Dimensions: Must match 0.827" Dia (21.00 mm)

The AIRD-02-1R0N qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is product status transition from obsolete to active, along with expanded operating temperature range and inductance tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

The AIRD-02-1R0N is the manufacturer-recommended substitute for the obsolete AIRD-02-1R0K. Both components maintain identical electrical performance specifications for inductance, current rating, saturation current, and DC resistance. Both are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment.

The AIRD-02-1R0N offers extended operating temperature range (-40°C to 125°C versus -25°C to 85°C), providing greater thermal margin for applications requiring operation at temperature extremes. The inductance tolerance specification differs (±30% versus ±10%), which should be evaluated against circuit design requirements for inductance accuracy.

Active product status of the AIRD-02-1R0N ensures ongoing manufacturer support, availability, and supply chain continuity compared to the obsolete AIRD-02-1R0K.

Frequently Asked Questions (FAQ)

Q: Can the AIRD-02-1R0N directly replace the AIRD-02-1R0K in existing designs?

A: Yes. Both components share identical inductance value (1 µH), current rating (11.4 A), saturation current (108 A), DC resistance (3 mOhm max), core material (ferrite), shielding configuration (unshielded), mounting type (through hole), and physical dimensions (0.827" diameter, 21.00 mm). Electrical and mechanical compatibility is confirmed.

Q: What is the significance of the inductance tolerance difference?

A: The AIRD-02-1R0K specifies ±10% inductance tolerance, while the AIRD-02-1R0N specifies ±30%. Applications requiring tighter inductance accuracy should evaluate whether the broader tolerance of the substitute part meets circuit performance requirements. For most general-purpose applications, the ±30% tolerance remains within acceptable operating margins.

Q: Does the extended operating temperature range of the AIRD-02-1R0N affect compatibility?

A: No. The AIRD-02-1R0N operating range (-40°C to 125°C) encompasses the original AIRD-02-1R0K range (-25°C to 85°C). The substitute part provides equal or superior thermal performance for all applications within the original temperature specification.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the AIRD-02-1R0K and AIRD-02-1R0N are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: Why is the AIRD-02-1R0K listed as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. The AIRD-02-1R0N represents the active continuation within the same AIRD-02 series, providing equivalent functionality with current manufacturing support.
