AIRD-02-1R0M Equivalent & Substitute Parts

Part Overview

The AIRD-02-1R0M 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 is designed for applications requiring low inductance values with high current capacity and minimal resistance losses.

The AIRD-02-1R0M is currently listed as obsolete. 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 component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AIRD-02-1R0M is determined by the following critical parameters:

• Inductance Value: Must be 1 µH (exact match required)
• Current Rating: Must support minimum 11.4 A continuous current
• DC Resistance: Must not exceed 3 mOhm maximum
• Core Material: Ferrite drum core construction
• Shielding Configuration: Unshielded
• Mounting Type: Through hole radial configuration
• Physical Package: Radial, vertical cylinder form factor with 0.827" (21.00 mm) diameter

The AIRD-02-1R0N qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Tolerance differences and extended operating temperature range do not affect functional substitutability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The AIRD-02-1R0N is the recommended substitute for the obsolete AIRD-02-1R0M. Both components are manufactured by Abracon LLC within the same AIRD-02 series and maintain identical electrical performance specifications for inductance, current rating, saturation current, and DC resistance.

The AIRD-02-1R0N offers the following advantages:

• Active product status ensures ongoing availability and supply chain support
• Extended operating temperature range (-40°C ~ 125°C versus -25°C ~ 85°C) provides broader environmental compatibility
• ROHS3 compliance and REACH unaffected status maintain regulatory alignment
• Identical physical package and mounting configuration enable direct board-level substitution without layout modifications

The tolerance specification difference (±30% versus ±20%) does not impact substitutability for applications where the original ±20% tolerance was acceptable, as the substitute maintains the same nominal inductance value and core material properties.

Frequently Asked Questions (FAQ)

Q: Can the AIRD-02-1R0N be used as a direct replacement for the AIRD-02-1R0M on existing PCBs?

A: Yes. Both components share identical physical dimensions (0.827" diameter, 21.00 mm), mounting type (through hole radial), and package configuration (vertical cylinder). No PCB layout modifications are required.

Q: What is the significance of the tolerance difference between ±20% and ±30%?

A: Tolerance specifications define the acceptable range of inductance variation from the nominal 1 µH value. The AIRD-02-1R0N's ±30% tolerance is wider than the original ±20%. Applications requiring tighter inductance control should evaluate circuit performance within the ±30% range.

Q: Are there any electrical performance differences between these parts?

A: No. Both components deliver identical current ratings (11.4 A), saturation current (108 A), and maximum DC resistance (3 mOhm). Electrical performance in circuit operation is equivalent.

Q: Why is the AIRD-02-1R0M listed as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions. The AIRD-02-1R0N remains in active production and provides equivalent functionality.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the AIRD-02-1R0M and AIRD-02-1R0N are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings.

Q: What is the operating temperature consideration for substitution?

A: The AIRD-02-1R0N supports an extended temperature range (-40°C ~ 125°C) compared to the original part (-25°C ~ 85°C). This provides additional operational margin for applications exposed to wider environmental conditions.
