AIRD-01-2R7M Equivalent & Substitute Parts

Part Overview

The AIRD-01-2R7M is a 2.7 µH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 9 A continuous current with a maximum DC resistance of 5 mOhm. This through-hole radial component operates across the temperature range of -25°C to 85°C and is compliant with RoHS3 standards.

The AIRD-01-2R7M has reached obsolete product status. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications requiring this inductance value and current rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AIRD-01-2R7M is determined by the following critical parameters:

• Inductance Value: Must be 2.7 µH
• Current Rating: Must support minimum 9 A continuous current
• DC Resistance: Must not exceed 5 mOhm maximum
• Core Material: Ferrite drum core construction
• Shielding Configuration: Unshielded
• Mounting Interface: Through-hole radial configuration
• Physical Envelope: Radial vertical cylinder package with compatible dimensions

The AIRD-01-2R7N meets all substitution criteria. Both parts share identical inductance, current rating, DCR specification, core material, shielding type, and mounting configuration. Physical dimensions remain compatible within the radial vertical cylinder package class.

Engineering Selection Recommendations

The AIRD-01-2R7N is the direct substitute for the obsolete AIRD-01-2R7M. Both components are manufactured by Abracon LLC within the same AIRD-01 series and maintain electrical and mechanical compatibility.

Key selection factors:

• Product Status: The AIRD-01-2R7N carries active product status with confirmed inventory availability (1108 pcs), whereas the AIRD-01-2R7M is obsolete with limited remaining stock (954 pcs).
• Compliance: Both parts maintain RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.
• Temperature Range: The AIRD-01-2R7N provides an extended operating temperature range (-40°C ~ 125°C) compared to the main part (-25°C ~ 85°C), offering broader thermal performance capability.
• Inductance Tolerance: The AIRD-01-2R7N specifies ±30% tolerance versus ±20% for the main part. Applications requiring tighter inductance tolerance must evaluate circuit performance impact.

Frequently Asked Questions (FAQ)

Q: Can the AIRD-01-2R7N directly replace the AIRD-01-2R7M in existing designs?

A: Yes. Both parts share identical inductance (2.7 µH), current rating (9 A), DC resistance (5 mOhm max), core material (ferrite), shielding configuration (unshielded), and through-hole radial mounting. Physical dimensions are compatible within the radial vertical cylinder package class.

Q: What is the difference in inductance tolerance between these parts?

A: The AIRD-01-2R7M specifies ±20% tolerance, while the AIRD-01-2R7N specifies ±30% tolerance. For applications with strict inductance requirements, circuit simulation or empirical testing may be necessary to confirm acceptable performance margins with the wider tolerance of the substitute part.

Q: Does the extended temperature range of the AIRD-01-2R7N affect compatibility?

A: No. The AIRD-01-2R7N operating range (-40°C ~ 125°C) encompasses the original part's range (-25°C ~ 85°C). This provides additional thermal margin for applications operating at temperature extremes.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the AIRD-01-2R7M and AIRD-01-2R7N are RoHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial electronic applications.

Q: What is the physical dimension difference between these inductors?

A: Physical dimensions are essentially identical. Both parts measure 0.650" diameter (16.50 mm for the main part, 16.51 mm for the substitute) and 0.827" height (21.00 mm). These minor variations fall within standard manufacturing tolerances for the radial vertical cylinder package.
