Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AIRD-02-2R7M is determined by strict alignment of the following critical parameters:

• Inductance Value: 2.7 µH (tolerance variations permitted within electrical design margins)
• Current Rating: Minimum 11.4 A continuous current capability
• DC Resistance: Maximum 5 mOhm to maintain thermal and efficiency characteristics
• Core Material: Ferrite drum core construction
• Shielding Configuration: Unshielded design
• Mounting Interface: Through-hole radial vertical cylinder package
• Physical Footprint: 0.827" diameter (21.00 mm) to ensure PCB compatibility

The AIRD-02-2R7N qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while offering improved product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The AIRD-02-2R7N is the qualified substitute for the obsolete AIRD-02-2R7M. Both components maintain identical electrical performance specifications including inductance value, current rating, and DC resistance characteristics. The substitute part offers extended operating temperature range (-40°C to 125°C versus -25°C to 85°C), providing broader thermal operational capability for demanding environments.

Both parts maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. The AIRD-02-2R7N is currently in active production status with confirmed inventory availability, eliminating supply chain risk associated with the obsolete main part number.

The inductance tolerance difference (±20% versus ±30%) should be evaluated within specific circuit design requirements. Applications requiring tighter tolerance control may necessitate additional circuit compensation or selection screening.

Frequently Asked Questions (FAQ)

Q: Can the AIRD-02-2R7N be used as a direct replacement for the AIRD-02-2R7M in existing designs?

A: Yes. Both components share identical inductance values, current ratings, DC resistance specifications, and physical package dimensions. The substitute part is mechanically and electrically compatible for through-hole PCB mounting applications.

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

A: The main part specifies ±20% tolerance while the substitute specifies ±30%. This represents the manufacturing variation range for inductance values. Circuit designs should verify that the wider tolerance of the substitute part remains within acceptable operating parameters for the application.

Q: Does the extended operating temperature range of the AIRD-02-2R7N affect compatibility?

A: No. The substitute part's extended range (-40°C to 125°C) is a superset of the main part's range (-25°C to 85°C). Applications operating within the original temperature limits will function identically. Applications requiring extended temperature operation benefit from the substitute part's broader capability.

Q: Are there any compliance or certification differences between these parts?

A: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level ratings. No compliance differences exist between the main and substitute components.

Q: What is the physical footprint compatibility for PCB layout?

A: Both parts use identical radial vertical cylinder packages with 0.827" (21.00 mm) diameter dimensions. PCB footprints designed for the AIRD-02-2R7M require no modification for the AIRD-02-2R7N.
