Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AIRD-02-2R2K is determined by the following critical parameters:

• Inductance Value: Must be 2.2 µH (tolerance variations are acceptable within design margins)
• Current Rating: Must support minimum 11.4 A continuous current
• DC Resistance: Must not exceed 4 mOhm maximum
• Core Material: Ferrite drum core construction
• Shielding Configuration: Unshielded
• Mounting Interface: Through-hole radial mounting
• Physical Form Factor: Radial vertical cylinder package with 0.827" (21.00 mm) diameter

The AIRD-02-2R2N meets all substitution criteria as an active production alternative within the same AIRD-02 series, maintaining identical electrical performance specifications and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AIRD-02-2R2N is the direct substitute for the obsolete AIRD-02-2R2K. Both components maintain identical electrical and mechanical specifications across all critical parameters: inductance value, current rating, DC resistance, core material, shielding configuration, and physical form factor.

The AIRD-02-2R2N offers extended operational temperature range (-40°C ~ 125°C versus -25°C ~ 85°C), providing enhanced thermal performance for demanding applications. The wider inductance tolerance (±30% versus ±10%) is acceptable for most circuit applications where the primary function is current limiting or EMI filtering rather than precision resonant frequency tuning.

Both components maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility for current manufacturing standards. The AIRD-02-2R2N is currently in active production with established supply availability, eliminating obsolescence risk associated with the original part number.

Frequently Asked Questions (FAQ)

Q: Can the AIRD-02-2R2N be used as a direct replacement for the AIRD-02-2R2K?

A: Yes. Both components share identical inductance values (2.2 µH), current ratings (11.4 A), DC resistance specifications (4 mOhm max), core materials (ferrite), and physical dimensions (0.827" diameter radial vertical cylinder). Through-hole mounting compatibility is maintained.

Q: What is the significance of the inductance tolerance difference (±10% versus ±30%)?

A: The AIRD-02-2R2K specifies ±10% tolerance while the AIRD-02-2R2N specifies ±30%. For applications where inductance value precision is critical to circuit function, this difference must be evaluated against design margin requirements. For current limiting, filtering, and general impedance applications, the wider tolerance is typically acceptable.

Q: Does the extended temperature range of the AIRD-02-2R2N affect compatibility?

A: The AIRD-02-2R2N operates across -40°C ~ 125°C compared to the AIRD-02-2R2K range of -25°C ~ 85°C. This represents an enhancement that expands application capability without reducing compatibility. Designs operating within the original temperature range remain fully compatible.

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

A: Both components maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 1 - Unlimited) is identical. No compliance barriers exist to substitution.

Q: What is the availability status of each part?

A: The AIRD-02-2R2K is obsolete with limited remaining inventory (725 pcs). The AIRD-02-2R2N is in active production with established supply (1120 pcs available). For new designs and ongoing production, the AIRD-02-2R2N is the recommended selection.
