Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AIRD-06-2R2M is determined by the following critical parameters:

Electrical Parameters (Must Match):

• Inductance value: 2.2 µH
• Current rating: 11.4 A minimum
• DC resistance: 4 mOhm maximum
• Saturation current: 68 A minimum
• Core material: Ferrite

Mechanical Parameters (Must Match):

• Mounting type: Through hole
• Package configuration: Radial, vertical cylinder
• Physical footprint: 0.827" diameter (21.00mm)

Allowable Variations:

• Inductance tolerance: ±20% to ±30% acceptable
• Operating temperature range: Extended ranges acceptable if minimum specifications met
• Q factor: Variations acceptable within frequency test conditions
• Product status: Active parts preferred over obsolete classifications

The AIRD-06-2R2N 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-06-2R2N is the recommended substitute for the obsolete AIRD-06-2R2M. Both components maintain identical electrical performance specifications including inductance value, current rating, DC resistance, and saturation current. Physical footprint and mounting configuration are identical, ensuring direct board-level compatibility.

The AIRD-06-2R2N offers the following advantages:

• Active product status ensures ongoing availability and manufacturer support
• Extended operating temperature range (-40°C ~ 125°C versus -25°C ~ 85°C) provides broader application flexibility
• Relaxed inductance tolerance (±30% versus ±20%) remains within acceptable circuit design margins for most applications
• Identical RoHS3 compliance and REACH unaffected status maintain regulatory alignment

Selection of the AIRD-06-2R2N eliminates supply chain risk associated with obsolete component sourcing while maintaining full electrical and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the AIRD-06-2R2N be used as a direct replacement for the AIRD-06-2R2M without circuit modification?

A: Yes. The AIRD-06-2R2N provides identical inductance value, current rating, DC resistance, and physical dimensions. Direct substitution is supported without circuit redesign or board layout changes.

Q: What is the significance of the inductance tolerance difference (±20% versus ±30%)?

A: The AIRD-06-2R2M specifies ±20% tolerance while the AIRD-06-2R2N specifies ±30%. For most filter, matching, and impedance applications, the ±30% tolerance remains within acceptable design margins. Applications requiring tighter inductance control should verify circuit performance with the relaxed tolerance specification.

Q: Does the extended operating temperature range of the AIRD-06-2R2N affect electrical performance?

A: The AIRD-06-2R2N maintains specified electrical parameters across -40°C ~ 125°C. The extended range provides design flexibility for applications operating outside the original -25°C ~ 85°C specification without performance degradation within the rated operating window.

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

A: Both components maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity ratings. No compliance or certification differences exist.

Q: Why is the AIRD-06-2R2M classified as obsolete?

A: Obsolescence classification indicates the manufacturer has discontinued active production. The AIRD-06-2R2N represents the current active equivalent within the AIRD-06 series, ensuring long-term supply chain continuity.

Q: What is the difference in Q factor measurement between the two parts?

A: The AIRD-06-2R2M specifies Q @ 50kHz while the AIRD-06-2R2N specifies Q @ 1kHz. Both maintain Q = 15 at their respective test frequencies. Q factor varies with frequency; the different test frequencies reflect measurement methodology rather than performance differences at equivalent operating conditions.
