Key Parameters

Substitute Part Grouping Explanation

Substitution of the AIRD-02-2R2M is determined by strict equivalence across the following critical parameters:

• Inductance Value: 2.2 µH (tolerance variations permitted within design specifications)
• Current Rating: 11.4 A minimum continuous current capacity
• DC Resistance: 4 mOhm maximum
• Core Type: Ferrite drum core construction
• Shielding Configuration: Unshielded
• Mounting: Through-hole radial vertical cylinder package
• Physical Dimensions: 0.827" diameter (21.00mm)
• Test Frequency: 1 kHz

The AIRD-02-2R2N qualifies as a direct substitute based on matching all critical electrical and mechanical parameters within the AIRD-02 series specification envelope.

Parameter Comparison

Engineering Selection Recommendations

The AIRD-02-2R2N is the manufacturer-recommended substitute for the obsolete AIRD-02-2R2M. Both components maintain identical electrical specifications for inductance, current rating, and DC resistance, with matching physical dimensions and core construction. The AIRD-02-2R2N offers an extended operating temperature range (-40°C to 125°C versus -25°C to 85°C) and is currently in active production status, ensuring long-term availability.

The inductance tolerance difference (±20% for AIRD-02-2R2M versus ±30% for AIRD-02-2R2N) must be evaluated within the context of circuit design requirements. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings, supporting equivalent environmental performance in production and field applications.

Frequently Asked Questions (FAQ)

Q: Can the AIRD-02-2R2N be used as a direct replacement for the AIRD-02-2R2M?

A: Yes. Both components share identical inductance values (2.2 µH), current ratings (11.4 A), DC resistance (4 mOhm max), core material (ferrite), shielding configuration (unshielded), and physical dimensions (0.827" diameter). Through-hole radial mounting is identical between both parts.

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

A: The AIRD-02-2R2M specifies ±20% tolerance, while the AIRD-02-2R2N specifies ±30% tolerance. Circuit designs requiring tighter inductance tolerance must account for this specification difference during component selection.

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

A: The AIRD-02-2R2N operates across -40°C to 125°C, compared to -25°C to 85°C for the AIRD-02-2R2M. This extended range provides greater operational flexibility and does not restrict compatibility in applications within the original part's temperature specification.

Q: Are there any compliance or certification differences?

A: Both components maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 1 - Unlimited). No compliance restrictions exist for substitution.

Q: Why is the AIRD-02-2R2M listed as obsolete?

A: The AIRD-02-2R2M has been superseded by the AIRD-02-2R2N within the manufacturer's product line. The AIRD-02-2R2N is the active production equivalent and is the recommended substitute for new designs and ongoing applications.
