Substitute Part Grouping Explanation

Substitution of the AIRD-01-2R2M is determined by strict equivalence across the following critical parameters:

• Inductance Value: 2.2 µH (primary functional requirement)
• Current Rating: 9 A minimum continuous current capacity
• DC Resistance: 5 mOhm maximum (affects power dissipation and circuit performance)
• Core Type: Ferrite drum core construction
• Shielding Configuration: Unshielded
• Mounting Interface: Through-hole radial vertical cylinder package
• Saturation Current: 47 A minimum (defines safe operating margin)

The AIRD-01-2R2N qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Tolerance differences (±20% vs ±30%) and extended operating temperature range (-40°C ~ 125°C vs -25°C ~ 85°C) represent improvements in the substitute part, expanding application flexibility without compromising core functionality.

Parameter Comparison

Engineering Selection Recommendations

The AIRD-01-2R2N is the appropriate substitute for the obsolete AIRD-01-2R2M. Both components maintain identical electrical performance specifications for inductance, current rating, and DC resistance. The substitute part is currently in active production status, ensuring supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for new designs and manufacturing. The extended operating temperature range of the AIRD-01-2R2N (-40°C ~ 125°C) provides additional thermal margin compared to the original part (-25°C ~ 85°C), supporting deployment in wider environmental conditions without performance degradation.

Physical dimensions are equivalent within manufacturing tolerance, confirming direct mechanical compatibility in existing PCB layouts and mechanical assemblies. The ±30% inductance tolerance of the substitute part is wider than the original ±20% specification; circuit designs must verify that this tolerance range remains acceptable for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the AIRD-01-2R2N be used as a direct replacement for the AIRD-01-2R2M in existing designs?

A: Yes. Both parts share identical inductance values (2.2 µH), current ratings (9 A), DC resistance (5 mOhm max), core material (ferrite), shielding configuration (unshielded), and physical package dimensions. Through-hole mounting interfaces are compatible. Verify that the wider inductance tolerance (±30% vs ±20%) of the substitute part meets circuit performance requirements.

Q: What is the primary reason for substitution?

A: The AIRD-01-2R2M is obsolete and no longer manufactured. The AIRD-01-2R2N is the active production equivalent from the same manufacturer, providing identical electrical specifications and ensuring continued component availability.

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

A: Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical (MSL 1, Unlimited). No compliance barriers exist to substitution.

Q: Does the extended temperature range of the substitute part affect compatibility?

A: The AIRD-01-2R2N operates across -40°C ~ 125°C compared to the original -25°C ~ 85°C. This represents an expansion of the operating envelope and does not restrict compatibility. Applications operating within the original temperature range experience no adverse effects.

Q: Are physical dimensions identical?

A: Dimensions are equivalent within manufacturing tolerance. Both parts measure 0.650" diameter (16.50mm vs 16.51mm) and 0.827" maximum seated height (21.00mm). PCB footprints and mechanical clearances designed for the original part accommodate the substitute without modification.
