Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AIRD-01-1R2M is determined by the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 1.2 µH
• Current rating: 9 A minimum
• DC resistance: 3 mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Through Hole
• Package type: Radial, Vertical Cylinder
• Current saturation: 68 A minimum

Allowable Variations:

• Inductance tolerance: ±20% to ±30% acceptable
• Operating temperature range: Extended ranges acceptable if minimum specifications met
• Physical dimensions: Minor variations within package class acceptable (±0.01" tolerance)
• Product status: Active parts preferred for obsolete components

The AIRD-01-1R2N qualifies as a direct substitute based on matching all mandatory electrical and mechanical parameters while offering improved product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The AIRD-01-1R2N is the qualified substitute for the obsolete AIRD-01-1R2M. Both components maintain identical electrical performance specifications including inductance value, current rating, and DC resistance. The substitute part offers extended operating temperature range (-40°C ~ 125°C versus -25°C ~ 85°C), providing greater thermal margin for demanding applications.

Both parts maintain full compliance with ROHS3 and REACH regulatory requirements. Physical dimensions are equivalent within standard manufacturing tolerances. The primary advantage of the AIRD-01-1R2N is active product status, ensuring continued availability and supply chain stability compared to the obsolete AIRD-01-1R2M.

Frequently Asked Questions (FAQ)

Q: Can AIRD-01-1R2N be used as a direct replacement for AIRD-01-1R2M in existing designs?

A: Yes. Both parts share identical inductance values, current ratings, DC resistance specifications, and physical dimensions. The substitute part is pin-compatible and functionally equivalent for all applications where the original part was specified.

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

A: The AIRD-01-1R2M specifies ±20% tolerance, while the AIRD-01-1R2N specifies ±30% tolerance. Both tolerances are within acceptable ranges for typical inductor applications. Circuit designs should account for the wider tolerance of the substitute part if inductance precision is critical.

Q: Does the extended operating temperature range of AIRD-01-1R2N affect compatibility?

A: No. The extended range (-40°C ~ 125°C) of the substitute part is a superset of the original part's range (-25°C ~ 85°C). Applications operating within the original temperature specification remain fully compatible.

Q: Are there any physical dimension differences between these parts?

A: Dimensions are equivalent. Both parts measure 0.650" diameter and 0.827" maximum seated height. The diameter specification differs by 0.01mm (16.50mm versus 16.51mm), which is within standard manufacturing tolerance and does not affect PCB layout or mechanical fit.

Q: What is the significance of the product status change from Obsolete to Active?

A: Active product status indicates the AIRD-01-1R2N is in current production with guaranteed long-term availability. This eliminates supply chain risk associated with obsolete components and ensures consistent quality and delivery for ongoing production requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both AIRD-01-1R2M and AIRD-01-1R2N are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
