Substitute Part Grouping Explanation

Substitution eligibility for the AIRD-06-2R7M is determined by the following critical parameters:

Mandatory Match Criteria:

• Inductance value: 2.7 µH
• Current rating: 11.4 A minimum
• DC resistance: 5 mOhm maximum
• Core material: Ferrite
• Mounting type: Through hole radial configuration
• Physical dimensions: 0.827" diameter × 0.827" height maximum
• Shielding: Unshielded

Allowable Variations:

• Inductance tolerance: ±20% to ±30% acceptable
• Saturation current (Isat): 58 A or higher
• Operating temperature range: Extended ranges acceptable if minimum -25°C and maximum ≥85°C
• Q factor: Variations acceptable within ferrite drum core specifications

The AIRD-06-2R7N qualifies as a direct substitute based on identical inductance, current rating, DCR, core type, and physical dimensions, with extended operating temperature range and improved product status.

Engineering Selection Recommendations

The AIRD-06-2R7N is the qualified substitute for the obsolete AIRD-06-2R7M. Selection is based on the following engineering factors:

Product Status: The AIRD-06-2R7N maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete AIRD-06-2R7M.

Electrical Equivalence: Both parts maintain identical inductance (2.7 µH), current rating (11.4 A), DC resistance (5 mOhm max), and saturation current (58 A). The inductance tolerance variance from ±20% to ±30% remains within acceptable engineering margins for fixed inductor applications.

Thermal Performance: The AIRD-06-2R7N provides an extended operating temperature range (-40°C ~ 125°C) compared to the main part (-25°C ~ 85°C), offering improved thermal margin for demanding environments.

Regulatory Compliance: Both components maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 1), ensuring regulatory equivalence.

Physical Compatibility: Identical package dimensions (0.827" diameter × 0.827" height) and through-hole radial mounting configuration ensure direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the AIRD-06-2R7N be used as a direct replacement for the AIRD-06-2R7M in existing designs?

A: Yes. The AIRD-06-2R7N is electrically and mechanically equivalent. Identical inductance, current rating, DC resistance, and physical dimensions ensure direct substitution without circuit redesign or PCB layout changes.

Q: What is the significance of the inductance tolerance change from ±20% to ±30%?

A: The tolerance variance remains within acceptable engineering margins for fixed inductor applications. Both tolerances fall within standard ferrite drum core specifications. Circuit designs accounting for ±20% tolerance will operate within acceptable parameters with ±30% tolerance components.

Q: Does the extended operating temperature range of the AIRD-06-2R7N affect compatibility?

A: No. The extended range (-40°C ~ 125°C versus -25°C ~ 85°C) provides additional thermal margin and is fully backward compatible. Applications operating within the original temperature range experience no performance change.

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

A: No. Both components maintain identical RoHS3 compliance, REACH unaffected status, moisture sensitivity levels, and regulatory classifications (ECCN EAR99, HTSUS 8504.50.8000).

Q: What inventory considerations apply to this substitution?

A: The AIRD-06-2R7N is currently in active production with 1,165 units in stock, compared to the obsolete AIRD-06-2R7M with 912 units remaining. The active status ensures continued availability for future production requirements.

Q: Are there any application-specific limitations for the AIRD-06-2R7N?

A: No application-specific limitations exist. The substitute maintains all electrical and mechanical parameters required for the original design specifications.
