Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AIRD-02-2R7K is determined by the following critical parameters:

• Inductance Value: 2.7 µH (exact match required)
• Current Rating: 11.4 A minimum (equal or higher acceptable)
• DC Resistance: 5 mOhm maximum (equal or lower acceptable)
• Core Material: Ferrite (must match)
• Shielding Configuration: Unshielded (must match)
• Mounting Type: Through Hole (must match)
• Package Configuration: Radial, Vertical Cylinder (must match)
• Physical Dimensions: 0.827" diameter (21.00 mm) (must match)

The AIRD-02-2R7N qualifies as a direct substitute, maintaining identical electrical performance specifications and physical form factor while offering active product status and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The AIRD-02-2R7N is the primary substitute for the obsolete AIRD-02-2R7K. Both components maintain identical electrical specifications for inductance, current rating, and DC resistance, ensuring functional equivalence in circuit applications.

Key advantages of the AIRD-02-2R7N:

• Active product status ensures ongoing availability and manufacturing support
• Extended operating temperature range (-40°C ~ 125°C versus -25°C ~ 85°C) provides broader thermal operating envelope
• Maintained ROHS3 compliance and REACH unaffected status
• Identical physical form factor and mounting configuration
• Same saturation current rating (58 A)

The inductance tolerance difference (±10% versus ±30%) should be evaluated against circuit design requirements. Applications with strict inductance tolerance specifications may require circuit validation or component selection procedures.

Frequently Asked Questions (FAQ)

Q: Can the AIRD-02-2R7N be used as a direct replacement for the AIRD-02-2R7K?

A: Yes. Both components share identical inductance values (2.7 µH), current ratings (11.4 A), DC resistance (5 mOhm max), core material (ferrite), shielding configuration (unshielded), and physical dimensions (0.827" diameter). The AIRD-02-2R7N is electrically and mechanically compatible for direct substitution.

Q: What is the significance of the inductance tolerance difference?

A: The AIRD-02-2R7K specifies ±10% tolerance while the AIRD-02-2R7N specifies ±30% tolerance. For applications requiring tighter inductance accuracy, component selection or circuit compensation may be necessary. Verify tolerance requirements against circuit design specifications.

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

A: No. Both components maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 1 - Unlimited) is identical for both parts.

Q: What is the advantage of the extended temperature range in the AIRD-02-2R7N?

A: The AIRD-02-2R7N operates from -40°C to 125°C compared to the AIRD-02-2R7K range of -25°C to 85°C. This extended range accommodates applications with broader thermal operating requirements or harsh environmental conditions.

Q: Are the physical dimensions identical?

A: Yes. Both components feature 0.827" (21.00 mm) diameter radial, vertical cylinder packages. PCB layout and mounting hole spacing remain unchanged.
