Key Parameters

Substitute Part Grouping Explanation

Substitution of the AIRD-02-1R2M is determined by the following critical parameters:

• Inductance Value: 1.2 µH (exact match required)
• Current Rating: 11.4 A minimum (continuous current capacity)
• Current - Saturation (Isat): 108 A minimum (saturation threshold)
• DC Resistance (DCR): 3 mOhm maximum (resistance specification)
• Core Material: Ferrite (electromagnetic performance)
• Shielding: Unshielded (EMI characteristics)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Package / Case: Radial, Vertical Cylinder (physical form factor)
• Physical Dimensions: 0.827" Dia (21.00mm) (board layout fit)

The AIRD-02-1R2N meets all critical substitution criteria and is classified as an active product within the same AIRD-02 series.

Parameter Comparison

Engineering Selection Recommendations

The AIRD-02-1R2N is a direct functional substitute for the AIRD-02-1R2M. Both components share identical electrical specifications for inductance, current rating, saturation current, and DC resistance. Both are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 classification.

The AIRD-02-1R2N offers an extended operating temperature range (-40°C ~ 125°C versus -25°C ~ 85°C) and maintains active product status with higher inventory availability. The inductance tolerance specification differs (±30% versus ±20%), which is acceptable for applications where the original ±20% tolerance is not a critical design constraint.

Physical form factor, mounting type, and package dimensions are identical, ensuring direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the AIRD-02-1R2N replace the AIRD-02-1R2M in existing designs?

A: Yes. The AIRD-02-1R2N meets all critical electrical and mechanical specifications of the AIRD-02-1R2M. Identical inductance value, current rating, saturation current, DC resistance, core material, shielding, mounting type, and physical dimensions ensure functional equivalence. The component can be substituted without PCB redesign.

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

A: The AIRD-02-1R2M specifies ±20% inductance tolerance, while the AIRD-02-1R2N specifies ±30%. For applications where inductance tolerance is not a critical design parameter, this difference is acceptable. For designs requiring tighter tolerance control, the original specification should be verified against circuit performance requirements.

Q: Does the extended operating temperature range of the AIRD-02-1R2N affect compatibility?

A: No. The AIRD-02-1R2N operating range (-40°C ~ 125°C) encompasses the AIRD-02-1R2M range (-25°C ~ 85°C). This represents an improvement in thermal capability and does not introduce compatibility issues for applications operating within the original temperature specification.

Q: Are there any compliance or regulatory differences?

A: No. Both components are ROHS3 compliant, REACH unaffected, and carry identical MSL Level 1 classification. Regulatory and environmental compliance requirements are equivalent.

Q: Why is the AIRD-02-1R2M classified as obsolete?

A: The AIRD-02-1R2M has been superseded by the AIRD-02-1R2N within the AIRD-02 series. The newer variant maintains electrical and mechanical compatibility while offering extended temperature range and active product status with improved supply availability.
