AIRD-02-1R5K Equivalent & Substitute Parts

Part Overview

The AIRD-02-1R5K is a 1.5 µH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 11.4 A continuous current with a maximum DC resistance of 3 mOhm. This through-hole radial component operates across -25°C to 85°C and is designed for applications requiring fixed inductance in compact form factors.

The AIRD-02-1R5K has reached obsolete product status. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AIRD-02-1R5K is determined by the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 1.5 µH
• Current rating: 11.4 A minimum
• Current saturation (Isat): 83 A
• DC resistance: 3 mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Through hole
• Package type: Radial, vertical cylinder
• Physical dimensions: 0.827" diameter (21.00 mm)

Allowable Variation Parameters:

• Inductance tolerance: May vary (±10% to ±30%)
• Operating temperature range: May extend beyond original specification
• Product status: Active status preferred for ongoing availability

The AIRD-02-1R5N qualifies as a direct substitute, maintaining all mandatory electrical and mechanical parameters while offering extended temperature range (-40°C ~ 125°C) and active product status for improved supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The AIRD-02-1R5N is the qualified substitute for the obsolete AIRD-02-1R5K. Both components maintain identical electrical performance specifications (1.5 µH inductance, 11.4 A current rating, 3 mOhm DCR, 83 A saturation current) and mechanical compatibility (through-hole radial package, 21.00 mm diameter).

The AIRD-02-1R5N offers two distinct advantages:

Product Status: Active manufacturing status ensures continued availability and supply chain reliability, eliminating the risk of component obsolescence.

Compliance & Certifications: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating. The substitute extends the operating temperature range to -40°C ~ 125°C, providing thermal margin for applications operating at temperature extremes.

The inductance tolerance difference (±10% vs. ±30%) reflects manufacturing specification variations within the AIRD-02 series. Applications requiring tighter tolerance control should evaluate circuit-level impact of the ±30% specification.

Frequently Asked Questions (FAQ)

Q: Can AIRD-02-1R5N directly replace AIRD-02-1R5K in existing designs?

A: Yes. Both components share identical inductance (1.5 µH), current rating (11.4 A), DC resistance (3 mOhm), saturation current (83 A), core material (ferrite), shielding (unshielded), and physical dimensions (0.827" diameter, 21.00 mm). Through-hole radial mounting is identical. No PCB layout or circuit modifications are required.

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

A: The AIRD-02-1R5K specifies ±10% tolerance while the AIRD-02-1R5N specifies ±30%. For applications where inductance value directly affects circuit performance (resonant frequency, impedance matching), evaluate whether the wider tolerance of the substitute meets design requirements. Circuit simulation or tolerance analysis may be necessary.

Q: Does the extended temperature range of AIRD-02-1R5N affect compatibility?

A: No. The substitute's extended operating range (-40°C ~ 125°C vs. -25°C ~ 85°C) is a superset of the original specification. Applications operating within the original temperature range experience no change in performance. Applications requiring operation at temperature extremes benefit from the extended range.

Q: Are there any compliance or certification differences?

A: No. Both components maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating. Regulatory and environmental compliance requirements are equivalent.

Q: What is the inventory status of each part?

A: AIRD-02-1R5K (obsolete) has 1119 pcs in stock. AIRD-02-1R5N (active) has 739 pcs in stock. For long-term supply assurance, the active status of AIRD-02-1R5N is preferred.
