Key Parameters

Substitute Part Grouping Explanation

Substitution of the AIRD-02-8R2K is determined by strict equivalence across the following critical parameters:

• Inductance value: 8.2 µH
• Current rating: 11.4 A minimum
• DC resistance: 7 mOhm maximum
• Saturation current: 36 A minimum
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Through hole radial
• Physical package: Vertical cylinder form factor
• Operating temperature range: -25°C to 85°C minimum
• Compliance certifications: ROHS3, REACH Unaffected

The AIRD-02-8R2M qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is product status and tolerance specification, which do not affect functional equivalence in applications where the component specifications are met.

Parameter Comparison

Engineering Selection Recommendations

The AIRD-02-8R2M is the manufacturer-recommended substitute for the obsolete AIRD-02-8R2K. Both components maintain identical electrical performance specifications, physical dimensions, and compliance certifications. The AIRD-02-8R2M is currently in active production status with confirmed inventory availability, ensuring supply chain reliability for new designs and production continuity.

The tolerance specification difference (±10% versus ±20%) should be evaluated against application requirements. Applications with strict inductance tolerance requirements may require circuit-level compensation or selection screening. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can AIRD-02-8R2M be used as a direct replacement for AIRD-02-8R2K in existing designs?

A: Yes. The AIRD-02-8R2M is electrically and mechanically equivalent. All critical parameters including inductance, current rating, DC resistance, saturation current, core material, shielding, mounting type, and physical dimensions are identical. The component will function identically in the same circuit application.

Q: What is the difference between the ±10% and ±20% tolerance specifications?

A: Tolerance defines the acceptable range of inductance variation from the nominal 8.2 µH value. AIRD-02-8R2K specifies ±10% (7.38 µH to 9.02 µH), while AIRD-02-8R2M specifies ±20% (6.56 µH to 9.84 µH). Applications requiring tighter inductance control should verify that the ±20% tolerance of the substitute part meets circuit performance requirements.

Q: Are there packaging differences between these parts?

A: The AIRD-02-8R2K is supplied in standard packaging, while the AIRD-02-8R2M is supplied in bulk packaging. Both maintain identical component specifications and physical form factor. Packaging differences do not affect electrical or mechanical performance.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both AIRD-02-8R2K and AIRD-02-8R2M are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: What is the current availability status of these parts?

A: AIRD-02-8R2K is obsolete with limited remaining inventory (889 pieces). AIRD-02-8R2M is in active production with confirmed inventory availability (956 pieces), providing reliable supply for ongoing requirements.
