Key Parameters

Substitute Part Grouping Explanation

Substitution of the AISC-0402-1N2J-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 1.2 nH
• Package / Case: 0402 (1005 Metric)
• Mounting Type: Surface Mount
• Current Rating: 1.3 A minimum
• DC Resistance: 60 mOhm maximum
• Operating Temperature Range: -40°C to 125°C minimum
• Core Material: Ceramic
• Shielding Configuration: Unshielded

Allowable Variation Parameters:

• Inductance Tolerance: May vary from ±5% to ±10% depending on application requirements
• Product Status: Active status substitutes are preferred for obsolete components

The AISC-0402-1N2K-T meets all mandatory matching parameters and represents a direct functional substitute with identical electrical performance characteristics and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

The AISC-0402-1N2K-T is a direct substitute for the obsolete AISC-0402-1N2J-T. Both components are manufactured by Abracon LLC within the same AISC-0402 series and share identical electrical specifications and physical dimensions.

Primary Advantage of Substitution: The AISC-0402-1N2K-T carries Active product status, ensuring continued availability and supply chain support. This addresses the obsolescence constraint of the original component while maintaining full functional equivalence.

Tolerance Consideration: The substitute part features ±10% inductance tolerance compared to the original ±5% tolerance. Applications requiring the tighter ±5% tolerance specification must evaluate whether the ±10% tolerance remains acceptable for circuit performance. Both tolerance grades fall within standard inductor manufacturing practices for this package class.

Compliance Status: Both components maintain ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for current manufacturing and deployment environments.

Frequently Asked Questions (FAQ)

Q: Can the AISC-0402-1N2K-T be used as a direct replacement for the AISC-0402-1N2J-T?

A: Yes. The AISC-0402-1N2K-T is a direct functional substitute. Both components share identical inductance values (1.2 nH), current ratings (1.3 A), DC resistance specifications (60 mOhm max), and physical dimensions (0402 package). The primary difference is product status (Active vs. Obsolete) and inductance tolerance (±10% vs. ±5%).

Q: What is the significance of the tolerance difference between ±5% and ±10%?

A: Inductance tolerance defines the acceptable range of actual inductance values around the nominal 1.2 nH specification. The ±5% tolerance provides a tighter range (1.14 nH to 1.26 nH), while ±10% allows a wider range (1.08 nH to 1.32 nH). Applications with strict frequency response or impedance matching requirements must confirm that the ±10% tolerance remains within acceptable circuit performance margins.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both the AISC-0402-1N2J-T and AISC-0402-1N2K-T are packaged in the 0402 (1005 Metric) surface mount format with identical dimensions of 0.047" L x 0.025" W (1.19 mm x 0.64 mm) and maximum seated height of 0.026" (0.66 mm). PCB layout and assembly processes require no modification.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and deployment.

Q: What is the operational frequency range for these inductors?

A: Both components are characterized at 250 MHz with a self-resonant frequency of 12 GHz. The Q factor at 250 MHz is 13 for both parts. These specifications define the frequency range where the inductor maintains predictable performance characteristics.

Q: Is the AISC-0402-1N2K-T available in sufficient quantity for production requirements?

A: Inventory status is subject to real-time availability. The AISC-0402-1N2K-T carries Active product status, indicating ongoing manufacturing and distribution support through Abracon LLC and authorized distributors.
