Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AISC-0402-1N0J-T is determined by strict equivalence across the following critical parameters:

• Inductance value: 1 nH
• Current rating: 1.36 A minimum
• DC resistance: 45 mOhm maximum
• Package: 0402 (1005 Metric) surface mount
• Core type: Drum core, wirewound, ceramic
• Shielding configuration: Unshielded
• Operating temperature range: -40°C to 125°C minimum
• Frequency characteristics: Q @ 250 MHz and self-resonant frequency

The AISC-0402-1N0S-T qualifies as a direct substitute based on identical electrical specifications, mechanical dimensions, and thermal performance. The primary distinction is product status transition from obsolete to active production.

Parameter Comparison

Engineering Selection Recommendations

The AISC-0402-1N0S-T is the direct equivalent for AISC-0402-1N0J-T replacement. Both components maintain identical electrical performance, mechanical compatibility, and thermal specifications. The substitute part is currently in active production status, ensuring supply chain continuity and availability for both new designs and legacy system support.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The tolerance specification difference (±5% versus ±0.3 nH) reflects manufacturing process refinement in the active production variant, with the substitute offering tighter inductance tolerance.

Frequently Asked Questions (FAQ)

Q: Can AISC-0402-1N0S-T be used as a direct replacement for AISC-0402-1N0J-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters including inductance, current rating, DC resistance, frequency response, and thermal operating range. The 0402 package dimensions and surface mount configuration are identical.

Q: What is the significance of the tolerance difference between the two parts?

A: The main part specifies ±5% tolerance while the substitute specifies ±0.3 nH absolute tolerance. For a 1 nH inductor, ±0.3 nH represents approximately ±30%, making the substitute's tolerance specification less restrictive in absolute terms. Both tolerances are acceptable for the same circuit applications.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited). Regulatory and environmental certifications are equivalent.

Q: Why is the main part marked as obsolete?

A: Product status reflects manufacturing lifecycle decisions. The AISC-0402-1N0S-T represents the current production variant of the same component specification, ensuring continued availability and supply chain support.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical 0402 (1005 Metric) package dimensions: 0.047" L × 0.025" W (1.19 mm × 0.64 mm) with maximum seated height of 0.026" (0.66 mm).
