AISC-0402-3N9J-T Equivalent & Substitute Parts

Part Overview

The AISC-0402-3N9J-T is a 3.9 nH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 840 mA continuous current with a maximum DC resistance of 66 mOhm. This surface mount component in 0402 (1005 Metric) package is designed for high-frequency applications up to 6 GHz self-resonant frequency. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AISC-0402-3N9J-T is determined by strict equivalence across the following critical parameters:

• Inductance value: 3.9 nH with ±5% tolerance
• Current rating: 840 mA minimum
• DC resistance: 66 mOhm maximum
• Package footprint: 0402 (1005 Metric) surface mount
• Core type: Ceramic drum core, wirewound, unshielded
• Operating temperature range: -40°C ~ 125°C
• Compliance: ROHS3 compliant

The substitute part LRW0402WJ3N9GG001T from Johanson Technology Inc. meets all these criteria and is therefore electrically and mechanically interchangeable.

Parameter Comparison

Engineering Selection Recommendations

Both the AISC-0402-3N9J-T and LRW0402WJ3N9GG001T are active production components with identical electrical and mechanical specifications. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Selection between these parts may be based on availability, packaging format (Abracon supplies in Tape & Reel; Johanson supplies in Cut Tape), or supply chain requirements. No technical performance differentiation exists between the two parts for applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can LRW0402WJ3N9GG001T be used as a direct replacement for AISC-0402-3N9J-T?

A: Yes. Both parts share identical inductance (3.9 nH ±5%), current rating (840 mA), DC resistance (66 mOhm max), package footprint (0402 / 1005 Metric), and operating temperature range (-40°C ~ 125°C). They are electrically and mechanically interchangeable.

Q: Are there differences in physical dimensions between these parts?

A: Minor dimensional variations exist. The AISC-0402-3N9J-T measures 0.047" L × 0.025" W (1.19mm × 0.64mm) with a seated height of 0.026" (0.66mm). The LRW0402WJ3N9GG001T measures 0.039" L × 0.022" W (1.00mm × 0.55mm) with a seated height of 0.024" (0.60mm). Both fit the 0402 package specification and are compatible with standard 0402 PCB footprints.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape wound on reels, suitable for automated assembly processes. Cut Tape packaging is supplied as individual segments cut from the carrier tape, suitable for manual assembly or smaller volume applications. Both formats contain identical components.

Q: Do both parts meet the same compliance standards?

A: Yes. Both AISC-0402-3N9J-T and LRW0402WJ3N9GG001T are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the self-resonant frequency difference between these parts?

A: The AISC-0402-3N9J-T has a self-resonant frequency of 6 GHz, while the LRW0402WJ3N9GG001T has 5.8 GHz. This difference does not affect substitution eligibility for applications operating within the specified inductance frequency test point of 250 MHz.
