Parameter Comparison

Engineering Selection Recommendations

Both the AISC-1008-3R3J-T and LQW2UAS3R3J00L maintain active product status and satisfy all regulatory compliance requirements including RoHS3, REACH, and EAR99 classification. The substitute part demonstrates equivalent electrical performance across all specified parameters. The LQW2UAS3R3J00L offers an extended lower operating temperature limit of -55°C compared to -40°C for the primary part, and a higher self-resonant frequency of 90MHz versus 70MHz. Both components are qualified for direct substitution in surface mount applications requiring 3.3 µH inductance at 290 mA current rating within the 1008 package format.

Frequently Asked Questions (FAQ)

Q: Can the LQW2UAS3R3J00L replace the AISC-1008-3R3J-T in all applications?

A: Yes, the substitute part meets all critical electrical and mechanical parameters. Both components share identical inductance (3.3 µH), tolerance (±5%), current rating (290 mA), DC resistance (3.4Ohm max), package format (1008), and compliance certifications. The substitute offers extended temperature range and higher self-resonant frequency.

Q: Are there physical dimension differences between these parts?

A: The AISC-1008-3R3J-T measures 0.115" L x 0.110" W x 0.090" H (2.92mm x 2.79mm x 2.29mm). The LQW2UAS3R3J00L measures 0.103" L x 0.096" W x 0.080" H (2.62mm x 2.45mm x 2.03mm). Both fit the 1008 (2520 Metric) package specification, though the substitute is slightly more compact.

Q: What is the difference between drum core and air core construction?

A: The AISC-1008-3R3J-T uses ceramic drum core construction, while the LQW2UAS3R3J00L uses air core construction. Both achieve the specified 3.3 µH inductance and 3.4Ohm DC resistance with identical electrical performance at the test frequency of 7.9 MHz.

Q: Are both parts suitable for high-frequency applications?

A: Both components are rated for high-frequency operation. The AISC-1008-3R3J-T has a self-resonant frequency of 70MHz, while the LQW2UAS3R3J00L reaches 90MHz, making the substitute suitable for applications requiring higher frequency performance.

Q: Do these parts require special handling or storage?

A: Both components have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
