AISC-1008-2R2J-T Equivalent & Substitute Parts

Part Overview

The AISC-1008-2R2J-T is a 2.2 µH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 280 mA with a maximum DC resistance of 2.8Ohm. This surface mount component is designed for applications requiring fixed inductance in compact 1008 (2520 Metric) package form factor. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package standard.

Engineering Selection Recommendations

Both the AISC-1008-2R2J-T and LQW2UAS2R2J00L are active production parts with full RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and deployment.

The Murata LQW2UAS2R2J00L substitute offers an extended lower operating temperature limit of -55°C compared to the Abracon part's -40°C minimum, providing broader thermal operating range coverage. The Murata part also demonstrates a higher self-resonant frequency of 130MHz versus 100MHz, which may provide performance advantages in high-frequency applications.

Physical dimensions differ slightly between the two parts. The Murata substitute is more compact, measuring 0.103" L x 0.096" W with a maximum seated height of 0.080", compared to the Abracon part at 0.115" L x 0.110" W with 0.090" height. Both remain within the 1008 (2520 Metric) package specification and maintain identical footprint compatibility for PCB placement.

Selection between these parts should be based on supply chain availability, procurement lead times, and specific application thermal or frequency requirements within the defined operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the LQW2UAS2R2J00L replace the AISC-1008-2R2J-T in existing designs?

A: Yes. Both parts share identical inductance (2.2 µH ±5%), current rating (280 mA), DC resistance (2.8Ohm max), and package footprint (1008 / 2520 Metric). PCB layout and schematic compatibility are maintained.

Q: What are the key differences between these substitute parts?

A: The primary differences are core material composition (Abracon uses ceramic drum core; Murata uses air core), self-resonant frequency (100MHz vs. 130MHz), operating temperature range (-40°C to 125°C vs. -55°C to 125°C), and physical dimensions. Electrical performance at rated specifications remains equivalent.

Q: Are both parts RoHS3 compliant?

A: Yes. Both AISC-1008-2R2J-T and LQW2UAS2R2J00L are ROHS3 compliant with REACH unaffected status.

Q: Does the physical size difference affect PCB assembly?

A: The Murata part is slightly more compact. Verify PCB layout clearances and component placement constraints. Both parts use identical 1008 (2520 Metric) surface mount package specifications and standard pick-and-place equipment compatibility.

Q: What is the moisture sensitivity rating for both parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
