AISC-0805-R033G-T Equivalent & Substitute Parts

Part Overview

The AISC-0805-R033G-T is a 33 nH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 500 mA continuous current with a maximum DC resistance of 270 mOhm. This component is designed for surface mount applications in the 0805 (2012 Metric) package format and is currently in active production status. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same inductance value, current rating, tolerance, and package class.

Substitute Part Grouping Explanation

Substitution eligibility for the AISC-0805-R033G-T is determined by strict equivalence across the following critical parameters:

Inductance Value: 33 nH (exact match required)
Tolerance: ±2% (exact match required)
Current Rating: 500 mA (exact match required)
DC Resistance: 270 mOhm maximum (exact match required)
Shielding Configuration: Unshielded (exact match required)
Package Classification: 0805 form factor (2012 or 2015 Metric variants acceptable)
Q Factor: 60 @ 500 MHz (exact match required)
Compliance: ROHS3 Compliant, MSL 1, REACH Unaffected

The LQW2BAS33NG00L from Murata Electronics meets all substitution criteria. Both components are wirewound inductors with identical electrical performance specifications and compatible surface mount packaging. The substitute part operates across an extended lower temperature range (-55°C vs. -40°C minimum) and exhibits a marginally higher self-resonant frequency (2.15 GHz vs. 2 GHz), both of which represent equivalent or superior performance characteristics.

Engineering Selection Recommendations

Both the AISC-0805-R033G-T and LQW2BAS33NG00L are active production components with full ROHS3 compliance and REACH unaffected status, making either suitable for new designs and production environments. The Murata LQW2BAS33NG00L offers extended lower temperature operation (-55°C minimum vs. -40°C) and is available in higher inventory quantities (2968 pcs vs. 991 pcs). The Abracon AISC-0805-R033G-T maintains identical electrical performance with established supply chain presence in the AISC-0805 series. Selection between these parts should be based on availability, lead time, packaging preference (Cut Tape vs. Tape & Reel), and specific thermal operating requirements of the application.

Frequently Asked Questions (FAQ)

Q: Can the LQW2BAS33NG00L replace the AISC-0805-R033G-T in existing designs?

A: Yes. Both components share identical inductance (33 nH), tolerance (±2%), current rating (500 mA), DC resistance (270 mOhm max), and Q factor (60 @ 500 MHz) specifications. The 0805 package variants (2012 vs. 2015 Metric) are mechanically compatible with equivalent footprint dimensions and height profiles suitable for standard PCB assembly processes.

Q: What are the physical dimension differences between these parts?

A: The Abracon AISC-0805-R033G-T measures 0.090" L x 0.068" W x 0.061" H (2.29mm x 1.73mm x 1.55mm). The Murata LQW2BAS33NG00L measures 0.082" L x 0.060" W x 0.060" H (2.09mm x 1.53mm x 1.52mm). Both fit within standard 0805 package specifications and are compatible with existing PCB layouts.

Q: Are there temperature range considerations for substitution?

A: The Murata substitute operates from -55°C to 125°C, extending the lower temperature limit by 15°C compared to the Abracon part (-40°C to 125°C). This provides additional margin for applications requiring extended cold-temperature performance. Both parts maintain identical electrical characteristics across their respective operating ranges.

Q: What packaging formats are available for each part?

A: The AISC-0805-R033G-T is supplied in Cut Tape (CT) packaging. The LQW2BAS33NG00L is supplied in Tape & Reel (TR) packaging. Selection depends on assembly process requirements and volume considerations.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH unaffected. They share identical ECCN (EAR99) and HTSUS (8504.50.8000) classifications.
