AISC-0805-R12G-T Equivalent & Substitute Parts

Part Overview

The AISC-0805-R12G-T is a 120 nH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 400 mA continuous current with a maximum DC resistance of 510 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AISC-0805-R12G-T is determined by strict equivalence across the following critical parameters:

Inductance value must be 120 nH with ±2% tolerance. Current rating must be rated for minimum 400 mA. DC resistance maximum must not exceed 510 mOhm. Self-resonant frequency must be 1.1 GHz. Q factor at 250 MHz must be 50. Shielding configuration must be unshielded. Package classification must be 0805 format (2012 or 2015 Metric variants). Surface mount mounting type is required. RoHS3 compliance and MSL 1 rating must be maintained.

The substitute part LQW2BASR12G00L from Murata Electronics meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the AISC-0805-R12G-T and LQW2BASR12G00L are active production components with ROHS3 compliance and identical electrical specifications for inductance, tolerance, current rating, and DC resistance. The primary distinction is the operating temperature range: the Abracon part supports -40°C to 125°C, while the Murata part supports -40°C to 85°C. Selection between these parts should be based on the application's thermal requirements. For applications operating above 85°C, the AISC-0805-R12G-T is the appropriate choice. For applications within the -40°C to 85°C range, either part is suitable. Both components carry MSL 1 rating and are suitable for unlimited moisture exposure conditions.

Frequently Asked Questions (FAQ)

Q: Can the LQW2BASR12G00L replace the AISC-0805-R12G-T in all applications?

A: The LQW2BASR12G00L is electrically equivalent for inductance, current rating, and DC resistance. However, the operating temperature range differs. The Murata part is limited to -40°C to 85°C, while the Abracon part operates to 125°C. Substitution is valid only for applications within the lower temperature range.

Q: Are there physical size differences between the 0805 (2012 Metric) and 0805 (2015 Metric) packages?

A: Yes. The Abracon AISC-0805-R12G-T measures 0.090" L x 0.068" W (2.29mm x 1.73mm) with a seated height of 0.061" (1.55mm). The Murata LQW2BASR12G00L measures 0.082" L x 0.060" W (2.09mm x 1.53mm) with a seated height of 0.060" (1.52mm). Both fit the 0805 package footprint, but the Murata part is slightly smaller. Verify PCB layout clearances if space constraints exist.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the AISC-0805-R12G-T and LQW2BASR12G00L carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both components are ROHS3 compliant and carry identical REACH Unaffected and EAR99 ECCN classifications.
