AISC-0805-R18G-T Equivalent & Substitute Parts

Part Overview

The AISC-0805-R18G-T is a 180 nH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 400 mA continuous current with a maximum DC resistance of 640 mOhm. This surface mount component operates across the temperature range of -40°C to 125°C and is designed for high-frequency applications up to 870 MHz self-resonant frequency. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and performance envelope.

Substitute Part Grouping Explanation

Substitution between AISC-0805-R18G-T and LQW2BASR18G00L is valid based on the following matched electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 180 nH (both parts)
• Inductance tolerance: ±2% (both parts)
• Current rating: 400 mA (both parts)
• DC resistance: 640 mOhm maximum (both parts)
• Shielding configuration: Unshielded (both parts)
• Q factor: 50 @ 250 MHz (both parts)
• Package footprint: 0805 surface mount (both parts)
• Mounting type: Surface mount (both parts)
• Regulatory compliance: ROHS3 compliant, REACH unaffected (both parts)
• Moisture sensitivity: MSL 1 (both parts)

Allowable Variations:

• Self-resonant frequency: 870 MHz (AISC) vs. 920 MHz (LQW2) — both exceed application requirements
• Operating temperature upper limit: 125°C (AISC) vs. 85°C (LQW2) — application-dependent consideration
• Physical dimensions: Minor variations within 0805 package specification
• Packaging format: Tape & Reel vs. Cut Tape & Digi-Reel — logistics consideration only

Parameter Comparison

Engineering Selection Recommendations

Both AISC-0805-R18G-T and LQW2BASR18G00L are active production components with full RoHS3 compliance and REACH unaffected status, making either suitable for new designs and existing production environments. Selection between these parts should be based on:

Primary Consideration: Operating temperature requirement. The AISC-0805-R18G-T supports operation to 125°C, while the LQW2BASR18G00L is rated to 85°C maximum. Applications requiring sustained operation above 85°C must use the Abracon part.

Secondary Consideration: Availability and supply chain. The LQW2BASR18G00L currently has higher inventory (7350 pcs) compared to AISC-0805-R18G-T (1162 pcs), which may influence procurement decisions for high-volume production.

Tertiary Consideration: Packaging format. The AISC-0805-R18G-T is supplied in Tape & Reel format, while the LQW2BASR18G00L is available in Cut Tape & Digi-Reel format. Selection depends on assembly equipment compatibility and handling requirements.

All other electrical and mechanical parameters are equivalent, ensuring functional interchangeability within the specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can LQW2BASR18G00L replace AISC-0805-R18G-T in all applications?

A: Substitution is valid for applications operating at or below 85°C. Applications requiring operation above 85°C must use AISC-0805-R18G-T, which is rated to 125°C.

Q: Are the physical dimensions identical between these parts?

A: Both parts use the 0805 surface mount package. The AISC-0805-R18G-T measures 0.090" L × 0.068" W (2.29mm × 1.73mm) with 0.061" seated height. The LQW2BASR18G00L measures 0.082" L × 0.060" W (2.09mm × 1.53mm) with 0.060" seated height. These minor variations remain within 0805 package specifications and are compatible with standard PCB footprints.

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

A: The AISC-0805-R18G-T uses drum core construction, while the LQW2BASR18G00L uses standard wirewound construction. Both achieve the same electrical specifications (180 nH, 400 mA, 640 mOhm DCR) and are functionally equivalent for this application.

Q: Do both parts have the same self-resonant frequency?

A: No. AISC-0805-R18G-T has a self-resonant frequency of 870 MHz, while LQW2BASR18G00L is rated at 920 MHz. Both values exceed typical application requirements for 180 nH inductors and do not affect substitution validity.

Q: Are there any compliance or regulatory differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1, unlimited). No compliance barriers exist for substitution.

Q: What packaging options are available?

A: AISC-0805-R18G-T is supplied in Tape & Reel (TR) format. LQW2BASR18G00L is supplied in Cut Tape (CT) & Digi-Reel format. Packaging selection depends on assembly line equipment and volume requirements.
