Engineering Selection Recommendations

Both the AISC-1008-R027G-T and LQW2UAS27NG00L maintain Active product status with full ROHS3 compliance and REACH unaffected certification. Selection between these parts is based on availability, supply chain considerations, and application-specific requirements.

The LQW2UAS27NG00L from Murata Electronics provides an extended operating temperature range (-55°C to 125°C versus -40°C to 125°C) and a lower physical profile (0.080" seated height versus 0.090"), which may offer advantages in temperature-critical or space-constrained applications while maintaining all electrical equivalence parameters.

Both components are classified under ECCN EAR99 and HTSUS 8504.50.8000, with identical moisture sensitivity levels and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can LQW2UAS27NG00L be used as a direct replacement for AISC-1008-R027G-T?

A: Yes. Both parts meet identical electrical specifications (27 nH ±2%, 1 A rating, 130 mOhm DCR maximum, 55 Q @ 350 MHz, 1.6 GHz self-resonant frequency) and share the same 1008 (2520 Metric) package classification for surface mount assembly.

Q: Are there physical footprint differences between these parts?

A: Both components conform to the 1008 (2520 Metric) package specification. The Murata part exhibits slightly smaller length and width dimensions (2.62mm x 2.45mm versus 2.92mm x 2.79mm) and lower seated height (2.03mm versus 2.29mm), remaining within package tolerance limits. PCB layout compatibility is maintained.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the AISC-1008-R027G-T and LQW2UAS27NG00L carry ROHS3 compliance, REACH unaffected status, and identical ECCN and HTSUS classifications.

Q: What is the temperature operating range difference?

A: The AISC-1008-R027G-T operates from -40°C to 125°C. The LQW2UAS27NG00L extends the lower temperature limit to -55°C while maintaining the same 125°C upper limit. For applications requiring operation below -40°C, the Murata part provides extended capability.

Q: Are the DC resistance specifications identical?

A: Yes. Both parts specify a maximum DC resistance of 130 mOhm, ensuring equivalent copper loss characteristics and thermal performance in circuit applications.
