Differences in current rating and DC resistance are noted in the parameter comparison table and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 744761156C and LQW18AN56NJ00D are active production parts with ROHS3 compliance and MSL 1 rating. Selection between these parts depends on application-specific current and resistance requirements:

The 744761156C is suitable for applications requiring the full 600 mA current rating and lower DC resistance of 250mOhm maximum.

The LQW18AN56NJ00D is suitable for applications with current requirements up to 360 mA and where the higher Q factor (38 @ 200MHz) and extended self-resonant frequency (2.4 GHz) provide performance advantages. The wider operating temperature range (-55°C ~ 125°C) supports extended environmental specifications.

Both parts maintain identical inductance tolerance, package dimensions, and compliance certifications, ensuring mechanical and electrical compatibility within their respective current and resistance specifications.

Frequently Asked Questions (FAQ)

Q: Can LQW18AN56NJ00D replace 744761156C in all applications?

A: Substitution is valid only when application current requirements do not exceed 360 mA. If the design requires the full 600 mA rating or lower DC resistance of 250mOhm, the 744761156C is the appropriate choice.

Q: Are the physical dimensions identical between these parts?

A: Both parts use the 0603 (1608 Metric) package. The 744761156C has seated height of 1.10mm maximum. The LQW18AN56NJ00D has seated height of 1.00mm maximum. Both fit standard 0603 footprints, though the Murata part is slightly lower profile.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8504.50.8000.

Q: What is the difference in Q factor between these inductors?

A: The LQW18AN56NJ00D has a Q factor of 38 @ 200MHz, compared to 32 @ 200MHz for the 744761156C. Higher Q factor indicates lower losses at the specified frequency.

Q: Which part has better high-frequency performance?

A: The LQW18AN56NJ00D has a self-resonant frequency of 2.4 GHz versus 1.9 GHz for the 744761156C, providing extended usable frequency range for high-frequency circuit applications.
