Key Parameters

Substitute Part Grouping Explanation

Substitution for the 744761056C is determined by the following critical parameters:

• Inductance Value: 5.6 nH (tolerance range must accommodate ±5% specification)
• Current Rating: Minimum 700 mA continuous current capability
• DC Resistance: Maximum 190mOhm at rated current
• Package: 0603 (1608 Metric) surface mount only
• Core Type: Drum core wirewound construction
• Shielding: Unshielded configuration
• Compliance: ROHS3 and REACH requirements

The Murata Electronics LQW18AN5N6D00D meets these substitution criteria with equivalent inductance, superior current rating (750 mA), lower DC resistance (82mOhm), and identical package geometry and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The Murata LQW18AN5N6D00D is a direct substitute for the Würth 744761056C in applications requiring 5.6 nH inductance in 0603 surface mount package. Both parts maintain ROHS3 and REACH compliance. The Murata part provides enhanced electrical performance with lower DC resistance (82mOhm vs. 190mOhm), higher current rating (750 mA vs. 700 mA), and superior Q factor (35 vs. 16 at 250 MHz). The Murata part also extends the operating temperature range to -55°C, providing additional margin for extreme environment applications. Mechanical compatibility is confirmed through identical package dimensions and surface mount configuration.

Frequently Asked Questions (FAQ)

Q: Can the Murata LQW18AN5N6D00D replace the Würth 744761056C in existing designs?

A: Yes. Both parts are 5.6 nH inductors in 0603 (1608 Metric) surface mount package with unshielded drum core construction. Electrical parameters are compatible, with the Murata part offering superior performance margins in current rating and DC resistance.

Q: What are the key differences between these two parts?

A: The primary differences are DC resistance (Murata 82mOhm vs. Würth 190mOhm), current rating (Murata 750 mA vs. Würth 700 mA), Q factor at 250 MHz (Murata 35 vs. Würth 16), and operating temperature range (Murata -55°C to 125°C vs. Würth -40°C to 125°C). Inductance value and package are identical.

Q: Are there any mechanical compatibility concerns?

A: No. Both parts use identical 0603 (1608 Metric) package with surface mount configuration. Physical dimensions are compatible with standard PCB footprints designed for this package class.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the Würth 744761056C and Murata LQW18AN5N6D00D are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For designs requiring maximum performance margin and extended temperature range, the Murata LQW18AN5N6D00D is preferred. For cost-sensitive applications where the Würth part specifications are sufficient, either part is acceptable based on availability and procurement terms.
