Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 744761087C are qualified based on the following critical parameters:

• Inductance value of 8.7 nH (tolerance variations within ±5% or tighter are acceptable)
• Current rating of 700 mA or higher
• DC resistance not exceeding 100mOhm (or within acceptable operational limits)
• Surface mount package 0603 (1608 Metric)
• Unshielded configuration
• Operating temperature range of -40°C to 125°C or wider
• ROHS3 compliance

The identified substitutes maintain these core electrical and mechanical specifications, ensuring functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three inductors meet the core substitution criteria for the 744761087C application. Selection between them depends on specific circuit requirements:

The TE Connectivity 36501J8N7JTDG maintains identical current rating (700 mA) and operating temperature range. DC resistance increases by 10 mOhm, which remains within acceptable operational margins for most applications. This part carries AEC-Q200 automotive qualification.

The Murata LQW18AN8N7D00D offers superior inductance tolerance (±0.5nH versus ±5%) and higher Q factor (35 versus 28 at 250MHz), providing better frequency stability and lower losses. Current rating is 650 mA, which is acceptable for applications not requiring the full 700 mA specification. Operating temperature range extends to -55°C, providing wider environmental coverage. DC resistance matches the TE Connectivity part at 110 mOhm maximum.

All substitutes are ROHS3 compliant with MSL rating 1, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 36501J8N7JTDG replace the Würth 744761087C directly?

A: Yes. Both parts share identical inductance (8.7 nH), current rating (700 mA), package (0603), and operating temperature range (-40°C to 125°C). DC resistance increases from 100 mOhm to 110 mOhm, which is acceptable for most circuit applications.

Q: What is the limitation of the Murata LQW18AN8N7D00D as a substitute?

A: The Murata part has a current rating of 650 mA compared to the original 700 mA specification. This substitute is suitable only for applications where the circuit current does not exceed 650 mA. All other electrical and mechanical parameters are compatible.

Q: Are all three parts pin-compatible?

A: Yes. All three inductors use the 0603 (1608 Metric) surface mount package with identical footprint and mounting requirements.

Q: Which substitute offers the best frequency stability?

A: The Murata LQW18AN8N7D00D provides the highest Q factor (35 at 250MHz) and tightest inductance tolerance (±0.5nH), resulting in superior frequency stability and lower insertion loss compared to the other options.

Q: Do all substitutes meet environmental compliance requirements?

A: Yes. All three parts are ROHS3 compliant with MSL rating 1 (Unlimited), meeting standard environmental and moisture sensitivity requirements for surface mount assembly.
