Key Parameters

Substitute Part Grouping Explanation

Substitution of the CML0306-3N0-SNH is determined by the following critical parameters:

• Inductance Value: 3 nH (tolerance ±0.3 nH for the main part)
• Current Rating: 450 mA minimum
• Package / Case: 0201 (0603 Metric) surface mount
• Operating Temperature Range: Must support -40°C to 85°C minimum
• DC Resistance: Lower or equal values are acceptable
• Regulatory Compliance: RoHS and REACH compliance required

The substitute part LQP03TN3N0B02D from Murata Electronics meets these core electrical and mechanical requirements. While this substitute differs in shielding type (unshielded versus shielded) and inductance tolerance (±0.1 nH versus ±0.3 nH), it maintains electrical equivalence for the specified inductance value, current rating, and package form factor. The substitute operates across an extended temperature range (-55°C to 125°C) and features improved DC resistance (250 mOhm maximum versus 300 mOhm maximum).

Parameter Comparison

Engineering Selection Recommendations

The LQP03TN3N0B02D is an active product with current manufacturing support and improved regulatory compliance (ROHS3 versus RoHS). This substitute maintains the critical electrical specifications: 3 nH inductance, 450 mA current rating, and 0201 package form factor. The substitute offers superior DC resistance performance (250 mOhm maximum) and tighter inductance tolerance (±0.1 nH), along with an extended operating temperature range that exceeds the original part's specifications.

Selection of this substitute is supported by product availability, active manufacturing status, and full regulatory compliance. The extended temperature range provides additional operational margin for applications requiring thermal robustness.

Frequently Asked Questions (FAQ)

Q: Can the LQP03TN3N0B02D directly replace the CML0306-3N0-SNH in all applications?

A: The substitute maintains electrical equivalence for inductance value (3 nH), current rating (450 mA), and package form factor (0201). The primary difference is shielding type: the original part is shielded while the substitute is unshielded. Applications sensitive to electromagnetic coupling or requiring shielding characteristics must evaluate this difference against specific circuit requirements.

Q: What is the impact of the inductance tolerance difference?

A: The substitute features tighter inductance tolerance (±0.1 nH versus ±0.3 nH), which provides improved consistency and reduced variation across production batches. This is a performance advantage for precision circuit applications.

Q: Are there temperature range considerations for substitution?

A: The substitute operates across -55°C to 125°C, which exceeds the original part's -40°C to 85°C range. This extended range is compatible with the original specification and provides additional operational margin.

Q: How do the DC resistance values affect substitution?

A: The substitute features lower maximum DC resistance (250 mOhm versus 300 mOhm), which reduces resistive losses and improves efficiency. This is a performance improvement over the original part.

Q: What packaging formats are available for the substitute?

A: The LQP03TN3N0B02D is supplied in Cut Tape (CT) and Digi-Reel® packaging, both compatible with standard surface mount assembly processes.
