Key Parameters

Substitute Part Grouping Explanation

Substitution of the CML0306-2N4-SNH is determined by the following critical parameters:

• Inductance Value: 2.4 nH (primary electrical specification)
• Current Rating: 500 mA minimum
• DC Resistance: 200 mOhm maximum
• Package / Case: 0201 (0603 Metric) surface mount
• Operating Temperature Range: Must support minimum -40°C to 85°C
• Compliance: RoHS and REACH compliance status

The LQP03TN2N4B02D from Murata Electronics meets these core electrical and mechanical requirements. While this substitute employs unshielded thick film construction versus the original shielded thin film design, both components deliver identical inductance, current rating, and DC resistance specifications within the same physical package footprint.

Parameter Comparison

Engineering Selection Recommendations

The LQP03TN2N4B02D is an active production component from Murata Electronics with superior availability (20,300 units in stock versus 954 units for the obsolete CML0306-2N4-SNH). Both parts satisfy identical electrical specifications for inductance, current rating, and DC resistance. The substitute provides an extended operating temperature range (-55°C to 125°C versus -40°C to 85°C) and tighter inductance tolerance (±0.1 nH versus ±0.3 nH), representing improved performance margins.

The primary design consideration is the transition from shielded to unshielded construction. Applications requiring electromagnetic shielding for noise isolation must evaluate circuit-level implications. Both components maintain full RoHS and REACH compliance, supporting regulatory requirements for current production environments.

Frequently Asked Questions (FAQ)

Q: Can the LQP03TN2N4B02D directly replace the CML0306-2N4-SNH in all applications?

A: Both components share identical inductance (2.4 nH), current rating (500 mA), DC resistance (200 mOhm), and physical package (0201 / 0603 Metric). The primary difference is shielding: the original is shielded while the substitute is unshielded. Applications sensitive to electromagnetic interference must evaluate circuit-level performance.

Q: What is the impact of the shielded versus unshielded construction?

A: Shielded inductors provide electromagnetic containment, reducing radiated emissions and susceptibility to external fields. Unshielded inductors occupy less board space and typically exhibit lower parasitic capacitance. Circuit performance depends on proximity to sensitive components and overall EMI environment.

Q: Are there temperature range differences between these parts?

A: Yes. The CML0306-2N4-SNH operates from -40°C to 85°C, while the LQP03TN2N4B02D operates from -55°C to 125°C. The substitute provides extended temperature coverage, beneficial for applications requiring broader thermal performance.

Q: How do inductance tolerances compare?

A: The original part specifies ±0.3 nH tolerance, while the substitute offers ±0.1 nH tolerance. The tighter tolerance of the substitute reduces inductance variation across production batches, improving circuit consistency.

Q: Are both parts RoHS compliant?

A: Yes. The CML0306-2N4-SNH is RoHS Compliant, and the LQP03TN2N4B02D is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What is the availability status of each part?

A: The CML0306-2N4-SNH is obsolete with limited remaining inventory (954 units). The LQP03TN2N4B02D is in active production with significantly higher availability (20,300 units), supporting long-term supply chain continuity.
