Key Parameters

Substitute Part Grouping Explanation

Substitution of the CML0306-10N-JNH is determined by the following critical parameters:

• Inductance Value: 10 nH (with ±5% tolerance)
• Package / Case: 0201 (0603 Metric) surface mount
• Physical Dimensions: 0.024" L x 0.012" W (0.61mm x 0.31mm)
• Current Rating: Minimum 180 mA
• DC Resistance: Acceptable range based on circuit requirements
• Operating Temperature Range: Must support -40°C ~ 85°C minimum
• Compliance: RoHS and REACH compliance status

The LQP03TN10NJ02D from Murata Electronics meets the core electrical and mechanical requirements for substitution, sharing identical inductance value, tolerance, package type, and physical dimensions. Both components are RoHS and REACH compliant.

Parameter Comparison

Engineering Selection Recommendations

The LQP03TN10NJ02D is an active product with current manufacturing support and improved availability (50,599 pieces in stock versus 968 pieces for the obsolete CML0306-10N-JNH). Both components maintain RoHS and REACH compliance, ensuring regulatory alignment.

Key considerations for selection:

• Current Capacity: The LQP03TN10NJ02D provides 250 mA rating, exceeding the 180 mA requirement of the original design.
• DC Resistance: The substitute exhibits lower DC resistance (700 mOhm versus 1.3 Ohm), which may reduce power dissipation in the circuit.
• Shielding: The original component is shielded while the substitute is unshielded. In applications requiring electromagnetic isolation, shielding characteristics must be evaluated against circuit layout and noise immunity requirements.
• Temperature Range: The substitute supports an extended operating temperature range (-55°C ~ 125°C), providing greater thermal margin than the original (-40°C ~ 85°C).
• Package Compatibility: Both components use identical 0201 (0603 Metric) packages with matching physical dimensions and mounting characteristics, ensuring direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the LQP03TN10NJ02D directly replace the CML0306-10N-JNH on existing PCBs?

A: Yes, from a mechanical and electrical standpoint. Both components share the same 0201 (0603 Metric) package, identical physical dimensions, and 10 nH inductance value with ±5% tolerance. PCB footprints are compatible without modification.

Q: What is the impact of the shielding difference between the two components?

A: The CML0306-10N-JNH is shielded while the LQP03TN10NJ02D is unshielded. Shielding reduces electromagnetic coupling to surrounding circuit elements. In applications sensitive to EMI or requiring isolation from adjacent components, the unshielded substitute may exhibit different performance characteristics. Circuit-level evaluation is necessary to determine if shielding is functionally required.

Q: How does the lower DC resistance of the substitute affect circuit performance?

A: The LQP03TN10NJ02D exhibits 700 mOhm maximum DC resistance compared to 1.3 Ohm for the original. Lower resistance reduces resistive losses and heat generation at the specified current levels. This generally improves efficiency but may alter impedance characteristics in high-frequency applications.

Q: Are both components compliant with current regulatory standards?

A: Yes. The CML0306-10N-JNH is RoHS Compliant and REACH Unaffected. The LQP03TN10NJ02D is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Q: What is the availability status of each component?

A: The CML0306-10N-JNH is obsolete with limited stock (968 pieces). The LQP03TN10NJ02D is an active product with substantial availability (50,599 pieces), ensuring long-term supply chain continuity.
