Key Parameters

Substitute Part Grouping Explanation

Substitution of the CML0306-22N-HNH is determined by the following critical parameters:

Inductance Value: 22 nH is the primary electrical specification. Substitute parts must maintain this exact inductance with the specified ±3% tolerance.

Package Format: Both the main part and substitute must use the 0201 (0603 Metric) surface mount package to ensure physical compatibility with existing PCB layouts and assembly processes.

Current Rating: The substitute must support a minimum current rating equal to or exceeding the 120 mA requirement of the original component.

DC Resistance: The substitute's maximum DCR should not significantly exceed the original 2.55Ohm specification to maintain circuit performance characteristics.

Compliance Standards: RoHS compliance is required for regulatory adherence in target markets.

The LQP03TN22NH02D from Murata Electronics meets these substitution criteria while offering enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The LQP03TN22NH02D is an active product with current manufacturing support and improved availability compared to the obsolete CML0306-22N-HNH. Both components maintain RoHS compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility.

The substitute part provides superior electrical performance with lower DC resistance (1.9Ohm versus 2.55Ohm) and higher current rating capability (150 mA versus 120 mA). The extended operating temperature range (-55°C to 125°C) accommodates broader application requirements.

The primary design consideration is the shielding difference: the original part is shielded while the substitute is unshielded. This distinction affects electromagnetic interference characteristics and must be evaluated within the specific circuit context.

Frequently Asked Questions (FAQ)

Q: Can the LQP03TN22NH02D directly replace the CML0306-22N-HNH in existing designs?

A: Both components share identical inductance values (22 nH), tolerance (±3%), and package format (0201). Physical and electrical compatibility is established for these core parameters. The unshielded design of the substitute requires assessment of EMI performance in the target application.

Q: What is the impact of the shielding difference between these parts?

A: The CML0306-22N-HNH features shielding to reduce electromagnetic radiation and susceptibility. The LQP03TN22NH02D is unshielded. Applications sensitive to EMI or operating in electromagnetically noisy environments must evaluate whether the unshielded design affects circuit performance.

Q: Does the lower DC resistance of the substitute part affect circuit operation?

A: The LQP03TN22NH02D exhibits lower DC resistance (1.9Ohm maximum versus 2.55Ohm maximum). This reduction decreases resistive losses and heat generation, generally providing improved performance in current-carrying applications.

Q: Are both parts compatible with the same PCB assembly processes?

A: Yes. Both components use the 0201 (0603 Metric) surface mount package with identical physical dimensions (0.024" L x 0.012" W, height 0.013" maximum). Standard SMD assembly equipment and processes are compatible with both parts.

Q: What is the availability status of each part?

A: The CML0306-22N-HNH is obsolete with limited remaining inventory. The LQP03TN22NH02D is an active product with substantial inventory availability, ensuring long-term supply chain reliability.
