Key Parameters

Substitute Part Grouping Explanation

Substitution of the CML0306-4N7-HNH is determined by the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 4.7 nH
• Inductance tolerance: ±3%
• Package / Case: 0201 (0603 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 0.024" L x 0.012" W (0.61mm x 0.31mm)

Allowable Variation Parameters:

• Current rating: Substitute must meet or exceed 280 mA
• DC resistance: Substitute must not exceed 450mOhm
• Operating temperature: Substitute must cover or exceed -40°C ~ 85°C range
• Shielding: Shielded or unshielded configurations are acceptable based on circuit requirements
• RoHS compliance: Must maintain RoHS compliance status

The LQP03TN4N7H02D from Murata Electronics meets all mandatory matching parameters and exceeds performance specifications in current rating (350 mA vs. 280 mA) and DC resistance (400mOhm vs. 450mOhm maximum).

Parameter Comparison

Engineering Selection Recommendations

The LQP03TN4N7H02D is a direct functional substitute for the obsolete CML0306-4N7-HNH. The substitute component provides superior electrical performance with higher current rating (350 mA vs. 280 mA) and lower DC resistance (400mOhm vs. 450mOhm maximum), ensuring compatibility with existing circuit designs.

Key considerations for selection:

Shielding Difference: The main part is shielded while the substitute is unshielded. In applications where electromagnetic shielding is critical to circuit performance, this difference must be evaluated against specific circuit requirements and EMI/RFI specifications.

Temperature Range: The substitute operates across -55°C to 125°C, exceeding the original -40°C to 85°C range, providing broader operational capability.

Compliance: Both components maintain RoHS compliance. The substitute carries ROHS3 certification, meeting current regulatory requirements. Both are REACH Unaffected and classified as EAR99.

Availability: The substitute is in active production status with substantial inventory availability (95,300 pcs), ensuring long-term supply continuity compared to the obsolete original component.

Frequently Asked Questions (FAQ)

Q: Can the LQP03TN4N7H02D directly replace the CML0306-4N7-HNH in existing designs?

A: Yes, the LQP03TN4N7H02D meets all mandatory electrical and mechanical specifications. The primary design consideration is the shielding difference. If the original design does not depend on shielding for EMI control, direct substitution is valid. If shielding is required, circuit-level evaluation is necessary.

Q: What is the impact of the unshielded configuration of the substitute?

A: The unshielded design of the LQP03TN4N7H02D may result in increased electromagnetic coupling to surrounding circuit elements compared to the shielded original. This is relevant only in applications with strict EMI/RFI requirements or high-frequency sensitive circuits. Standard RF and mixed-signal applications typically tolerate this difference.

Q: Are the physical dimensions identical?

A: Yes. Both components use the 0201 (0603 Metric) package with identical footprints: 0.024" L x 0.012" W (0.61mm x 0.31mm) and 0.013" maximum seated height (0.33mm). PCB layout and assembly processes require no modification.

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

A: The lower DC resistance (400mOhm vs. 450mOhm maximum) of the substitute is beneficial, reducing resistive losses and heat generation. This represents an improvement over the original specification.

Q: What is the significance of the higher current rating of the substitute?

A: The LQP03TN4N7H02D is rated for 350 mA versus 280 mA for the original. This provides additional design margin and allows the component to operate at higher current levels without saturation, improving reliability in current-limited applications.

Q: Are there packaging or supply format differences?

A: The substitute is supplied in Cut Tape (CT) and Digi-Reel® formats. Confirm packaging compatibility with your procurement and assembly processes.
