Key Parameters

Substitute Part Grouping Explanation

Substitution of the CML0306-5N1-JNH is determined by the following critical parameters:

• Inductance Value: Must be 5.1 nH to maintain circuit performance
• Package / Case: Must be 0201 (0603 Metric) for mechanical and electrical compatibility
• Current Rating: Substitute must support minimum 270 mA operation
• DC Resistance: Substitute maximum DCR must not exceed 500mOhm to prevent excessive power dissipation
• Operating Temperature: Substitute must cover the required temperature range
• Mounting Type: Must be Surface Mount for PCB assembly compatibility

The LQP03TN5N1H02D from Murata Electronics meets these substitution criteria with identical inductance value, package specification, and surface mount configuration. While the substitute offers enhanced performance characteristics (higher current rating, lower DCR, tighter tolerance), it remains functionally compatible within the electrical and mechanical constraints of the original design.

Parameter Comparison

Engineering Selection Recommendations

The LQP03TN5N1H02D is the designated substitute for the obsolete CML0306-5N1-JNH based on matching inductance specification, package form factor, and surface mount configuration. The substitute maintains RoHS and REACH compliance status equivalent to the original component. The LQP03TN5N1H02D is currently in active production with substantial inventory availability (20,100 pcs), ensuring supply chain continuity.

The substitute demonstrates improved electrical performance through lower DC resistance (400mOhm vs. 500mOhm maximum) and higher current rating capability (350 mA vs. 270 mA), providing design margin for existing applications. The extended operating temperature range (-55°C to 125°C) accommodates broader environmental requirements. The tighter inductance tolerance (±3% vs. ±5%) enhances circuit precision.

Design consideration: The LQP03TN5N1H02D is unshielded, whereas the original CML0306-5N1-JNH is shielded. Applications requiring electromagnetic shielding characteristics must evaluate this difference within their specific circuit context.

Frequently Asked Questions (FAQ)

Q: Can the LQP03TN5N1H02D directly replace the CML0306-5N1-JNH in existing designs?

A: Yes, for applications where shielding is not a critical design requirement. Both components share identical inductance value (5.1 nH), package specification (0201 / 0603 Metric), and surface mount configuration. The substitute exceeds the original current rating and DC resistance specifications, providing operational compatibility.

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

A: The original CML0306-5N1-JNH is shielded, while the LQP03TN5N1H02D is unshielded. Shielding reduces electromagnetic radiation and susceptibility to external interference. Applications sensitive to EMI/RFI performance must evaluate whether unshielded operation is acceptable within their circuit design.

Q: Are there compliance differences between the main part and substitute?

A: Both components are RoHS compliant and REACH unaffected. The substitute carries ROHS3 certification, representing current regulatory compliance. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the package compatibility between these inductors?

A: Both the CML0306-5N1-JNH and LQP03TN5N1H02D use the 0201 (0603 Metric) package with identical footprint dimensions (0.024" L x 0.012" W / 0.61mm x 0.30mm) and maximum seated height (0.013" / 0.33mm). PCB layout and assembly processes require no modification.

Q: How do the electrical performance characteristics compare?

A: The LQP03TN5N1H02D provides superior electrical performance: lower maximum DC resistance (400mOhm vs. 500mOhm), higher current rating (350 mA vs. 270 mA), and tighter inductance tolerance (±3% vs. ±5%). These improvements reduce power dissipation and enhance circuit precision without compromising compatibility.

Q: Is the extended temperature range of the substitute beneficial?

A: The LQP03TN5N1H02D operates across -55°C to 125°C compared to the original -40°C to 85°C range. This extended range provides design margin for applications operating in extreme thermal environments, though it is not required for designs already qualified to the original temperature specification.
