Substitute Part Grouping Explanation

Substitution of the CML0306-8N2-HNH is determined by the following critical parameters:

• Inductance Value: Must be 8.2 nH with ±3% tolerance to maintain circuit performance
• Package Format: Must be 0201 (0603 Metric) for mechanical and electrical compatibility
• Current Rating: Substitute must support minimum 180 mA operation
• DC Resistance: Substitute DCR must not exceed application requirements
• Operating Temperature Range: Must encompass or exceed -40°C to 85°C
• RoHS Compliance: Must maintain RoHS compliance status for regulatory alignment

The identified substitute LQP03HQ8N2H02D from Murata Electronics meets the core inductance, tolerance, package, and compliance requirements. While differences exist in shielding type, current rating, and DCR specifications, these variations are within acceptable engineering parameters for equivalent substitution.

Parameter Comparison

Engineering Selection Recommendations

The LQP03HQ8N2H02D is an active, production-available substitute for the obsolete CML0306-8N2-HNH. Both components maintain identical inductance values and tolerances, identical package formats, and equivalent moisture sensitivity ratings. The substitute offers superior current handling capability (300 mA versus 180 mA) and an extended operating temperature range (-55°C to 125°C versus -40°C to 85°C), providing design margin for thermal and electrical stress conditions.

The substitute maintains full RoHS3 compliance, meeting current regulatory requirements. The primary design consideration is the transition from shielded to unshielded construction and the reduction in DC resistance (400mOhm versus 1.2Ohm maximum). These differences must be evaluated within the specific circuit application to determine compatibility with electromagnetic interference requirements and power dissipation constraints.

Frequently Asked Questions (FAQ)

Q: Can the LQP03HQ8N2H02D directly replace the CML0306-8N2-HNH in all applications?

A: Both components share identical inductance values, tolerances, and 0201 package specifications. However, the transition from shielded to unshielded construction and the difference in DC resistance require circuit-level evaluation. Applications sensitive to electromagnetic coupling or with strict power dissipation budgets must assess compatibility.

Q: What is the significance of the shielding difference?

A: The CML0306-8N2-HNH features shielded construction, which reduces electromagnetic radiation and susceptibility to external fields. The LQP03HQ8N2H02D is unshielded. In high-density layouts or noise-sensitive circuits, this difference may impact performance. In applications where shielding is not critical, the unshielded substitute is functionally equivalent.

Q: Does the lower DC resistance of the substitute provide an advantage?

A: The LQP03HQ8N2H02D exhibits 400mOhm maximum DCR compared to 1.2Ohm maximum for the original part. Lower DCR reduces resistive losses and heat generation, providing improved efficiency. This is advantageous in power-sensitive applications.

Q: Are both components available in the same packaging format?

A: Yes. Both the CML0306-8N2-HNH and LQP03HQ8N2H02D are supplied in 0201 (0603 Metric) package format with identical mechanical dimensions, ensuring compatibility with existing PCB layouts and assembly processes.

Q: What compliance certifications apply to the substitute?

A: The LQP03HQ8N2H02D maintains ROHS3 compliance and REACH unaffected status, equivalent to the original part's RoHS compliance. Both components carry EAR99 ECCN classification and identical HTSUS codes.
