Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Inductance value: 10 nH with ±3% tolerance
• Package / Case: 0201 (0603 Metric) surface mount
• Physical dimensions: 0.024" L x 0.012" W (0.61mm x 0.31mm)
• Height - Seated (Max): 0.013" (0.33mm)

Allowable Variation Parameters:

• Current Rating: Substitute must meet or exceed 180 mA requirement
• DC Resistance (DCR): Substitute must not exceed 1.3 Ohm maximum
• Operating Temperature Range: Substitute must cover or exceed -40°C ~ 85°C
• Shielding: Shielded or unshielded configurations are acceptable based on circuit requirements
• Inductor Type: Thin film or thick film constructions are acceptable if electrical parameters are met

The LQP03TN10NH02D from Murata Electronics meets all mandatory matching parameters and provides enhanced electrical performance characteristics, making it a valid substitute for the obsolete CML0306-10N-HNH.

Parameter Comparison

Engineering Selection Recommendations

The LQP03TN10NH02D is the designated substitute for the obsolete CML0306-10N-HNH based on the following engineering criteria:

Product Status Alignment: The CML0306-10N-HNH is classified as obsolete, while the LQP03TN10NH02D maintains active product status with established supply chain availability (105,200 pieces in stock versus 759 pieces for the original part).

Compliance and Certification: Both components maintain RoHS compliance and REACH unaffected status. The substitute achieves ROHS3 compliance, meeting current regulatory requirements. Both components carry identical ECCN (EAR99) and HTSUS (8504.50.8000) classifications.

Electrical Performance: The substitute provides superior electrical characteristics with 250 mA current rating (39% higher than the 180 mA requirement), significantly lower DC resistance at 700 mOhm maximum (46% reduction from 1.3 Ohm), and extended operating temperature range of -55°C to 125°C (exceeding the -40°C to 85°C specification).

Physical Compatibility: Both components share identical 0201 (0603 Metric) package specifications with matching height and footprint dimensions, ensuring direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the LQP03TN10NH02D directly replace the CML0306-10N-HNH without PCB modifications?

A: Yes. Both components share identical 0201 (0603 Metric) package dimensions, height specifications, and surface mount footprints. No PCB layout changes are required for physical substitution.

Q: What is the primary difference between the shielded CML0306-10N-HNH and the unshielded LQP03TN10NH02D?

A: The main part features shielding to reduce electromagnetic interference, while the substitute is unshielded. Shielding selection depends on circuit-specific EMI requirements. The unshielded configuration typically offers lower cost and smaller parasitic effects in low-interference environments.

Q: Does the lower DC resistance of the substitute (700 mOhm vs. 1.3 Ohm) affect circuit performance?

A: The lower DC resistance of the LQP03TN10NH02D represents an improvement over the original specification. This reduction decreases resistive losses and heat generation, benefiting overall circuit efficiency. No negative performance impact is introduced by this parameter change.

Q: Are there any temperature range considerations when substituting?

A: The substitute operates across -55°C to 125°C, which exceeds the original -40°C to 85°C range. This extended temperature capability provides additional design margin and is fully compatible with the original specification requirements.

Q: What is the significance of the different inductor types (thin film vs. thick film)?

A: Both thin film and thick film inductors achieve the specified 10 nH inductance with ±3% tolerance. The thick film construction of the substitute provides the lower DC resistance characteristic while maintaining electrical performance equivalence at the specified inductance value and tolerance.

Q: Is the substitute available in the same packaging format?

A: Yes. The LQP03TN10NH02D is available in Cut Tape (CT) and Digi-Reel packaging formats, providing standard production-ready packaging options for manufacturing integration.
