Key Parameters

Substitute Part Grouping Explanation

Substitution of the CML0306-12N-JNH is determined by the following critical parameters:

• Inductance Value: Must be 12 nH to maintain circuit function
• Package / Case: Must be 0201 (0603 Metric) for mechanical and electrical compatibility
• Current Rating: Substitute must support minimum 180 mA operation
• DC Resistance: Substitute must not exceed 1.3 Ohm maximum to preserve circuit performance
• Operating Temperature Range: Substitute must cover or exceed -40°C ~ 85°C
• Compliance: RoHS and REACH compliance status must be maintained

The LQP03HQ12NH02D from Murata Electronics meets these substitution criteria with equivalent inductance, package, and compliance specifications, while offering improved electrical characteristics in certain parameters.

Parameter Comparison

Engineering Selection Recommendations

The LQP03HQ12NH02D is a valid substitute for the obsolete CML0306-12N-JNH based on the following factors:

• Both components maintain identical 12 nH inductance value and 0201 (0603 Metric) package specification
• The substitute provides superior current rating capacity (300 mA vs. 180 mA), ensuring adequate margin for the original design requirement
• DC resistance of the substitute (500 mOhm) is significantly lower than the original specification (1.3 Ohm), improving circuit efficiency
• The substitute operates across an extended temperature range (-55°C ~ 125°C) that encompasses the original operating window (-40°C ~ 85°C)
• Both components maintain full RoHS and REACH compliance status
• The substitute is classified as active product status, ensuring long-term availability and supply chain continuity

The primary design consideration is the transition from shielded to unshielded construction. Circuit-level electromagnetic compatibility assessment is required to determine if unshielded operation is acceptable for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the LQP03HQ12NH02D directly replace the CML0306-12N-JNH without circuit modification?

A: Both components share identical inductance (12 nH) and package specifications (0201 / 0603 Metric), enabling direct mechanical and electrical substitution. The primary design consideration is the shielding difference: the original is shielded while the substitute is unshielded. Circuit-level electromagnetic compatibility must be evaluated for your specific application.

Q: What are the key differences between these two inductors?

A: The main differences are construction type (thin film vs. thick film), shielding (shielded vs. unshielded), DC resistance (1.3 Ohm vs. 500 mOhm), current rating (180 mA vs. 300 mA), and inductance tolerance (±5% vs. ±3%). The substitute offers lower resistance and higher current capacity.

Q: Why is the substitute unshielded while the original is shielded?

A: Shielding and construction type are design choices by the manufacturer. The thin film shielded construction of the original differs from the thick film unshielded design of the substitute. Application requirements determine whether shielding is necessary.

Q: Are both components RoHS compliant?

A: Yes. The original CML0306-12N-JNH is RoHS Compliant, and the substitute LQP03HQ12NH02D is ROHS3 Compliant. Both maintain REACH Unaffected status.

Q: What is the availability status of each component?

A: The CML0306-12N-JNH is classified as obsolete product status. The LQP03HQ12NH02D is classified as active product status, ensuring continued availability and supply chain support.
