Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CML0306-3N6-CNH is determined by the following critical parameters:

• Inductance value: 3.6 nH (exact match required)
• Current rating: 400 mA minimum
• Package / Case: 0201 (0603 Metric) surface mount
• Physical dimensions: Compatible with 0.024" L x 0.012" W footprint
• Operating temperature range: Must support application requirements
• DC resistance: Lower or equal values acceptable
• Self resonant frequency: 6GHz or higher acceptable

The LQP03TN3N6B02D from Murata Electronics meets these substitution criteria. While it differs in construction type (unshielded thick film versus shielded thin film), it maintains electrical equivalence in inductance, current rating, package format, and frequency characteristics.

Engineering Selection Recommendations

The LQP03TN3N6B02D is a direct functional substitute for the obsolete CML0306-3N6-CNH. Selection should be based on the following factors:

• Active product status: The LQP03TN3N6B02D is currently in active production with high inventory availability (95,200 pcs), ensuring long-term supply continuity.
• Compliance certifications: Both components meet RoHS and REACH requirements. The substitute carries ROHS3 compliance, meeting current regulatory standards.
• Electrical equivalence: Identical inductance value (3.6 nH), current rating (400 mA), and self resonant frequency (6GHz) ensure functional compatibility.
• Improved tolerance: The substitute offers tighter inductance tolerance (±0.1nH versus ±0.2nH), providing better circuit performance predictability.
• Lower DC resistance: The substitute's 300mOhm maximum DCR is lower than the main part's 320mOhm, reducing power dissipation.
• Extended temperature range: Operating range of -55°C to 125°C exceeds the main part's -40°C to 85°C specification.
• Shielding consideration: The substitute is unshielded while the main part is shielded. Circuit layout and EMI requirements must be evaluated for applications sensitive to electromagnetic coupling.

Frequently Asked Questions (FAQ)

Q: Can the LQP03TN3N6B02D directly replace the CML0306-3N6-CNH in all applications?

A: Electrical substitution is valid for inductance value, current rating, and frequency characteristics. However, the shielding difference requires circuit-level evaluation. If the original design relied on shielding to minimize EMI coupling, layout modifications or additional shielding measures may be necessary.

Q: What is the significance of the inductance tolerance difference?

A: The substitute's ±0.1nH tolerance is tighter than the main part's ±0.2nH tolerance. This provides better component consistency and improved circuit performance predictability, particularly in high-frequency applications where inductance precision affects impedance matching and signal integrity.

Q: Are the physical dimensions compatible?

A: Yes. Both components use the 0201 (0603 Metric) surface mount package with identical maximum height (0.013" / 0.33mm). Footprint dimensions are virtually identical (0.024" x 0.012"), ensuring PCB layout compatibility without modification.

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

A: Lower DC resistance (300mOhm versus 320mOhm) reduces resistive losses and power dissipation. This is a beneficial characteristic that improves efficiency and thermal performance without compromising circuit function.

Q: What compliance certifications apply to the substitute part?

A: The LQP03TN3N6B02D carries ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, meeting current regulatory and environmental standards for electronic components.

Q: Is the extended operating temperature range of the substitute a consideration?

A: The substitute's -55°C to 125°C range exceeds the main part's -40°C to 85°C specification. This provides additional operational margin for applications in extreme temperature environments, though it does not restrict use in standard temperature ranges.
