Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CML0306-3N3-BNH is determined by the following critical parameters:

• Inductance Value: 3.3 nH with ±0.1 nH tolerance
• Current Rating: Minimum 450 mA
• Package / Case: 0201 (0603 Metric) surface mount
• Physical Dimensions: 0.024" L x 0.012" W with maximum seated height of 0.013"
• Operating Temperature Range: Must support -40°C minimum
• Regulatory Compliance: RoHS and REACH compliance required

The LQP03TN3N3B02D from Murata Electronics meets all critical substitution criteria. While this substitute features unshielded construction (versus the original shielded design) and improved DC resistance (250 mOhm versus 300 mOhm), it maintains electrical equivalence in inductance value, current rating, package format, and physical dimensions. The substitute offers an extended operating temperature range (-55°C to 125°C) and active product status, providing superior long-term availability.

Parameter Comparison

Engineering Selection Recommendations

The LQP03TN3N3B02D is the qualified substitute for the obsolete CML0306-3N3-BNH. Selection is based on:

• Regulatory Compliance: Both components maintain RoHS and REACH compliance. The substitute carries ROHS3 certification, meeting current regulatory requirements.
• Product Availability: The original component is obsolete with limited inventory (743 pcs). The substitute is active with substantial stock availability (78,794 pcs), ensuring production continuity.
• Electrical Equivalence: Identical inductance value (3.3 nH) and current rating (450 mA) with matching package and physical dimensions enable direct board-level substitution.
• Performance Enhancement: The substitute provides lower DC resistance (250 mOhm versus 300 mOhm) and extended operating temperature range (-55°C to 125°C versus -40°C to 85°C).

Frequently Asked Questions (FAQ)

Q: Can the LQP03TN3N3B02D replace the CML0306-3N3-BNH in existing designs?

A: Yes. Both components share identical inductance values (3.3 nH), current ratings (450 mA), package formats (0201/0603 Metric), and physical dimensions. The substitute is electrically and mechanically compatible for direct substitution.

Q: What is the difference between shielded and unshielded construction?

A: The original CML0306-3N3-BNH features shielded construction, while the LQP03TN3N3B02D is unshielded. Shielding reduces electromagnetic interference coupling to adjacent components. Unshielded designs occupy less board space and typically exhibit lower DC resistance. Application requirements determine whether shielding is necessary.

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

A: The substitute's lower DC resistance (250 mOhm versus 300 mOhm) represents an improvement. This reduces resistive losses and heat generation at rated current levels, benefiting overall circuit efficiency.

Q: Are there inventory or lead time advantages to using the substitute?

A: Yes. The original component is obsolete with limited stock (743 pcs). The substitute is an active product with 78,794 pcs in inventory, providing superior availability and shorter lead times for production requirements.

Q: Do both components meet current regulatory standards?

A: Yes. Both components are RoHS and REACH compliant. The substitute carries ROHS3 certification, confirming compliance with the latest regulatory requirements.
