CWL0306-6N2-JNH Equivalent & Substitute Parts

Part Overview

The CWL0306-6N2-JNH is a 6.2 nH shielded thin film inductor manufactured by Delta Electronics/Cyntec, designed for surface mount applications in the 0201 (0603 Metric) package. This component operates at 500 mA maximum current with a DC resistance of 220mOhm maximum and is rated for operating temperatures from -40°C to 125°C. The part is currently obsolete, making identification of suitable substitute components essential for ongoing production and maintenance applications requiring equivalent inductance and electrical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWL0306-6N2-JNH is determined by the following critical parameters:

• Inductance Value: Must be 6.2 nH to maintain circuit performance
• Package / Case: Must be 0201 (0603 Metric) for mechanical and electrical compatibility
• Current Rating: Substitute must support minimum 500 mA operation
• DC Resistance: Must not exceed 220mOhm to maintain acceptable losses
• Operating Temperature Range: Must cover the required -40°C to 125°C specification
• Self Resonant Frequency: Must be 5.5 GHz or higher to avoid resonance interference

The LQP03HQ6N2H02D from Murata Electronics meets the core inductance, package, and frequency requirements. However, differences in shielding type, current rating, DC resistance, and tolerance must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The LQP03HQ6N2H02D is an active product with current manufacturing support and ROHS3 compliance, providing supply chain continuity for the obsolete CWL0306-6N2-JNH. Both components share identical inductance values, self-resonant frequencies, package dimensions, and MSL ratings.

Substitution suitability depends on application-specific tolerances for the following deviations:

• Current Rating: The substitute supports 400 mA versus the original 500 mA specification. Applications requiring the full 500 mA rating cannot use this substitute.
• DC Resistance: The substitute exhibits 250mOhm maximum versus 220mOhm maximum, representing a 13.6% increase in maximum resistance.
• Shielding: The substitute is unshielded compared to the shielded original. Applications sensitive to electromagnetic interference or requiring shielding characteristics must evaluate this difference.
• Inductance Tolerance: The substitute offers ±3% tolerance versus ±5%, providing tighter inductance control.
• Operating Temperature: The substitute extends the lower temperature limit to -55°C, exceeding the original -40°C specification.

Frequently Asked Questions (FAQ)

Q: Can the LQP03HQ6N2H02D directly replace the CWL0306-6N2-JNH in all applications?

A: Direct replacement is not universal. The substitute meets core electrical specifications for inductance and frequency but has reduced current rating (400 mA vs. 500 mA), increased DC resistance (250mOhm vs. 220mOhm), and lacks shielding. Applications operating at or near 500 mA or requiring shielded performance must evaluate compatibility.

Q: What is the impact of the 50 mA current rating reduction?

A: The 100 mA reduction in maximum current rating (from 500 mA to 400 mA) affects thermal performance and saturation characteristics. Applications with current demands exceeding 400 mA cannot use this substitute without risk of component degradation or failure.

Q: Does the unshielded design of the substitute affect performance?

A: Unshielded inductors exhibit different electromagnetic field characteristics compared to shielded designs. Applications in high-frequency environments or those sensitive to crosstalk and EMI may experience performance differences. Circuit-level evaluation is necessary.

Q: Are the package dimensions identical between the two parts?

A: Yes. Both components use the 0201 (0603 Metric) package with identical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.017" (0.42mm), ensuring mechanical compatibility.

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

A: The substitute offers ±3% tolerance versus ±5% for the original. This tighter tolerance may benefit applications requiring precise inductance values but does not affect substitution eligibility for applications designed to the original ±5% specification.

Q: Are both parts RoHS compliant?

A: Yes. The original part is RoHS Compliant, and the substitute is ROHS3 Compliant. Both meet current environmental and regulatory requirements for electronic component manufacturing and use.
