CML0306-15N-JNH Equivalent & Substitute Parts

Part Overview

The CML0306-15N-JNH is a 15 nH shielded thin film inductor manufactured by Delta Electronics/Cyntec, designed for surface mount applications in the 0201 (0603 Metric) package. This component operates across -40°C to 85°C with a maximum DC resistance of 1.5Ohm and supports a 180 mA current rating. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CML0306-15N-JNH is determined by the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 15 nH
• Inductance tolerance: ±5%
• Package / Case: 0201 (0603 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 0.024" L x 0.012" W (0.61mm x 0.31mm)

Allowable Variation Parameters:

• Current rating must meet or exceed 180 mA
• DC resistance must not exceed 1.5Ohm
• Operating temperature range must encompass or extend the original -40°C ~ 85°C specification
• Shielding type (shielded or unshielded) may differ based on application requirements

The LQP03TN15NJ02D from Murata Electronics meets the mandatory matching criteria while providing enhanced electrical performance in current rating and DC resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The LQP03TN15NJ02D is an active product with current manufacturing support and ROHS3 compliance, providing supply chain continuity for applications currently using the obsolete CML0306-15N-JNH. Both components share identical inductance values, tolerances, and package specifications, ensuring mechanical and electrical compatibility at the circuit board level.

The substitute part delivers superior electrical performance with 250 mA current rating versus 180 mA and significantly lower DC resistance at 700mOhm maximum compared to 1.5Ohm maximum. The extended operating temperature range of -55°C to 125°C provides broader environmental coverage than the original -40°C to 85°C specification.

The primary design consideration is the transition from shielded to unshielded construction. Applications requiring electromagnetic shielding characteristics must evaluate the unshielded topology of the LQP03TN15NJ02D against specific circuit layout and interference requirements.

Frequently Asked Questions (FAQ)

Q: Can the LQP03TN15NJ02D directly replace the CML0306-15N-JNH in existing designs?

A: Direct mechanical and electrical replacement is supported for applications where the unshielded inductor topology is compatible with circuit design requirements. The identical 15 nH inductance, ±5% tolerance, and 0201 package ensure footprint and inductance value compatibility. Applications dependent on shielding characteristics require design review.

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

A: The primary differences are shielding type (shielded versus unshielded), DC resistance (1.5Ohm versus 700mOhm), current rating (180 mA versus 250 mA), and product status (obsolete versus active). Both share identical inductance values, tolerances, and package dimensions.

Q: Does the lower DC resistance of the LQP03TN15NJ02D affect circuit performance?

A: Lower DC resistance reduces power dissipation and heat generation in the inductor. For applications operating at or near the 180 mA current limit of the original part, the improved DCR characteristic of the substitute provides enhanced thermal performance and efficiency.

Q: Are there packaging or supply format differences?

A: The LQP03TN15NJ02D is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. Verify packaging compatibility with your procurement and assembly processes.

Q: What is the impact of the unshielded design on circuit layout?

A: Unshielded inductors exhibit greater magnetic field radiation compared to shielded designs. Circuit layouts with sensitive analog or RF components in close proximity require evaluation to ensure adequate spacing and isolation from the inductor's magnetic field.
