CML0510-2N2-CNH Equivalent & Substitute Parts

Part Overview

The CML0510-2N2-CNH is a 2.2 nH shielded thin film inductor manufactured by Delta Electronics/Cyntec in the CML0510 series. This surface mount component is rated for 730 mA continuous current with a maximum DC resistance of 140 mOhm and operates across the temperature range of -40°C to 125°C. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CML0510-2N2-CNH is determined by the following critical parameters:

• Inductance Value: Must be 2.2 nH to maintain circuit functionality
• Package / Case: Must be 0402 (1005 Metric) for mechanical and electrical compatibility
• Operating Temperature Range: Must support -40°C to 125°C minimum
• Current Rating: Must meet or exceed the application's current requirements
• DC Resistance: Lower DCR values are acceptable; higher values may impact circuit performance
• Compliance Standards: RoHS and REACH compliance ensure regulatory alignment

The Würth Elektronik 744901022 meets the core inductance and package requirements. However, differences in current rating, DC resistance, and shielding characteristics must be evaluated against specific application demands.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 744901022 is an active product with current manufacturing support, making it suitable for long-term procurement compared to the obsolete CML0510-2N2-CNH. Both components meet identical operating temperature requirements and possess equivalent moisture sensitivity ratings.

Selection of the 744901022 requires evaluation of the following trade-offs:

• Current Rating: The substitute is rated for 440 mA versus the original 730 mA. Applications requiring the full 730 mA rating cannot use this substitute.
• DC Resistance: The substitute exhibits 300 mOhm maximum DCR compared to 140 mOhm in the original. This increased resistance may introduce additional power dissipation in high-current applications.
• Shielding: The substitute is unshielded, whereas the original is shielded. Unshielded inductors may exhibit increased susceptibility to electromagnetic interference in sensitive RF or high-frequency circuits.

Both components are RoHS and REACH compliant, supporting regulatory requirements for modern electronics manufacturing.

Frequently Asked Questions (FAQ)

Q: Can the 744901022 be used as a direct replacement for the CML0510-2N2-CNH?

A: Direct substitution is possible only if the application current requirement does not exceed 440 mA and the circuit does not require shielding. The identical inductance value (2.2 nH) and package (0402) support mechanical and electrical compatibility. However, the increased DC resistance and unshielded design may affect circuit performance in specific applications.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The 744901022 has a maximum DCR of 300 mOhm compared to 140 mOhm in the original. This difference results in increased resistive losses, particularly in circuits carrying sustained current. Power dissipation increases proportionally with current squared (P = I²R), making this parameter critical in high-current or efficiency-sensitive designs.

Q: Does the unshielded design of the 744901022 affect circuit performance?

A: Unshielded inductors are more susceptible to electromagnetic coupling with nearby components and traces. In RF circuits, high-frequency switching applications, or densely populated PCBs, this may introduce unwanted coupling effects. Shielded inductors, such as the original CML0510-2N2-CNH, provide magnetic field containment to minimize these interactions.

Q: Are both parts compatible with the same PCB footprint?

A: Yes. Both components use the 0402 (1005 Metric) package with identical length and width dimensions (0.039" L x 0.020" W). The substitute has a slightly lower seated height (0.016" versus 0.020"), which does not affect PCB layout compatibility.

Q: What compliance certifications apply to both parts?

A: Both components are RoHS compliant and REACH unaffected, meeting current regulatory requirements for electronics manufacturing in regulated markets. The substitute carries ROHS3 certification, representing the latest RoHS directive compliance standard.
