Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CML0510-1N2-CNH is determined by the following critical parameters:

• Inductance value: 1.2 nH (tolerance variations acceptable within design margin)
• Package / Case: 0402 (1005 Metric) for mechanical and PCB compatibility
• DC Resistance: 100 mOhm Max (electrical performance requirement)
• Operating Temperature Range: -40°C to 125°C minimum
• RoHS and environmental compliance status

The Würth Elektronik 744901012 shares the same inductance value, package, DCR specification, and operating temperature range. However, the current rating differs (700 mA vs. 1.2 A) and shielding configuration differs (unshielded vs. shielded). These differences must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The 744901012 from Würth Elektronik (WE-TCI series) provides functional equivalence for inductance, package footprint, and thermal operating range. The part maintains RoHS3 compliance and unlimited moisture sensitivity rating, meeting environmental and regulatory requirements.

Selection between these parts depends on circuit-specific constraints:

Current rating differential: The CML0510-1N2-CNH supports 1.2 A while the 744901012 is rated for 700 mA. Applications requiring current levels between 700 mA and 1.2 A must evaluate thermal and reliability margins.

Shielding configuration: The CML0510-1N2-CNH is shielded while the 744901012 is unshielded. Shielded inductors reduce electromagnetic coupling to adjacent circuit elements. Unshielded alternatives may introduce crosstalk in sensitive RF or high-speed digital applications.

Physical height: The 744901012 has a lower seated height (0.016" vs. 0.020"), which may provide PCB layout advantages in space-constrained designs.

The 744901012 is currently in active production with established supply chain availability, whereas the CML0510-1N2-CNH is obsolete.

Frequently Asked Questions (FAQ)

Q: Can the 744901012 directly replace the CML0510-1N2-CNH in all applications?

A: Direct replacement requires verification of two factors: (1) circuit current requirements must not exceed 700 mA, and (2) the unshielded configuration must not introduce unacceptable electromagnetic coupling in the target application. Inductance value and package compatibility are equivalent.

Q: What is the significance of shielding in this inductor category?

A: Shielded inductors contain the magnetic field within the component, reducing interference with nearby circuits. Unshielded inductors have a larger external magnetic field. Selection depends on circuit layout density and sensitivity to magnetic coupling.

Q: Are there tolerance differences between these parts?

A: Yes. The CML0510-1N2-CNH specifies ±0.2 nH tolerance while the 744901012 specifies ±0.1 nH. The Würth part offers tighter tolerance control, which may be advantageous in precision RF or impedance-critical applications.

Q: Does the height difference affect PCB assembly?

A: The 744901012 is 0.004" (0.10mm) shorter when seated. This difference is negligible for most applications but may provide marginal benefits in ultra-compact designs. Standard pick-and-place equipment handles both heights without adjustment.

Q: Are both parts RoHS compliant?

A: Yes. The CML0510-1N2-CNH is RoHS Compliant and the 744901012 is ROHS3 Compliant. Both meet current environmental regulations for lead-free and restricted substance requirements.
