Key Parameters

Substitute Part Grouping Explanation

Substitution of the CML0510-12N-GNH is determined by the following critical parameters:

• Inductance Value: 12 nH (exact match required)
• Tolerance: ±2% (electrical specification match)
• Package / Case: 0402 (1005 Metric) (mechanical compatibility)
• Operating Temperature Range: -40°C ~ 125°C (thermal compatibility)
• Current Rating: Minimum 190 mA (functional requirement)
• DC Resistance: Maximum 1.8Ohm (electrical performance)

The Würth Elektronik 744901112 meets the core substitution criteria with matching inductance value, tolerance, package, and operating temperature range. Variations in secondary parameters such as shielding configuration and Q factor do not preclude substitution when the primary electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 744901112 is a direct functional substitute for the obsolete CML0510-12N-GNH. Both components share identical inductance values, tolerance specifications, package dimensions, and operating temperature ranges. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The 744901112 demonstrates superior electrical performance with lower DC resistance (1.6Ohm Max versus 1.8Ohm Max) and improved Q factor characteristics. The current rating of the substitute (180 mA) is marginally lower than the main part (190 mA); this difference must be evaluated against specific circuit requirements. Both components maintain full RoHS compliance and are suitable for equivalent thermal environments.

The primary design consideration is the shielding configuration difference: the main part is shielded while the substitute is unshielded. This distinction requires assessment based on electromagnetic interference (EMI) requirements of the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can the 744901112 be used as a direct replacement for the CML0510-12N-GNH?

A: The 744901112 meets the core electrical and mechanical specifications for substitution, including matching inductance (12 nH), tolerance (±2%), package (0402), and operating temperature range (-40°C to 125°C). The primary design consideration is the shielding difference; applications requiring shielded inductors must evaluate whether unshielded operation is acceptable.

Q: What is the significance of the current rating difference (190 mA vs. 180 mA)?

A: The substitute part has a 10 mA lower current rating. Circuit designs operating at or near the 190 mA specification of the original part require verification that the 180 mA rating of the substitute is sufficient for the intended application.

Q: Does the lower DC resistance of the substitute part affect compatibility?

A: Lower DC resistance (1.6Ohm Max versus 1.8Ohm Max) represents improved electrical performance and does not create compatibility issues. This characteristic is beneficial for applications sensitive to resistive losses.

Q: Are there packaging or mounting differences between these components?

A: Both components use identical 0402 (1005 Metric) surface mount packages with matching footprints and mounting requirements. No PCB layout modifications are necessary for substitution.

Q: What is the compliance status of both parts?

A: The main part is RoHS Compliant. The substitute part is ROHS3 Compliant, representing current regulatory compliance standards. Both parts are REACH Unaffected and classified under ECCN EAR99.
