CML0510-1N5-CNH Equivalent & Substitute Parts

Part Overview

The CML0510-1N5-CNH is a 1.5 nH shielded thin film inductor manufactured by Delta Electronics/Cyntec, rated for 1.2 A maximum current with 100mOhm DC resistance. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The part operates across the -40°C to 125°C temperature range and is RoHS compliant with unlimited moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CML0510-1N5-CNH is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 1.5 nH (exact match required)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Operating temperature range: -40°C ~ 125°C (minimum requirement)

Secondary Compatibility Factors:

• Current rating must meet or exceed application requirements
• DC resistance must be acceptable for circuit performance
• Shielding characteristics may differ based on EMI requirements
• Tolerance specifications must support circuit design margins

The substitute part 744901015 (Würth Elektronik WE-TCI series) matches the primary criteria with identical inductance and package specifications. However, differences exist in current rating, DC resistance, and shielding configuration that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 744901015 (Würth Elektronik WE-TCI) is an active product with current RoHS3 compliance, providing long-term availability and supply chain stability compared to the obsolete CML0510-1N5-CNH. Both components share identical inductance values, package specifications, and operating temperature ranges.

Selection between these parts depends on application-specific current and resistance requirements:

• Use 744901015 when: Circuit current requirements do not exceed 700 mA and the additional DC resistance (200mOhm vs 100mOhm) is acceptable for circuit performance. The unshielded configuration is suitable for applications without strict EMI isolation requirements.

• Use CML0510-1N5-CNH when: Applications require the full 1.2 A current rating and shielded construction is mandatory for EMI performance. Availability is limited due to obsolete status.

Both components meet unlimited moisture sensitivity requirements and are REACH unaffected, supporting compliance with environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can 744901015 directly replace CML0510-1N5-CNH in all applications?

A: Direct replacement is possible only when circuit current requirements do not exceed 700 mA and the increased DC resistance (200mOhm vs 100mOhm) does not degrade circuit performance. The unshielded design of 744901015 may require evaluation if EMI shielding is critical to application function.

Q: What is the impact of the different DC resistance values?

A: The CML0510-1N5-CNH specifies 100mOhm maximum DC resistance, while 744901015 specifies 200mOhm maximum. This 2x difference affects power dissipation and insertion loss. Applications sensitive to these parameters must verify compatibility through circuit simulation or testing.

Q: Why does the substitute part have lower current rating?

A: The 744901015 is rated for 700 mA maximum current compared to 1.2 A for the CML0510-1N5-CNH. Applications requiring currents above 700 mA cannot use the substitute without risk of component degradation or failure.

Q: Are the shielding differences significant?

A: The CML0510-1N5-CNH is shielded while 744901015 is unshielded. Shielding reduces electromagnetic coupling to adjacent components and traces. Applications in high-density layouts or sensitive RF environments may require the shielded configuration.

Q: Do both parts have the same package footprint?

A: Yes. Both components use the 0402 (1005 Metric) package with identical length (0.039" / 1.00mm) and width (0.020" / 0.50mm). Height differs slightly (0.50mm vs 0.40mm seated), which is negligible for most PCB assembly processes.

Q: What is the difference in inductance tolerance?

A: The 744901015 offers tighter tolerance (±0.1nH) compared to CML0510-1N5-CNH (±0.2nH). This provides better inductance consistency for precision circuit applications.
