CML0510-3N0-CNH Equivalent & Substitute Parts

Part Overview

The CML0510-3N0-CNH is a 3 nH shielded thin film inductor manufactured by Delta Electronics/Cyntec, designed for surface mount applications in the 0402 (1005 Metric) package. This component is rated for 570 mA continuous current with a maximum DC resistance of 200 mOhm and operates across the temperature range of -40°C to 125°C. The part is currently listed as obsolete, necessitating identification of functionally equivalent alternatives to maintain design continuity and ensure supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CML0510-3N0-CNH is determined by the following critical parameters:

Mandatory Matching Criteria:

• Inductance value: 3 nH (exact match required)
• Package / Case: 0402 (1005 Metric) (physical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)

Allowable Variation Parameters:

• Current Rating: Substitute must meet or exceed 570 mA requirement
• DC Resistance (DCR): Substitute must not exceed 200 mOhm Max
• Operating Temperature Range: Substitute must cover or exceed -40°C to 125°C
• Shielding: Shielded or unshielded acceptable based on circuit requirements
• RoHS / REACH Compliance: Must maintain regulatory compliance status

The ATFC-0402-3N0B-T from Abracon LLC meets the mandatory inductance and package criteria. However, this substitute exhibits reduced current rating (380 mA vs. 570 mA) and increased DC resistance (450 mOhm vs. 200 mOhm), representing a trade-off in electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ATFC-0402-3N0B-T is the identified equivalent substitute for the obsolete CML0510-3N0-CNH. Both components share identical inductance values (3 nH) and package specifications (0402 / 1005 Metric), enabling direct physical replacement in surface mount assemblies.

The substitute part carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. However, design validation is required in applications where the following performance differences are critical:

• Current rating reduction from 570 mA to 380 mA
• DC resistance increase from 200 mOhm to 450 mOhm
• Operating temperature upper limit reduction from 125°C to 85°C
• Shielding change from shielded to unshielded configuration

Applications operating within the ATFC-0402-3N0B-T electrical and thermal specifications may proceed with direct substitution. Applications requiring the full 570 mA current capacity, lower DC resistance, or extended temperature operation to 125°C require alternative component evaluation or circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the ATFC-0402-3N0B-T directly replace the CML0510-3N0-CNH in all applications?

A: Direct physical replacement is possible due to identical package specifications (0402 / 1005 Metric) and inductance values (3 nH). However, electrical performance differs. Applications must operate within the substitute's current rating (380 mA maximum) and temperature range (-45°C to 85°C). If the original design requires 570 mA current capacity or operation above 85°C, alternative components must be evaluated.

Q: What is the impact of the shielding difference?

A: The CML0510-3N0-CNH is shielded; the ATFC-0402-3N0B-T is unshielded. Shielding reduces electromagnetic interference coupling to adjacent circuit elements. In noise-sensitive applications, the unshielded substitute may introduce additional EMI considerations. Circuit layout and filtering requirements should be reviewed.

Q: How does the increased DC resistance affect circuit performance?

A: The substitute exhibits 450 mOhm maximum DC resistance compared to 200 mOhm in the original part. This 2.25× increase results in higher resistive losses and heat dissipation at rated current levels. Power loss increases proportionally with current squared (I²R). Applications operating near the 380 mA current limit should calculate thermal impact.

Q: Are both parts RoHS compliant?

A: Yes. The CML0510-3N0-CNH is RoHS Compliant; the ATFC-0402-3N0B-T is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What is the moisture sensitivity level for both parts?

A: Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
