Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMLB063T-100MS is determined by the following critical parameters:

Primary Electrical Criteria:

• Inductance value of 10 µH within ±20% tolerance
• Shielded construction to maintain electromagnetic isolation
• Surface mount configuration for PCB compatibility
• Operating temperature range that encompasses or exceeds -55°C to 125°C

Secondary Electrical Criteria:

• Current rating sufficient for application requirements
• DC resistance within acceptable limits for thermal and efficiency considerations
• Saturation current rating appropriate for peak current conditions

Mechanical & Compliance Criteria:

• Nonstandard package form factor compatibility
• RoHS3 compliance status
• Moisture sensitivity level MSL 1 (Unlimited)

The PA4341.103NLT from Pulse Electronics qualifies as a substitute based on matching inductance (10 µH), tolerance (±20%), shielded construction, surface mount configuration, and RoHS3 compliance. Differences in current rating, DCR, and saturation current must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the CMLB063T-100MS and PA4341.103NLT maintain Active product status with full RoHS3 compliance and unlimited moisture sensitivity ratings, ensuring long-term availability and environmental regulatory compliance.

The PA4341.103NLT carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. The molded construction type of the PA4341.103NLT differs from the metal core material of the CMLB063T-100MS, which may influence performance in specific electromagnetic environments.

Selection between these parts depends on application-specific current requirements. The CMLB063T-100MS supports 4 A continuous current with 4.9 A saturation, while the PA4341.103NLT supports 4.6 A continuous current with 6 A saturation. The PA4341.103NLT exhibits higher DC resistance (85 mOhm vs. 68 mOhm), which increases resistive losses. The CMLB063T-100MS supports extended low-temperature operation to -55°C, compared to -40°C for the PA4341.103NLT.

Frequently Asked Questions (FAQ)

Q: Can PA4341.103NLT replace CMLB063T-100MS in all applications?

A: Substitution is valid only when application current requirements do not exceed 4.6 A continuous operation. Applications requiring the full 4 A rating or extended operation below -40°C require the CMLB063T-100MS.

Q: What is the impact of higher DC resistance in the PA4341.103NLT?

A: The PA4341.103NLT exhibits 85 mOhm maximum DCR compared to 68 mOhm for the CMLB063T-100MS. This 17 mOhm difference increases resistive power dissipation proportionally to the square of current. At 4.6 A, the PA4341.103NLT dissipates approximately 1.04 W compared to 0.84 W for the CMLB063T-100MS at 4 A.

Q: Are the physical dimensions compatible?

A: Both parts use Nonstandard package form factors with identical seated height of 0.118" (3.00 mm). The CMLB063T-100MS measures 0.274" L × 0.260" W (6.95 mm × 6.60 mm), while the PA4341.103NLT measures 0.299" L × 0.272" W (7.60 mm × 6.90 mm). PCB layout verification is required to confirm footprint compatibility.

Q: What is the significance of AEC-Q200 qualification on the PA4341.103NLT?

A: AEC-Q200 certification indicates the component meets automotive industry reliability and quality standards. This qualification is relevant only for applications requiring automotive-grade components.

Q: How do saturation current ratings affect substitution?

A: The CMLB063T-100MS saturates at 4.9 A while the PA4341.103NLT saturates at 6 A. For applications with transient current peaks, the PA4341.103NLT provides higher saturation margin. However, continuous current ratings remain the limiting factor for sustained operation.
