Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMLB063T-2R2MS is determined by the following critical parameters:

• Inductance Value: Must be 2.2 µH with ±20% tolerance
• Current Rating: Minimum 8.0 A continuous current capability
• DC Resistance: Maximum 20mOhm (allowing for minor variation while maintaining thermal performance)
• Saturation Current: Minimum 10.5 A to ensure stable operation under transient conditions
• Shielding: Must be shielded to maintain electromagnetic compatibility
• Mounting Type: Surface mount configuration required
• Operating Temperature: Must support -40°C minimum to 125°C maximum
• Package Compatibility: Nonstandard surface mount package with compatible footprint dimensions

The PA4341.222NLT meets these substitution criteria with equivalent inductance, acceptable current ratings within the specified range, and compatible thermal and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CMLB063T-2R2MS and PA4341.222NLT are Active product status components with ROHS3 compliance and unlimited moisture sensitivity level ratings, suitable for production applications. The PA4341.222NLT carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. Selection between these parts should be based on specific application requirements regarding minimum operating temperature (-55°C vs -40°C lower limit) and DC resistance tolerance (15mOhm vs 20mOhm maximum). Both components maintain equivalent inductance performance at the 100 kHz test frequency and support the required current and saturation specifications for this product category.

Frequently Asked Questions (FAQ)

Q: Can PA4341.222NLT replace CMLB063T-2R2MS in all applications?

A: The PA4341.222NLT is compatible for applications operating at -40°C or above. Applications requiring operation below -40°C must use the CMLB063T-2R2MS due to its extended lower temperature rating of -55°C.

Q: What is the significance of the 5mOhm difference in DC resistance?

A: The PA4341.222NLT has a maximum DC resistance of 20mOhm compared to 15mOhm for the CMLB063T-2R2MS. This 5mOhm difference results in slightly higher power dissipation. For applications sensitive to thermal performance, verify that the 20mOhm specification remains within acceptable limits.

Q: Are the physical dimensions compatible?

A: Both components use nonstandard surface mount packages with different dimensions. CMLB063T-2R2MS measures 6.95mm × 6.60mm × 3.00mm (max height), while PA4341.222NLT measures 7.60mm × 6.90mm × 3.00mm (max height). PCB layout verification is required before substitution.

Q: What does AEC-Q200 qualification mean for the PA4341.222NLT?

A: AEC-Q200 is an automotive industry standard qualification indicating the component meets stringent reliability and quality requirements for automotive applications. This certification is not listed for the CMLB063T-2R2MS.

Q: Are both parts available in the same packaging format?

A: Yes, both components are supplied in Tape & Reel (TR) packaging, maintaining supply chain compatibility.
