Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMLB063T-220MS is determined by the following critical parameters:

• Inductance value must be 22 µH with ±20% tolerance
• Shielding requirement must be maintained
• Mounting type must be surface mount
• DC resistance must not exceed 200 mOhm to ensure thermal performance equivalence
• Current rating must support minimum 2.3 A continuous operation
• Operating temperature range must encompass the application requirements
• RoHS3 compliance and MSL 1 rating must be maintained

The PA4341.223NLT from Pulse Electronics meets these substitution criteria with equivalent inductance, shielding, and mounting characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the CMLB063T-220MS and PA4341.223NLT are active production components with ROHS3 compliance and MSL 1 ratings, ensuring long-term availability and environmental regulatory compliance. The PA4341.223NLT offers superior DC resistance (190 mOhm vs. 200 mOhm) and higher saturation current (4.6 A vs. 2.5 A), providing improved thermal efficiency and headroom in saturation performance.

Selection between these parts should account for the following provided specifications: the CMLB063T-220MS supports a wider operating temperature range (-55°C to 125°C versus -40°C to 125°C), which is relevant for applications requiring extended low-temperature operation. The PA4341.223NLT has a continuous current rating of 2.0 A, which is 0.3 A lower than the main part's 2.3 A rating. Applications operating continuously above 2.0 A require the CMLB063T-220MS or verification that peak current demands do not exceed the PA4341.223NLT saturation point of 4.6 A.

Physical dimensions differ slightly: the PA4341.223NLT is 0.65mm longer and 0.30mm wider, which may impact PCB layout constraints in space-restricted designs.

Frequently Asked Questions (FAQ)

Q: Can PA4341.223NLT replace CMLB063T-220MS in all applications?

A: Substitution is valid when continuous current requirements do not exceed 2.0 A and the operating temperature range does not require operation below -40°C. Both parts maintain identical inductance (22 µH ±20%), shielding, and mounting type. Verify PCB layout accommodates the slightly larger footprint (7.60mm x 6.90mm vs. 6.95mm x 6.60mm).

Q: What is the impact of the 10 mOhm difference in DC resistance?

A: The PA4341.223NLT has lower DC resistance (190 mOhm vs. 200 mOhm), resulting in reduced resistive losses and lower heat generation. This represents improved performance in thermal efficiency.

Q: Are there temperature range limitations for substitution?

A: The CMLB063T-220MS operates from -55°C to 125°C, while the PA4341.223NLT operates from -40°C to 125°C. Applications requiring operation below -40°C must use the CMLB063T-220MS.

Q: How do saturation current ratings affect substitution?

A: The PA4341.223NLT has higher saturation current (4.6 A vs. 2.5 A). Both parts support the same continuous current rating of 2.0 A minimum. The higher saturation rating in the substitute provides additional margin before inductance degradation occurs.

Q: Are both parts RoHS and MSL compliant?

A: Yes. Both CMLB063T-220MS and PA4341.223NLT are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory compliance and handling flexibility.
