Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMLB063T-8R2MS is determined by the following criteria:

Primary Electrical Parameters:

• Inductance value must be 8.2 µH with ±20% tolerance
• DC resistance must not exceed 60mOhm maximum
• Current rating must support minimum 4.5 A continuous operation
• Saturation current must meet or exceed 4.92 A

Mechanical & Environmental Parameters:

• Shielded construction required
• Surface mount packaging required
• Operating temperature range must encompass -55°C ~ 125°C or be compatible with application requirements
• Nonstandard package case acceptable if physical dimensions permit board-level integration

Compliance & Regulatory:

• ROHS3 compliance required
• Moisture sensitivity level 1 (unlimited) acceptable

The PA4341.822NLT meets these substitution criteria with equivalent inductance and tolerance, shielded construction, and surface mount configuration. Differences in DC resistance (68mOhm vs. 60mOhm) and current rating (4 A vs. 4.5 A) represent acceptable trade-offs within the specified parameter envelope for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both the CMLB063T-8R2MS and PA4341.822NLT are active production components with ROHS3 compliance and unlimited moisture sensitivity ratings, suitable for long-term supply chain planning.

The CMLB063T-8R2MS provides the specified 4.5 A current rating and 60mOhm maximum DC resistance. Selection of this part is appropriate when the full current rating and lower resistance are required for thermal or efficiency considerations.

The PA4341.822NLT offers equivalent inductance and tolerance with higher saturation current (7.5 A) and AEC-Q200 automotive qualification. The 4 A current rating and 68mOhm DC resistance represent acceptable performance within the ±20% inductance tolerance band for applications where the lower current rating is sufficient. The slightly larger physical dimensions (7.60mm x 6.90mm vs. 6.95mm x 6.60mm) must be verified for board layout compatibility. The operating temperature range of -40°C ~ 125°C is suitable for commercial and industrial applications; verification is required if the full -55°C lower limit is necessary.

Frequently Asked Questions (FAQ)

Q: Can PA4341.822NLT replace CMLB063T-8R2MS in all applications?

A: Substitution is valid when the application current requirement does not exceed 4 A continuous operation and the operating temperature range of -40°C ~ 125°C is acceptable. The 8mOhm increase in DC resistance (68mOhm vs. 60mOhm) must be evaluated for thermal and efficiency impact in the specific circuit design.

Q: What is the impact of the different physical dimensions?

A: The PA4341.822NLT is 0.65mm longer (7.60mm vs. 6.95mm) and 0.30mm wider (6.90mm vs. 6.60mm). Both components share identical height (3.00mm). Board layout verification is required to confirm the substitute part fits within the available footprint space.

Q: Are both parts suitable for automotive applications?

A: The PA4341.822NLT carries AEC-Q200 automotive qualification. The CMLB063T-8R2MS does not list automotive certification in the provided specifications. Application requirements should determine the necessity of automotive-grade components.

Q: What is the significance of the ±20% inductance tolerance?

A: Both parts share ±20% inductance tolerance, meaning the actual inductance value may range from 6.56 µH to 9.84 µH. This tolerance band is the primary basis for substitution eligibility and must be acceptable for the circuit design.

Q: How do saturation current ratings affect substitution?

A: The CMLB063T-8R2MS saturates at 4.92 A, while the PA4341.822NLT saturates at 7.5 A. The substitute part provides greater headroom before saturation occurs. However, the continuous current rating (4 A vs. 4.5 A) is the limiting factor for sustained operation.
