Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMLE053T-6R8MS is determined by the following critical parameters:

• Inductance value must be 6.8 µH with ±20% tolerance
• Shielding type must be shielded to maintain electromagnetic compatibility
• Current rating must meet or exceed 3.7 A continuous operation
• DC resistance must not exceed 84 mOhm to ensure thermal performance
• Mounting type must be surface mount for PCB compatibility
• Operating temperature range must encompass or exceed -55°C to 125°C
• Inductance measurement frequency must be 100 kHz

The PA4340.682NLT from Pulse Electronics meets all substitution criteria and qualifies as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The PA4340.682NLT qualifies as a direct substitute for the CMLE053T-6R8MS based on the following engineering criteria:

Both parts maintain identical inductance values and tolerance specifications at the 100 kHz test frequency. The substitute part provides superior electrical performance with a 4 A current rating versus 3.7 A, and lower DC resistance of 76.2 mOhm compared to 84 mOhm maximum, resulting in reduced thermal dissipation. Both components are ROHS3 compliant and carry MSL 1 moisture sensitivity ratings, ensuring equivalent reliability in storage and handling.

The PA4340.682NLT includes AEC-Q200 automotive qualification, providing additional quality assurance. The operating temperature range of the substitute extends to -40°C minimum versus -55°C for the main part; applications requiring operation below -40°C must retain the CMLE053T-6R8MS. Both parts are actively manufactured and available in standard tape and reel packaging.

Frequently Asked Questions (FAQ)

Q: Can PA4340.682NLT replace CMLE053T-6R8MS in all applications?

A: Yes, for applications operating within -40°C to 125°C. Applications requiring operation below -40°C must use the CMLE053T-6R8MS due to its extended lower temperature limit of -55°C.

Q: What are the physical dimension differences between these parts?

A: The CMLE053T-6R8MS measures 0.191" L x 0.185" W (4.85mm x 4.70mm), while the PA4340.682NLT measures 0.236" L x 0.213" W (6.00mm x 5.40mm). Both share identical height of 0.118" (3.00mm) when seated. PCB layout must accommodate the larger footprint of the substitute part.

Q: Are there compliance or certification differences?

A: Both parts are ROHS3 compliant and REACH unaffected. The PA4340.682NLT carries AEC-Q200 automotive qualification, which the main part does not specify. Both have ECCN EAR99 classification.

Q: How do the electrical performance characteristics compare?

A: The PA4340.682NLT provides improved performance margins with 4 A continuous current rating versus 3.7 A, and lower DC resistance of 76.2 mOhm versus 84 mOhm maximum. Saturation current is also higher at 4.3 A versus 3.6 A. These characteristics make the substitute suitable for applications with identical or higher current demands.

Q: What packaging formats are available for both parts?

A: Both the CMLE053T-6R8MS and PA4340.682NLT are supplied in Tape & Reel (TR) packaging with MSL 1 moisture sensitivity, suitable for automated assembly processes.
