Substitute Part Grouping Explanation

The PA4343.102NLT from Pulse Electronics is identified as a direct substitute for the CMLB136T-100MS based on the following substitution criteria:

Allowed Substitution Parameters:

• Shielding type: Both components are shielded inductors
• Tolerance: Both maintain ±20% tolerance
• Mounting type: Both are surface mount devices
• Package classification: Both use nonstandard package configurations
• Inductance Frequency Test: Both tested at 100 kHz
• RoHS and environmental compliance: Both ROHS3 compliant with MSL 1 (Unlimited)
• Operating temperature range compatibility: PA4343.102NLT (-40°C ~ 125°C) covers the critical upper range of CMLB136T-100MS (-55°C ~ 125°C)

Note: The PA4343.102NLT operates at different electrical specifications (1 µH inductance, 30 A current rating, 2.3 mOhm DCR) compared to the main part. Substitution is valid only when application requirements permit these parameter variations.

Parameter Comparison

Engineering Selection Recommendations

Both the CMLB136T-100MS and PA4343.102NLT maintain Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. The PA4343.102NLT includes AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. Selection between these parts depends on circuit requirements for inductance value, current handling capacity, and DC resistance characteristics. Physical dimensions differ slightly; verify PCB layout compatibility before substitution. Both components are suitable for industrial and commercial applications within their specified operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can PA4343.102NLT directly replace CMLB136T-100MS in any application?

A: Direct substitution is valid only when the application circuit can accommodate the different inductance value (1 µH vs. 10 µH), higher current rating (30 A vs. 10 A), and significantly lower DC resistance (2.3 mOhm vs. 20.7 Ohm). Circuit simulation or testing is required to confirm functional equivalence.

Q: What are the physical compatibility considerations?

A: Both components use nonstandard surface mount packages with similar footprints. The PA4343.102NLT is slightly larger (0.551" L x 0.504" W vs. 0.530" L x 0.496" W) and taller (0.256" vs. 0.236" seated height). Verify PCB layout clearances and solder reflow profiles before implementation.

Q: Are there temperature range differences?

A: The CMLB136T-100MS operates from -55°C to 125°C, while the PA4343.102NLT operates from -40°C to 125°C. For applications requiring operation below -40°C, the CMLB136T-100MS is the appropriate choice.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity). The PA4343.102NLT additionally carries AEC-Q200 automotive qualification.

Q: How do the DC resistance values affect circuit performance?

A: The PA4343.102NLT exhibits significantly lower DC resistance (2.3 mOhm vs. 20.7 Ohm), resulting in reduced power dissipation and heat generation. This difference substantially impacts thermal performance and efficiency in power delivery applications.
