Key Parameters

Substitute Part Grouping Explanation

Substitution of the CMLB104T-6R8MS is determined by strict equivalence in the following electrical and mechanical parameters:

Electrical equivalence requires matching inductance value (6.8 µH) and inductance tolerance (±20%), both tested at 100 kHz. The substitute part must maintain shielded construction to preserve electromagnetic isolation characteristics.

Current handling capability is evaluated through two metrics: the continuous current rating must equal or exceed the original specification (7.8 A minimum), and saturation current (Isat) must meet or exceed the original value (9.5 A minimum). DC resistance must not exceed the maximum specification (24.5 mOhm max) to ensure thermal performance equivalence.

Mechanical compatibility requires surface mount mounting type and nonstandard package classification. Operating temperature range must encompass or match the original specification (-55°C ~ 125°C).

Compliance requirements include ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited).

Parameter Comparison

Engineering Selection Recommendations

The PA4342.682NLT from Pulse Electronics qualifies as a direct substitute for the CMLB104T-6R8MS based on electrical and mechanical parameter equivalence. Both parts are Active status products with ROHS3 compliance and identical moisture sensitivity ratings.

The substitute part demonstrates superior electrical performance in current handling (8.5 A vs. 7.8 A) and saturation current (14.6 A vs. 9.5 A), with equivalent or improved DC resistance (23.3 mOhm vs. 24.5 mOhm max). Both parts maintain identical inductance values, tolerances, and shielded construction.

The operating temperature range of the substitute part (-40°C ~ 125°C) is narrower at the low temperature end compared to the original specification (-55°C ~ 125°C). Selection should account for application requirements at temperatures below -40°C.

Both parts are classified as Nonstandard package types and are suitable for surface mount applications with identical mechanical mounting requirements.

Frequently Asked Questions (FAQ)

Q: What determines if PA4342.682NLT can replace CMLB104T-6R8MS?

A: Substitution is valid when inductance value (6.8 µH), inductance tolerance (±20%), shielded construction, surface mount mounting type, and nonstandard package classification are identical. Current rating and saturation current of the substitute must equal or exceed the original part. DC resistance must not exceed the maximum specification. Both parts must maintain ROHS3 compliance and Moisture Sensitivity Level 1.

Q: Are there differences in current handling between these parts?

A: Yes. The PA4342.682NLT has a higher continuous current rating (8.5 A vs. 7.8 A) and higher saturation current (14.6 A vs. 9.5 A). This makes the substitute suitable for applications requiring the original part's current specifications and for designs with higher current margins.

Q: Does the operating temperature range difference affect substitution?

A: The PA4342.682NLT operates from -40°C to 125°C, while the CMLB104T-6R8MS operates from -55°C to 125°C. The substitute part is not suitable for applications requiring operation below -40°C. For applications within the -40°C to 125°C range, the substitute is fully compatible.

Q: Are the physical dimensions compatible?

A: Both parts are classified as Nonstandard package type and are surface mount components. The CMLB104T-6R8MS measures 10.85mm L x 10.00mm W x 4.00mm H (max seated height). The PA4342.682NLT measures 11.50mm L x 10.30mm W x 4.00mm H (max seated height). Physical layout verification is required for space-constrained applications.

Q: What is the DC resistance difference and does it matter?

A: The PA4342.682NLT has lower DC resistance (23.3 mOhm max vs. 24.5 mOhm max). Lower DC resistance reduces resistive losses and heat generation, providing improved thermal performance. This is a beneficial characteristic for the substitute part.

Q: Are both parts RoHS compliant?

A: Yes. Both the CMLB104T-6R8MS and PA4342.682NLT are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting identical environmental and regulatory requirements.
