CMLB063T-R10MS Equivalent & Substitute Parts

Part Overview

The CMLB063T-R10MS is a 100 nH shielded inductor manufactured by Delta Electronics/Cyntec, rated for 40 A continuous current with a maximum DC resistance of 0.99 mOhm. This surface mount component operates across the temperature range of -55°C to 125°C and is classified as Active product status. Substitute parts are identified when equivalent electrical performance cannot be sourced from the primary manufacturer or when inventory constraints require alternative sourcing options while maintaining functional compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMLB063T-R10MS is determined by the following critical parameters:

• Inductance value must be 100 nH
• Inductance tolerance must accommodate circuit design margins
• Current rating must support the application's maximum continuous current requirement
• Saturation current (Isat) must exceed the application's peak transient current
• DC resistance must remain within acceptable limits for thermal and efficiency considerations
• Shielding configuration must match to prevent electromagnetic interference effects
• Operating temperature range must encompass the application environment
• Surface mount packaging and nonstandard case dimensions must be compatible with PCB layout

The PA4341.101NLT from Pulse Electronics meets the core inductance specification of 100 nH and maintains shielded construction. However, substitution requires engineering evaluation of the reduced current rating (32.5 A versus 40 A) and increased DC resistance (1.7 mOhm versus 0.99 mOhm maximum) relative to application demands.

Parameter Comparison

Engineering Selection Recommendations

Selection between CMLB063T-R10MS and PA4341.101NLT must be based on application-specific current and thermal requirements:

The CMLB063T-R10MS is the primary choice when continuous current demands approach or exceed 32.5 A, or when DC resistance contribution to thermal budget is critical. The 0.99 mOhm maximum resistance and 40 A current rating provide superior performance margin in high-current applications.

The PA4341.101NLT from Pulse Electronics is suitable for applications where continuous current remains below 32.5 A and the increased DC resistance (1.7 mOhm maximum) does not compromise thermal or efficiency specifications. This substitute offers higher saturation current (60 A) for transient margin and maintains ROHS3 compliance and AEC-Q200 automotive qualification.

Both parts are Active status products with unlimited moisture sensitivity rating and REACH unaffected classification. PCB layout compatibility must be verified due to dimensional differences: the PA4341.101NLT is 0.65 mm longer and 0.30 mm wider than the CMLB063T-R10MS, though both maintain identical 3.00 mm seated height.

Frequently Asked Questions (FAQ)

Q: Can PA4341.101NLT replace CMLB063T-R10MS in all applications?

A: Substitution is valid only when application continuous current remains at or below 32.5 A and the increased DC resistance of 1.7 mOhm (versus 0.99 mOhm) is acceptable for thermal and efficiency calculations. Applications requiring the full 40 A rating or lower resistance must use the CMLB063T-R10MS.

Q: What is the impact of the ±30% inductance tolerance on PA4341.101NLT versus ±20% on CMLB063T-R10MS?

A: The wider tolerance on the substitute part requires circuit design verification to ensure frequency response and impedance matching remain within specification across the full tolerance band. Applications with tight frequency or impedance requirements may require the tighter tolerance of the primary part.

Q: Are the physical dimension differences between these parts critical?

A: The PA4341.101NLT is 0.65 mm longer (7.60 mm versus 6.95 mm) and 0.30 mm wider (6.90 mm versus 6.60 mm). PCB layout must be verified to confirm the substitute footprint fits within available space. Both parts maintain identical 3.00 mm maximum seated height.

Q: Does the operating temperature range difference affect substitution?

A: The CMLB063T-R10MS operates from -55°C to 125°C, while PA4341.101NLT operates from -40°C to 125°C. Applications requiring operation below -40°C must use the CMLB063T-R10MS. For standard industrial and commercial temperature ranges, both parts are compatible.

Q: What compliance certifications apply to both parts?

A: Both CMLB063T-R10MS and PA4341.101NLT are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. The PA4341.101NLT additionally carries AEC-Q200 automotive qualification.
