CMLB063T-1R0MS Equivalent & Substitute Parts

Part Overview

The CMLB063T-1R0MS is a 1 µH shielded inductor manufactured by Delta Electronics/Cyntec, rated for 13 A continuous current with a maximum DC resistance of 7.25 mOhm. This surface mount component is designed for applications requiring low inductance values with high current capacity in a compact nonstandard package. The part is currently active in production and widely available in inventory. Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while meeting application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CMLB063T-1R0MS are qualified based on the following electrical and mechanical criteria:

Critical Matching Parameters:

• Inductance value: 1 µH (within ±20% tolerance band)
• Inductance test frequency: 100 kHz
• Shielding type: Shielded construction
• Mounting type: Surface Mount
• Package classification: Nonstandard
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Allowable Variation Parameters:

• Current rating: Substitute must support minimum 13 A continuous operation
• DC resistance: Substitute DCR must not exceed 7.25 mOhm maximum
• Saturation current: Substitute Isat must meet or exceed 14.6 A
• Operating temperature range: Substitute must cover the -55°C to 125°C range or be compatible with the application's actual operating window

The PA4341.102NLT from Pulse Electronics meets these substitution criteria with equivalent inductance, shielding, and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The PA4341.102NLT qualifies as a substitute for the CMLB063T-1R0MS based on matching inductance value, tolerance, shielding type, and regulatory compliance. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 with unlimited moisture sensitivity protection.

Application-Specific Considerations:

When the CMLB063T-1R0MS is unavailable, the PA4341.102NLT may be selected provided the following conditions are met:

• Operating current does not exceed 11 A continuous (the substitute's rated current limit)
• Operating temperature range does not require operation below -40°C (the substitute's lower temperature limit is -40°C versus the main part's -55°C)
• PCB layout accommodates the slightly larger footprint (7.60mm L x 6.90mm W versus 6.95mm L x 6.60mm W)
• The higher DC resistance of 10 mOhm (versus 7.25 mOhm) is acceptable for the application's thermal and efficiency requirements

Both parts maintain identical seated height of 3.00 mm, supporting direct mechanical substitution in standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the PA4341.102NLT replace the CMLB063T-1R0MS in all applications?

A: The PA4341.102NLT is electrically equivalent for inductance and shielding characteristics. However, substitution is conditional on three factors: (1) the application's continuous current requirement does not exceed 11 A, (2) the operating temperature range does not require sustained operation below -40°C, and (3) the increased DC resistance of 10 mOhm versus 7.25 mOhm is acceptable for the circuit's power dissipation budget.

Q: What is the difference in DC resistance between these parts?

A: The CMLB063T-1R0MS has a maximum DC resistance of 7.25 mOhm, while the PA4341.102NLT has a maximum of 10 mOhm. This 2.75 mOhm difference results in higher resistive losses in the substitute part. At 11 A, this represents approximately 0.30 W additional power dissipation compared to the main part at the same current.

Q: Are the physical dimensions compatible for PCB layout?

A: Both parts have identical seated height of 3.00 mm. However, the PA4341.102NLT footprint is slightly larger: 7.60mm L x 6.90mm W compared to 6.95mm L x 6.60mm W for the CMLB063T-1R0MS. PCB layout must accommodate this 0.65 mm length and 0.30 mm width increase.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the CMLB063T-1R0MS and PA4341.102NLT are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level). Both are classified under HTSUS code 8504.50.8000 and ECCN EAR99.

Q: What is the saturation current difference?

A: The CMLB063T-1R0MS has a saturation current (Isat) of 14.6 A, while the PA4341.102NLT has an Isat of 22 A. The substitute part provides greater saturation margin, which is advantageous for transient current handling and design robustness.

Q: Can the PA4341.102NLT be used in applications requiring -55°C operation?

A: No. The PA4341.102NLT is rated for -40°C to 125°C operation, while the CMLB063T-1R0MS supports -55°C to 125°C. Applications requiring sustained operation at -55°C must use the original part or identify an alternative substitute with matching low-temperature capability.
