Key Parameters

Substitute Part Grouping Explanation

Substitution of the CMLE053T-2R2MS is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 2.2 µH (±20% tolerance acceptable)
• Shielding requirement: Shielded construction
• Mounting type: Surface mount
• Core material classification: Metal or equivalent shielded construction

Secondary Compatibility Factors:

• Current rating: Minimum 5.5 A acceptable for applications not requiring full 6.9 A capacity
• DC resistance: Up to 35mOhm acceptable where thermal performance permits
• Operating temperature range: Minimum -40°C to 125°C acceptable for standard industrial applications
• Package classification: Nonstandard surface mount packages with compatible footprint dimensions
• Compliance: ROHS3 and REACH status maintained

The PA4340.222NLT qualifies as a substitute based on matching inductance, shielding, surface mount configuration, and compliance certifications, with trade-offs in current rating and DC resistance.

Engineering Selection Recommendations

CMLE053T-2R2MS (Primary Part):

• Select when continuous current requirement is 6.9 A or higher
• Select when DC resistance must not exceed 24mOhm
• Select when operating temperature must reach -55°C
• Select when PCB space is constrained (smaller footprint: 4.85mm x 4.70mm)
• Active production status with 877 units in stock

PA4340.222NLT (Substitute Part):

• Select when continuous current requirement is 5.5 A or lower
• Select when higher DC resistance (35mOhm) is acceptable within thermal budget
• Select when minimum operating temperature of -40°C is sufficient
• Select when larger footprint (6.00mm x 5.40mm) is accommodated on PCB
• Active production status with 1953 units in stock
• Carries AEC-Q200 automotive qualification rating

Both parts maintain ROHS3 compliance, MSL 1 rating, and shielded construction. Selection between these parts depends on application-specific requirements for current capacity, thermal performance, temperature range, and available board space.

Frequently Asked Questions (FAQ)

Q: Can PA4340.222NLT replace CMLE053T-2R2MS in all applications?

A: No. The PA4340.222NLT has a lower continuous current rating (5.5 A versus 6.9 A) and higher DC resistance (35mOhm versus 24mOhm). Substitution is valid only when the application current does not exceed 5.5 A and the increased power dissipation from higher resistance is acceptable.

Q: What is the impact of the 11mOhm difference in DC resistance?

A: At 5.5 A continuous current, the PA4340.222NLT dissipates approximately 1.06 watts compared to 0.73 watts for the CMLE053T-2R2MS. This 45% increase in power dissipation must be evaluated against thermal design margins in the application.

Q: Are the physical dimensions compatible?

A: No. The PA4340.222NLT (6.00mm x 5.40mm) is larger than the CMLE053T-2R2MS (4.85mm x 4.70mm). PCB footprint and layout must be verified before substitution. Both parts have identical seated height (3.00mm).

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant with MSL 1 rating. The PA4340.222NLT additionally carries AEC-Q200 automotive qualification, which the CMLE053T-2R2MS does not specify.

Q: What is the temperature range difference?

A: The CMLE053T-2R2MS operates from -55°C to 125°C, while the PA4340.222NLT operates from -40°C to 125°C. The substitute cannot be used in applications requiring operation below -40°C.

Q: Are both parts currently available?

A: Yes. CMLE053T-2R2MS has 877 units in stock, and PA4340.222NLT has 1953 units in stock, both listed as active products.
