Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMLB053T-1R0MS is determined by the following critical parameters:

• Inductance Value: Must be 1 µH with ±20% tolerance
• Shielding Type: Must be shielded construction
• Mounting Configuration: Must be surface mount
• Current Handling: Substitute must support minimum 9.8 A continuous current rating
• DC Resistance: Must not exceed 12 mOhm maximum
• Temperature Range: Must cover the operating window of -55°C to 125°C or a subset thereof
• Packaging Format: Tape & Reel preferred for production compatibility
• Compliance: RoHS3 compliance required

The PA4340.102NLT from Pulse Electronics meets the core electrical and mechanical criteria for substitution within this category.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (CMLB053T-1R0MS): Recommended for applications requiring the full -55°C to 125°C operating range and 9.8 A continuous current capacity. Active product status with established supply chain (761 pcs in stock).

Substitute Part (PA4340.102NLT): Acceptable for applications where continuous current demand does not exceed 7 A and operating temperature remains within -40°C to 125°C. This part carries AEC-Q200 automotive qualification and ROHS3 compliance. Available inventory of 884 pcs supports production requirements.

Both parts maintain identical inductance specifications, shielding characteristics, and packaging formats. Selection between primary and substitute should be based on application current requirements and minimum operating temperature constraints.

Frequently Asked Questions (FAQ)

Q: Can PA4340.102NLT replace CMLB053T-1R0MS in all applications?

A: No. The PA4340.102NLT is rated for 7 A continuous current versus the CMLB053T-1R0MS at 9.8 A. Substitution is valid only when circuit current demand does not exceed 7 A. Additionally, the substitute part's minimum operating temperature is -40°C, compared to -55°C for the main part.

Q: What is the significance of the DC resistance difference (12 mOhm vs 14 mOhm)?

A: The 2 mOhm difference represents a 16.7% increase in DC resistance for the substitute. In applications sensitive to resistive losses or thermal dissipation, this variance must be evaluated against circuit performance requirements.

Q: Are both parts pin-compatible?

A: Both parts are surface mount inductors with identical inductance values and shielded construction. Mechanical compatibility depends on PCB footprint design. Verify physical dimensions: CMLB053T-1R0MS is 4.85mm × 4.70mm × 3.00mm; PA4340.102NLT is 6.00mm × 5.40mm × 3.00mm.

Q: What compliance certifications apply to substitution decisions?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. The PA4340.102NLT carries additional AEC-Q200 automotive qualification. Compliance requirements do not restrict substitution eligibility.

Q: How does saturation current affect substitution suitability?

A: Saturation current indicates the point at which inductance begins to degrade. The CMLB053T-1R0MS saturates at 8.5 A; the PA4340.102NLT at 11 A. For applications operating near saturation thresholds, the substitute's higher saturation rating may provide additional margin.
