CMLE041B-2R2MS Equivalent & Substitute Parts

Part Overview

The CMLE041B-2R2MS is a 2.2 µH shielded inductor manufactured by Delta Electronics/Cyntec, designed for surface mount applications requiring fixed inductance in compact form factors. This component is rated for 3.7 A continuous current with a maximum DC resistance of 82 Ohm and operates across the industrial temperature range of -55°C to 125°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent inductance values, current ratings, shielding characteristics, and operating temperature ranges align within acceptable engineering tolerances, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMLE041B-2R2MS is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 2.2 µH (within ±20% tolerance specification)
• Shielding requirement: Shielded construction
• Operating temperature range: -55°C ~ 125°C minimum
• Mounting type: Surface Mount
• Inductance test frequency: 100 kHz

Secondary Compatibility Factors:

• Current rating: Minimum 2.9 A continuous (acceptable for applications designed for 3.7 A rated component)
• DC resistance: Comparable performance within nonstandard package constraints
• Package dimensions: Nonstandard form factor with maximum height of 0.047" (1.20mm)
• Compliance: RoHS and REACH status alignment

The MPI4012V2-2R2-R qualifies as a direct substitute based on matching inductance, shielding, temperature range, and surface mount configuration. Saturation current (4.2 A) and self-resonant frequency (35 MHz) provide additional design margin for applications within the specified current envelope.

Engineering Selection Recommendations

CMLE041B-2R2MS (Primary Component)

Active product status with full RoHS3 compliance and REACH unaffected designation. Inventory availability of 1,174 pieces supports production continuity. Specified for 3.7 A continuous current operation with 82 Ohm maximum DC resistance. Suitable for applications requiring the full rated current envelope within the nonstandard package footprint.

MPI4012V2-2R2-R (Substitute Component)

Active product status with RoHS compliance and REACH unaffected designation. Inventory availability of 724 pieces. Rated for 2.9 A continuous current with 90 mOhm maximum DC resistance and 4.2 A saturation current. Drum core, wirewound construction with specified 35 MHz self-resonant frequency. Suitable for applications operating at or below 2.9 A continuous current. Dimensions vary slightly (0.160" L x 0.171" W versus 0.173" L x 0.165" W) within the same maximum height constraint of 0.047" (1.20mm), requiring PCB layout verification for mechanical fit.

Both components maintain identical operating temperature range (-55°C ~ 125°C), inductance test frequency (100 kHz), and moisture sensitivity classification, enabling functional equivalence within current rating constraints.

Frequently Asked Questions (FAQ)

Q: Can MPI4012V2-2R2-R replace CMLE041B-2R2MS in all applications?

A: Substitution is valid for applications operating at continuous currents of 2.9 A or below. Applications requiring the full 3.7 A continuous rating must retain the CMLE041B-2R2MS. Both components share identical inductance (2.2 µH), tolerance (±20%), shielding, and operating temperature range (-55°C ~ 125°C).

Q: What are the dimensional differences between these parts?

A: CMLE041B-2R2MS measures 0.173" L x 0.165" W (4.40mm x 4.20mm). MPI4012V2-2R2-R measures 0.160" L x 0.171" W (4.06mm x 4.35mm). Both share identical maximum seated height of 0.047" (1.20mm). PCB layout verification is required to confirm mechanical fit within the design footprint.

Q: How do DC resistance values affect substitution?

A: CMLE041B-2R2MS specifies 82 Ohm maximum DC resistance, while MPI4012V2-2R2-R specifies 90 mOhm maximum. The MPI4012V2-2R2-R exhibits significantly lower DC resistance, resulting in reduced power dissipation and heat generation at equivalent current levels. This characteristic is advantageous for thermal management in current-limited applications.

Q: Are both components RoHS compliant?

A: CMLE041B-2R2MS is RoHS3 compliant. MPI4012V2-2R2-R is RoHS compliant. Both maintain MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status, supporting equivalent environmental and regulatory requirements.

Q: What is the significance of the 35 MHz self-resonant frequency for MPI4012V2-2R2-R?

A: The 35 MHz self-resonant frequency indicates the frequency at which the inductor's impedance transitions from inductive to capacitive behavior. This parameter is not specified for CMLE041B-2R2MS. For applications operating well below 35 MHz, this characteristic does not affect substitution validity. High-frequency circuit designs should evaluate this parameter against specific frequency requirements.

Q: What is the saturation current difference between these components?

A: CMLE041B-2R2MS saturates at 3.8 A, while MPI4012V2-2R2-R saturates at 4.2 A. Saturation current represents the threshold beyond which inductance degrades significantly. The MPI4012V2-2R2-R provides higher saturation margin, but its continuous current rating remains limited to 2.9 A, establishing the practical operating ceiling for substitution applications.
