Engineering Selection Recommendations

The MLP2520S2R2MT0S1 manufactured by TDK Corporation is a direct functional equivalent to the obsolete L1008L2R2MDMIT. Selection of this substitute part is supported by the following engineering factors:

Electrical Compatibility: Both components share identical inductance values (2.2 µH), current ratings (1.2 A), and tolerance specifications (±20%). The DC resistance of the TDK part (117 mOhm maximum) is marginally higher than the KEMET original (100 mOhm maximum) but remains within acceptable operating parameters for equivalent circuit performance.

Package & Mechanical Compatibility: Both parts utilize the identical 1008 (2520 Metric) surface mount package with shielded ferrite core construction, ensuring direct PCB footprint compatibility and assembly process equivalence.

Compliance & Regulatory Status: The TDK substitute maintains ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) matching the original part. Both components carry EAR99 ECCN classification.

Product Lifecycle Advantage: The MLP2520S2R2MT0S1 holds active product status with extended operating temperature range (-40°C to 125°C versus -40°C to 85°C), providing enhanced thermal margin for demanding applications and assured long-term supply availability.

Frequently Asked Questions (FAQ)

Q: Can the MLP2520S2R2MT0S1 be used as a direct replacement for the L1008L2R2MDMIT on existing PCBs?

A: Yes. Both components share identical package dimensions (1008/2520 Metric), footprint, and mounting requirements. No PCB redesign is necessary for substitution.

Q: What is the significance of the DC resistance difference (100 mOhm vs. 117 mOhm)?

A: The 17 mOhm difference represents approximately 17% higher resistance in the TDK part. For most applications operating at or below 1.2 A, this variance produces negligible additional power dissipation and remains within acceptable design margins. Circuit-specific thermal analysis is required only for applications operating continuously at maximum current ratings in thermally constrained environments.

Q: Why is the TDK part rated for a higher maximum temperature (125°C vs. 85°C)?

A: The extended temperature rating reflects TDK's component design and qualification standards. This provides additional operational margin and does not affect compatibility with designs specified for the original -40°C to 85°C range.

Q: Are both parts RoHS compliant?

A: Yes. Both the L1008L2R2MDMIT and MLP2520S2R2MT0S1 are ROHS3 compliant and carry identical moisture sensitivity level (MSL 1 - Unlimited), meeting current regulatory requirements for electronics manufacturing.

Q: What is the inductance tolerance, and does it affect circuit performance?

A: Both components carry ±20% inductance tolerance. This specification is standard for multilayer ferrite inductors in this package class. Circuit designs must account for this tolerance range in component selection and filter/impedance calculations.

Q: Is the substitute part available in the same packaging formats?

A: Yes. The MLP2520S2R2MT0S1 is supplied in Cut Tape (CT) and Digi-Reel® packaging, matching the original part's distribution format options.
