MLP2520P2R2S Equivalent & Substitute Parts

Part Overview

The MLP2520P2R2S is a 2.2 µH shielded multilayer inductor manufactured by TDK Corporation, rated for 1.2 A with a maximum DC resistance of 208mOhm. This component is packaged in the 1008 (2520 Metric) surface mount format and operates across the temperature range of -40°C to 125°C. The part is currently classified as obsolete, making identification of suitable equivalent and substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MLP2520P2R2S is determined by the following critical parameters:

• Inductance Value: 2.2 µH (±20% tolerance allows 1.76 µH to 2.64 µH)
• Current Rating: Minimum 1.2 A required
• Package / Case: 1008 (2520 Metric) surface mount format
• Shielding: Shielded configuration
• Operating Temperature Range: -40°C ~ 125°C minimum
• DC Resistance: Lower DCR values are acceptable as they represent improved performance
• RoHS Compliance: ROHS3 Compliant status required

The three substitute parts identified meet these core substitution criteria while offering varying performance characteristics in terms of current capacity and DC resistance.

Parameter Comparison

Engineering Selection Recommendations

MLP2520S2R2ST0S1: This substitute offers improved DC resistance performance (143mOhm vs. 208mOhm) while maintaining the same current rating of 1.2 A. The inductance value of 2.5 µH falls within the ±20% tolerance band of the original specification. Product status is active with full ROHS3 compliance and unlimited moisture sensitivity rating. This part is suitable for applications where lower losses are beneficial.

MLP2520V2R2ST0S1: This substitute maintains the exact inductance value of 2.2 µH with improved DC resistance (156mOhm vs. 208mOhm). The current rating is 1.1 A, which is marginally lower than the original 1.2 A specification. Product status is active with full ROHS3 compliance. This part is appropriate for applications operating at or below 1.1 A.

VLS252012HBX-2R2M-1: This substitute represents a different inductor technology (drum core, wirewound with metal core) while maintaining the same 2.2 µH inductance and package format. It offers superior current handling capability at 2.3 A and the lowest DC resistance at 102mOhm. The operating temperature range extends to 105°C maximum, which is 20°C lower than the original part. Product status is active with full ROHS3 compliance. This part is suitable for high-current applications requiring lower DC resistance.

Frequently Asked Questions (FAQ)

Q: Can MLP2520S2R2ST0S1 be used as a direct replacement for MLP2520P2R2S?

A: Yes, within design constraints. The inductance value of 2.5 µH is within the ±20% tolerance specification of the 2.2 µH requirement. Current rating and package format are identical. The improved DC resistance (143mOhm vs. 208mOhm) represents enhanced performance. Verify that the 0.3 µH inductance increase does not impact circuit performance.

Q: What are the limitations of MLP2520V2R2ST0S1?

A: The current rating of 1.1 A is 0.1 A lower than the original 1.2 A specification. This part is suitable only for applications operating at or below 1.1 A. All other parameters, including inductance, package, and temperature range, are compatible.

Q: Why does VLS252012HBX-2R2M-1 have a lower maximum operating temperature?

A: The VLS252012HBX-2R2M-1 uses a different core material (metal) and construction method (drum core, wirewound) compared to the multilayer ferrite design of the original part. The maximum operating temperature of 105°C is a characteristic of this technology. Applications requiring operation above 105°C must use MLP2520S2R2ST0S1 or MLP2520V2R2ST0S1.

Q: Are all substitute parts available in the same packaging options?

A: MLP2520S2R2ST0S1 and VLS252012HBX-2R2M-1 are available in Cut Tape (CT) & Digi-Reel® packaging. MLP2520V2R2ST0S1 is available in Tape & Reel (TR) packaging. Verify packaging compatibility with your procurement and assembly processes.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All parts have Moisture Sensitivity Level 1 (Unlimited).
