VLS252015ET-2R2M Equivalent & Substitute Parts

Part Overview

The VLS252015ET-2R2M is a 2.2 µH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 1.25 A continuous current with a maximum DC resistance of 160mOhm. This component is packaged in the 1008 (2520 Metric) surface mount form factor and operates across the industrial temperature range of -40°C to 105°C. The part carries a "Not For New Designs" status, indicating it has been superseded in TDK's product portfolio. Identifying equivalent substitute parts is necessary for ongoing production support, legacy system maintenance, and design continuity where this inductor specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS252015ET-2R2M is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 2.2 µH (±20% tolerance band)
• Shielding type: Shielded construction
• Core material: Ferrite drum core
• Mounting type: Surface mount
• Physical dimensions: 2.50mm x 2.00mm footprint with 1.00mm maximum seated height
• Operating temperature range: -40°C to 105°C minimum

Allowable Variation Parameters:

• Current rating: May exceed 1.25 A (higher current capability is acceptable)
• DC resistance: May be lower than 160mOhm (improved performance is acceptable)
• Saturation current: May exceed 1.5A (higher saturation is acceptable)
• Package designation: Nonstandard package codes are acceptable if physical dimensions and electrical characteristics align

The VLS252010CX-2R2M-1 qualifies as a direct substitute based on matching inductance, shielding, core material, temperature range, and physical footprint, while offering improved electrical performance through higher current rating (1.58 A vs. 1.25 A) and lower DC resistance (126mOhm vs. 160mOhm).

Parameter Comparison

Engineering Selection Recommendations

The VLS252010CX-2R2M-1 is the qualified substitute for the VLS252015ET-2R2M. Both components are manufactured by TDK Corporation and maintain identical electrical specifications for inductance, tolerance, and operating temperature range. The substitute part carries Active product status, ensuring continued availability and manufacturing support, whereas the main part is designated Not For New Designs.

The substitute demonstrates superior electrical performance with increased current rating (1.58 A versus 1.25 A) and reduced DC resistance (126mOhm versus 160mOhm), providing enhanced thermal efficiency and current handling capability. Both parts maintain ROHS3 compliance and MSL Level 1 rating, confirming equivalent environmental and regulatory standing.

Physical compatibility is confirmed through identical footprint dimensions (2.50mm x 2.00mm) and maximum seated height (1.00mm), enabling direct PCB layout substitution without redesign. The substitute part's Nonstandard package designation does not affect functional compatibility, as the physical form factor and electrical characteristics remain aligned with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the VLS252010CX-2R2M-1 be used as a direct replacement for the VLS252015ET-2R2M on existing PCBs?

A: Yes. Both parts share identical physical dimensions (2.50mm x 2.00mm footprint, 1.00mm maximum height) and mounting type (surface mount), enabling direct PCB substitution without layout modification.

Q: What are the key electrical differences between these two inductors?

A: The substitute part offers improved performance: current rating increases from 1.25 A to 1.58 A, and DC resistance decreases from 160mOhm to 126mOhm. Inductance value, tolerance, and operating temperature range remain identical.

Q: Why is the main part marked "Not For New Designs"?

A: This designation indicates the VLS252015ET-2R2M has been superseded in TDK's active product portfolio. The VLS252010CX-2R2M-1 represents the current generation equivalent with Active status.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain ROHS3 compliance, MSL Level 1 rating, and identical environmental certifications, confirming equivalent regulatory standing.

Q: What does the "Nonstandard" package designation mean for the substitute part?

A: The Nonstandard package code does not affect functional compatibility. The physical form factor (2520 metric dimensions) and electrical characteristics align with the original part specification.

Q: Can the substitute part handle higher current loads than the original?

A: Yes. The substitute part is rated for 1.58 A continuous current compared to 1.25 A for the original part, providing additional current capacity for the same application.
