Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLS252008ET-2R2M is determined by the following critical parameters:

• Inductance Value: Must remain 2.2 µH with ±20% tolerance to maintain circuit performance
• Core Type and Shielding: Ferrite core with shielding must be preserved to ensure electromagnetic compatibility
• Mounting and Package: Surface mount configuration with compatible footprint dimensions (2.50mm x 2.00mm length and width)
• Operating Temperature Range: Must support -40°C ~ 105°C minimum
• Compliance Standards: RoHS3 compliance and MSL Level 1 rating required

The substitute part VLS252010CX-2R2M-1 meets these core substitution criteria while offering improved electrical performance characteristics, particularly in current handling capacity and reduced DC resistance.

Engineering Selection Recommendations

The VLS252010CX-2R2M-1 is the manufacturer-recommended substitute for the VLS252008ET-2R2M. Both components maintain identical inductance values, core materials, shielding characteristics, and operating temperature ranges. The substitute part carries Active product status, ensuring continued availability and support from TDK Corporation.

The VLS252010CX-2R2M-1 provides enhanced electrical performance with increased current rating (1.58 A versus 840 mA) and significantly reduced DC resistance (126 mOhm Max versus 290 mOhm Max). These improvements result in lower power dissipation and improved thermal performance in applications operating near the current limits of the original part.

Both components maintain full RoHS3 compliance and MSL Level 1 rating. The substitute part exhibits a marginal height increase (0.039" versus 0.031"), which must be evaluated against specific PCB layout constraints. Footprint compatibility is maintained with identical length and width dimensions.

Frequently Asked Questions (FAQ)

Q: Can the VLS252010CX-2R2M-1 be used as a direct replacement for the VLS252008ET-2R2M?

A: Yes, the VLS252010CX-2R2M-1 is the manufacturer-recommended substitute. Both parts share identical inductance values (2.2 µH), core materials (ferrite), shielding, and operating temperature ranges. The substitute part is electrically compatible for applications operating at or below 840 mA.

Q: What is the primary difference between these two inductors?

A: The VLS252010CX-2R2M-1 offers improved current handling capacity (1.58 A versus 840 mA) and reduced DC resistance (126 mOhm Max versus 290 mOhm Max). These enhancements reduce power dissipation and thermal stress in the component.

Q: Are there any PCB layout considerations when substituting these parts?

A: The substitute part has a maximum seated height of 0.039" compared to 0.031" for the original part. Verify that this 0.008" height difference does not conflict with PCB clearance requirements or component placement constraints. Footprint length and width dimensions remain identical at 2.50mm x 2.00mm.

Q: Do both parts meet the same compliance standards?

A: Yes, both the VLS252008ET-2R2M and VLS252010CX-2R2M-1 are ROHS3 compliant with MSL Level 1 rating. Both components are suitable for applications requiring these certifications.

Q: Why is the original part marked as Not For New Designs?

A: The VLS252008ET-2R2M has been superseded by newer products in TDK's portfolio. The VLS252010CX-2R2M-1 represents the current active alternative, offering improved performance characteristics while maintaining backward compatibility.
