Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS252008ET-6R8M is determined by the following critical parameters:

• Inductance Value: Must be 6.8 µH to maintain circuit performance
• Current Rating: Substitute must support minimum 500 mA operation
• DC Resistance: Lower DCR values are acceptable as they reduce power dissipation
• Core Type and Shielding: Ferrite core with shielding must be maintained for electromagnetic compatibility
• Mounting and Package Footprint: Surface mount configuration with compatible physical dimensions
• Environmental Compliance: RoHS3 compliance and MSL rating must be maintained

The VLS252010CX-6R8M-1 meets these substitution criteria with improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both components maintain identical inductance values, core material, shielding configuration, and environmental operating range. The substitute part offers superior electrical performance with 72% reduction in DC resistance (372 mOhm versus 818 mOhm) and 72% increase in current rating capacity (860 mA versus 500 mA), while maintaining the same footprint dimensions and compliance certifications. The VLS252010CX-6R8M-1 carries Active product status, ensuring long-term availability and support for new designs.

Frequently Asked Questions (FAQ)

Q: Can the VLS252010CX-6R8M-1 be used as a direct replacement for the VLS252008ET-6R8M?

A: Yes. Both parts share identical inductance (6.8 µH), core material (ferrite), shielding, tolerance (±20%), operating temperature range (-40°C ~ 105°C), and footprint dimensions (2.50mm x 2.00mm). The substitute meets or exceeds all electrical requirements of the original part.

Q: What is the difference in height between these two parts?

A: The VLS252008ET-6R8M has a maximum seated height of 0.031" (0.80mm), while the VLS252010CX-6R8M-1 has a maximum seated height of 0.039" (1.00mm). This 0.008" (0.20mm) difference must be evaluated for PCB layout clearance in height-constrained applications.

Q: Why does the substitute part have lower DC resistance?

A: The VLS252010CX-6R8M-1 represents an improved design iteration with optimized winding configuration, resulting in 372 mOhm maximum DCR compared to 818 mOhm in the original part. This reduction decreases power dissipation and heat generation during operation.

Q: Are both parts RoHS compliant?

A: Yes. Both the VLS252008ET-6R8M and VLS252010CX-6R8M-1 are ROHS3 compliant with MSL rating of 1 (Unlimited moisture sensitivity level).

Q: What is the significance of the product status difference?

A: The VLS252008ET-6R8M is marked Not For New Designs, indicating TDK has discontinued active development and support. The VLS252010CX-6R8M-1 carries Active status, ensuring continued manufacturing, availability, and technical support for current and future applications.
