Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS252015ET-6R8M is determined by the following critical parameters:

• Inductance Value: Must be 6.8 µH (±20% tolerance)
• Core Material & Shielding: Ferrite material with shielded construction
• Mounting Type: Surface mount configuration
• Physical Dimensions: 2.50mm L × 2.00mm W footprint compatibility
• Current Handling: Minimum 730 mA rating required
• DC Resistance: Lower DCR values are acceptable as they represent improved performance
• Temperature Range: Must support -40°C minimum operating temperature
• Compliance: ROHS3 compliance required

The identified substitute parts meet these criteria while offering improved electrical characteristics in specific parameters.

Parameter Comparison

Engineering Selection Recommendations

VLS252010CX-6R8M-1 (TDK Corporation)

This substitute maintains TDK Corporation manufacturing continuity while offering improved electrical performance. The part delivers 860 mA current rating versus the original 730 mA, with reduced DC resistance of 372 mOhm compared to 480 mOhm. Operating temperature range remains -40°C to 105°C, matching the original specification. The component carries Active product status and maintains ROHS3 compliance. Physical footprint and height are identical to the original part, ensuring direct PCB compatibility.

ASPI-2515-6R8M-T2 (Abracon LLC)

This substitute provides the highest current rating at 900 mA and the lowest DC resistance at 295 mOhm, representing the most capable option electrically. The part supports an extended upper operating temperature of 120°C, though the lower temperature limit is -25°C rather than -40°C. Height is increased to 1.50 mm compared to 1.00 mm, requiring verification of available PCB clearance. The component carries Active product status and maintains ROHS3 compliance. Footprint dimensions remain compatible at 2.50mm × 2.00mm.

Frequently Asked Questions (FAQ)

Q: Can VLS252010CX-6R8M-1 be used as a direct replacement for VLS252015ET-6R8M?

A: Yes. Both parts share identical inductance (6.8 µH), tolerance (±20%), physical footprint (2.50mm × 2.00mm), height (1.00 mm), and operating temperature range (-40°C to 105°C). The substitute offers improved current handling (860 mA vs 730 mA) and lower DC resistance (372 mOhm vs 480 mOhm), making it functionally superior for the same application space.

Q: What is the primary limitation of ASPI-2515-6R8M-T2 as a substitute?

A: The increased height of 1.50 mm versus the original 1.00 mm requires verification of available vertical clearance on the PCB. Additionally, the minimum operating temperature is -25°C rather than -40°C, which may be a constraint for applications requiring full -40°C operation.

Q: Are all three parts ROHS3 compliant?

A: Yes. The original VLS252015ET-6R8M and both substitute parts (VLS252010CX-6R8M-1 and ASPI-2515-6R8M-T2) carry ROHS3 compliance certification.

Q: What is the significance of the "Not For New Designs" status on the original part?

A: This status indicates that TDK Corporation has discontinued the VLS252015ET-6R8M for new design applications. Both substitute parts carry Active product status, ensuring long-term availability and manufacturing support for ongoing production requirements.

Q: Do the substitute parts maintain the same inductance tolerance?

A: Yes. All three parts maintain ±20% inductance tolerance, ensuring consistent performance across the specified tolerance band.

Q: Which substitute offers the best electrical performance?

A: ASPI-2515-6R8M-T2 provides the lowest DC resistance (295 mOhm) and highest current rating (900 mA), representing the most capable electrical performance. However, PCB height clearance must be verified due to the increased 1.50 mm seated height.
