Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLS2012ET-R68N is determined by the following critical parameters:

• Inductance Value: Must remain 680 nH to maintain circuit functionality
• Shielding: Must be shielded to preserve electromagnetic isolation properties
• Mounting Type: Must be surface mount to ensure PCB compatibility
• Operating Temperature Range: Must support -40°C ~ 105°C minimum
• RoHS & Environmental Compliance: Must maintain ROHS3 compliance and REACH unaffected status
• Current Rating & DC Resistance: Substitute must meet or exceed the original specifications to ensure thermal and electrical performance

The VLS201610CX-R68M-1 qualifies as a direct substitute based on these parameters. It maintains the same inductance value, shielding type, surface mount configuration, and environmental compliance while offering improved current handling (2.19 A vs. 1.7 A) and comparable DC resistance (76 mOhm vs. 66 mOhm).

Parameter Comparison

Engineering Selection Recommendations

The VLS201610CX-R68M-1 is the recommended substitute for the VLS2012ET-R68N based on the following factors:

• Product Status: The substitute is classified as Active, ensuring continued availability and manufacturer support, whereas the original part is Not For New Designs
• Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements
• Electrical Performance: The substitute provides superior current handling capacity (2.19 A vs. 1.7 A) and saturation current (2.52 A vs. 1.7 A), offering design margin for thermal stability
• Inductance Tolerance: The substitute offers tighter tolerance (±20% vs. ±30%), improving circuit predictability
• Physical Compatibility: The substitute features a smaller footprint (2.00mm x 1.60mm vs. 2.00mm x 2.00mm) and lower profile (1.00mm vs. 1.20mm), providing PCB layout flexibility
• Thermal Range: Both parts support identical operating temperature ranges (-40°C ~ 105°C)

Frequently Asked Questions (FAQ)

Q: Can the VLS201610CX-R68M-1 be used as a direct replacement for the VLS2012ET-R68N?

A: Yes. Both parts maintain 680 nH inductance, shielded construction, surface mount configuration, and identical operating temperature ranges. The substitute offers improved current ratings and tighter inductance tolerance.

Q: What are the physical differences between these parts?

A: The substitute is physically smaller in length and width (2.00mm x 1.60mm vs. 2.00mm x 2.00mm) and has a lower seated height (1.00mm vs. 1.20mm). These differences may provide PCB layout advantages but require verification of available board space.

Q: Are there compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and rated for identical operating temperatures. Environmental and regulatory compliance is equivalent.

Q: Why does the substitute have higher DC resistance?

A: The VLS201610CX-R68M-1 has 76 mOhm maximum DC resistance compared to 66 mOhm for the original part. This 10 mOhm difference is within acceptable engineering margins for most applications and is offset by the superior current handling capacity and tighter inductance tolerance of the substitute.

Q: Is the substitute suitable for new designs?

A: Yes. The VLS201610CX-R68M-1 is classified as Active and is appropriate for new designs, unlike the original VLS2012ET-R68N which is Not For New Designs.
