Substitute Part Grouping Explanation

The VLS201610CX-100M-1 qualifies as a substitute for the VLS2012ET-100M based on the following critical parameters:

Matching Parameters:

• Inductance: 10 µH (identical)
• Inductance Tolerance: ±20% (identical)
• Shielding: Shielded (identical)
• Operating Temperature Range: -40°C ~ 105°C (identical)
• Mounting Type: Surface Mount (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Allowable Variations:

• Current Rating: 710 mA (higher than 470 mA requirement)
• DC Resistance: 732 mOhm Max (lower than 834 mOhm maximum)
• Physical Dimensions: 0.079" L x 0.063" W (2.00mm x 1.60mm) vs. 0.079" L x 0.079" W (2.00mm x 2.00mm)
• Height: 0.039" (1.00mm) vs. 0.047" (1.20mm)
• Core Material: Ferrite drum core vs. unspecified core material

The substitute part provides superior electrical performance with higher current capacity and lower DC resistance, while maintaining the same inductance value and operating specifications. Physical dimensions are slightly reduced, which may require PCB layout verification.

Parameter Comparison

Engineering Selection Recommendations

The VLS201610CX-100M-1 is the recommended substitute for the VLS2012ET-100M. Both components are manufactured by TDK Corporation and maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected). The substitute part carries Active product status, ensuring long-term availability and supply chain continuity.

The VLS201610CX-100M-1 provides enhanced electrical performance with 710 mA current rating capacity versus the original 470 mA specification, and reduced DC resistance of 732 mOhm compared to 834 mOhm. These improvements result in lower power dissipation and thermal stress in the application circuit.

Physical footprint differences require PCB layout evaluation. The substitute part is narrower (1.60mm vs. 2.00mm width) and shorter (1.00mm vs. 1.20mm height), which may provide space optimization benefits or require minor layout adjustments depending on existing design constraints.

Frequently Asked Questions (FAQ)

Q: Can the VLS201610CX-100M-1 directly replace the VLS2012ET-100M in existing designs?

A: Yes, from an electrical standpoint. Both components share identical inductance (10 µH), tolerance (±20%), operating temperature range (-40°C ~ 105°C), and shielding characteristics. The substitute part offers superior current handling (710 mA vs. 470 mA) and lower DC resistance (732 mOhm vs. 834 mOhm). PCB layout verification is required due to reduced physical dimensions.

Q: What are the physical dimension differences?

A: The VLS201610CX-100M-1 measures 2.00mm L x 1.60mm W x 1.00mm H (seated), compared to the VLS2012ET-100M at 2.00mm L x 2.00mm W x 1.20mm H. The substitute is narrower and shorter, which may affect PCB routing and component placement.

Q: Are both parts RoHS compliant?

A: Yes. Both the VLS2012ET-100M and VLS201610CX-100M-1 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

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

A: The VLS2012ET-100M has been superseded by TDK Corporation. The VLS201610CX-100M-1 represents the active product line equivalent with improved specifications and guaranteed long-term availability.

Q: What is the difference in DC resistance impact?

A: The substitute part has 102 mOhm lower maximum DC resistance (732 mOhm vs. 834 mOhm). This results in reduced power dissipation and heat generation at rated current, improving overall circuit efficiency and component reliability.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both components have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during storage, transport, or assembly.
