Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLS2010ET-100M is determined by the following critical parameters:

• Inductance Value: Must remain 10 µH with ±20% tolerance to maintain circuit performance
• Current Rating: Substitute must support minimum 470 mA continuous current
• DC Resistance: Lower or equal DCR values are acceptable; higher values may impact circuit efficiency
• Shielding: Shielded construction is required to maintain electromagnetic compatibility
• Surface Mount Configuration: Mounting type and footprint compatibility must be verified
• Operating Temperature Range: Must support -40°C to 105°C minimum
• Compliance Standards: RoHS3 compliance and MSL 1 rating required

The VLS201610CX-100M-1 qualifies as a direct substitute based on matching inductance, shielding, temperature range, and compliance certifications while offering improved current handling capability and lower DC resistance.

Parameter Comparison

Engineering Selection Recommendations

The VLS201610CX-100M-1 is the qualified substitute for the VLS2010ET-100M based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical inductance values and tolerance specifications. The substitute provides superior current handling (710 mA vs. 470 mA) and reduced DC resistance (732 mOhm vs. 936 mOhm), resulting in lower power dissipation and improved thermal performance in the application.

Physical Compatibility: The substitute maintains the same mounting type and seated height (1.00mm). The width dimension is reduced from 2.00mm to 1.60mm, which may provide layout advantages in space-constrained applications. PCB footprint verification is required prior to implementation.

Compliance and Longevity: The substitute carries Active product status from TDK Corporation, ensuring continued availability and supply chain stability. Both components maintain ROHS3 compliance and MSL 1 ratings, meeting environmental and moisture sensitivity requirements.

Thermal Performance: Operating temperature range remains -40°C to 105°C for both components. The substitute's lower DCR reduces self-heating, supporting extended operational life in thermally demanding environments.

Frequently Asked Questions (FAQ)

Q: Can the VLS201610CX-100M-1 be used as a direct replacement for the VLS2010ET-100M?

A: Yes, the VLS201610CX-100M-1 qualifies as a direct substitute. Both components share identical inductance values, tolerance specifications, shielding characteristics, and operating temperature ranges. The substitute offers improved electrical performance with higher current rating and lower DC resistance. PCB footprint compatibility must be verified due to the width dimension change from 2.00mm to 1.60mm.

Q: What are the key differences between these two inductors?

A: The primary differences are product status, current rating, and DC resistance. The VLS2010ET-100M is classified as "Not For New Designs," while the VLS201610CX-100M-1 is Active. The substitute supports 710 mA versus 470 mA and features 732 mOhm maximum DCR compared to 936 mOhm, resulting in lower power dissipation and improved thermal characteristics.

Q: Are there any package or footprint compatibility concerns?

A: The substitute has a slightly narrower width (1.60mm vs. 2.00mm) while maintaining the same length (2.00mm) and height (1.00mm). Both use surface mount technology with identical seated height. PCB layout verification is necessary to confirm that the reduced width does not create placement conflicts or require design modifications.

Q: Do both components meet the same compliance standards?

A: Yes, both the VLS2010ET-100M and VLS201610CX-100M-1 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. Both are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8504.50.4000.

Q: Why should I consider switching to the VLS201610CX-100M-1?

A: The substitute offers superior electrical performance with 51% higher current rating and 22% lower DC resistance, reducing power dissipation and heat generation. Its Active product status ensures long-term availability and supply chain continuity, whereas the original part is marked "Not For New Designs" and subject to potential discontinuation.
