Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS2010ET-2R2M is determined by the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 2.2 µH
• Inductance tolerance: ±20%
• Shielding type: Shielded
• Mounting type: Surface Mount
• Operating temperature range: -40°C ~ 105°C or wider
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current rating: Must meet or exceed 1 A minimum
• DC resistance: Lower values are acceptable (improved performance)
• Core material: Wirewound construction with ferrite or equivalent core materials
• Package dimensions: Nonstandard packages with compatible footprints
• Product status: Active status preferred for long-term availability

The VLS201610CX-2R2M-1 qualifies as a direct substitute based on matching inductance, tolerance, shielding, mounting type, temperature range, and RoHS compliance, while offering improved current handling and reduced DC resistance.

Parameter Comparison

Engineering Selection Recommendations

The VLS201610CX-2R2M-1 is the qualified substitute for VLS2010ET-2R2M based on the following engineering criteria:

Compliance & Certification Alignment: Both parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility across applications.

Product Status Advantage: The substitute part carries Active product status, providing assurance of continued manufacturing and long-term supply availability, whereas the main part is designated Not For New Designs.

Performance Improvements: The substitute delivers enhanced electrical performance with 53% higher current rating (1.53 A vs. 1 A) and 28.5% lower DC resistance (163mOhm vs. 228mOhm), reducing thermal dissipation and improving efficiency in current-limited applications.

Mechanical Compatibility: Both parts share identical height (1.00mm maximum seated height) and mounting type (Surface Mount). The substitute footprint is slightly narrower (1.60mm vs. 1.60mm width), maintaining compatibility with existing PCB layouts designed for the original part.

Frequently Asked Questions (FAQ)

Q: Can VLS201610CX-2R2M-1 be used as a direct replacement for VLS2010ET-2R2M?

A: Yes. Both parts maintain identical inductance (2.2 µH), tolerance (±20%), shielding, mounting type, and operating temperature range. The substitute meets all functional requirements while offering improved current handling and reduced DC resistance.

Q: What are the key differences between these parts?

A: The substitute features a drum core construction versus standard wirewound, delivers higher current rating (1.53 A vs. 1 A), lower DC resistance (163mOhm vs. 228mOhm), and carries Active product status for continued availability. Physical dimensions are nearly identical with compatible mounting heights.

Q: Are there any package or footprint concerns?

A: Both parts are surface mount with matching 1.00mm maximum seated height. The substitute width is 1.60mm compared to 1.60mm for the original, ensuring PCB layout compatibility. Verify specific footprint requirements for your application.

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

A: This designation indicates TDK has superseded this component in their active product line. The VLS201610CX-2R2M-1 represents the current recommended alternative with improved specifications and guaranteed long-term supply.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity rating, meeting identical regulatory and environmental standards.
