VLS2010ET-2R2M-CA Equivalent & Substitute Parts

Part Overview

The VLS2010ET-2R2M-CA is a 2.2 µH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 1.05 A continuous current with a maximum DC resistance of 228mOhm. This component is designed for surface mount applications in compact form factors and operates across the industrial temperature range of -40°C to 105°C.

The VLS2010ET-2R2M-CA carries a "Not For New Designs" product status, indicating that TDK has discontinued active development and support for this series. Organizations requiring this inductance value and current rating for new or ongoing production must evaluate qualified substitute components to ensure long-term supply chain stability and access to active manufacturer support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLS2010ET-2R2M-CA is determined by the following critical parameters:

Primary Substitution Criteria:

• Inductance value: 2.2 µH (exact match required)
• Core type: Ferrite drum core, wirewound (functional equivalence)
• Shielding: Shielded construction (electromagnetic containment requirement)
• Mounting: Surface mount technology

Secondary Compatibility Parameters:

• Current rating must meet or exceed the application requirement of 1.05 A
• DC resistance must be acceptable for the circuit's thermal and efficiency constraints
• Operating temperature range must encompass the application environment
• RoHS and REACH compliance status must satisfy regulatory requirements

The VLS6045EX-2R2N-H qualifies as a manufacturer-recommended substitute based on matching inductance, core material, shielding type, and mounting technology. This substitute provides enhanced electrical performance characteristics including higher current capacity and lower DC resistance, with active product status and extended temperature range support.

Engineering Selection Recommendations

The VLS6045EX-2R2N-H is the manufacturer-recommended substitute for the VLS2010ET-2R2M-CA. Selection of this substitute is supported by the following engineering factors:

Product Status: The substitute maintains Active product status with ongoing manufacturer support, whereas the main part is designated "Not For New Designs." This distinction is critical for long-term supply chain reliability and technical support availability.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH Unaffected status, satisfying current environmental and hazardous substance regulations. The substitute extends the operating temperature range to 125°C, providing additional thermal margin for demanding applications.

Electrical Performance: The substitute delivers superior electrical characteristics with 5.1 A current rating and 24.7mOhm maximum DC resistance compared to the main part's 1.05 A and 228mOhm specifications. These improvements reduce thermal dissipation and provide operational headroom for circuit designs.

Physical Considerations: The substitute employs a larger package footprint (6.30mm x 6.00mm x 4.50mm) compared to the main part (2.00mm x 2.00mm x 1.00mm). PCB layout modifications are required to accommodate this dimensional change.

Frequently Asked Questions (FAQ)

Q: Can the VLS6045EX-2R2N-H be used as a direct replacement without circuit modifications?

A: The substitute maintains the same 2.2 µH inductance value, ferrite core material, and shielded construction. However, the larger package dimensions require PCB layout changes. Electrical performance improvements (lower DCR, higher current rating) are generally beneficial but must be evaluated within the specific circuit context.

Q: What is the significance of the inductance tolerance difference between the main part (±20%) and substitute (±30%)?

A: The main part specifies tighter tolerance (±20%), while the substitute allows ±30%. For applications requiring precise inductance values, tolerance stack-up analysis must be performed to confirm the substitute meets circuit specifications.

Q: Why is the DC resistance of the substitute significantly lower (24.7mOhm vs. 228mOhm)?

A: The substitute's larger physical dimensions and higher current rating enable use of larger gauge wire, resulting in substantially lower resistance. This reduces I²R losses and heat generation, improving overall circuit efficiency.

Q: Are there any temperature range considerations for substitution?

A: The main part operates to 105°C maximum, while the substitute extends to 125°C. Applications operating near the upper temperature limit of the main part benefit from the substitute's extended range. Conversely, applications with strict thermal budgets must account for the substitute's lower DCR, which may alter thermal characteristics.

Q: What compliance certifications apply to both components?

A: Both components are ROHS3 compliant and REACH Unaffected. The substitute additionally carries AEC-Q200 automotive qualification, providing enhanced reliability documentation for applications requiring automotive-grade components.
