Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLS2010ET-220M is determined by the following critical parameters:

• Inductance Value: Must remain 22 µH with ±20% tolerance
• Shielding Requirement: Must be shielded to maintain electromagnetic isolation
• Mounting Type: Must be surface mount compatible
• Operating Temperature Range: Must support -40°C ~ 105°C minimum
• Current Handling: Substitute must support the application's current requirements
• DC Resistance: Lower DCR values indicate improved efficiency and reduced power dissipation
• RoHS and Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The VLS201610CX-220M-1 qualifies as a substitute based on matching inductance, shielding, temperature range, and compliance requirements while offering improved electrical performance characteristics.

Engineering Selection Recommendations

The VLS201610CX-220M-1 is the designated substitute for the VLS2010ET-220M based on the following engineering criteria:

Compliance and Status: The substitute part carries Active product status, making it suitable for new designs and ongoing production, whereas the main part is designated Not For New Designs. Both parts maintain ROHS3 compliance and REACH unaffected status.

Electrical Performance: The substitute delivers superior electrical characteristics with a maximum DC resistance of 1.582Ohm compared to 2.04Ohm in the main part, resulting in reduced power dissipation. The current rating increases from 330 mA to 480 mA, providing additional design margin for applications requiring higher current handling.

Functional Equivalence: Both parts maintain identical inductance values of 22 µH at ±20% tolerance and operate across the same temperature range of -40°C ~ 105°C. Shielding is preserved in both designs, ensuring equivalent electromagnetic performance.

Physical Compatibility: While package dimensions differ slightly (2.00mm x 1.60mm for the substitute versus 2.00mm x 2.00mm for the main part), both maintain the same maximum seated height of 1.00mm and surface mount mounting type, allowing for PCB layout adaptation.

Frequently Asked Questions (FAQ)

Q: Can the VLS201610CX-220M-1 directly replace the VLS2010ET-220M without circuit redesign?

A: The substitute maintains identical inductance value and tolerance, operating temperature range, and shielding characteristics. The improved DC resistance and higher current rating provide enhanced performance margins. Physical footprint dimensions differ slightly, requiring PCB layout verification.

Q: What is the significance of the "Not For New Designs" status on the main part?

A: This designation indicates the VLS2010ET-220M is in mature or end-of-life phase. The VLS201610CX-220M-1 carries Active status, making it the recommended choice for new product development and long-term supply continuity.

Q: How does the change from standard wirewound to drum core wirewound construction affect performance?

A: Both designs are shielded wirewound inductors meeting the same electrical specifications. The drum core construction in the substitute contributes to the improved DC resistance and current rating while maintaining functional equivalence.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both components, indicating no special handling requirements during storage or assembly.

Q: What should be considered when updating from the main part to the substitute in existing designs?

A: Verify PCB footprint compatibility given the dimensional differences. Confirm that the improved electrical characteristics (lower DCR, higher current rating) do not introduce unintended circuit behavior. Both parts operate identically within the specified inductance and temperature parameters.
