Substitute Part Grouping Explanation

The VLS201610CX-220M-1 qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Inductance value: 22 µH (identical)
• Inductance tolerance: ±20% (identical)
• Shielding: Shielded (identical)
• Operating temperature range: -40°C to 105°C (identical)
• Inductance test frequency: 1 MHz (identical)
• RoHS3 compliance (identical)
• Moisture sensitivity level: 1 (Unlimited) (identical)
• Mounting type: Surface Mount (identical)

Improved Electrical Performance:

• Current rating: 480 mA (versus 330 mA in main part)
• DC resistance: 1.582 Ohm Max (lower than 1.764 Ohm in main part)

Physical Differences:

• Package footprint: 2.00mm x 1.60mm (versus 2.00mm x 2.00mm)
• Height: 0.039" (1.00mm) (versus 0.047" (1.20mm))
• Core type: Drum Core, Ferrite (versus unspecified core material)

The substitute part maintains all critical electrical specifications while offering enhanced current handling capability and reduced DC resistance. Physical dimensions differ slightly; PCB layout verification is required to confirm footprint compatibility.

Engineering Selection Recommendations

The VLS201610CX-220M-1 is the qualified substitute for the VLS2012ET-220M based on the following engineering criteria:

Compliance & Regulatory Status: Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with current manufacturing and environmental standards. The substitute part carries Active product status, confirming ongoing manufacturer support and availability.

Electrical Compatibility: The substitute part maintains the specified 22 µH inductance value and ±20% tolerance, ensuring circuit performance equivalence. The improved current rating (480 mA versus 330 mA) and reduced DC resistance (1.582 Ohm versus 1.764 Ohm) provide enhanced thermal performance and lower power dissipation in the application.

Physical Considerations: The substitute part features a smaller footprint (2.00mm x 1.60mm versus 2.00mm x 2.00mm) and reduced height (1.00mm versus 1.20mm). PCB layout verification is required to confirm that the modified dimensions are compatible with existing board designs and component placement constraints.

Frequently Asked Questions (FAQ)

Q: Can the VLS201610CX-220M-1 be used as a direct replacement for the VLS2012ET-220M?

A: The substitute part maintains identical inductance, tolerance, shielding, and operating temperature specifications. However, physical dimensions differ: the substitute is narrower (1.60mm versus 2.00mm width) and shorter (1.00mm versus 1.20mm height). PCB layout compatibility must be verified before implementation.

Q: What are the key electrical differences between these parts?

A: The substitute part offers improved electrical performance with a higher current rating (480 mA versus 330 mA) and lower DC resistance (1.582 Ohm versus 1.764 Ohm). These improvements reduce power dissipation and thermal stress in the application circuit.

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

A: The VLS2012ET-220M has been transitioned out of active production by TDK Corporation. The VLS201610CX-220M-1 is the active equivalent, ensuring long-term component availability and manufacturer support for new designs.

Q: Are both parts RoHS compliant?

A: Yes, both the VLS2012ET-220M and VLS201610CX-220M-1 are ROHS3 compliant with unlimited moisture sensitivity (MSL 1), meeting current environmental and manufacturing standards.

Q: What should be verified before implementing the substitute part?

A: Confirm PCB footprint compatibility with the modified dimensions (2.00mm x 1.60mm footprint and 1.00mm maximum height). Verify that the reduced DC resistance and improved current rating do not introduce unintended circuit behavior changes.
