Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS2012ET-2R2M is determined by the following critical parameters:

• Inductance Value: Must be 2.2 µH with ±20% tolerance to maintain circuit performance
• Current Rating: Minimum 1 A to support the original design current requirements
• DC Resistance: Must not exceed 153mOhm to preserve power dissipation characteristics
• Shielding: Must be shielded to maintain electromagnetic compatibility
• Operating Temperature: Must support -40°C ~ 105°C range
• Mounting Type: Must be Surface Mount compatible
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part VLS201610CX-2R2M-1 meets all these criteria while offering improved specifications in current rating and saturation current, with an active product status enabling continued availability.

Parameter Comparison

Engineering Selection Recommendations

The VLS201610CX-2R2M-1 is the qualified substitute for the VLS2012ET-2R2M based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical inductance values (2.2 µH) and tolerance specifications (±20%). The substitute provides higher current rating (1.53 A vs. 1 A) and improved saturation current (1.31 A vs. 1 A), offering enhanced performance margin for the original design specification.

Compliance and Certification: Both components are ROHS3 compliant with MSL 1 rating, ensuring regulatory and environmental compatibility. Both maintain REACH Unaffected status and EAR99 ECCN classification.

Product Status: The substitute part carries Active product status, ensuring long-term availability and supply chain stability, whereas the original part is designated "Not For New Designs," indicating end-of-life status.

Physical Compatibility: The substitute features a more compact footprint (2.00mm x 1.60mm vs. 2.00mm x 2.00mm) with reduced height (1.00mm vs. 1.20mm), providing layout flexibility while maintaining surface mount compatibility.

Frequently Asked Questions (FAQ)

Q: Can VLS201610CX-2R2M-1 be used as a direct replacement for VLS2012ET-2R2M?

A: Yes. Both parts share identical inductance (2.2 µH), tolerance (±20%), operating temperature range (-40°C ~ 105°C), shielding, and compliance certifications. The substitute meets or exceeds all electrical requirements of the original part.

Q: What are the differences in DC resistance between these parts?

A: The VLS2012ET-2R2M has 153mOhm maximum DCR, while the VLS201610CX-2R2M-1 has 163mOhm maximum DCR. This 10mOhm difference represents approximately 6.5% increase in resistance and should be evaluated for power dissipation-sensitive applications.

Q: Are there physical footprint considerations for PCB layout?

A: Yes. The substitute part is physically smaller (2.00mm x 1.60mm vs. 2.00mm x 2.00mm) with lower profile (1.00mm vs. 1.20mm). Existing PCB layouts designed for the original part will accommodate the substitute without modification, though the reduced footprint may allow for optimized board density in new designs.

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

A: This designation indicates the VLS2012ET-2R2M has reached end-of-life status in TDK's product portfolio. The VLS201610CX-2R2M-1 represents the active successor product with improved specifications and guaranteed long-term availability.

Q: What is the difference between the core materials?

A: The original part does not specify core material, while the substitute uses a ferrite drum core construction. Both maintain shielded wirewound inductor classification and identical electrical performance at the specified test frequency (1 MHz).
