Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS2012ET-150M is determined by the following critical parameters:

• Inductance Value: Must be 15 µH with ±20% tolerance to maintain circuit functionality
• Shielding Configuration: Must be shielded to preserve electromagnetic isolation properties
• Mounting Technology: Must be surface mount compatible
• Operating Temperature Range: Must support -40°C ~ 105°C minimum
• Compliance Standards: Must maintain ROHS3 compliance and REACH unaffected status

The VLS201610CX-150M-1 qualifies as a direct substitute based on matching inductance, shielding, mounting type, temperature range, and regulatory compliance. While the substitute exhibits higher current rating (540 mA vs. 400 mA) and slightly elevated DC resistance (1.258Ohm vs. 1.062Ohm), these parameters remain within acceptable substitution boundaries for applications operating at or below the original 400 mA specification.

Engineering Selection Recommendations

The VLS201610CX-150M-1 is the designated manufacturer-recommended substitute for the VLS2012ET-150M. Selection of this alternative part is supported by the following factors:

• Product Status Alignment: The substitute maintains Active status, ensuring continued availability and manufacturing support, whereas the original part is classified as Not For New Designs
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and safety requirements
• Functional Equivalence: Matching inductance value, tolerance, shielding, and operating temperature range ensure circuit-level compatibility
• Current Margin: The substitute's 540 mA rating provides operational headroom for applications designed around the original 400 mA specification
• Moisture Sensitivity: Both parts share MSL 1 classification, indicating no moisture sensitivity constraints during storage and handling

Frequently Asked Questions (FAQ)

Q: Can the VLS201610CX-150M-1 be used as a direct replacement in existing designs using the VLS2012ET-150M?

A: Yes. Both parts share identical inductance (15 µH), tolerance (±20%), shielding configuration, operating temperature range (-40°C ~ 105°C), and regulatory compliance status. The substitute is rated for higher current (540 mA vs. 400 mA), providing additional margin for applications operating at the original specification.

Q: What is the impact of the increased DC resistance in the substitute part?

A: The VLS201610CX-150M-1 exhibits 1.258Ohm maximum DC resistance compared to 1.062Ohm in the original part. This 0.196Ohm increase represents approximately 18.5% higher resistance. Circuit designers must evaluate power dissipation impact in applications sensitive to resistive losses.

Q: Are there physical dimension differences between these parts?

A: Yes. The VLS2012ET-150M measures 0.079" L x 0.079" W (2.00mm x 2.00mm) with 0.047" maximum seated height. The VLS201610CX-150M-1 measures 0.079" L x 0.063" W (2.00mm x 1.60mm) with 0.039" maximum seated height. Both use nonstandard packaging; PCB layout verification is required before substitution.

Q: Do both parts require identical handling and storage procedures?

A: Yes. Both parts share MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints. Standard surface mount component handling procedures apply to both parts.

Q: What certifications apply to the substitute part?

A: The VLS201610CX-150M-1 maintains ROHS3 compliance and REACH unaffected status, matching the original part's regulatory standing.
