Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS2010ET-150M is determined by the following critical parameters:

• Inductance Value: Must match 15 µH with ±20% tolerance
• Current Rating: Must meet or exceed 400 mA continuous current requirement
• Saturation Current (Isat): Must support minimum 400 mA saturation threshold
• DC Resistance (DCR): Lower or equal resistance values are acceptable; higher values may impact circuit performance
• Shielding: Must maintain shielded construction to prevent electromagnetic interference
• Operating Temperature: Must cover the -40°C ~ 105°C range
• Surface Mount Compatibility: Must be compatible with surface mount assembly processes
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The VLS201610CX-150M-1 qualifies as a direct substitute based on matching inductance, shielding, temperature range, compliance certifications, and exceeding the current and saturation current requirements while maintaining lower DC resistance.

Parameter Comparison

Engineering Selection Recommendations

The VLS201610CX-150M-1 is the qualified substitute for the VLS2010ET-150M based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical 15 µH inductance with ±20% tolerance and operate across the same -40°C ~ 105°C temperature range. The substitute provides superior current handling with 540 mA rating versus 400 mA, and higher saturation current of 440 mA. The substitute's lower DC resistance of 1.258Ohm Max compared to 1.476Ohm Max reduces resistive losses in the circuit.

Compliance and Certification: Both components are ROHS3 compliant with MSL 1 rating, ensuring equivalent environmental and moisture handling requirements.

Product Status: The substitute carries Active product status, making it suitable for new designs and ongoing production, whereas the main part is designated "Not For New Designs."

Physical Compatibility: The substitute maintains the same height (1.00mm) and length (2.00mm) but has a reduced width of 1.60mm compared to 2.00mm. PCB layout verification is required to confirm footprint compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the VLS201610CX-150M-1 be used as a direct replacement for the VLS2010ET-150M?

A: Yes, the VLS201610CX-150M-1 qualifies as a substitute based on matching inductance value, tolerance, shielding, temperature range, and compliance certifications. However, the reduced package width (1.60mm vs 2.00mm) requires PCB layout verification to ensure physical compatibility with existing footprints.

Q: What are the key electrical advantages of the substitute part?

A: The VLS201610CX-150M-1 provides higher current rating (540 mA vs 400 mA), higher saturation current (440 mA vs 400 mA), and lower DC resistance (1.258Ohm vs 1.476Ohm), resulting in improved thermal performance and reduced power dissipation.

Q: Are there any compliance differences between the two parts?

A: No. Both parts maintain identical ROHS3 compliance, MSL 1 rating, and REACH unaffected status. Compliance requirements are equivalent.

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

A: The VLS2010ET-150M carries this designation, indicating it is being phased out. The VLS201610CX-150M-1 with Active status is the recommended alternative for new design initiatives and ongoing production.

Q: What should be verified before implementing the substitute in production?

A: PCB layout compatibility must be confirmed due to the package width reduction from 2.00mm to 1.60mm. Electrical performance remains equivalent across all specified parameters.
