Substitute Part Grouping Explanation

Substitution eligibility for the VLP6045LT-150M is determined by the following critical parameters:

• Inductance Value: Must be 15 µH with ±20% tolerance
• Shielding Type: Must be shielded to maintain electromagnetic isolation
• Core Material: Must be ferrite drum core wirewound construction
• Current Rating: Must support minimum 2.3 A continuous current
• DC Resistance: Lower or equal DCR values are acceptable; higher values may increase power dissipation
• Saturation Current (Isat): Must meet or exceed 2.5 A minimum
• Mounting Type: Must be surface mount compatible
• Operating Temperature Range: Must cover -40°C to 105°C
• Package Form Factor: Physical dimensions and height constraints must be compatible with board layout

The VLS6045EX-150M meets all substitution criteria and is classified as an active product with improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The VLS6045EX-150M is the direct substitute for the obsolete VLP6045LT-150M. Selection is based on the following factors:

Product Status: The VLS6045EX-150M is an active product with confirmed ongoing manufacturing and supply availability, whereas the VLP6045LT-150M is obsolete.

Electrical Performance: The VLS6045EX-150M provides superior electrical characteristics with a lower DC resistance of 75 mOhm compared to 112 mOhm maximum, resulting in reduced power dissipation. The higher saturation current rating of 3.1 A versus 2.5 A provides additional design margin.

Compliance: The VLS6045EX-150M is RoHS3 compliant, whereas compliance information for the VLP6045LT-150M is not provided. Both parts are REACH unaffected and classified as EAR99.

Physical Compatibility: The VLS6045EX-150M has a smaller footprint (6.00mm x 6.00mm versus 6.80mm x 6.80mm) while maintaining the same maximum height of 4.50mm, allowing for improved board layout density.

Functional Equivalence: Both inductors share identical inductance values, tolerance, shielding type, core material, mounting type, and operating temperature range, ensuring direct functional substitution.

Frequently Asked Questions (FAQ)

Q: Can the VLS6045EX-150M be used as a direct replacement for the VLP6045LT-150M?

A: Yes. Both parts have identical inductance values (15 µH ±20%), shielding configuration, core material, mounting type, and operating temperature range. The VLS6045EX-150M meets all electrical requirements of the VLP6045LT-150M with improved performance characteristics.

Q: What are the key differences between these two inductors?

A: The VLS6045EX-150M offers lower DC resistance (75 mOhm versus 112 mOhm maximum), higher current rating (2.5 A versus 2.3 A), higher saturation current (3.1 A versus 2.5 A), and a smaller footprint (6.00mm x 6.00mm versus 6.80mm x 6.80mm). The VLS6045EX-150M is an active product with RoHS3 compliance.

Q: Are there any package or mounting differences?

A: Both parts are surface mount components with identical maximum height (4.50mm). The VLS6045EX-150M has a smaller planar footprint, which may require PCB layout adjustment but maintains full mechanical compatibility with standard SMD assembly processes.

Q: What is the impact of the lower DC resistance in the VLS6045EX-150M?

A: Lower DC resistance reduces resistive power loss in the inductor, resulting in lower operating temperature and improved efficiency. This is a beneficial characteristic for applications with sustained current flow.

Q: Is the VLS6045EX-150M suitable for all applications using the VLP6045LT-150M?

A: The VLS6045EX-150M is suitable for applications where the VLP6045LT-150M was used, provided that the smaller physical footprint can be accommodated in the PCB layout. The improved electrical performance makes it compatible with or superior to the original design requirements.
