Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLP6045LT-100M is determined by the following critical parameters:

• Inductance Value: Must be 10 µH with ±20% tolerance
• Current Rating: Must meet or exceed 3 A continuous current capability
• Saturation Current (Isat): Must meet or exceed 3.2 A
• DC Resistance (DCR): Lower or equal values are acceptable; higher values may impact circuit performance
• Core Type & Shielding: Must maintain ferrite core construction with shielding to preserve electromagnetic characteristics
• Operating Temperature Range: Must support -40°C to 105°C minimum
• Mounting Type: Must be surface mount compatible
• Physical Dimensions: Footprint compatibility is required for direct board-level substitution

The VLS6045EX-100M qualifies as a direct substitute based on these parameters. It maintains identical inductance, tolerance, core material, shielding, temperature range, and mounting type while offering improved electrical performance through higher current rating (3.4 A vs. 3 A) and lower DC resistance (47 mOhm vs. 72 mOhm).

Parameter Comparison

Engineering Selection Recommendations

The VLS6045EX-100M is the recommended substitute for the obsolete VLP6045LT-100M based on the following factors:

Product Status: The VLP6045LT-100M is classified as obsolete, making continued sourcing problematic. The VLS6045EX-100M carries active product status with substantial inventory availability (261,825 pcs), ensuring reliable supply chain access.

Electrical Compatibility: The substitute part maintains identical inductance value (10 µH) and tolerance (±20%), with superior electrical performance. The increased current rating (3.4 A vs. 3 A) and higher saturation current (3.9 A vs. 3.2 A) provide design margin. The reduced DC resistance (47 mOhm vs. 72 mOhm) decreases power dissipation and improves circuit efficiency.

Regulatory Compliance: The VLS6045EX-100M is ROHS3 compliant, meeting current environmental standards. Both parts maintain REACH unaffected status and identical moisture sensitivity levels (MSL 1).

Physical Compatibility: While the VLS6045EX-100M has a slightly smaller footprint (6.00mm x 6.00mm vs. 6.80mm x 6.80mm), both parts maintain identical maximum seated height (4.50mm) and surface mount mounting type, supporting direct board-level substitution with potential PCB layout optimization.

Frequently Asked Questions (FAQ)

Q: Can the VLS6045EX-100M directly replace the VLP6045LT-100M on existing PCBs?

A: Yes. Both inductors share identical inductance value, tolerance, operating temperature range, and maximum seated height. The VLS6045EX-100M has a smaller footprint (6.00mm vs. 6.80mm), which is compatible with existing pad layouts designed for the larger VLP6045LT-100M.

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

A: The VLS6045EX-100M provides improved performance with higher current rating (3.4 A vs. 3 A), higher saturation current (3.9 A vs. 3.2 A), and lower DC resistance (47 mOhm vs. 72 mOhm). These differences result in reduced power loss and increased current handling capability.

Q: Is the VLS6045EX-100M suitable for applications originally designed for the VLP6045LT-100M?

A: Yes. The substitute part meets or exceeds all critical electrical parameters of the original design. The lower DC resistance and higher current ratings provide equivalent or superior performance for the specified 10 µH inductance requirement.

Q: What is the significance of the product status change from obsolete to active?

A: Active product status indicates ongoing manufacturing and support from TDK Corporation. This ensures long-term availability, consistent quality, and access to technical documentation. The VLP6045LT-100M's obsolete status creates supply chain risk and limits future sourcing options.

Q: Are there any compliance or certification differences?

A: The VLS6045EX-100M is ROHS3 compliant, meeting current environmental regulations. Both parts maintain identical REACH unaffected status and moisture sensitivity levels, ensuring equivalent handling and storage requirements.

Q: How does the smaller physical size of the VLS6045EX-100M affect board design?

A: The reduced footprint (6.00mm x 6.00mm vs. 6.80mm x 6.80mm) allows for more compact PCB layouts while maintaining identical height and mounting compatibility. Existing pad patterns designed for the larger VLP6045LT-100M will accommodate the smaller substitute without modification.
