Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLS252008ET-2R2M-CA is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 2.2 µH (exact match required)
• Core type: Ferrite drum core, shielded construction
• Mounting: Surface mount technology
• Environmental compliance: ROHS3 and REACH requirements

Secondary Compatibility Factors:

• Current rating must meet or exceed the application requirement (minimum 840 mA for direct replacement)
• DC resistance characteristics must be compatible with circuit thermal and efficiency constraints
• Operating temperature range must encompass the application environment
• Saturation current must support transient conditions

The VLS6045EX-2R2N-H qualifies as a manufacturer-recommended substitute based on matching inductance value, core material, shielding configuration, and compliance certifications. This substitute provides enhanced electrical performance with higher current capacity (5.1 A vs. 840 mA) and lower DC resistance (24.7 mOhm vs. 290 mOhm), making it suitable for applications requiring improved thermal performance and current headroom.

Engineering Selection Recommendations

The VLS6045EX-2R2N-H is the manufacturer-designated substitute for the VLS252008ET-2R2M-CA. Selection of this alternative is supported by the following factors:

Product Status: The original part carries "Not For New Designs" designation, while the substitute maintains "Active" status with full manufacturing support and availability.

Compliance & Certifications: Both components meet ROHS3 and REACH requirements. The substitute includes AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

Electrical Performance: The substitute delivers superior electrical characteristics with 6× higher current rating and 11.7× lower DC resistance, enabling improved thermal performance and reduced power dissipation in the inductor element.

Temperature Range: The substitute extends the upper operating temperature limit from 105°C to 125°C, accommodating higher ambient or component-level thermal environments.

Physical Considerations: The substitute occupies a larger footprint (6.30mm × 6.00mm × 4.50mm vs. 2.50mm × 2.00mm × 0.80mm). PCB layout modifications are required to accommodate the increased package dimensions.

Frequently Asked Questions (FAQ)

Q: Can the VLS6045EX-2R2N-H be used as a direct drop-in replacement for the VLS252008ET-2R2M-CA?

A: Electrical substitution is valid based on matching inductance value and core characteristics. However, physical layout changes are mandatory due to the larger package footprint. PCB routing and component placement must be redesigned to accommodate the 6.30mm × 6.00mm × 4.50mm package dimensions.

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

A: The substitute provides significantly lower DC resistance (24.7 mOhm vs. 290 mOhm) and higher current capacity (5.1 A vs. 840 mA). These improvements reduce power dissipation and thermal stress, beneficial for high-current applications. The inductance tolerance widens from ±20% to ±30%, which may require circuit validation in precision-dependent applications.

Q: Are both parts suitable for automotive applications?

A: The original part carries no automotive qualification. The substitute includes AEC-Q200 certification, making it suitable for automotive-grade designs. If automotive compliance is required, the substitute is the appropriate selection.

Q: What is the impact of the extended temperature range on component selection?

A: The substitute supports operation to 125°C versus 105°C for the original part. This extended range accommodates higher ambient temperatures and provides thermal margin in thermally constrained applications. Applications operating below 105°C are compatible with either component from a temperature perspective.

Q: How does the inductance tolerance difference affect circuit design?

A: The original part specifies ±20% tolerance while the substitute specifies ±30%. Applications with tight inductance requirements may require circuit tuning or component selection to maintain performance specifications. Tolerance impact should be evaluated against circuit sensitivity to inductance variation.

Q: What inventory and lead time considerations apply to these parts?

A: The original part shows 2,253 pieces in stock with "Not For New Designs" status, indicating limited future availability. The substitute shows 8,010 pieces in stock with "Active" status, ensuring sustained supply for ongoing production and new designs.
