Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLS252012ET-2R2M-CA are selected based on the following critical parameters:

Primary Matching Criteria:

• Inductance value: 2.2 µH (exact match required)
• Shielding: Shielded configuration
• Core type: Drum core, wirewound construction
• Surface mount technology

Secondary Compatibility Factors:

• Current rating must meet or exceed 1.3 A minimum requirement
• DC resistance should remain within acceptable limits for the application
• Package footprint compatibility or acceptable size variation
• Operating temperature range coverage of -40°C ~ 105°C minimum
• RoHS3 compliance and regulatory alignment

The identified substitutes maintain the core inductance specification and shielded drum core architecture while offering variations in current handling capacity, DC resistance, package dimensions, and product status.

Parameter Comparison

Engineering Selection Recommendations

VLS6045EX-2R2N-H (TDK Corporation): This substitute offers the highest current rating at 5.1 A with significantly reduced DC resistance of 24.7mOhm, providing superior thermal performance and lower power dissipation. The part carries Active product status and extended operating temperature range to 125°C. However, the nonstandard package dimensions (6.30mm x 6.00mm) and increased height (4.50mm) require PCB layout redesign and may not fit existing footprints. The ±30% inductance tolerance is wider than the main part. This substitute is suitable for applications requiring higher current capacity and long-term supply assurance.

MAKK2520T2R2M (Taiyo Yuden): This substitute maintains identical package dimensions and footprint compatibility with the main part (1008/2520 Metric), enabling direct PCB replacement without layout modification. Current rating of 1.5 A exceeds the main part's 1.3 A specification, and DC resistance of 156mOhm is comparable. The metal core construction differs from the ferrite core of the main part. Product status is Not For New Designs, matching the main part's lifecycle status. This substitute is optimal for applications requiring form-factor compatibility and minimal design changes.

Both substitutes maintain ROHS3 compliance, unlimited moisture sensitivity rating, and the required 2.2 µH inductance specification with shielded drum core construction.

Frequently Asked Questions (FAQ)

Q: Can VLS6045EX-2R2N-H be used as a direct replacement for VLS252012ET-2R2M-CA?

A: VLS6045EX-2R2N-H is electrically compatible as a substitute but requires PCB redesign. The nonstandard package dimensions (6.30mm x 6.00mm versus 2.50mm x 2.00mm) and increased height (4.50mm versus 1.20mm) mean the component cannot be placed in the existing footprint. Use this substitute only when PCB layout modification is feasible and the enhanced current rating (5.1 A) and reduced DC resistance (24.7mOhm) provide application benefits.

Q: Is MAKK2520T2R2M a drop-in replacement?

A: Yes, MAKK2520T2R2M maintains identical package dimensions and footprint (1008/2520 Metric), allowing direct PCB replacement without layout changes. The 1.5 A current rating exceeds the main part's 1.3 A specification, and DC resistance of 156mOhm is within acceptable tolerance. The metal core construction differs from the ferrite core but maintains shielded drum core functionality.

Q: What are the key differences between ferrite and metal core inductors?

A: The main part uses ferrite core material, while MAKK2520T2R2M uses metal core. Both are shielded drum core wirewound designs. Core material selection affects frequency response, saturation characteristics, and thermal behavior. Ferrite cores typically provide better high-frequency performance, while metal cores offer different saturation curves. Selection depends on specific circuit requirements.

Q: Why does VLS6045EX-2R2N-H have wider inductance tolerance (±30% vs ±20%)?

A: Inductance tolerance is determined by manufacturing process and core material specifications. The VLS6045EX-2R2N-H's ±30% tolerance reflects its design specifications. For applications requiring tighter inductance control, the ±20% tolerance of the main part or MAKK2520T2R2M may be preferred.

Q: Are all substitutes RoHS3 compliant?

A: Yes, all three parts (main part and both substitutes) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of "Not For New Designs" product status?

A: This status indicates the part has been superseded in the manufacturer's portfolio. While existing inventory remains available, the manufacturer recommends using active alternatives for new designs. Both VLS252012ET-2R2M-CA and MAKK2520T2R2M carry this status, while VLS6045EX-2R2N-H is Active and recommended for new applications.
