Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLS252015ET-4R7M is determined by the following critical parameters:

Inductance Value: 4.7 µH (fixed requirement)

Core Material & Shielding: Ferrite material with shielding (electromagnetic containment requirement)

Package Dimensions: 1008 (2520 Metric) footprint with 2.50mm × 2.00mm × 1.00mm maximum height (PCB layout compatibility)

Current Handling: Minimum 890 mA rating required for equivalent operation

DC Resistance: Maximum 318 mOhm acceptable for thermal and efficiency performance

Temperature Range: -40°C to 105°C operating specification

Compliance: ROHS3 compliance and MSL Level 1 rating

The identified substitute part VLS252010CX-4R7M-1 maintains the same inductance value, core material, shielding configuration, and package footprint while offering improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The VLS252010CX-4R7M-1 serves as a direct substitute for the VLS252015ET-4R7M based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical inductance values (4.7 µH) and tolerance specifications (±20%). The substitute offers superior current handling capacity (1.11 A versus 890 mA) and reduced DC resistance (235 mOhm versus 318 mOhm maximum), providing enhanced thermal performance and lower power dissipation in equivalent circuit applications.

Physical Compatibility: Identical footprint dimensions (2.50mm × 2.00mm) and maximum seated height (1.00mm) ensure direct PCB layout compatibility without redesign requirements.

Compliance Status: Both components maintain ROHS3 compliance, MSL Level 1 rating, and identical operating temperature ranges (-40°C to 105°C), satisfying regulatory and environmental requirements.

Product Lifecycle: The substitute part carries an "Active" product status, ensuring long-term availability and supply chain continuity compared to the "Not For New Designs" status of the original part.

Frequently Asked Questions (FAQ)

Q: Can VLS252010CX-4R7M-1 be used as a direct replacement for VLS252015ET-4R7M?

A: Yes. Both parts share identical inductance values (4.7 µH), core material (ferrite shielded drum core), package footprint (1008/2520 Metric), and operating temperature range (-40°C to 105°C). The substitute offers improved electrical performance with higher current rating and lower DC resistance.

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

A: The primary differences are current rating (1.11 A versus 890 mA), DC resistance (235 mOhm versus 318 mOhm maximum), and product status (Active versus Not For New Designs). The substitute provides superior electrical performance characteristics within the same physical package.

Q: Are there any package compatibility concerns?

A: The substitute part is listed with a "Nonstandard" package designation in the formal classification, though the supplier device package is specified as 2520 with identical physical dimensions (2.50mm × 2.00mm × 1.00mm maximum height). PCB layout compatibility is maintained.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both components are ROHS3 compliant, carry MSL Level 1 rating, and maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99).

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

A: This designation indicates the part is in end-of-life status. The VLS252010CX-4R7M-1 substitute maintains active production status and is recommended for new design implementations and ongoing production requirements.
