Key Parameters

Substitute Part Grouping Explanation

The VLS252012ET-2R2M qualifies as a direct substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Inductance: 2.2 µH (identical)
• Tolerance: ±20% (identical)
• Core Material: Ferrite (identical)
• Shielding: Shielded (identical)
• Operating Temperature Range: -40°C to 105°C (identical)
• Mounting Type: Surface Mount (identical)

Enhanced Specifications:

• Current Rating: 1.3 A (exceeds 900 mA requirement)
• DC Resistance: 154 mOhm Max (lower than 175.5 mOhm maximum)
• Current Saturation: 1.55 A (higher margin)

The substitute part operates within the same electrical performance envelope while providing improved current handling capacity and reduced DC resistance, making it suitable for direct replacement in applications requiring the CPL2512T2R2M.

Parameter Comparison

Engineering Selection Recommendations

The VLS252012ET-2R2M is the manufacturer-recommended substitute for the obsolete CPL2512T2R2M. Selection of this substitute is based on:

• Electrical parameter equivalence across inductance, tolerance, core material, and shielding specifications
• Superior current handling capacity (1.3 A vs. 900 mA) providing design margin
• Reduced DC resistance (154 mOhm vs. 175.5 mOhm maximum) improving efficiency
• Identical operating temperature range ensuring thermal compatibility
• ROHS3 compliance of the substitute part meeting current regulatory requirements
• Availability of 1201 pieces in stock for production continuity

The substitute part transitions from a nonstandard package to the standardized 1008 (2520 Metric) package format, which may require PCB layout verification to confirm mechanical fit within the available footprint space.

Frequently Asked Questions (FAQ)

Q: Can the VLS252012ET-2R2M directly replace the CPL2512T2R2M in existing designs?

A: Yes, the VLS252012ET-2R2M meets all critical electrical specifications. However, the package transition from nonstandard to 1008 (2520 Metric) requires confirmation that the PCB footprint accommodates the substitute part's dimensions: 0.098" L x 0.079" W (2.50mm x 2.00mm) with a maximum seated height of 0.039" (1.00mm).

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

A: The substitute part provides higher current rating (1.3 A vs. 900 mA) and lower DC resistance (154 mOhm vs. 175.5 mOhm maximum). Both parts maintain identical inductance (2.2 µH), tolerance (±20%), and operating temperature range (-40°C to 105°C).

Q: Are there compliance differences between the main part and substitute?

A: The CPL2512T2R2M is classified as obsolete with no RoHS status specified. The VLS252012ET-2R2M is ROHS3 compliant and carries "Not For New Designs" status, indicating it is available for legacy system support but not recommended for new product development.

Q: What is the significance of the package change from nonstandard to 1008 (2520 Metric)?

A: The 1008 (2520 Metric) package is an industry-standard surface mount inductor format. This standardization improves long-term availability and reduces supply chain risk compared to the nonstandard package of the original part.

Q: How do the saturation current ratings compare?

A: The CPL2512T2R2M has a saturation current of 900 mA, while the VLS252012ET-2R2M provides 1.55 A saturation current. This higher saturation margin in the substitute part reduces the risk of inductance degradation under peak current conditions.
