Engineering Selection Recommendations

VLS252012ET-2R2M: This part maintains identical inductance, current rating, and package specifications as the original VLS252012T-2R2M1R3. The DC resistance is marginally lower at 154mOhm, and saturation current is slightly reduced at 1.55 A. The part carries a "Not For New Designs" status, making it suitable for legacy system maintenance and repair applications where direct compatibility is required.

VLS252010CX-2R2M-1: This part is classified as Active and represents the recommended path forward for new designs. It maintains the 2.2 µH inductance and ±20% tolerance while offering improved performance characteristics: higher current rating at 1.58 A and lower DC resistance at 126mOhm. The package designation is listed as Nonstandard but maintains the 2520 footprint dimensions identical to the original part. All three parts are ROHS3 Compliant and operate within the same temperature range.

Frequently Asked Questions (FAQ)

Q: Can VLS252012ET-2R2M be used as a direct replacement for VLS252012T-2R2M1R3?

A: Yes. Both parts share identical inductance (2.2 µH), current rating (1.3 A), tolerance (±20%), package dimensions (1008/2520 Metric), and operating temperature range (-40°C ~ 105°C). DC resistance values are nearly equivalent (154mOhm vs 155mOhm). The primary difference is the core material specification and product status classification.

Q: Is VLS252010CX-2R2M-1 compatible with circuits designed for VLS252012T-2R2M1R3?

A: Functional compatibility exists based on matching inductance value (2.2 µH), tolerance (±20%), shielding (Shielded), and physical footprint (2520 dimensions). The VLS252010CX-2R2M-1 offers superior electrical performance with lower DC resistance (126mOhm vs 155mOhm) and higher current rating (1.58 A vs 1.3 A). The nonstandard package designation does not affect PCB footprint compatibility.

Q: What is the significance of the "Not For New Designs" status on VLS252012ET-2R2M?

A: This classification indicates the part is available for existing applications but TDK does not recommend its use in new product development. For new designs, VLS252010CX-2R2M-1 (Active status) is the preferred selection.

Q: Are all three parts RoHS compliant?

A: Yes. VLS252012T-2R2M1R3, VLS252012ET-2R2M, and VLS252010CX-2R2M-1 are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: How do DC resistance values affect circuit performance?

A: DC resistance directly impacts power dissipation and voltage drop across the inductor. VLS252010CX-2R2M-1 exhibits the lowest DCR at 126mOhm, resulting in reduced heat generation compared to the original part at 155mOhm. This characteristic makes it suitable for applications where thermal management is a consideration.
