Substitute Part Grouping Explanation

Substitution eligibility for the VLS252015T-2R2M1R2 is determined by the following critical parameters:

Inductance value: 2.2 µH (exact match required)
Tolerance: ±20% (exact match required)
Shielding: Shielded (exact match required)
Package / Case: 1008 (2520 Metric) or equivalent footprint
Operating Temperature: -40°C ~ 105°C (minimum requirement)
RoHS Status: ROHS3 Compliant (exact match required)
Current Rating: Minimum 1.2 A
DC Resistance: Maximum 160mOhm

The substitute parts listed below meet these electrical and mechanical criteria and are therefore functionally equivalent for applications requiring the VLS252015T-2R2M1R2.

Engineering Selection Recommendations

For applications currently using the VLS252015T-2R2M1R2, the following selection criteria apply:

VLS252015ET-2R2M is a direct substitute with equivalent electrical specifications. This part maintains the same inductance, tolerance, DC resistance, and package dimensions. However, it carries a "Not For New Designs" status, making it suitable only for legacy system maintenance or replacement scenarios where design changes are not feasible.

VLS252010CX-2R2M-1 is the recommended alternative for new designs and ongoing production. This part is classified as Active and meets all critical electrical parameters: 2.2 µH inductance, ±20% tolerance, shielded construction, and ROHS3 compliance. It provides superior performance characteristics with a higher current rating (1.58 A versus 1.2 A) and lower DC resistance (126mOhm Max versus 160mOhm Max). The part is supplied in Tape & Reel packaging and maintains identical physical dimensions and operating temperature range. The nonstandard package designation does not affect mechanical compatibility with the 2520 footprint.

Frequently Asked Questions (FAQ)

Q: Can VLS252015ET-2R2M be used as a direct replacement for VLS252015T-2R2M1R2?

A: Yes. Both parts share identical inductance (2.2 µH), tolerance (±20%), DC resistance (160mOhm Max), shielding, package dimensions, and operating temperature range. The primary difference is the core material construction (Drum Core versus standard wirewound) and product status classification.

Q: Is VLS252010CX-2R2M-1 compatible with existing PCB designs for VLS252015T-2R2M1R2?

A: Yes. The VLS252010CX-2R2M-1 maintains identical physical dimensions (0.098" L x 0.079" W, 2.50mm x 2.00mm) and height (0.039" / 1.00mm), ensuring mechanical compatibility with existing 2520 footprints. Electrical compatibility is confirmed through matching inductance, tolerance, and shielding specifications.

Q: What are the key differences between the substitute parts?

A: VLS252015ET-2R2M is electrically equivalent but carries "Not For New Designs" status. VLS252010CX-2R2M-1 is the active production alternative with improved current rating (1.58 A) and lower DC resistance (126mOhm Max), making it the preferred choice for new designs and long-term availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant certification, matching the compliance status of the original VLS252015T-2R2M1R2.

Q: What is the significance of the "Nonstandard" package designation for VLS252010CX-2R2M-1?

A: The "Nonstandard" package designation refers to the internal package classification system. The supplier device package is listed as 2520, which corresponds to the standard 1008 (2520 Metric) footprint. This designation does not affect PCB compatibility or mechanical fit.
