Parameter Comparison

Engineering Selection Recommendations

VLS252012ET-100M is a direct substitute with identical electrical specifications (10 µH, ±20% tolerance, 590 mA rating, 756 mOhm DCR) and matching package footprint (1008 / 2520 Metric). This part carries ROHS3 compliance and MSL 1 rating identical to the original. The primary distinction is the increased seated height (1.20mm vs. 1.00mm), which requires PCB layout verification for clearance compatibility. Product status is Not For New Designs, indicating limited long-term availability.

VLS252010CX-100M-1 is the manufacturer-recommended substitute with Active product status, ensuring sustained supply chain availability. This part maintains the 10 µH inductance, ±20% tolerance, and identical operating temperature range. Key electrical improvements include higher current rating (710 mA vs. 590 mA) and lower DC resistance (580 mOhm vs. 756 mOhm). The package designation is listed as Nonstandard with supplier device package 2520, maintaining the same physical footprint (2.50mm x 2.00mm) and seated height (1.00mm) as the original. ROHS3 compliance and MSL 1 rating are maintained. This part is suitable for new designs and provides superior electrical performance characteristics.

For applications requiring immediate replacement with minimal design changes, VLS252012ET-100M provides direct electrical equivalence. For long-term production and new design implementations, VLS252010CX-100M-1 is the recommended selection due to Active status and improved electrical performance.

Frequently Asked Questions (FAQ)

Q: Can VLS252012ET-100M be used as a direct replacement for VLS252012T-100MR59?

A: Yes. Both parts share identical inductance (10 µH), tolerance (±20%), current rating (590 mA), and DC resistance (756 mOhm Max). The primary consideration is the increased seated height of VLS252012ET-100M (1.20mm vs. 1.00mm), which must be verified against PCB clearance requirements and component placement constraints.

Q: What is the advantage of VLS252010CX-100M-1 over the other substitutes?

A: VLS252010CX-100M-1 carries Active product status, ensuring long-term availability and supply chain continuity. It provides improved electrical performance with higher current rating (710 mA) and lower DC resistance (580 mOhm), reducing thermal dissipation in the application circuit. The seated height matches the original specification (1.00mm).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. VLS252012ET-100M and VLS252010CX-100M-1 are both ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental compliance profile.

Q: Does the package designation difference affect PCB compatibility?

A: The physical footprint dimensions (2.50mm x 2.00mm) remain consistent across all parts. VLS252010CX-100M-1 is designated as Nonstandard package with supplier device package 2520, but maintains the same land pattern and mounting compatibility as the standard 1008 (2520 Metric) designation. Verification with component placement data is recommended.

Q: What is the saturation current difference between substitute parts?

A: VLS252012T-100MR59 has Isat of 810 mA, VLS252012ET-100M has 730 mA, and VLS252010CX-100M-1 has 660 mA. For applications operating near saturation limits, the original or VLS252012ET-100M may be preferred. For standard operating conditions below 590 mA, all parts are functionally equivalent.
