Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS252008ET-100M is determined by the following critical parameters:

Inductance value must remain 10 µH with ±20% tolerance to maintain circuit functionality. Core material must be ferrite with shielding to preserve electromagnetic isolation characteristics. Operating temperature range must span -40°C to 105°C minimum to ensure thermal compatibility. Mounting type must be surface mount to support PCB assembly compatibility. Package footprint dimensions (2.50mm x 2.00mm) must be maintained for mechanical fit.

The substitute part VLS252010CX-100M-1 meets all these core requirements while offering improved electrical performance through reduced DC resistance and higher current rating capacity.

Parameter Comparison

Engineering Selection Recommendations

The VLS252010CX-100M-1 is the qualified substitute for VLS252008ET-100M based on the following engineering criteria:

Both components maintain identical inductance values and tolerance specifications, ensuring circuit performance equivalence. Both are ROHS3 compliant and REACH unaffected, meeting regulatory requirements. The substitute part carries Active product status, providing long-term supply chain assurance compared to the Not For New Designs status of the original part.

The VLS252010CX-100M-1 demonstrates superior electrical characteristics with 73% reduction in DC resistance (580 mOhm versus 1.232 Ohm) and 73% increase in current rating capacity (710 mA versus 410 mA). These improvements reduce power dissipation and thermal stress in the application circuit.

Height difference of 0.008" (0.20mm) between seated positions must be evaluated for PCB clearance compatibility in space-constrained layouts.

Frequently Asked Questions (FAQ)

Q: Can VLS252010CX-100M-1 be used as a direct replacement for VLS252008ET-100M?

A: Yes, for applications where the original current rating of 410 mA is sufficient. The substitute maintains identical inductance, tolerance, core material, shielding, operating temperature range, and footprint dimensions. PCB height clearance must be verified due to the 0.20mm increase in seated height.

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

A: The primary differences are DC resistance (1.232 Ohm versus 580 mOhm), current rating (410 mA versus 710 mA), saturation current (430 mA versus 660 mA), and product status (Not For New Designs versus Active). These differences result in lower power dissipation and higher current capacity for the substitute part.

Q: Are both parts compatible with the same PCB assembly process?

A: Both components use surface mount technology with identical footprint dimensions (2.50mm x 2.00mm). The 0.20mm height difference may require reflow profile adjustment or clearance verification depending on PCB design constraints.

Q: What compliance certifications apply to both parts?

A: Both VLS252008ET-100M and VLS252010CX-100M-1 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8504.50.4000. Moisture sensitivity level is 1 (Unlimited) for both components.

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

A: This designation indicates the VLS252008ET-100M has been superseded in TDK's active product line. The VLS252010CX-100M-1 represents the current generation equivalent with improved performance characteristics and guaranteed long-term availability.
