VLS252015ET-100M Equivalent & Substitute Parts

Part Overview

The VLS252015ET-100M is a 10 µH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 660 mA continuous current with a maximum DC resistance of 588 mOhm. This surface mount component is packaged in the 1008 (2520 Metric) form factor and operates across the temperature range of -40°C to 105°C. The part carries a "Not For New Designs" status, indicating it has been superseded in TDK's product portfolio. Identifying equivalent substitute parts is necessary for ongoing production support, legacy system maintenance, and design continuity where this inductor specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS252015ET-100M is determined by the following critical parameters:

• Inductance Value: Must be 10 µH to maintain circuit functionality
• Current Rating: Must support minimum 660 mA continuous operation
• DC Resistance: Must not exceed 588 mOhm to preserve power dissipation characteristics
• Core Type and Shielding: Must be ferrite-based shielded drum core to maintain electromagnetic performance
• Package Footprint: Must be compatible with 1008 (2520 Metric) or equivalent physical dimensions (2.50mm L × 2.00mm W × 1.00mm H max)
• Mounting Type: Must be surface mount
• Temperature Range: Must support -40°C to 105°C operation
• Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The VLS252010CX-100M-1 meets these substitution criteria with equivalent inductance, compatible current handling, and matching physical form factor.

Parameter Comparison

Engineering Selection Recommendations

The VLS252010CX-100M-1 is the qualified substitute for the VLS252015ET-100M based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical inductance values (10 µH) and tolerance (±20%). The substitute provides a higher current rating (710 mA versus 660 mA), exceeding the original specification. DC resistance of the substitute (580 mOhm Max) is lower than the main part (588 mOhm Max), resulting in improved efficiency characteristics.

Physical Compatibility: Identical footprint dimensions and height ensure direct PCB layout compatibility without redesign requirements.

Compliance and Regulatory Status: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring equivalent environmental and regulatory standing.

Product Status Advantage: The substitute carries Active product status, providing long-term availability and supply chain stability compared to the main part's "Not For New Designs" designation.

Frequently Asked Questions (FAQ)

Q: Can the VLS252010CX-100M-1 be used as a direct replacement for the VLS252015ET-100M?

A: Yes. Both parts share identical inductance (10 µH), tolerance (±20%), physical dimensions (2.50mm × 2.00mm × 1.00mm), and operating temperature range (-40°C to 105°C). The substitute meets or exceeds all electrical specifications of the original part.

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

A: The primary differences are product status and electrical performance margins. The substitute (VLS252010CX-100M-1) is Active status with higher current rating (710 mA vs. 660 mA) and lower DC resistance (580 mOhm vs. 588 mOhm). The main part is designated "Not For New Designs."

Q: Are there any package or footprint considerations?

A: Both parts use the 1008 (2520 Metric) package with identical physical dimensions. The substitute is listed as "Nonstandard" package designation but maintains the same 2520 supplier device package specification, ensuring PCB compatibility without layout modifications.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting identical regulatory and environmental standards.

Q: Which part should be selected for new production?

A: The VLS252010CX-100M-1 is the appropriate choice for new production due to its Active product status, superior current rating margin, and lower DC resistance, while maintaining full compatibility with existing designs.
