VLS252012ET-R47N Equivalent & Substitute Parts

Part Overview

The VLS252012ET-R47N is a 470 nH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 2.15 A continuous current with a maximum DC resistance of 56 mOhm. This component is designed for surface mount applications in the 1008 (2520 Metric) package format. The part carries a "Not For New Designs" status, making identification of functionally equivalent alternatives essential for ongoing production and design updates. Substitute parts must maintain the same inductance value, core shielding characteristics, and compatible package dimensions while meeting or exceeding electrical performance requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the VLS252012ET-R47N is determined by the following critical parameters:

• Inductance Value: Must be 470 nH to maintain circuit functionality
• Core Material & Shielding: Must be ferrite with shielding to preserve electromagnetic isolation
• Package Dimensions: Must be compatible with 1008 (2520 Metric) footprint (2.50mm L × 2.00mm W × 1.00mm H max)
• Current Rating: Substitute must support minimum 2.15 A continuous current
• DC Resistance: Lower or equal DCR values are acceptable; higher values may impact circuit performance
• Operating Temperature: Must support -40°C ~ 105°C range
• Surface Mount Compatibility: Must be suitable for SMD assembly processes

The VLS252010CX-R47M-1 meets these substitution criteria with improved electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The VLS252010CX-R47M-1 is the qualified substitute for the VLS252012ET-R47N based on the following engineering criteria:

Electrical Performance: The substitute provides superior electrical characteristics with a higher current rating (3.22 A vs. 2.15 A), lower DC resistance (38 mOhm vs. 56 mOhm), and tighter inductance tolerance (±20% vs. ±30%). These improvements ensure enhanced thermal performance and reduced power dissipation in the circuit.

Compliance & Certifications: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity ratings (MSL 1). Operating temperature ranges are identical across both components.

Product Status: The substitute carries an Active product status, ensuring long-term availability and continued manufacturer support, whereas the main part is designated "Not For New Designs."

Physical Compatibility: Both components share identical footprint dimensions (2.50mm × 2.00mm) and maximum seated height (1.00mm), enabling direct PCB layout compatibility. The supplier device package designation (2520) confirms mechanical interchangeability despite the nonstandard package classification of the substitute.

Frequently Asked Questions (FAQ)

Q: Can the VLS252010CX-R47M-1 be used as a direct replacement for the VLS252012ET-R47N?

A: Yes. Both components share identical inductance values (470 nH), core shielding characteristics, and physical dimensions (2.50mm × 2.00mm × 1.00mm). The substitute meets or exceeds all electrical requirements of the main part.

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

A: The substitute offers improved performance with higher current rating (3.22 A vs. 2.15 A), lower DC resistance (38 mOhm vs. 56 mOhm), and tighter inductance tolerance (±20% vs. ±30%). The main part is obsolete (Not For New Designs), while the substitute is Active.

Q: Are there any package compatibility concerns?

A: No. Despite the substitute being classified as "Nonstandard" package, the supplier device package designation (2520) and physical dimensions confirm compatibility with the 1008 (2520 Metric) footprint. PCB layouts require no modification.

Q: Does the lower DC resistance of the substitute affect circuit operation?

A: No. Lower DC resistance is a beneficial characteristic that reduces power dissipation and improves thermal performance. This does not negatively impact circuit functionality.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the VLS252012ET-R47N and VLS252010CX-R47M-1 are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.

Q: What is the inductance tolerance difference, and does it matter?

A: The main part has ±30% tolerance while the substitute has ±20% tolerance. The tighter tolerance of the substitute provides better circuit predictability and reduced performance variation across production batches.
