Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS3015ET-2R2M is determined by the following critical parameters:

• Inductance Value: Must be 2.2 µH with tolerance ±20% or tighter
• Current Rating: Must meet or exceed 1.35 A minimum
• DC Resistance: Must not exceed 84mOhm to maintain circuit performance
• Shielding: Must be shielded or semi-shielded to control electromagnetic interference
• Core Material: Ferrite core required for frequency stability
• Operating Temperature: Must support -40°C minimum and 105°C maximum
• Mounting Type: Surface mount only
• Physical Footprint: 3.00mm x 3.00mm base dimension with height ≤ 1.50mm preferred
• Compliance: ROHS3 compliant, MSL 1 rating

All substitute parts listed meet these core electrical and mechanical requirements. Differences in current saturation ratings, product status, and packaging format are noted for design consideration.

Parameter Comparison

Engineering Selection Recommendations

VLS3012CX-2R2M-1 (TDK Corporation, Active Status) This direct TDK alternative maintains the same inductance, tolerance, and operating temperature range as the main part. It offers improved current rating (2.83 A) and lower DC resistance (74mOhm), providing enhanced performance margin. The reduced height (1.20mm) may offer PCB layout advantages. Active product status ensures long-term availability.

BWVF003030152R2M00 (Pulse Electronics, Active Status) This Pulse Electronics substitute meets all core electrical requirements with 2 A current rating and 90mOhm DCR. Extended operating temperature range (-55°C to 125°C) provides broader environmental coverage. Active product status supports production continuity.

BWVF003030152R2T00 (Pulse Electronics, Active Status) This variant maintains shielded construction with 1.8 A current rating and 90mOhm DCR. Inductance tolerance of ±30% is wider than the main part. Extended temperature range and active status support long-term supply. Package designation as 1212 (3030 Metric) confirms mechanical compatibility.

SRN3015-2R2M (Bourns Inc., Active Status) The Bourns semi-shielded alternative provides the lowest DC resistance (72mOhm) among substitutes, supporting efficient circuit operation. Current rating of 1.8 A exceeds the main part requirement. Extended upper temperature limit (125°C) and active product status ensure availability. Semi-shielded construction differs from fully shielded main part; electromagnetic interference characteristics should be evaluated for specific applications.

Frequently Asked Questions (FAQ)

Q: Can I use VLS3012CX-2R2M-1 as a direct replacement for VLS3015ET-2R2M? A: Yes. Both parts are TDK 2.2 µH inductors with identical inductance tolerance (±20%), same operating temperature range, and matching 3.00mm x 3.00mm footprint. The VLS3012CX-2R2M-1 offers superior current rating (2.83 A vs. 1.35 A) and lower DCR (74mOhm vs. 84mOhm), making it a performance-enhanced substitute. The reduced height (1.20mm vs. 1.50mm) may require PCB layout verification.

Q: What is the difference between shielded and semi-shielded inductors? A: Shielded inductors (VLS3015ET-2R2M, VLS3012CX-2R2M-1, BWVF series) provide complete electromagnetic containment, minimizing radiated interference. Semi-shielded inductors (SRN3015-2R2M) offer partial shielding with lower cost and reduced height. Semi-shielded construction may introduce higher electromagnetic coupling to adjacent components; circuit layout and noise sensitivity must be evaluated.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the main part's environmental and regulatory status.

Q: What is the significance of MSL 1 rating? A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake-out requirements. All listed parts carry this rating, eliminating moisture management concerns during storage and handling.

Q: Can I use BWVF003030152R2T00 if my circuit requires ±20% inductance tolerance? A: No. BWVF003030152R2T00 specifies ±30% tolerance, which exceeds the ±20% tolerance of the main part. Use this substitute only if your circuit design accommodates the wider tolerance band.

Q: Which substitute offers the best thermal performance? A: BWVF003030152R2M00 and BWVF003030152R2T00 (Pulse Electronics) support -55°C to 125°C, extending the lower temperature limit by 15°C and upper limit by 20°C compared to the main part. SRN3015-2R2M (Bourns) extends the upper limit to 125°C. TDK VLS3012CX-2R2M-1 maintains the original -40°C to 105°C range.

Q: What packaging options are available? A: VLS3015ET-2R2M, VLS3012CX-2R2M-1, and BWVF series are supplied in Tape & Reel (TR) format. SRN3015-2R2M is available in Cut Tape (CT) and Digi-Reel® packaging. Verify packaging compatibility with your assembly process requirements.

Q: Why is the main part marked "Not For New Designs"? A: This status indicates TDK has discontinued active development and recommends alternative parts for new applications. VLS3012CX-2R2M-1 is the recommended TDK successor. All substitute parts carry Active status, ensuring long-term production support.
