Engineering Selection Recommendations

VLS3012CX-2R2M-1 (TDK Corporation): This is the direct TDK equivalent with Active product status. It maintains identical inductance, tolerance, package footprint, and operating temperature range. The improved current rating (2.83 A vs. 1.35 A) and lower DC resistance (74mOhm vs. 96mOhm) provide enhanced performance margin. This part is the preferred choice for designs requiring continuity within the TDK VLS product family.

BWVF003030122R2M00 (Pulse Electronics): An Active alternative from Pulse Electronics with matching inductance and package footprint. Current rating of 2 A exceeds the original specification. DC resistance of 92mOhm is comparable. Extended operating temperature range (-55°C ~ 125°C) provides additional thermal margin. ROHS3 compliance and MSL 1 rating ensure regulatory and environmental compatibility.

BWVF003030122R2T00 (Pulse Electronics): An Active Pulse Electronics option with identical inductance and footprint. Current rating of 1.8 A meets application requirements. Inductance tolerance of ±30% is wider than the original ±20%. Extended temperature range (-55°C ~ 125°C) and improved DC resistance (92mOhm) support robust circuit operation. Suitable for applications where tolerance relaxation is acceptable.

CDRH2D14NP-2R2NC (Sumida America Components Inc.): An Active shielded inductor with matching inductance and ferrite core. Current rating of 1.6 A exceeds the original 1.35 A specification. DC resistance of 94mOhm is within acceptable range. Height of 1.55mm exceeds the original 1.20mm maximum, requiring PCB layout verification. Operating temperature range of -40°C ~ 100°C is slightly narrower at the upper limit.

SRU2016-2R2Y (Bourns Inc.): An Active drum core, wirewound inductor matching the original construction type. Inductance and shielding specifications align with the main part. Current rating of 1.6 A and saturation current of 1 A require circuit validation. DC resistance of 105mOhm is slightly elevated. Package footprint of 2.80mm x 2.80mm is smaller in XY dimensions but taller at 1.80mm, necessitating PCB design review. Extended operating temperature range (-40°C ~ 125°C) and documented Q factor (8 @ 7.96MHz) provide additional performance data.

Frequently Asked Questions (FAQ)

Q: Can I directly replace VLS3012ET-2R2M with VLS3012CX-2R2M-1?

A: Yes. Both parts are TDK Corporation inductors with identical inductance (2.2 µH), tolerance (±20%), package footprint (3.00mm x 3.00mm), and operating temperature range (-40°C ~ 105°C). VLS3012CX-2R2M-1 has Active product status and improved electrical performance (higher current rating and lower DC resistance). No circuit modifications are required.

Q: What is the key difference between the main part and substitute options?

A: The VLS3012ET-2R2M is classified as "Not For New Designs." All substitute parts listed have Active product status, ensuring long-term availability and supply chain stability. Electrical parameters (inductance, shielding, core material) remain consistent across all options. Variations exist in current rating, DC resistance, and operating temperature range to accommodate different application requirements.

Q: Are there package footprint differences I should consider?

A: Most substitutes maintain the 3.00mm x 3.00mm footprint. CDRH2D14NP-2R2NC has a maximum height of 1.55mm (vs. 1.20mm original), and SRU2016-2R2Y has a smaller XY footprint (2.80mm x 2.80mm) but greater height (1.80mm). PCB layout verification is required if selecting these alternatives.

Q: Do all substitute parts meet RoHS and MSL requirements?

A: Yes. All substitute parts listed are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original VLS3012ET-2R2M specifications.

Q: Which substitute offers the best performance improvement?

A: VLS3012CX-2R2M-1 provides the most direct upgrade, with higher current rating (2.83 A) and lower DC resistance (74mOhm), while maintaining identical package and temperature specifications. BWVF003030122R2M00 and BWVF003030122R2T00 offer extended temperature ranges (-55°C ~ 125°C) for applications requiring broader thermal operation.

Q: What should I verify before selecting a substitute?

A: Confirm that the substitute's current rating meets or exceeds your circuit's maximum current requirement. Verify DC resistance compatibility with your impedance budget. For CDRH2D14NP-2R2NC and SRU2016-2R2Y, validate PCB layout clearance due to height variations. Confirm operating temperature range covers your application's thermal envelope.
