VLS201612ET-4R7M Equivalent & Substitute Parts

Part Overview

The VLS201612ET-4R7M is a 4.7 µH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 700 mA with a maximum DC resistance of 438 mOhm. This component is classified as Not For New Designs, indicating it has been superseded in TDK's product portfolio. The part is surface mount, housed in a nonstandard 2.00mm x 1.60mm package, and is ROHS3 compliant with unlimited moisture sensitivity rating.

Due to its discontinued status for new designs, equivalent substitute parts from both TDK and alternative manufacturers are necessary for ongoing production support and design continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the VLS201612ET-4R7M is determined by the following critical parameters:

Inductance Value: Must be 4.7 µH (exact match required)
Inductance Tolerance: ±20% or tighter acceptable
Current Rating: Minimum 700 mA required; higher ratings acceptable
DC Resistance: Maximum 438 mOhm preferred; lower values acceptable
Shielding: Shielded configuration required
Core Material: Ferrite core required
Operating Temperature: Minimum -40°C ~ 105°C range required
Mounting Type: Surface mount required
Package Footprint: 2.00mm x 1.60mm (0806/2016 metric equivalent)

Engineering Selection Recommendations

VLS201610CX-4R7M-1 (TDK Corporation - Recommended Primary Substitute)

This part is the manufacturer-recommended substitute from TDK. It maintains the same inductance value, tolerance, and operating temperature range as the original VLS201612ET-4R7M. The higher current rating (1 A vs. 700 mA) and lower DC resistance (365 mOhm vs. 438 mOhm) provide improved performance margins. Active product status ensures long-term availability. The reduced height (1.00mm vs. 1.20mm) may require PCB layout verification for clearance-sensitive applications.

BWVC002016124R7M00 (Pulse Electronics - Alternative Substitute)

This Pulse Electronics inductor offers the lowest DC resistance (330 mOhm) among all options, delivering superior efficiency. Current rating of 810 mA exceeds the original specification. Extended operating temperature range (-55°C ~ 125°C) provides broader environmental compatibility. Active product status and ROHS3 compliance ensure supply continuity. Inductance tolerance remains ±20%, matching the original part.

BWVC002016124R7T00 (Pulse Electronics - Alternative Substitute)

This variant is electrically identical to BWVC002016124R7M00 with the exception of inductance tolerance (±30% vs. ±20%). Applications requiring tighter inductance tolerance should avoid this option. All other electrical and mechanical specifications remain equivalent to BWVC002016124R7M00.

Frequently Asked Questions (FAQ)

Q: Can VLS201610CX-4R7M-1 be used as a direct replacement for VLS201612ET-4R7M?

A: Yes. Both parts share identical inductance (4.7 µH), tolerance (±20%), operating temperature range (-40°C ~ 105°C), and package footprint (2.00mm x 1.60mm). The substitute has superior electrical characteristics with higher current rating and lower DC resistance. PCB layout verification is required due to reduced height (1.00mm vs. 1.20mm).

Q: What is the difference between BWVC002016124R7M00 and BWVC002016124R7T00?

A: The primary difference is inductance tolerance. BWVC002016124R7M00 maintains ±20% tolerance matching the original part, while BWVC002016124R7T00 has ±30% tolerance. All other electrical and mechanical parameters are identical. Select BWVC002016124R7M00 for applications requiring tighter inductance tolerance control.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts (VLS201610CX-4R7M-1, BWVC002016124R7M00, and BWVC002016124R7T00) are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the original VLS201612ET-4R7M compliance status.

Q: Which substitute offers the best thermal performance?

A: BWVC002016124R7M00 and BWVC002016124R7T00 provide the widest operating temperature range (-55°C ~ 125°C) compared to the original part and VLS201610CX-4R7M-1 (-40°C ~ 105°C). This extended range is beneficial for applications in extreme temperature environments.

Q: Can I use a substitute with higher current rating than the original specification?

A: Yes. All substitute parts have current ratings equal to or higher than the original 700 mA specification. Higher current ratings provide additional design margin and do not create compatibility issues in circuits designed for the original part's current rating.

Q: What packaging formats are available for these substitutes?

A: VLS201610CX-4R7M-1 is supplied in Cut Tape (CT) and Digi-Reel format. BWVC002016124R7M00 and BWVC002016124R7T00 are supplied in Tape & Reel (TR) format. The original VLS201612ET-4R7M is supplied in Tape & Reel format.
