VLS201610ET-4R7M Equivalent & Substitute Parts

Part Overview

The VLS201610ET-4R7M is a 4.7 µH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 640 mA continuous current with a maximum DC resistance of 554 mOhm. This surface mount component operates across the temperature range of -40°C to 105°C and is classified as not for new designs. Due to its discontinued status and limited availability relative to active alternatives, equivalent substitute parts from both TDK and Pulse Electronics are available to maintain design continuity and ensure supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS201610ET-4R7M is determined by the following critical parameters:

• Inductance Value: Must be 4.7 µH
• Inductance Tolerance: ±20% or ±30% acceptable
• Current Rating: Minimum 640 mA continuous current capability
• DC Resistance (DCR): Maximum 554 mOhm preferred; higher values acceptable if current rating is maintained
• Shielding: Must be shielded
• Operating Temperature Range: Must support -40°C minimum; 105°C or higher acceptable
• Mounting Type: Surface mount required
• Package Footprint: 2.00mm x 1.60mm (0806/2016 metric equivalent)
• Compliance: ROHS3 compliant, MSL 1

All substitute parts listed meet or exceed these criteria, ensuring functional and mechanical compatibility within the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: VLS201610CX-4R7M-1

The VLS201610CX-4R7M-1 from TDK Corporation is the manufacturer-recommended direct substitute. It maintains identical inductance, tolerance, and operating temperature range as the original part while providing superior electrical performance with 1 A current rating and reduced DCR of 365 mOhm. Active product status ensures long-term availability and supply chain stability. This part is suitable for new designs and represents the optimal replacement path.

Secondary Recommendations: Pulse Electronics BWVC Series

The BWVC002016104R7M00 and BWVC002016104R7T00 from Pulse Electronics provide equivalent functionality with extended operating temperature range (-55°C to 125°C). Both parts exceed the 640 mA current requirement with 810 mA rating and feature lower DCR at 360 mOhm. The BWVC002016104R7M00 maintains ±20% tolerance matching the original specification. Active status and ROHS3 compliance confirm suitability for production use.

Alternative Option: Pulse Electronics BWVH Series

The BWVH002016104R7MH1 and BWVH002016104R7TH1 provide substitution capability with 680 mA current rating, meeting the 640 mA requirement. These parts feature extended temperature range and ROHS3 compliance. The ±20% tolerance variant (BWVH002016104R7MH1) aligns with original specifications. Selection of this series is appropriate when BWVC variants are unavailable.

All substitute parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can VLS201610CX-4R7M-1 be used as a direct replacement for VLS201610ET-4R7M?

A: Yes. Both parts share identical inductance (4.7 µH), tolerance (±20%), and operating temperature range (-40°C to 105°C). The VLS201610CX-4R7M-1 provides superior current handling (1 A vs. 640 mA) and lower DC resistance (365 mOhm vs. 554 mOhm), making it functionally superior. Height increases from 0.95 mm to 1.00 mm; verify PCB clearance in your design.

Q: What is the difference between BWVC002016104R7M00 and BWVC002016104R7T00?

A: Both parts are electrically identical with 4.7 µH inductance, 810 mA current rating, and 360 mOhm DCR. The primary difference is inductance tolerance: BWVC002016104R7M00 specifies ±20%, while BWVC002016104R7T00 specifies ±30%. Select BWVC002016104R7M00 when tighter tolerance control is required.

Q: Are Pulse Electronics BWVH parts suitable replacements?

A: Yes, with current rating consideration. BWVH002016104R7MH1 and BWVH002016104R7TH1 both provide 680 mA continuous current, exceeding the 640 mA requirement. DC resistance is higher at 520 mOhm compared to the original 554 mOhm maximum, remaining within acceptable margins. Extended temperature range (-55°C to 125°C) provides additional operational flexibility.

Q: Do all substitute parts maintain the same package footprint?

A: Yes. All substitute parts use the 0806 (2016 metric) package with 2.00 mm length and 1.60 mm width, matching the original footprint. Height varies slightly: original is 0.95 mm, TDK substitute is 1.00 mm, and Pulse Electronics BWVH variants are 1.02 mm. Verify PCB assembly clearance for components in close proximity.

Q: Which substitute part has the lowest DC resistance?

A: VLS201610CX-4R7M-1 and BWVC series parts both feature 360 mOhm DCR, significantly lower than the original 554 mOhm specification. This reduction improves thermal performance and power efficiency in the application circuit.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification with MSL 1 rating, meeting standard environmental and manufacturing requirements for production assembly.
