VLS252012ET-6R8M Equivalent & Substitute Parts

Part Overview

The VLS252012ET-6R8M is a 6.8 µH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 650 mA continuous current with a maximum DC resistance of 612 mOhm. This surface mount component is housed in a 1008 (2520 Metric) package and operates across the temperature range of -40°C to 105°C. The part is classified as "Not For New Designs," indicating it has been superseded in TDK's product portfolio. Identifying equivalent and substitute parts is necessary for applications requiring continued supply, design flexibility, or performance optimization within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLS252012ET-6R8M is determined by the following critical parameters:

• Inductance Value: Must be 6.8 µH
• Inductance Tolerance: ±20% or tighter
• Current Rating: Minimum 650 mA continuous current capability
• Saturation Current (Isat): Minimum 850 mA
• DC Resistance (DCR): Lower or equal to 612 mOhm preferred for thermal performance
• Core Material: Ferrite shielded construction
• Package / Case: 1008 (2520 Metric) or mechanically compatible equivalent
• Mounting Type: Surface Mount
• Operating Temperature Range: Must encompass or exceed -40°C ~ 105°C
• Compliance: ROHS3 Compliant, MSL 1

Three substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

VLS252010CX-6R8M-1 (TDK Corporation)

This part is the manufacturer-recommended substitute from TDK. It maintains identical inductance, tolerance, and operating temperature range. The current rating increases to 860 mA with reduced DC resistance of 372 mOhm, providing improved thermal performance. The part is classified as Active and ROHS3 compliant. The package designation is listed as Nonstandard but maintains the 2520 metric footprint with identical physical dimensions and height to the main part. This substitute is suitable for direct replacement in existing designs.

BWVF002520126R8M00 (Pulse Electronics)

This part meets all electrical substitution criteria with 720 mA current rating and 300 mOhm DC resistance, both superior to the main part. The package is standard 1008 (2520 Metric) with identical footprint dimensions. Height is increased to 0.049" (1.25mm) compared to 0.039" (1.00mm) on the main part. Operating temperature range extends to -55°C ~ 125°C. The part is Active and ROHS3 compliant. Physical height difference must be evaluated for PCB layout compatibility.

BWVF002520126R8T00 (Pulse Electronics)

This part is electrically equivalent to BWVF002520126R8M00 with identical current rating, saturation current, and DC resistance. Inductance tolerance is ±30%, which is wider than the main part's ±20%. All other specifications including package, dimensions, temperature range, and compliance certifications are identical to BWVF002520126R8M00. The wider tolerance may impact circuit performance in applications requiring tighter inductance control.

Frequently Asked Questions (FAQ)

Q: Can VLS252010CX-6R8M-1 be used as a direct replacement for VLS252012ET-6R8M?

A: Yes. Both parts share identical inductance (6.8 µH), tolerance (±20%), operating temperature range (-40°C ~ 105°C), and physical footprint (2.50mm x 2.00mm). The substitute offers improved current rating (860 mA vs 650 mA) and lower DC resistance (372 mOhm vs 612 mOhm). The package designation difference (Nonstandard vs 1008) does not affect mechanical compatibility.

Q: What is the primary difference between BWVF002520126R8M00 and BWVF002520126R8T00?

A: The primary difference is inductance tolerance. BWVF002520126R8M00 has ±20% tolerance matching the main part, while BWVF002520126R8T00 has ±30% tolerance. All other electrical and mechanical parameters are identical. Applications requiring tighter inductance control should use BWVF002520126R8M00.

Q: Will the increased height of Pulse Electronics parts affect PCB assembly?

A: Pulse Electronics substitutes (BWVF series) have a maximum seated height of 0.049" (1.25mm) compared to 0.039" (1.00mm) for the main part and TDK substitute. This 0.010" (0.25mm) difference must be evaluated against PCB layout constraints, component clearances, and assembly equipment specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the main part VLS252012ET-6R8M.

Q: Which substitute offers the best thermal performance?

A: BWVF002520126R8M00 and BWVF002520126R8T00 both offer the lowest DC resistance at 300 mOhm, compared to 612 mOhm for the main part and 372 mOhm for VLS252010CX-6R8M-1. Lower DC resistance reduces resistive heating in the inductor.

Q: Can these parts be used in applications requiring the full -40°C ~ 105°C temperature range?

A: Yes. All substitute parts support or exceed the main part's operating temperature range. Pulse Electronics parts extend the range to -55°C ~ 125°C, providing additional margin for extreme environment applications.
