Key Parameters

Substitute Part Grouping Explanation

Substitution for the WSL2010R2000FTA18 is determined by the following critical parameters:

• Resistance value: 200 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2010 (5025 Metric)
• Composition: Metal Element
• Temperature coefficient: ±75ppm/°C
• Operating temperature range: -65°C ~ 170°C
• Automotive qualification: AEC-Q200
• Functional features: Current sense, moisture resistant, pulse withstanding

The WSL2010R2000FEA18 qualifies as a direct substitute, matching all electrical and mechanical parameters while differing only in RoHS compliance status and REACH classification.

Parameter Comparison

Engineering Selection Recommendations

The WSL2010R2000FEA18 is a direct functional equivalent to the WSL2010R2000FTA18. Both parts are manufactured by Vishay Dale within the WSL-HP series and maintain identical electrical specifications, mechanical dimensions, and automotive AEC-Q200 qualification.

The primary distinction is regulatory compliance: the WSL2010R2000FEA18 is ROHS3 compliant, while the WSL2010R2000FTA18 is RoHS non-compliant. Additionally, the substitute part is REACH unaffected compared to the main part's REACH affected status.

Selection between these parts should be based on project-specific compliance requirements. Applications requiring RoHS3 compliance should specify the WSL2010R2000FEA18. Applications with no RoHS requirement may use either part interchangeably from an electrical and mechanical standpoint.

Frequently Asked Questions (FAQ)

Q: Can WSL2010R2000FEA18 be used as a direct replacement for WSL2010R2000FTA18?
