Substitute Part Grouping Explanation

Substitution for the WSR2R0800FEB is determined by strict equivalence across the following critical parameters:

• Resistance value: 80 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package type: 4527 J-Lead
• Composition: Metal Element
• Temperature coefficient: ±75ppm/°C
• Operating temperature range: -65°C ~ 275°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

The substitute part WSR2R0800FEA meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

Both WSR2R0800FEB and WSR2R0800FEA are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and supply chain considerations. The WSR2R0800FEA currently has higher inventory (5400 units) compared to WSR2R0800FEB (1136 units). Both parts carry ROHS3 compliance and AEC-Q200 automotive qualification, making them suitable for regulated automotive applications. The identical parameter set ensures direct substitution without circuit redesign or validation modifications.

Frequently Asked Questions (FAQ)
