• Tolerance: ±0.5%
• Power rating: 0.125W (1/8W)
• Package type: 0805 (2012 Metric)
• Composition: Metal Element
• Temperature coefficient: ±75ppm/°C
• Operating temperature range: -65°C to 170°C
• Automotive qualification: AEC-Q200
• Features: Current Sense, Moisture Resistant, Pulse Withstanding
• Moisture sensitivity: MSL 1

The substitute part WSL0805R0200DEK meets all electrical and mechanical parameters required for direct substitution. Both parts are manufactured by Vishay Dale within the WSL series and share identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

Both WSL0805R0200DBA and WSL0805R0200DEK are electrically and mechanically equivalent for current sense applications in automotive environments. Selection between these parts should be based on regulatory compliance requirements and supply availability.

The WSL0805R0200DEK offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with strict environmental regulations. The WSL0805R0200DBA is RoHS non-compliant and REACH affected, requiring verification against specific application requirements.

Inventory availability differs significantly, with WSL0805R0200DEK offering substantially higher stock levels (2985 units versus 719 units). Both parts maintain identical electrical performance, temperature stability, and automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can WSL0805R0200DEK replace WSL0805R0200DBA in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters including resistance, tolerance, power rating, temperature coefficient, and package dimensions. Substitution is valid from a technical standpoint. Regulatory compliance differences (RoHS and REACH status) must be evaluated against application requirements.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use the 0805 (2012 Metric) package with identical dimensions: 0.080" L x 0.050" W (2.03mm x 1.27mm) and maximum seated height of 0.018" (0.46mm). PCB footprints are interchangeable.

Q: What is the significance of the different RoHS and REACH statuses?

A: RoHS and REACH compliance are regulatory designations that vary by manufacturing batch or supplier classification. WSL0805R0200DEK carries ROHS3 compliance and REACH unaffected status, while WSL0805R0200DBA is marked as RoHS non-compliant and REACH affected. Selection depends on end-product regulatory requirements and target markets.

Q: Are both parts suitable for automotive current sense applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and are specifically designed for current sense applications with moisture resistance and pulse withstanding capability. Operating temperature range of -65°C to 170°C supports automotive environmental requirements.

Q: What is MSL 1 rating and why is it important?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life with no moisture precautions required. Both parts carry this rating, eliminating moisture-related handling constraints during storage and assembly.
