Both parts are manufactured by Vishay Dale within the WSL series and maintain identical electrical and mechanical specifications required for current sensing applications.

Parameter Comparison

Engineering Selection Recommendations

The WSL2010R0100FEB is a direct functional equivalent to the WSL2010R0100FTB for all current sensing applications requiring identical electrical and mechanical specifications. Both parts maintain active production status and AEC-Q200 automotive qualification.

Selection between these parts should be based on compliance requirements and inventory availability:

• WSL2010R0100FTB: Select when RoHS non-compliant designs are acceptable and REACH-affected material status is permissible.
• WSL2010R0100FEB: Select for applications requiring ROHS3 compliance and REACH-unaffected material status. This part offers significantly higher inventory availability (15,446 pieces versus 680 pieces).

Both parts are suitable for automotive and industrial current sensing circuits operating within the specified temperature range and power constraints.

Frequently Asked Questions (FAQ)

Q: Can WSL2010R0100FEB replace WSL2010R0100FTB in existing designs?

A: Yes. Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, package dimensions, and temperature specifications. The primary differences are RoHS and REACH compliance status.

Q: What is the difference between the RoHS and REACH compliance status?

A: WSL2010R0100FTB is RoHS non-compliant and REACH-affected. WSL2010R0100FEB is ROHS3 compliant and REACH-unaffected. Selection depends on your application's regulatory requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 2010 (5025 Metric) package with identical length (0.200" / 5.08mm), width (0.100" / 2.54mm), and maximum seated height (0.035" / 0.89mm).

Q: Do both parts have the same temperature operating range?

A: Yes. Both parts operate from -65°C to 170°C with identical temperature coefficient of ±75 ppm/°C.

Q: Which part should I select for new designs?

A: Selection should be based on your application's compliance requirements. For designs requiring ROHS3 and REACH compliance, use WSL2010R0100FEB. For designs without these requirements, either part is suitable based on availability.

Q: Are both parts automotive qualified?

A: Yes. Both parts carry AEC-Q200 automotive qualification and are suitable for automotive current sensing applications.
