Substitute Part Grouping Explanation

Substitution eligibility for the WSL20109L300FTA is determined by strict equivalence across the following critical parameters:

• Resistance value: 9.3 mOhms
• Tolerance: ±1%
• Power rating: 0.5W / 1/2W
• Package / Case: 2010 (5025 Metric)
• Composition: Metal Element
• Temperature coefficient: ±75ppm/°C
• Operating temperature range: -65°C ~ 170°C
• Automotive qualification: AEC-Q200
• Features: Current Sense, Moisture Resistant, Pulse Withstanding
• Moisture Sensitivity Level: 1 (Unlimited)

The WSL20109L300FEA meets all these criteria and is classified as a direct substitute. Both parts are manufactured by Vishay Dale within the WSL series and share identical electrical specifications and mechanical dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both WSL20109L300FTA and WSL20109L300FEA are electrically and mechanically equivalent for current sensing applications in automotive circuits. Selection between these parts should be based on the following factors:

WSL20109L300FTA is suitable for applications where RoHS non-compliance and REACH Affected status are acceptable within the design and supply chain requirements.

WSL20109L300FEA is the preferred choice for designs requiring ROHS3 compliance and REACH Unaffected status. This part also offers higher inventory availability (4701 pieces versus 1058 pieces), providing improved supply chain flexibility.

Both parts maintain identical electrical performance, thermal characteristics, and automotive AEC-Q200 qualification. The choice between them depends solely on regulatory compliance requirements and supply chain considerations specific to the application and end market.

Frequently Asked Questions (FAQ)

Q: Can WSL20109L300FEA be used as a direct replacement for WSL20109L300FTA in automotive current sensing circuits?

A: Yes. Both parts are electrically and mechanically identical with matching resistance values, tolerances, power ratings, temperature coefficients, and operating ranges. They share the same 2010 (5025 Metric) package and AEC-Q200 automotive qualification.

Q: What is the difference between these two part numbers?

A: The primary differences are RoHS and REACH compliance status. WSL20109L300FEA is ROHS3 compliant and REACH Unaffected, while WSL20109L300FTA is RoHS non-compliant and REACH Affected. All electrical and mechanical specifications are identical.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate across -65°C to 170°C with identical temperature coefficients of ±75ppm/°C and the same 0.5W power rating. Performance in current sensing applications is equivalent.

Q: Do both parts come in the same packaging format?

A: Yes. Both WSL20109L300FTA and WSL20109L300FEA are supplied in Tape & Reel (TR) packaging with identical tape specifications and reel configurations.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For designs requiring ROHS3 compliance or REACH Unaffected status, WSL20109L300FEA is the appropriate choice. For applications without these constraints, either part is suitable based on availability and supply chain considerations.

Q: Is the MSL rating the same for both parts?

A: Yes. Both parts have MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture sensitivity concerns for storage and handling.
