Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WSL2010R5000FTB18 is determined by matching the following critical parameters:

• Resistance value: 500 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2010 (5025 Metric)
• Composition: Metal Element
• Temperature coefficient: ±75ppm/°C
• Operating temperature range: -65°C ~ 170°C
• Automotive qualification: AEC-Q200
• Moisture sensitivity level: 1 (Unlimited)

The identified substitute WSL2010R5000FEA18 matches all electrical and mechanical parameters. The primary distinction between the main part and substitute is the RoHS compliance status, which affects material composition and environmental regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Both WSL2010R5000FTB18 and WSL2010R5000FEA18 are functionally equivalent for electrical and mechanical performance in automotive current sense applications. Selection between these parts should be based on regulatory and compliance requirements:

The WSL2010R5000FEA18 is ROHS3 compliant and REACH unaffected, making it suitable for applications subject to European environmental regulations and RoHS directives. The WSL2010R5000FTB18 is RoHS non-compliant and may be appropriate for legacy designs or applications without RoHS requirements. Both parts maintain identical electrical characteristics, thermal performance, and automotive AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can WSL2010R5000FEA18 be used as a direct replacement for WSL2010R5000FTB18?

A: Yes. Both parts are identical in resistance value (500 mOhms), tolerance (±1%), power rating (1W), package type (2010), temperature coefficient (±75ppm/°C), operating temperature range (-65°C ~ 170°C), and AEC-Q200 automotive qualification. The primary difference is RoHS compliance status.

Q: What is the significance of the RoHS compliance difference?

A: RoHS compliance affects material composition and environmental regulatory acceptance. WSL2010R5000FEA18 is ROHS3 compliant, meeting European Union Restriction of Hazardous Substances directives. WSL2010R5000FTB18 is non-compliant. Selection depends on end-use market and regulatory requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical dimensions: 0.200" L x 0.100" W (5.08mm x 2.54mm) with maximum seated height of 0.035" (0.89mm). PCB layout and assembly processes require no modification.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Q: What is the packaging format for both parts?

A: Both parts are supplied in Tape & Reel (TR) format, standard for automated assembly processes.
