Substitute Part Grouping Explanation

Substitution eligibility for the WSL20105L000FTB is determined by strict equivalence across the following critical parameters:

• Resistance value: 5 mOhms
• Tolerance: ±1%
• Power rating: 0.5W / 1/2W
• Package / Case: 2010 (5025 Metric)
• Composition: Metal Element
• Temperature coefficient: ±110ppm/°C
• Operating temperature range: -65°C ~ 170°C
• Automotive qualification: AEC-Q200
• Features: Current Sense, Moisture Resistant, Pulse Withstanding
• Moisture Sensitivity Level: MSL 1
• Termination count: 2
• Physical dimensions: 0.200" L x 0.100" W (5.08mm x 2.54mm)
• Maximum seated height: 0.035" (0.89mm)

The WSL20105L000FEB meets all these criteria and is classified as a direct equivalent substitute. The primary distinction between the main part and substitute is the packaging format (Tape & Reel for both) and compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both WSL20105L000FTB and WSL20105L000FEB are electrically and mechanically identical current sense resistors qualified to AEC-Q200 automotive standards. Selection between these parts should be based on compliance and regulatory requirements:

The WSL20105L000FEB is ROHS3 compliant and REACH unaffected, making it suitable for applications with strict environmental and regulatory compliance mandates. The WSL20105L000FTB is RoHS non-compliant and REACH affected, which may be acceptable for legacy systems or applications without compliance constraints.

Both parts maintain identical electrical performance, thermal characteristics, and mechanical fit within the 2010 (5025 Metric) package footprint. The WSL20105L000FEB offers higher inventory availability at 5820 pieces compared to 1149 pieces for the main part.
