Substitute Part Grouping Explanation

Substitution eligibility for the WSL2010R0150FTB is determined by strict equivalence across the following critical parameters:

• Resistance value: 15 mOhms
• Tolerance: ±1%
• Power rating: 0.5W
• Package format: 2010 (5025 Metric)
• Composition: Metal Element
• Temperature coefficient: ±75 ppm/°C
• Operating temperature range: -65°C to 170°C
• Automotive qualification: AEC-Q200
• Application features: Current Sense, Moisture Resistant, Pulse Withstanding
• Termination count: 2
• Moisture sensitivity: MSL 1

The WSL2010R0150FEB qualifies as a direct substitute based on identical electrical specifications and package dimensions. The only difference is packaging format: the main part is supplied in Tape & Reel (TR), while the substitute is available in Cut Tape (CT) & Digi-Reel® format. Both parts maintain the same component footprint, electrical performance, and automotive compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the WSL2010R0150FTB and WSL2010R0150FEB are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

WSL2010R0150FTB (Tape & Reel): Use this part number when high-volume automated assembly is required. Tape & Reel packaging is optimized for pick-and-place equipment and provides efficient component feeding in production environments.

WSL2010R0150FEB (Cut Tape & Digi-Reel®): Use this part number when lower-volume production, prototyping, or manual assembly is required. Cut Tape and Digi-Reel® formats provide flexibility for smaller batch quantities and alternative handling methods.

Regulatory Compliance Consideration: The WSL2010R0150FEB carries ROHS3 compliance and REACH Unaffected status, while the WSL2010R0150FTB is RoHS non-compliant and REACH Affected. For applications subject to RoHS3 or REACH regulations, the WSL2010R0150FEB is the appropriate selection.

Both parts maintain AEC-Q200 automotive qualification and are suitable for current sensing applications across the full operating temperature range of -65°C to 170°C.

Frequently Asked Questions (FAQ)

Q: Can WSL2010R0150FEB be used as a direct replacement for WSL2010R0150FTB in PCB assembly?

A: Yes. Both parts have identical electrical specifications, resistance value, tolerance, power rating, package dimensions, and footprint. The only difference is the packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). PCB placement and soldering characteristics are equivalent.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on a reel, optimized for automated high-speed pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging provides components on shorter tape segments or alternative reel formats, suitable for lower-volume production, prototyping, and manual assembly processes.

Q: Are there any electrical performance differences between these two part numbers?

A: No. Both parts are manufactured to identical specifications: 15 mOhms ±1% resistance, 0.5W power rating, ±75 ppm/°C temperature coefficient, and -65°C to 170°C operating range. Electrical performance is equivalent.

Q: Which part should be selected for RoHS3 compliant applications?

A: The WSL2010R0150FEB is ROHS3 Compliant and REACH Unaffected. For designs requiring RoHS3 compliance, this part number must be used. The WSL2010R0150FTB is RoHS non-compliant and REACH Affected.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 qualification and are rated for automotive use. They are designed for current sensing applications and include features for moisture resistance and pulse withstanding in automotive environments.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the assembly process accommodates the packaging format. If your production line uses automated pick-and-place equipment, use the Tape & Reel format (WSL2010R0150FTB). If your process uses manual assembly or lower-volume production, the Cut Tape & Digi-Reel® format (WSL2010R0150FEB) is appropriate. Both deliver identical component performance.
