Substitute Part Grouping Explanation

Substitution eligibility for the WSL2010R0200FTB is determined by strict equivalence across the following critical parameters:

• Resistance value: 20 mOhms
• Tolerance: ±1%
• Power rating: 0.5W / 1/2W
• 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
• Functional features: Current Sense, Moisture Resistant, Pulse Withstanding
• Physical dimensions and termination count

The WSL2010R0200FEB meets all substitution criteria and is classified as a direct equivalent. Differences in packaging configuration (Tape & Reel format) and regulatory compliance status do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both WSL2010R0200FTB and WSL2010R0200FEB are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts may be influenced by regulatory compliance requirements and supply chain considerations.

The WSL2010R0200FEB carries RoHS3 compliance and REACH Unaffected status, whereas the WSL2010R0200FTB is RoHS non-compliant and REACH Affected. For applications subject to RoHS or REACH regulations, WSL2010R0200FEB is the appropriate selection. Both parts maintain AEC-Q200 automotive qualification and are suitable for current sense applications requiring high reliability in temperature-extreme environments.

Frequently Asked Questions (FAQ)

Q: Can WSL2010R0200FEB be used as a direct replacement for WSL2010R0200FTB?

A: Yes. Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, package dimensions, and operating specifications. The primary difference is regulatory compliance status.

Q: What is the significance of the different part number suffixes (FTB vs. FEB)?

A: The suffix designates different manufacturing batches or packaging configurations. Both maintain identical functional specifications and are interchangeable in circuit applications.

Q: Are there any PCB layout or thermal management differences between these substitutes?

A: No. Both parts share identical physical dimensions (0.200" L × 0.100" W, 0.035" max height), termination count, and thermal characteristics. PCB footprints and thermal design considerations remain unchanged.

Q: Which part should be selected for RoHS-compliant applications?

A: WSL2010R0200FEB is RoHS3 compliant and REACH Unaffected, making it the appropriate choice for applications requiring regulatory compliance with European environmental directives.

Q: Is the 2010 package format the same as 5025 Metric?

A: Yes. 2010 and 5025 Metric are equivalent designations for the same package format, representing 0.200" × 0.100" (5.08mm × 2.54mm) dimensions.

Q: What is the Moisture Sensitivity Level (MSL) rating, and does it affect storage?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard component storage practices apply without special humidity control requirements.
