Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WSR2R0200FBA is determined by strict equivalence across the following critical parameters:

• Resistance value: 20 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package type: 4527 J-Lead
• Composition: Metal Element
• Temperature coefficient: ±75ppm/°C
• Operating temperature range: -65°C ~ 275°C
• Automotive qualification: AEC-Q200
• Feature set: Anti-sulfur, current sense, moisture resistant, pulse withstanding

The WSR2R0200FEK meets all these criteria and is classified as a direct manufacturer equivalent. Both parts are produced by Vishay Dale within the WSR series and maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The WSR2R0200FEK is a direct functional equivalent to the WSR2R0200FBA. Both parts are manufactured by Vishay Dale and share identical electrical performance, mechanical dimensions, and automotive qualification status. The primary distinction is RoHS compliance: the WSR2R0200FEK is ROHS3 compliant, while the WSR2R0200FBA is RoHS non-compliant. Selection between these parts should be based on the specific regulatory and compliance requirements of the end application. For applications requiring RoHS3 compliance, the WSR2R0200FEK is the appropriate choice. For applications without RoHS compliance mandates, either part is suitable. Both parts maintain AEC-Q200 automotive qualification and are suitable for current sensing in automotive and industrial environments.

Frequently Asked Questions (FAQ)

Q: Can WSR2R0200FEK be used as a direct replacement for WSR2R0200FBA?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance values, tolerances, power ratings, package dimensions, and temperature specifications. The WSR2R0200FEK is suitable for direct substitution in any application where the WSR2R0200FBA is specified, provided RoHS compliance requirements are compatible with the end application.

Q: What is the difference between these two parts?

A: The primary difference is RoHS compliance status. The WSR2R0200FEK is ROHS3 compliant, while the WSR2R0200FBA is RoHS non-compliant. All other electrical, mechanical, and performance characteristics are identical.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 4527 J-Lead package with identical dimensions of 0.455" L x 0.275" W (11.56mm x 6.98mm) and a maximum seated height of 0.100" (2.54mm). PCB layout and assembly processes require no modification when substituting between these parts.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the WSR2R0200FBA and WSR2R0200FEK are AEC-Q200 qualified and suitable for automotive applications. Both feature anti-sulfur coating, moisture resistance, and pulse withstanding capability.

Q: Which part should I select for a new design?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, specify the WSR2R0200FEK. For applications without RoHS compliance mandates, either part is acceptable. Consult your application's compliance documentation to determine the appropriate choice.
