Substitute Part Grouping Explanation

Substitution eligibility for the WSL2512R5000FBA is determined by strict equivalence across the following critical parameters:

• Resistance value: 500 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package / Case: 2512 (6432 Metric)
• Composition: Metal Element
• Temperature coefficient: ±75ppm/°C
• Operating temperature range: -65°C ~ 170°C
• AEC-Q200 automotive qualification
• Termination count: 2
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute part WSL2512R5000FEK meets all electrical and mechanical parameters required for direct substitution. Differences exist only in packaging format (Bulk) and regulatory compliance status (RoHS3 Compliant vs. RoHS non-compliant for the main part).

Parameter Comparison

Engineering Selection Recommendations

Both WSL2512R5000FBA and WSL2512R5000FEK are functionally equivalent for current sense applications in automotive circuits. Selection between these parts should be based on regulatory and compliance requirements:

WSL2512R5000FBA is suitable for applications where RoHS non-compliance is acceptable and REACH-affected material status does not present supply chain constraints.

WSL2512R5000FEK is the preferred choice for designs requiring RoHS3 compliance and REACH-unaffected material status. This part eliminates regulatory compliance concerns in regions with strict environmental regulations.

Both parts maintain identical electrical performance, thermal characteristics, and mechanical compatibility within the 2512 package footprint.

Frequently Asked Questions (FAQ)

Q: Can WSL2512R5000FEK be used as a direct replacement for WSL2512R5000FBA?

A: Yes. Both parts are electrically and mechanically identical. They share the same resistance value (500 mOhms), tolerance (±1%), power rating (1W), package (2512), temperature coefficient (±75ppm/°C), and operating range (-65°C ~ 170°C). The primary difference is regulatory compliance status.

Q: What is the difference between these two part numbers?

A: The WSL2512R5000FEK is RoHS3 compliant and REACH unaffected, while the WSL2512R5000FBA is RoHS non-compliant and REACH affected. All electrical and mechanical specifications are identical.

Q: Are there any package or footprint differences?

A: No. Both parts use the 2512 (6432 Metric) package with identical dimensions: 0.250" L x 0.125" W (6.35mm x 3.18mm) and maximum seated height of 0.035" (0.89mm). PCB layout and assembly processes remain unchanged.

Q: Which part should I specify for new designs?

A: Selection depends on your regulatory requirements. For designs requiring RoHS3 and REACH compliance, specify WSL2512R5000FEK. For applications without these constraints, either part is acceptable based on availability and cost considerations.

Q: Are both parts AEC-Q200 qualified?

A: Yes. Both WSL2512R5000FBA and WSL2512R5000FEK carry AEC-Q200 automotive qualification and are suitable for automotive current sense applications.
