Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WSL2010R1000FBA is determined by the following critical parameters:

• Resistance Value: Must be 0.1 ohm (100 mOhms) with ±1% tolerance
• Package Type: Must be 2010 (5025 metric) for PCB footprint compatibility
• Number of Terminations: Must be 2-terminal configuration
• Moisture Sensitivity Level: Must be MSL 1 or equivalent
• Power Rating: Must meet or exceed 0.5W minimum dissipation requirement
• Temperature Range: Must cover or exceed the -65°C to 170°C operating window

The substitute part HVCB2010FKC100M from Stackpole Electronics Inc meets these core substitution criteria. While composition differs (thick film vs. metal element) and some secondary parameters vary, the electrical and mechanical compatibility parameters align within acceptable substitution boundaries for this resistor category.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (WSL2010R1000FBA): Select when AEC-Q200 automotive qualification is a mandatory requirement or when the extended operating temperature range (-65°C to 170°C) is necessary for the application. Metal element composition provides specific performance characteristics for current sense applications in automotive environments.

Substitute Part (HVCB2010FKC100M): Select when ROHS3 compliance is required and the operating temperature range of -55°C to 150°C is acceptable for the application. The higher power rating (1W vs. 0.5W) provides additional thermal margin. Note that this substitute does not carry AEC-Q200 qualification; applications requiring automotive certification must use the primary part.

Both parts maintain identical resistance, tolerance, package footprint, and moisture sensitivity classification, ensuring mechanical and electrical interchangeability within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can HVCB2010FKC100M be used as a direct replacement for WSL2010R1000FBA in automotive applications?

A: Direct replacement is not recommended for applications requiring AEC-Q200 certification. The substitute part does not carry this automotive qualification. For non-certified applications, substitution is permissible if the operating temperature range of -55°C to 150°C meets system requirements.

Q: What is the impact of the different composition (metal element vs. thick film)?

A: Composition differences affect performance characteristics such as temperature coefficient stability and frequency response. The substitute's thick film construction provides a lower temperature coefficient (±50 ppm/°C vs. ±75 ppm/°C), resulting in better resistance stability across temperature variations.

Q: Are the packages physically identical?

A: Yes. Both parts use the 2010 (5025 metric) package with identical footprint dimensions (0.200" L x 0.100" W / 5.08mm x 2.54mm). PCB layout compatibility is maintained.

Q: Does the higher power rating of the substitute part affect circuit performance?

A: The 1W rating of HVCB2010FKC100M exceeds the 0.5W requirement of the main part. This provides additional thermal headroom but does not alter electrical performance in the circuit. The resistor will dissipate the same power as designed; the higher rating simply indicates greater thermal capacity.

Q: What is the significance of RoHS compliance difference?

A: The main part is RoHS non-compliant while the substitute is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the substitute part satisfies compliance mandates. Non-regulated applications may use either part.

Q: Can these parts be mixed in the same production batch?

A: Mixing is not recommended due to differences in composition, temperature coefficient, and certifications. Maintain part consistency within a single assembly or production lot to ensure uniform performance characteristics.
