Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2010FTR680 is determined by the following critical parameters:

• Electrical Match: Resistance value (680 mOhms), tolerance (±1%), and power rating (1W) must be identical
• Package Compatibility: 2010 (5025 Metric) package with matching physical dimensions and termination count (2 terminations)
• Composition & Function: Thick film construction with current sense capability
• Operating Range: Temperature range of -55°C to 155°C or wider
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status required

The RCWE2010R680FKEA from Vishay Dale meets all substitution criteria while offering enhanced specifications in temperature coefficient and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The RCWE2010R680FKEA qualifies as a direct substitute for the CSRN2010FTR680 based on matching electrical specifications, identical package dimensions, and equivalent regulatory compliance. Both components are Active status products with ROHS3 certification and unlimited moisture sensitivity rating.

The RCWE2010R680FKEA provides enhanced performance characteristics through a superior temperature coefficient (±100ppm/°C versus ±250ppm/°C) and includes automotive AEC-Q200 qualification with moisture-resistant construction. Physical dimensions remain compatible within standard PCB assembly tolerances, with the substitute measuring 0.028" maximum height compared to 0.030" for the original part.

Selection between these components depends on application requirements: the CSRN2010FTR680 is suitable for general industrial current sensing applications, while the RCWE2010R680FKEA is specified for automotive and high-reliability environments requiring AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can RCWE2010R680FKEA replace CSRN2010FTR680 in existing designs?

A: Yes. Both components share identical resistance (680 mOhms), tolerance (±1%), power rating (1W), and 2010 package specification. Physical dimensions are compatible within standard PCB assembly tolerances.

Q: What is the significance of the temperature coefficient difference?

A: The RCWE2010R680FKEA exhibits ±100ppm/°C compared to ±250ppm/°C for the CSRN2010FTR680. This represents improved temperature stability, resulting in more consistent resistance values across the -55°C to 155°C operating range. Both values are within acceptable ranges for current sense applications.

Q: Does the AEC-Q200 rating on the substitute part affect compatibility?

A: No. AEC-Q200 is an automotive qualification standard that indicates enhanced reliability testing and quality assurance. It does not affect electrical or mechanical compatibility. Applications not requiring automotive qualification can use either part.

Q: Are the physical dimension variations significant?

A: Dimension variations are minimal and within standard PCB assembly tolerances. The substitute measures 0.098" width (versus 0.097") and 0.028" height (versus 0.030"). These differences do not impact PCB layout or assembly processes.

Q: What regulatory compliance applies to both parts?

A: Both components are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is 1 (Unlimited) for both parts, indicating no special moisture handling requirements during storage or assembly.
