Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2010FTR820 is determined by the following critical parameters:

• Resistance value: 820 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2010 (5025 Metric)
• Composition: Thick Film
• Application feature: Current Sense
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The RCWE2010R820FKEA from Vishay Dale meets all these core electrical and mechanical requirements. While the temperature coefficient differs (±100ppm/°C versus ±250ppm/°C), both values fall within acceptable ranges for current sense applications. The substitute part includes additional automotive qualification (AEC-Q200) and moisture resistance features, making it suitable for applications requiring enhanced reliability.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2010FTR820 and RCWE2010R820FKEA are active production parts with ROHS3 compliance and REACH unaffected status. The RCWE2010R820FKEA offers additional automotive qualification through AEC-Q200 certification and enhanced moisture resistance, making it suitable for applications requiring higher reliability standards or automotive environments. The lower temperature coefficient of the Vishay part (±100ppm/°C) provides improved stability across temperature extremes compared to the Stackpole original (±250ppm/°C). Both parts maintain identical electrical performance in resistance, tolerance, and power rating, with negligible dimensional differences that do not affect PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can RCWE2010R820FKEA directly replace CSRN2010FTR820 in existing designs?

A: Yes. Both parts share identical resistance (820 mOhms), tolerance (±1%), power rating (1W), and 2010 package specification. Dimensional differences are minimal (width 2.45mm vs 2.50mm, height 0.75mm vs 0.70mm) and do not affect PCB footprint compatibility.

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

A: The RCWE2010R820FKEA has a lower temperature coefficient (±100ppm/°C) compared to CSRN2010FTR820 (±250ppm/°C). This means the Vishay part exhibits better resistance stability across temperature variations, which is beneficial for precision current sensing applications operating across wide temperature ranges.

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

A: No. AEC-Q200 is an automotive qualification that indicates enhanced reliability testing and quality assurance. It does not change electrical or mechanical compatibility; it only confirms the part meets automotive industry standards.

Q: Are both parts suitable for current sense applications?

A: Yes. Both the CSRN2010FTR820 and RCWE2010R820FKEA are specified as current sense thick film resistors and are designed for precision current measurement in electronic circuits.

Q: What packaging formats are available for these parts?

A: CSRN2010FTR820 is supplied in Tape & Reel (TR) format. RCWE2010R820FKEA is available in Cut Tape (CT) and Digi-Reel® formats, with Tape & Reel (TR) also listed as an option.
