Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSR1206FTR470 is determined by the following critical parameters:

Resistance value and tolerance must match exactly at 470 mOhms ±1%. Power rating must be equivalent or greater at 0.5W minimum. Package designation must be identical: 1206 (3216 Metric). Temperature coefficient must be ±100ppm/°C or better. Operating temperature range must encompass -55°C to 155°C. Composition must be thick film. RoHS3 compliance is required. Moisture sensitivity level must be MSL 1 or better.

The RCWE1206R470FKEA from Vishay Dale meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the CSR1206FTR470 and RCWE1206R470FKEA are active production parts with ROHS3 compliance and identical electrical specifications. The Vishay Dale RCWE1206R470FKEA carries additional AEC-Q200 automotive qualification and moisture resistant designation, making it suitable for applications requiring automotive-grade reliability. Selection between these parts should be based on application requirements, supply chain availability, and cost considerations. Both parts are functionally interchangeable in standard industrial and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can RCWE1206R470FKEA replace CSR1206FTR470 in any application?

A: Yes. Both parts share identical electrical parameters: 470 mOhms ±1% resistance, 0.5W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Package dimensions are equivalent within tolerance. The RCWE1206R470FKEA includes additional automotive qualification, which does not restrict its use in non-automotive applications.

Q: Are there dimensional differences between these parts?

A: Dimensions are within standard manufacturing tolerance. CSR1206FTR470 is specified at 0.120" L x 0.061" W (3.05mm x 1.55mm) with 0.026" maximum seated height. RCWE1206R470FKEA is specified at 0.122" L x 0.063" W (3.10mm x 1.60mm) with 0.028" maximum seated height. These variations are within typical PCB footprint design margins for 1206 packages.

Q: What is the significance of AEC-Q200 qualification on the substitute part?

A: AEC-Q200 is an automotive industry standard for discrete semiconductors and passive components. This qualification indicates the part has undergone additional reliability testing and is suitable for automotive applications. For non-automotive use, this certification provides no additional constraint and may offer enhanced reliability margins.

Q: Are both parts suitable for current sensing applications?

A: Yes. Both parts are designated as current sense resistors with thick film composition optimized for low resistance measurement. The ±1% tolerance and ±100ppm/°C temperature coefficient support precision current monitoring in power management circuits.

Q: What is MSL 1 moisture sensitivity level?

A: MSL 1 indicates unlimited moisture sensitivity level, meaning the component requires no special moisture control during storage, handling, or assembly. Both parts can be stored and processed under standard industrial conditions without desiccant packaging or baking requirements.
