Substitute Part Grouping Explanation

Substitution eligibility for the CSR0805FKR430 is determined by the following criteria:

• Resistance value: 430 mOhms
• Tolerance: ±1%
• Power rating: 0.25W minimum
• Package type: 0805 (2012 Metric)
• Composition: Thick film
• Operating temperature range: -55°C to 155°C minimum
• Compliance: ROHS3 and REACH requirements
• Moisture sensitivity: MSL 1 or better

The RCWE0805R430FKEA from Vishay Dale meets all substitution criteria while providing additional automotive qualification (AEC-Q200) and moisture-resistant characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the CSR0805FKR430 and RCWE0805R430FKEA are active production parts meeting ROHS3 and REACH compliance requirements. The Stackpole CSR0805FKR430 is suitable for general current sense applications with standard environmental conditions. The Vishay Dale RCWE0805R430FKEA provides automotive-grade qualification (AEC-Q200) with improved temperature coefficient performance (±100ppm/°C versus ±200ppm/°C), making it appropriate for automotive and high-reliability applications requiring tighter thermal stability. Both parts share identical electrical specifications, package dimensions within tolerance, and moisture sensitivity ratings, ensuring direct functional interchangeability in 0805 form factor designs.

Frequently Asked Questions (FAQ)

Q: Can RCWE0805R430FKEA replace CSR0805FKR430 in all applications?

A: Yes, the RCWE0805R430FKEA meets or exceeds all electrical and mechanical parameters of the CSR0805FKR430. The improved temperature coefficient and AEC-Q200 qualification provide additional performance margin without compromising compatibility.

Q: What is the significance of the AEC-Q200 rating on the Vishay part?

A: AEC-Q200 is an automotive industry qualification standard. This certification indicates the part has undergone rigorous testing for automotive applications. It is not required for non-automotive use but provides additional assurance of reliability and consistency.

Q: Are the physical dimensions identical between these parts?

A: Both parts conform to the 0805 (2012 Metric) package standard with maximum height of 0.026" (0.65mm). Width differs by 0.002" (0.05mm), which is within standard package tolerance and does not affect PCB layout or assembly compatibility.

Q: What does the temperature coefficient difference mean?

A: The CSR0805FKR430 has a temperature coefficient of ±200ppm/°C, while the RCWE0805R430FKEA has ±100ppm/°C. This means the Vishay part's resistance value changes less with temperature variations, providing better stability in applications with wide operating temperature ranges.

Q: Are both parts available in the same packaging format?

A: Yes, both parts are supplied in Tape & Reel (TR) format suitable for automated assembly processes.
