Frequently Asked Questions (FAQ)

Q: Can CAY16-22R0F4LF replace RAVF164DFT22R0 in all applications?

A: Direct substitution is possible when the application operating temperature does not exceed 125°C and power dissipation per element remains at or below 62.5mW. Applications requiring operation above 125°C or higher power dissipation require the RAVF164DFT22R0.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components are packaged in 1206 (3216 Metric) with identical dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum seated height of 0.024" (0.60mm), ensuring PCB layout compatibility.

Q: What is the significance of the ±200ppm/°C temperature coefficient?

A: The temperature coefficient specifies the resistance change per degree Celsius. Both parts maintain identical temperature stability at ±200ppm/°C, ensuring consistent performance across their respective operating temperature ranges.

Q: Are both parts suitable for automotive applications?

A: The RAVF164DFT22R0 carries AEC-Q200 automotive qualification. The CAY16-22R0F4LF is active production with ROHS3 compliance. Automotive application requirements should be verified against specific qualification standards required by the end application.

Q: What does "Isolated" circuit type mean?

A: Isolated circuit type indicates that each of the four resistors in the network is electrically independent with no internal connections between resistor elements, allowing independent use of each resistor within the package.
