Substitute Part Grouping Explanation

Substitution eligibility for the RAVF164DFT680R is determined by the following critical parameters:

• Resistance value: 680 Ohm
• Tolerance: ±1%
• Circuit configuration: Isolated 4-resistor network
• Package format: 1206 (3216 Metric) with convex, long side terminals
• Pin count: 8
• Temperature coefficient: ±200ppm/°C
• Surface mount compatibility
• RoHS3 compliance

The CAY16-6800F4LF from Bourns Inc. meets all primary electrical and mechanical substitution criteria. Differences in power per element rating and maximum operating temperature are noted in the parameter comparison and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RAVF164DFT680R and CAY16-6800F4LF are active production components with ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts depends on application-specific thermal and power dissipation requirements.

The RAVF164DFT680R supports higher power per element (100mW) and extended operating temperature range to 155°C, making it suitable for high-temperature automotive and industrial applications requiring maximum thermal headroom.

The CAY16-6800F4LF operates within a reduced temperature range (-55°C to 125°C) with lower power per element (62.5mW), appropriate for applications where thermal constraints are less demanding.

Both components share identical electrical characteristics (680 Ohm, ±1%, ±200ppm/°C) and mechanical compatibility (1206 package, 8-pin isolated configuration), ensuring functional interchangeability within their respective thermal and power operating windows.

Frequently Asked Questions (FAQ)

Q: Can the CAY16-6800F4LF replace the RAVF164DFT680R in all applications?

A: Functional replacement is possible where operating temperatures remain below 125°C and power dissipation per element does not exceed 62.5mW. Applications requiring the full -55°C to 155°C temperature range or higher power ratings require the RAVF164DFT680R.

Q: Are the package dimensions identical between these parts?

A: Yes. Both components use the 1206 (3216 Metric) package with convex, long side terminals. Physical dimensions (0.126" L x 0.063" W, 0.024" max height) and pin configuration (8-pin isolated) are identical, ensuring PCB layout compatibility.

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

A: The temperature coefficient defines resistance drift over the operating temperature range. Both parts maintain ±200ppm/°C stability, ensuring consistent electrical performance across their respective temperature ranges.

Q: Are both parts suitable for automotive applications?

A: The RAVF164DFT680R carries AEC-Q200 automotive qualification. The CAY16-6800F4LF is active production with ROHS3 compliance but does not specify AEC-Q200 qualification in the provided data. Automotive applications requiring formal qualification should confirm the CAY16-6800F4LF's qualification status with the manufacturer.

Q: What does "Isolated" circuit type mean?

A: Isolated configuration means each of the four resistors operates independently with no internal connections between elements, allowing flexible circuit design and independent biasing of each resistor network.
