Substitute Part Grouping Explanation
Substitution eligibility for the RAVF164DFT47R0 is determined by strict equivalence across the following critical parameters:
- Resistance value: 47 Ohm
- Tolerance: ±1%
- Number of resistors: 4
- Circuit configuration: Isolated
- Pin count: 8
- Temperature coefficient: ±200ppm/°C
- Package type: 1206 (3216 Metric) with convex, long side terminals
- Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
- Height: 0.024" (0.60mm) maximum seated height
- Compliance: RoHS3 compliant, MSL 1
The CAY16-47R0F4LF from Bourns Inc. meets all these criteria and is classified as a manufacturer-recommended substitute. Variations in power per element rating do not affect substitution eligibility when the component operates within the thermal constraints of the application circuit.

Engineering Selection Recommendations
Both the RAVF164DFT47R0 and CAY16-47R0F4LF are active production components with full RoHS3 compliance and unlimited moisture sensitivity ratings, making them suitable for long-term supply chain planning.
The primary distinction between these parts is the operating temperature range and power per element rating. The RAVF164DFT47R0 supports operation to 155°C with 100mW per element, while the CAY16-47R0F4LF operates to 125°C with 62.5mW per element. Selection between these parts depends on the specific thermal requirements of the application circuit. Applications requiring operation above 125°C or higher power dissipation per resistor element must use the RAVF164DFT47R0. Applications operating within the -55°C to 125°C range with power dissipation not exceeding 62.5mW per element can use either part interchangeably.
Both components carry identical electrical specifications (47 Ohm, ±1% tolerance, ±200ppm/°C temperature coefficient) and mechanical compatibility (1206 package, 8-pin isolated configuration, identical physical dimensions).
Frequently Asked Questions (FAQ)
Q: Can the CAY16-47R0F4LF replace the RAVF164DFT47R0 in all applications?
A: The CAY16-47R0F4LF is electrically and mechanically compatible with the RAVF164DFT47R0 for applications operating within -55°C to 125°C with power dissipation not exceeding 62.5mW per resistor element. Applications requiring operation above 125°C or higher power dissipation must use the RAVF164DFT47R0.
Q: Are the physical dimensions identical between these parts?
A: Yes. Both parts use the 1206 (3216 Metric) package with convex, long side terminals. Dimensions are 0.126" L x 0.063" W (3.20mm x 1.60mm) with a maximum seated height of 0.024" (0.60mm). They are mechanically interchangeable on PCB layouts.
Q: Do both parts meet automotive compliance requirements?
A: The RAVF164DFT47R0 is specified for automotive AEC-Q200 applications. The CAY16-47R0F4LF does not list automotive applications in the provided specifications. Automotive applications must use the RAVF164DFT47R0.
Q: What is the difference in power rating between these parts?
A: The RAVF164DFT47R0 is rated at 100mW per element, while the CAY16-47R0F4LF is rated at 62.5mW per element. This difference affects maximum allowable current and thermal performance in high-power applications.
