Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RAVF164DFT330R is determined by strict alignment of the following critical parameters:

• Resistance value: 330 Ohm (exact match required)
• Tolerance: ±1% (exact match required)
• Number of resistors: 4 (exact match required)
• Circuit type: Isolated (exact match required)
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals (exact match required)
• Number of pins: 8 (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Mounting type: Surface Mount (exact match required)
• RoHS compliance: ROHS3 Compliant (required for regulatory alignment)

The CAY16-3300F4LF from Bourns Inc. meets all mandatory substitution criteria. Variations in power per element and maximum operating temperature are secondary parameters that do not prevent functional substitution when application requirements are within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RAVF164DFT330R and CAY16-3300F4LF are active production components with ROHS3 compliance and unlimited moisture sensitivity ratings, making them suitable for equivalent substitution in applications where the operating temperature does not exceed 125°C and power dissipation per element does not exceed 62.5mW. The RAVF164DFT330R provides higher power handling capability (100mW per element) and extended temperature range operation (-55°C to 155°C), making it the preferred choice for high-temperature or high-power applications. The CAY16-3300F4LF is a valid substitute for standard-temperature applications within its specified operating range. Component selection should be based on application-specific thermal and power requirements.

Frequently Asked Questions (FAQ)

Q: Can the CAY16-3300F4LF replace the RAVF164DFT330R in all applications?

A: The CAY16-3300F4LF is functionally equivalent for applications where operating temperature remains below 125°C and power dissipation per resistor element does not exceed 62.5mW. Applications requiring operation above 125°C or higher power dissipation require the RAVF164DFT330R.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 1206 (3216 Metric) package with identical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum seated height of 0.024" (0.60mm). Both feature convex, long side terminals and are compatible with identical PCB layouts.

Q: Do both parts meet automotive qualification requirements?

A: The RAVF164DFT330R carries AEC-Q200 automotive qualification. The CAY16-3300F4LF does not list automotive applications in the provided specifications. Automotive applications should use the RAVF164DFT330R unless the CAY16-3300F4LF is verified for the specific automotive standard required.

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

A: The temperature coefficient indicates resistance value drift with temperature changes. Both parts maintain identical temperature stability at ±200ppm/°C, ensuring predictable performance across the specified operating temperature ranges of each component.

Q: Are there any differences in pin configuration or circuit topology?

A: No. Both parts are 8-pin isolated 4-resistor networks with identical pin counts and isolated circuit topology, ensuring direct functional equivalence in circuit design.
