Substitute Part Grouping Explanation

Substitution eligibility for the RAVF164DFT470R is determined by the following critical parameters:

• Resistance value: 470 Ohm
• Tolerance: ±1%
• Circuit configuration: Isolated 4-resistor network
• Number of pins: 8
• Temperature coefficient: ±200ppm/°C
• Package type: 1206 (3216 Metric), Convex, Long Side Terminals
• Mounting: Surface Mount
• Compliance: ROHS3 and REACH requirements

The identified substitute CAY16-4700F4LF from Bourns Inc. matches all critical electrical and mechanical parameters. Differences in power per element rating and maximum operating temperature do not preclude substitution when application requirements are within the substitute's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RAVF164DFT470R and CAY16-4700F4LF are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts should be based on application-specific power dissipation requirements and operating temperature constraints. The RAVF164DFT470R supports operation to 155°C with 100mW per element power rating, while the CAY16-4700F4LF operates to 125°C maximum with 62.5mW per element. Both components maintain identical electrical characteristics in resistance, tolerance, and temperature coefficient, ensuring functional interchangeability within their respective thermal and power envelopes.

Frequently Asked Questions (FAQ)

Q: Can CAY16-4700F4LF replace RAVF164DFT470R in all applications?

A: Substitution is valid when application requirements do not exceed the CAY16-4700F4LF specifications. Verify that circuit power dissipation per resistor element does not exceed 62.5mW and that maximum operating temperature does not exceed 125°C.

Q: What are the key differences between these parts?

A: The primary differences are power per element rating (100mW vs. 62.5mW) and maximum operating temperature (155°C vs. 125°C). All other electrical and mechanical parameters are identical.

Q: Are the packages physically identical?

A: Yes. Both components use the 1206 (3216 Metric) package with convex, long side terminals. PCB footprints and reflow profiles are compatible.

Q: Do both parts meet automotive qualification requirements?

A: The RAVF164DFT470R carries AEC-Q200 automotive qualification. The CAY16-4700F4LF is active production with ROHS3 compliance. Verify specific automotive qualification requirements for your application.

Q: Are there any compliance differences?

A: Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both components.
