Engineering Selection Recommendations
The CAY16-33R0F4LF is an active, production-status equivalent suitable for direct substitution in applications where the operating temperature range does not exceed 125°C and power dissipation per element does not exceed 62.5mW. Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and identical mechanical footprints. Selection between these parts should be based on application thermal requirements and available inventory.
Frequently Asked Questions (FAQ)
Q: Can CAY16-33R0F4LF replace RAVF164DFT33R0 in all applications?
A: CAY16-33R0F4LF is suitable for substitution in applications operating within -55°C to 125°C and with power dissipation not exceeding 62.5mW per element. Applications requiring operation above 125°C or higher power dissipation require the RAVF164DFT33R0.
Q: Are the physical dimensions identical?
A: Yes. Both parts use the 1206 (3216 Metric) package 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).
Q: Do both parts have the same pin configuration?
A: Yes. Both parts feature 8 pins in an isolated 4-resistor network configuration with identical pinout.
Q: What is the difference in power rating?
A: The RAVF164DFT33R0 supports 100mW per element, while the CAY16-33R0F4LF supports 62.5mW per element. Applications with higher power dissipation requirements must use the RAVF164DFT33R0.
Q: Are both parts automotive-grade?
A: The RAVF164DFT33R0 carries AEC-Q200 automotive qualification. The CAY16-33R0F4LF specifications provided do not indicate automotive qualification status.
Q: What is the temperature coefficient match?
A: Both parts feature ±200ppm/°C temperature coefficient, ensuring matched thermal performance characteristics.
