Parameter Comparison

Engineering Selection Recommendations

Both the RAVF164DFT18K0 and CAY16-1802F4LF are active production components with full RoHS3 compliance and MSL 1 rating. Selection between these parts should be based on application-specific requirements:

The RAVF164DFT18K0 provides 100mW power per element and operates across -55°C to 155°C, suitable for high-temperature automotive and industrial applications requiring extended thermal range.

The CAY16-1802F4LF provides 62.5mW power per element and operates across -55°C to 125°C, suitable for standard commercial and industrial applications within the specified temperature range.

Both components are electrically and mechanically interchangeable for applications operating within the CAY16-1802F4LF temperature and power specifications. Component selection should align with the thermal and power dissipation requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Are RAVF164DFT18K0 and CAY16-1802F4LF pin-compatible?

A: Yes. Both components feature 8 pins in identical 1206 (3216 Metric) package configuration with convex, long side terminals. PCB footprints are directly interchangeable.

Q: What are the key differences between these parts?

A: The primary differences are power per element (100mW vs. 62.5mW) and maximum operating temperature (155°C vs. 125°C). All electrical parameters including resistance, tolerance, and temperature coefficient are identical.

Q: Can CAY16-1802F4LF replace RAVF164DFT18K0 in all applications?

A: CAY16-1802F4LF is suitable for applications operating within -55°C to 125°C and requiring maximum 62.5mW per element. Applications requiring higher power dissipation or extended temperature range above 125°C require the RAVF164DFT18K0.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RAVF164DFT18K0 and CAY16-1802F4LF are RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the package footprint for these resistor arrays?

A: Both components use 1206 (3216 Metric) surface mount package with dimensions 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum seated height of 0.024" (0.60mm).
