Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RAVF164DFT300R is determined by the following critical parameters:

• Resistance value: 300 Ohm
• Tolerance: ±1%
• Circuit configuration: Isolated 4-resistor network
• Package footprint: 1206 (3216 Metric) with convex, long side terminals
• Pin count: 8
• Temperature coefficient: ±200ppm/°C
• Surface mount compatibility
• RoHS3 compliance

The CAY16-3000F4LF meets all primary electrical and mechanical substitution criteria. Differences in power per element and maximum operating temperature represent design trade-offs that must be evaluated within specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RAVF164DFT300R and CAY16-3000F4LF are active production components with ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts should be based on application-specific thermal and power dissipation requirements. The RAVF164DFT300R provides higher power per element (100mW) and extended operating temperature range to 155°C, suitable for high-temperature automotive environments. The CAY16-3000F4LF operates to 125°C with 62.5mW per element, appropriate for standard automotive and industrial applications within this temperature envelope. Both components maintain identical electrical specifications (300 Ohm ±1%, ±200ppm/°C) and mechanical compatibility in 1206 surface mount packages.

Frequently Asked Questions (FAQ)

Q: Can CAY16-3000F4LF replace RAVF164DFT300R in all applications?

A: Electrical and mechanical compatibility is confirmed. Thermal performance differs: CAY16-3000F4LF is rated to 125°C maximum versus 155°C for RAVF164DFT300R. Applications operating above 125°C require the RAVF164DFT300R. Power dissipation per element is lower in the CAY16-3000F4LF (62.5mW vs 100mW), which may affect designs with high current density requirements.

Q: Are the package footprints identical?

A: Yes. Both components use 1206 (3216 Metric) packages with convex, long side terminals. Physical dimensions and PCB land patterns are identical: 0.126" L x 0.063" W (3.20mm x 1.60mm) with 0.024" (0.60mm) maximum seated height.

Q: Do both parts meet automotive qualification requirements?

A: RAVF164DFT300R carries AEC-Q200 qualification. CAY16-3000F4LF product status is listed as active with ROHS3 compliance. Specific automotive qualification status for the CAY16-3000F4LF should be confirmed with Bourns documentation for applications requiring explicit AEC-Q200 certification.

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

A: Both parts maintain identical temperature coefficient specifications. This parameter defines resistance drift over the operating temperature range and is critical for precision analog circuits. The matching specification ensures predictable behavior across -55°C to 125°C (CAY16-3000F4LF) or -55°C to 155°C (RAVF164DFT300R).

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage practices apply without special desiccant or baking requirements.
