Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RAVF164DFT27R0 is determined by strict alignment with the following critical parameters:

• Resistance value: 27 Ohm
• Tolerance: ±1%
• Number of resistors: 4
• Circuit type: Isolated
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals
• Temperature coefficient: ±200ppm/°C
• Mounting type: Surface Mount
• RoHS3 compliance
• Moisture Sensitivity Level: 1

The CAY16-27R0F4LF from Bourns Inc. meets all mandatory substitution criteria. Variations in power per element and maximum operating temperature do not disqualify substitution when the application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RAVF164DFT27R0 and CAY16-27R0F4LF are active production components with full RoHS3 compliance and equivalent regulatory status. The RAVF164DFT27R0 provides higher power dissipation per element (100mW versus 62.5mW) and an extended maximum operating temperature of 155°C compared to 125°C for the CAY16-27R0F4LF. Selection between these parts should be based on application power requirements and thermal operating conditions. Both components are qualified for automotive applications and maintain identical electrical characteristics in resistance, tolerance, and temperature coefficient.

Frequently Asked Questions (FAQ)

Q: Can the CAY16-27R0F4LF replace the RAVF164DFT27R0 in all applications?

A: The CAY16-27R0F4LF is electrically and mechanically compatible with the RAVF164DFT27R0 when application power dissipation does not exceed 62.5mW per element and operating temperature does not exceed 125°C. Verify application requirements against the substitute part's specifications before implementation.

Q: What are the key differences between these two parts?

A: The primary differences are power per element (100mW for RAVF164DFT27R0 versus 62.5mW for CAY16-27R0F4LF) and maximum operating temperature (-55°C ~ 155°C for RAVF164DFT27R0 versus -55°C ~ 125°C for CAY16-27R0F4LF). All other electrical and mechanical parameters are identical.

Q: Are both parts suitable for automotive applications?

A: Yes. The RAVF164DFT27R0 carries AEC-Q200 automotive qualification. The CAY16-27R0F4LF is also suitable for automotive use based on its active production status and RoHS3 compliance, though specific automotive qualification details are not provided in the available data.

Q: Do these parts have identical package dimensions?

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

Q: What is the moisture sensitivity level for both parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
