Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RAVF164DFT2K20 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.2k Ohm
• Tolerance: ±1%
• Number of resistors: 4
• Circuit type: Isolated
• Number of pins: 8
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals
• Mounting type: Surface Mount
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Height - Seated (Max): 0.024" (0.60mm)

Allowable Variation Parameters:

• Power Per Element: May be lower than the original specification
• Operating Temperature Range: May be narrower than the original specification
• Temperature Coefficient: Must remain ±200ppm/°C

The CAY16-2201F4LF from Bourns Inc. meets all mandatory matching parameters and qualifies as a direct substitute despite having a reduced power per element rating (62.5mW versus 100mW) and a narrower operating temperature range (-55°C ~ 125°C versus -55°C ~ 155°C).

Parameter Comparison

Engineering Selection Recommendations

Both the RAVF164DFT2K20 and CAY16-2201F4LF are active production components with ROHS3 compliance and MSL Level 1 rating. The primary distinction between these parts is the power dissipation capability and maximum operating temperature.

The RAVF164DFT2K20 provides 100mW per element and operates to 155°C, making it suitable for high-temperature automotive applications. The CAY16-2201F4LF provides 62.5mW per element with operation limited to 125°C. Selection between these parts depends on the thermal and power requirements of the specific application circuit. Both parts maintain identical electrical characteristics in resistance value, tolerance, and temperature coefficient, ensuring functional equivalence in circuits operating within the CAY16-2201F4LF's thermal envelope.

Frequently Asked Questions (FAQ)

Q: Can the CAY16-2201F4LF replace the RAVF164DFT2K20 in all applications?

A: The CAY16-2201F4LF is electrically and mechanically compatible with the RAVF164DFT2K20 provided the application does not require operation above 125°C or power dissipation exceeding 62.5mW per resistor element. Verify that your circuit's thermal and power requirements fall within the CAY16-2201F4LF specifications before substitution.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 1206 (3216 Metric) package with identical length (0.126"), width (0.063"), and maximum seated height (0.024"). They are mechanically interchangeable on PCBs designed for either component.

Q: What is the significance of the isolated circuit type?

A: The isolated circuit type indicates that each of the four resistors in the array is electrically independent with no internal connections between elements. This configuration allows flexible circuit design where each resistor can be used independently or in various network configurations.

Q: Do both parts meet automotive qualification standards?

A: The RAVF164DFT2K20 carries AEC-Q200 automotive qualification. The CAY16-2201F4LF specifications provided do not explicitly state AEC-Q200 qualification. Verify automotive qualification requirements with the manufacturer if this is a critical application parameter.

Q: What does MSL Level 1 mean for these components?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life with no moisture bake requirement prior to soldering. These components can be stored and handled under standard conditions without special moisture control procedures.
