Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RAVF164DFT12K0 is determined by the following critical parameters:

• Resistance value: 12kΩ
• Tolerance: ±1%
• Number of resistors: 4
• Circuit type: Isolated
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals
• Number of pins: 8
• Temperature coefficient: ±200ppm/°C
• 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)

The CAY16-1202F4LF from Bourns Inc. meets all critical substitution criteria. Both parts share identical resistance, tolerance, circuit configuration, package type, pin count, temperature coefficient, and physical dimensions. Differences in power per element rating and maximum operating temperature do not preclude substitution when application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RAVF164DFT12K0 and CAY16-1202F4LF are active production components with ROHS3 compliance and unlimited moisture sensitivity rating. The RAVF164DFT12K0 carries AEC-Q200 automotive qualification, while the CAY16-1202F4LF does not list this certification in the provided specifications. Selection between these parts should be based on application requirements regarding power dissipation per element (100mW versus 62.5mW) and maximum operating temperature (155°C versus 125°C). For applications operating above 125°C or requiring the higher power rating, the RAVF164DFT12K0 is the appropriate choice. For applications within the CAY16-1202F4LF operating range, either part is electrically and mechanically compatible.

Frequently Asked Questions (FAQ)

Q: Can the CAY16-1202F4LF replace the RAVF164DFT12K0 in all applications?

A: Electrical and mechanical compatibility is confirmed. Substitution is valid when application operating temperature does not exceed 125°C and power dissipation per element does not exceed 62.5mW. Applications requiring higher temperature operation or power ratings require the RAVF164DFT12K0.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are packaged in 1206 (3216 Metric) with convex, long side terminals. Dimensions are 0.126" L x 0.063" W (3.20mm x 1.60mm) with maximum seated height of 0.024" (0.60mm). PCB layout and assembly compatibility are identical.

Q: What is the significance of the power per element difference?

A: The RAVF164DFT12K0 is rated at 100mW per element, while the CAY16-1202F4LF is rated at 62.5mW per element. This difference affects maximum allowable power dissipation in each resistor. Applications with higher power requirements must use the RAVF164DFT12K0.

Q: Do both parts have the same temperature coefficient?

A: Yes. Both parts have a temperature coefficient of ±200ppm/°C, ensuring equivalent thermal stability across the operating range.

Q: Are both parts RoHS compliant?

A: Yes. Both the RAVF164DFT12K0 and CAY16-1202F4LF are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).
