Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RAVF164DFT51R0 is determined by the following critical parameters:

• Resistance value: 51 Ohm (exact match required)
• Tolerance: ±1% (exact match required)
• Number of resistors: 4 (exact match required)
• Circuit type: Isolated (exact match required)
• Package / Case: 1206 (3216 Metric), Convex, Long Side Terminals (exact match required)
• Number of pins: 8 (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

The CAY16-51R0F4LF from Bourns Inc. meets all critical electrical and mechanical parameters. 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 RAVF164DFT51R0 and CAY16-51R0F4LF are active production components with full RoHS3 compliance and identical electrical and mechanical specifications for core parameters. Selection between these parts should be based on application-specific power dissipation requirements and operating temperature limits. The RAVF164DFT51R0 supports higher power per element (100mW versus 62.5mW) and extended operating temperature range (-55°C to 155°C versus -55°C to 125°C). The CAY16-51R0F4LF is suitable for applications operating within -55°C to 125°C with power dissipation not exceeding 62.5mW per element. Both components maintain identical dimensional footprints and pin configurations, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CAY16-51R0F4LF replace the RAVF164DFT51R0 in all applications?

A: The CAY16-51R0F4LF is a direct substitute provided the application operates within -55°C to 125°C and power dissipation per element does not exceed 62.5mW. If your application requires operation above 125°C or dissipates more than 62.5mW per element, the RAVF164DFT51R0 is required.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 1206 (3216 Metric) with identical length (0.126"), width (0.063"), and maximum seated height (0.024"). PCB footprints are directly compatible.

Q: Do both parts have the same pin configuration?

A: Yes. Both parts feature 8 pins in an isolated 4-resistor network configuration with identical terminal placement and spacing.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH unaffected. The RAVF164DFT51R0 includes AEC-Q200 automotive qualification; verify whether your application requires this certification.

Q: What is the primary difference between these substitute parts?

A: The RAVF164DFT51R0 provides higher power per element (100mW) and extended temperature range (-55°C to 155°C). The CAY16-51R0F4LF operates at 62.5mW per element with a maximum temperature of 125°C. Electrical characteristics (resistance, tolerance, temperature coefficient) are identical.
