Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAY16-751J4LF is determined by strict equivalence across the following critical parameters:

• Resistance value: 750 Ohm
• Tolerance: ±5%
• Circuit configuration: Isolated 4-resistor network
• Power rating per element: 62.5mW
• Temperature coefficient: ±200ppm/°C
• Package type: 1206 (3216 Metric) with convex, long side terminals
• Pin count: 8
• Mounting technology: Surface mount
• Compliance: RoHS3 compliant

The YC164-JR-07750RL from YAGEO meets all these electrical and mechanical specifications, enabling direct substitution in applications where the original CAY16-751J4LF is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the CAY16-751J4LF and YC164-JR-07750RL are Active status components with RoHS3 compliance. The YC164-JR-07750RL offers an extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and carries AEC-Q200 automotive qualification. Selection between these parts depends on application requirements: the CAY16-751J4LF is suitable for standard industrial and consumer applications within its temperature range, while the YC164-JR-07750RL provides additional thermal margin and automotive-grade reliability for demanding environments. The maximum seated height difference of 0.004" (0.10mm) is negligible for most PCB assembly applications.

Frequently Asked Questions (FAQ)

Q: Can YC164-JR-07750RL replace CAY16-751J4LF in all applications?

A: Yes, the YC164-JR-07750RL meets all electrical and mechanical specifications of the CAY16-751J4LF. The extended temperature range and automotive qualification of the YAGEO part provide additional capability without compromising compatibility.

Q: What is the significance of the height difference between these parts?

A: The CAY16-751J4LF has a maximum seated height of 0.024" (0.60mm) while the YC164-JR-07750RL is 0.028" (0.70mm). This 0.004" (0.10mm) difference is within standard PCB assembly tolerances and does not affect component placement or board clearance in typical applications.

Q: Are both parts suitable for automotive applications?

A: The YC164-JR-07750RL carries AEC-Q200 automotive qualification. The CAY16-751J4LF does not specify automotive qualification but remains suitable for non-automotive industrial and consumer applications.

Q: What packaging formats are available for these parts?

A: The CAY16-751J4LF is supplied in Tape & Reel (TR) format. The YC164-JR-07750RL is supplied in Cut Tape (CT) format. Both are surface mount components in 1206 package.

Q: Do these parts have identical pin configurations?

A: Yes, both parts have 8 pins with identical isolated 4-resistor network configuration and convex, long side terminal design.
