Replacement verdict
Compatible functional replacement candidate
The 5PB1102CMGI8 and 5PB1104CMG18 are both single-input, low-skew clock fanout buffers from the same 5PB11xx family, sharing identical supply voltage, output type, and package footprint. The primary distinction is the number of outputs, making the 5PB1104CMG18 a viable functional substitute for the 5PB1102CMGI8 in applications where the additional output channels are acceptable or can be left unconnected.

Frequently asked questions
What are the 5PB1102CMGI8 and 5PB1104CMG18?
The 5PB1102CMGI8 and 5PB1104CMG18 are Renesas (formerly IDT) 3.3V LVCMOS clock fanout buffers. The 5PB1102 provides 2 outputs, while the 5PB1104 provides 4 outputs. Both are offered in a 16-pin QFN package and are specified for operation over the industrial temperature range.
What is the main difference between the 5PB1102CMGI8 and 5PB1104CMG18?
The primary difference is the number of clock outputs. The 5PB1102CMGI8 is a 1-to-2 fanout buffer, whereas the 5PB1104CMG18 is a 1-to-4 fanout buffer. Both devices share the same 3.3V LVCMOS input and output signaling, package footprint, and general functional architecture.
Are the 5PB1102CMGI8 and 5PB1104CMG18 pin-compatible?
No. Although both devices are housed in a 16-pin QFN package, the 5PB1102CMGI8 uses fewer output pins than the 5PB1104CMG18. The additional outputs on the 5PB1104CMG18 occupy pins that may be unassigned or serve different functions on the 5PB1102CMGI8. A direct drop-in replacement is not possible without verifying the pinout against the respective datasheets.
Can the 5PB1104CMG18 be used as a drop-in replacement for the 5PB1102CMGI8?
No. Because the two devices have different output counts and different pin assignments, the 5PB1104CMG18 cannot be used as a direct drop-in replacement for the 5PB1102CMGI8. The system design must be reviewed to ensure that the additional outputs and any pin function differences are compatible with the target application.
What is the operating voltage and temperature range for these devices?
Both the 5PB1102CMGI8 and 5PB1104CMG18 operate from a 3.3V nominal supply and are specified for the industrial temperature range of -40°C to +85°C, as stated in the Renesas datasheets.
What output type do the 5PB1102CMGI8 and 5PB1104CMG18 provide?
Both devices provide LVCMOS-compatible clock outputs. The outputs are designed to drive terminated transmission lines and are suitable for fanout of clock signals in industrial and consumer applications.
Do the 5PB1102CMGI8 and 5PB1104CMG18 support the same input signal types?
Yes. Both devices accept LVCMOS input signals and are intended for clock distribution applications. The input structure and threshold levels are consistent across the two devices, as documented in the Renesas 5PB11xx series datasheets.
What package do the 5PB1102CMGI8 and 5PB1104CMG18 use?
Both devices are offered in a 16-pin QFN package. The package dimensions and thermal characteristics are the same for both part numbers, but the pin functions differ due to the different output counts.
