Replacement verdict
Compatible functional replacement candidate
The 5PB1110NDGI and 5PB1106CMGK are both 1-to-6 LVCMOS clock fanout buffers from Renesas with matching 1.8V–3.3V supply range, 6 outputs, and 8-pin packages, making them strong functional replacement candidates. However, the 5PB1110NDGI offers a wider operating temperature range and a different package footprint, so validation of thermal margin and PCB layout is required before direct substitution.

Frequently asked questions
What are the 5PB1110NDGI and 5PB1106CMGK?
The 5PB1110NDGI and 5PB1106CMGK are Renesas clock fanout buffers from the 5PB11xx series. Both are low-skew, low-jitter clock distribution devices intended for applications such as PCIe, networking, and general clock buffering. The 5PB1110NDGI is a 1:10 fanout buffer, while the 5PB1106CMGK is a 1:6 fanout buffer.
What is the difference in fanout between the 5PB1110NDGI and 5PB1106CMGK?
The 5PB1110NDGI provides 10 outputs, whereas the 5PB1106CMGK provides 6 outputs. The number of outputs is the primary functional difference between these two devices.
Do the 5PB1110NDGI and 5PB1106CMGK have the same package type?
No. The 5PB1110NDGI is supplied in a 32-pin VFQFN package, while the 5PB1106CMGK is supplied in a 16-pin VFQFN package. The different pin counts and package sizes affect PCB layout and thermal performance.
Are the 5PB1110NDGI and 5PB1106CMGK pin-compatible?
No. Because the 5PB1110NDGI has 32 pins and the 5PB1106CMGK has 16 pins, they are not pin-compatible. A direct drop-in replacement is not possible without a PCB redesign.
What supply voltage do the 5PB1110NDGI and 5PB1106CMGK require?
Both devices operate from a 3.3 V nominal supply. Designers should verify the exact recommended operating voltage range and tolerances in the respective Renesas datasheets before use.
Can the 5PB1110NDGI and 5PB1106CMGK be used in the same application?
They can serve similar clock buffering functions, but the choice depends on the required number of outputs and the available board space. The 5PB1110NDGI is suitable when 10 outputs are needed, while the 5PB1106CMGK is appropriate for designs requiring only 6 outputs.
Are the 5PB1110NDGI and 5PB1106CMGK RoHS compliant?
Renesas generally offers these devices in RoHS-compliant versions. However, compliance status can vary by ordering part number and date code. Verify the specific ordering code and environmental compliance on the manufacturer or authorized distributor documentation before finalizing a design.
What is the typical application for the 5PB1110NDGI and 5PB1106CMGK?
Both are used for clock distribution in applications such as PCI Express, Ethernet, storage, and embedded systems where low skew and low additive jitter are required. The 5PB1110NDGI supports systems needing more clock loads, while the 5PB1106CMGK supports lower-output-count designs.
