Replacement verdict
Compatible functional replacement candidate
The 5PB1110NDGI and 5PB1106CMGI are both Renesas clock fanout buffers from the same 5PB11xx family, sharing identical 1:10 and 1:6 LVCMOS output signaling, 1.8V to 3.3V supply range, and similar industrial temperature support. The primary distinction is channel count, which directly affects fanout capability and package footprint. The 5PB1110NDGI is a viable functional replacement candidate for the 5PB1106CMGI when additional output channels are acceptable and the larger package can be accommodated on the PCB.

Frequently asked questions
What are the 5PB1110NDGI and 5PB1106CMGI?
The 5PB1110NDGI and 5PB1106CMGI are Renesas (formerly IDT) 5PB series clock fanout buffers. The 5PB1110NDGI is a 1-to-10 LVCMOS clock buffer, while the 5PB1106CMGI is a 1-to-6 LVCMOS clock buffer. Both are designed for low-skew clock distribution in applications such as networking, computing, and industrial systems.
What is the difference in fanout between the 5PB1110NDGI and 5PB1106CMGI?
The 5PB1110NDGI provides 10 outputs, whereas the 5PB1106CMGI provides 6 outputs. This difference in fanout directly affects how many clock loads each device can drive without additional buffering.
Do the 5PB1110NDGI and 5PB1106CMGI have the same package type?
No. The 5PB1110NDGI is offered in a 24-pin QSOP package, while the 5PB1106CMGI is offered in a 16-pin QSOP package. The different pin counts and package sizes affect PCB layout and pin compatibility.
Are the 5PB1110NDGI and 5PB1106CMGI pin-to-pin compatible?
No. Because the 5PB1110NDGI uses a 24-pin QSOP package and the 5PB1106CMGI uses a 16-pin QSOP package, they are not pin-to-pin compatible. A direct drop-in replacement is not possible without PCB redesign.
What supply voltage do the 5PB1110NDGI and 5PB1106CMGI operate at?
Both devices operate from a 3.3 V or 2.5 V supply, depending on the specific ordering option and configuration. Designers should verify the exact voltage range in the respective Renesas datasheet for the targeted part number.
Can the 5PB1110NDGI and 5PB1106CMGI be used in the same application?
They can be used in similar clock distribution applications, but the choice depends on the required number of outputs. The 5PB1110NDGI is suitable when up to 10 clock loads must be driven, while the 5PB1106CMGI is appropriate for up to 6 loads. Other electrical and timing specifications should also be compared before substitution.
What are the typical applications for the 5PB1110NDGI and 5PB1106CMGI?
Typical applications include clock distribution in servers, storage systems, networking equipment, and industrial controllers. The 5PB1110NDGI is used where higher fanout is needed, while the 5PB1106CMGI suits designs with fewer clock loads and tighter board space constraints.
Are the 5PB1110NDGI and 5PB1106CMGI RoHS compliant?
Renesas 5PB series devices are generally offered in RoHS-compliant packages. However, compliance should be confirmed against the specific ordering part number and the latest Renesas material declaration or product change notification.
